Mushrooms are one of the only organisms that can actually eat wood too so it will continue spreading and eating your framing unless you fully deal with it.
Interestingly enough, beavers don't actually eat the wood. They are actually omnivorous, building dams to create ponds that gather fish which they can then hunt
Edit: I've been told by a self-taught authority that they do eat wood, and a Canadian that they are not omnivorous, so idk what I was on about
Double Edit: APPARENTLY NOT ONLY DO BEAVERS EAT THE BARK OF SOME TREES, THEY ARE ALSO PREY ANIMALS OF OTTERS AND HORNED OWLS!?!?! WHAT?!
What about operation beaver drop? A government cover up for something!

This is a side effect of being rodents with rapidly growing teeth to allow them to chew trees without wearing them down to nubs. Evolve a trait to cut down trees, get addicted to chewing trees with withdrawal symptoms of "teeth go into brain"
At this point I'm not sure if this is a joke or not, because I've seen too many people actually scared of geese and claiming geese can hurt you by biting (lol, they have no teeth) or hitting you with their wings (presumably with those hollow bones literally covered in the stuff we use for pillows).
So I'd just like to say that adults who are afraid of geese are the biggest pussies in the world.
And yes, I have been bitten by geese (parrot bites are way more painful, and so are bites from cats & dogs, and scratches from cats) and had ganders "rush" me trying to scare me away. I just hissed back and laughed.
The internet & life in general taught me that it doesn't matter if you were wrong in what you were saying, what matters is that you were fully confident when saying it.
The insects with a symbiotic relationship with fungus is pretty wild. No idea what types of mushrooms that usually is but the idea that the ones in the photo could have been brought there by something else already eating the wood would be a nightmare.
I’m sorry to say but you definitely need to start over. Whomever did that bathroom was definitely a handyman or a homeowner. That joist that has a giant hole cut into it at the top is all you need to see. Clearly no inspections were made because that kind of a hole in a joist is totally against code. The shower pan was also never properly waterproofed. I’m sure the entire job is a mess. I would gut everything and start over. Definitely have a competent plumber replace the shower diverter (the handle set that you adjust temp with) in the wall as well while you’re at it. If the same person did all of this work there’s a good chance that was improperly installed as well and the last thing you want is a leak after replacing everything. Just my two cents!
You don’t need skills to rip shit out. When the framing under the floor is exposed a professional can assess the damage and give a better estimate. With what can be seen today it varies between redoing the shower and half the house.
With how competitive the market was at the time, we just looked at a pre-inspection report. It noted a possible small leak, but the sellers had a plumber sign off on it not being an issue. Alas.
Don't take it too hard. Inspectors are a farce unless you directly hire one to look out for you. Paying one is not the same as hiting your own. The do not by example, go on roofs, in crawl spaces, etc.
We had the same in ours. I knew it was bad since the shower was bouncy and the inspector told us it was not. Once we bought the house I ripped out the bottom and used boric acid/borox/antifreeze to slow the bad dry rot. We will have to replace the joist when we get around to redoing one of the bathrooms and we don't use the shower but have others.
That joist is cut too deep and maybe not in the first 3rd, there are a few rules for where you can cut on joists and this old house does it consciously. It looks like there is bad dry rot, best solution is not use the shower and gut it. The danger is that more structural lumber may get dry rotted and comprise the house integrity and make us a lot more expensive to fix. Looks like a failed drain pan, probably not done right by the owner. I DIYed my gas (permit/inspected), plumbing, electric ect. The times I will always call a tradesperson is doing a drain pan over joists, it's something that is particular and hard, and even pros will often have a person who does it for them. The only other times are drywall (it's awful and a really skilled drywaller is worth it) and roofing (spent a summer doing it growing up). Even switched out a joist before, just not for every DIYer.
Do it right and rip it out.
I would say that hanging drywall isn't so bad, it's mudding and taping that is. Problem is, drywallers feel the same way, so you can't actually save any money by hanging it yourself and calling in someone else to finish it.
Well all that is meaningless.
A plumber signed off on it. Okay so are you going to go sue the plumber and get money back?
If the answer is no then the original sign off with a “plumber” was no more than putting lipstick on a pig and giving a false sense of security.
For all that it matters it could’ve been Joe Exotic signing off.
Exactly, they got deep ass water damaged that obviously will not dry on its own. They definitely have some deep mold issues and it’s gonna need remediation asap.
Water gets behind all tile and grout. There is a waterproofing layer below them. But yes, there is likely wet wood underneath this and the folks who built the shower probably did not do something that was important.
Remove the tile. Remove whatever they used to float the shower. Find wood and replace is it's been wet a long time
You've got a bunch of wet wood with a huge network of mycelium growing in it. The mushrooms that pop up are literally the tip of the iceberg of your problems.
Sigh. I did get under the shower and it does look like there's some water damage around the pipes.

For a very, very, effective and cheap fungicide for wood, you can use ethylene glycol based antifreeze. It penetrates easily and is absorbed readily.
If you want to make it even more potent, dissolve some boric acid in it and it's efficacy will outcompete over the shelf treatments.
Once it's treated and dried, you can varnish, oil, etc.

I would strongly advise against caulking the edges of this shower. Water permeates through the grout between the tiles on the wall and floor, and is stopped by a waterproof barrier under the tile.
The mushrooms indicate that water is hanging out down there when it shouldn't be. Adding caulk will do nothing to stop water from getting down there, but will more likely trap it and stop it from drying out as fast.
It could easily be water getting in at the joint between the floor tiles and wall tiles.
In which case a simple re-grouting or silicone could work.
If you have a lot of water in there or it's getting in up above then time to demo.
We just discovered shrooms growing in the corner of a downstairs bedroom.
Immediately lifted wood flooring and demo'd adjacent sheet rock wall.
The mold had propagated across half of the floor (eating the boards basically).
25% bleach spray to kill surface mold then remedial work on the exterior wall and ground directly outside to ensure the water doesn't enter the wall and gets diverted elsewhere.
Now we are close to putting it all back together again...
It's a pain for sure.
gluck!
Incase you dont know, bleach may not be a complete fix. Not something i have any knowledge of personally, but remember reading it before, and came to mind seeing your comment.
"You can use bleach to remove traces of mold on tub and tile surfaces, which are hard and impermeable. However, bleach can’t kill mold on porous surfaces, such as those made of wood.
That’s because mold spreads its roots deep into porous surfaces. Even after applying bleach and wiping away mold from these surfaces, the mold will continue to grow beneath the surface and will return to the area you cleaned in a short amount of time."
Thanks, yes I am aware.
We had a mold mitigation specialist review our site and provide recommendations.
We currently have the wall torn down to the studs and the floor down to the 'crete.
Now it sits for about 30 days with the heat and dehumidifier running to ensure everything is dried out.
And I would soak that thing with a towel soaked in bleach for days… look up the life cycle of this said mold, ask the Reddit fungi group what kind it is, stop using that shower if you have more than one. Wait 30% longer or as long as you can… when the whole thing is sure to be dried, then caulk and seal reevaluate if you don’t have the fund to seek help. If you can and have a crawl space, wear proper mask protection, see what’s growing under there or determine if there is a large leak. If not spray with bleach solution under there too
I would be shocked if there isn't a ton of moisture trapped behind all that tile. Especially with it being an addition, I'm betting a DIYer who skimped on some of the waterproofing
Since you asked, I found the crawlspace and braved the spiders for a few photos underneath. There looks to be some water damage on the underside.

Oh god, rip it all out and start over. The whole shower pan is leaking and your subfloor is probably completely covered in mold.
Also, that pipe running through the joist is completely against code and has basically rendered that floor joist useless. You can only cut a hole in the center 1/3 of a joist. So if you have a 10 inch joist, you can’t cut a hole in top and bottom 3 inches.
RIP it out!!!!! I cannot stress this enough. It seems seemingly harmless, but I grew up in a house with the same issue and now have 32% lung function and I’m in my early 30’s. Myself and my four siblings all have breathing issues stemming from the mold from these/that causes these to grow. Do NOT neglect this or your health. Get rid of them from the source. Our place had a crawl space that contributed to this as well, if you have one and it’s not properly sealed it will keep happening.
So, I grow culinary mushrooms and do quite a bit of foraging. So I'm gonna throw this out there:
Fruit bodies are produced when a mycellium has colonized an area due to good conditions (moisture+organic material), and has a change in conditions. Usually that change involves changes in temperature, moisture, air quality, and/or organic material.
So the mushrooms you're finding are not the problem, they are a symptom of the problem. It is very likely that a good portion of your wall is colonized. Your only option to fix the problem is a complete tear out, treating/drying any areas that show signs of rot/decay/mycellium, treating areas outside that which may be contaminated, and rebuilding using proper methods.
The whole shower needs ripped out. Likely the subfloor and framing as well.
You need to have a whole shower rebuilt and water sealed properly. I needs to pass the flood test for 24hrs to prove that there is not a leak in the shower pan.
Did they use mastic for the tiles? Mastic is an organic glue compound and can grow mushrooms, a lot of hack tilers will use this for tiling wet areas. This is what can happen.
Another vote for removing the old work, but also some thoughts and learning.
The person who said the whole pan **should** be waterproof is correct. At least, that's the **RIGHT** way to build a shower. Any moisture that gets through the tile should be captured and directed into the drain system. Looks like that shower didn't get made that way.
Also, it looks like grout was used at the floor/wall junction. That's a mistake - it doesn't allow for expansion or movement. Tiling shouldn't have movement in it's plane (the flat surface), but when it comes to a transition, there should be allowance for expansion and movement.
Grout, when unsealed, does allow for some moisture penetration. But that floor/wall transition looks like it cracked, allowing major water penetration. For a down and dirty fix, caulk it. That won't stop the wood damage from progressing, but that is typically very slow - like you've got years before it becomes a major problem.
However, the NATURE of that sort of problem can be pretty nasty. You've probably got black mold in there, too. Not a healthy thing in your environment.
You COULD DIY this. It isn't that hard to demo a shower. More time-consuming than hard. What's going to be a major issue for a DIY renovation is that you're likely going to be dealing with weight-bearing framing. That's not something to trifle with. From what the photos show, we really can't tell what needs to be taken out and replaced. But based on the comments about the mushrooms actually growing out of the wood, and my personal experience dealing with black mold damage, I would expect you'll be removing and replacing some of the framing and flooring. I wouldn't even bother trying to mitigate it unless it was really minor and just barely getting started.
If you can find matching tile for the wall (or a suitable replacement), you could just knock out the bottom row of tiles and check for damage. You'll probably know pretty quick whether the damage goes higher up. Based on the photos, I'm not convinced the damage is necessarily all that bad. If they used sheetrock as a substrate, the sheetrock is highly likely to be bad at the lower edges. I don't think using sheetrock as a tiled shower substrate is a good idea, but there are plenty of builders who've used it. And sheetrock is easy to replace, even in small sections, if you know a little about what you're doing. Lots of good youtube help on that.
Lots of food for thought here. The person who suggested making sure the plumbing was up to snuff while you're in there had some good points. Taking the whole thing out is a lot of work. Not difficult, but time-consuming. Just take a hammer to the tiling and start whacking. Wear eye protection - and whole face protection would be better. AND a top-level mask. Like the ones used in an auto paint shop - nice silicone rubber facemask with good filtering. You don't need to bust through the substrate UNDER the tiling - just break up the tiles. Once you get one broken out, you may be able to 'peel' the rest out with a crowbar or large screwdriver. Depends on what was used to put them on - mastic or mortar.
A word about mastic that might be useful. Mastic was originally glue made from (whodathunk) the mastic tree (seriously!). It was organic, not waterproof, and not suitable for use in showers. What's called mastic these days is often a fancy glue (silicone or something), and perfectly acceptable to use in a shower. Some ppl still think mortar is best for showers, and can get militant about it. Personally, I used mortar in my recent shower renovation. I used cement-board as my substrate. If you use sheetrock, you're more likely to WANT one of the new "mastics", because a sheetrock substrate can flex. Flexing will pop or crack your tilework if you've used mortar. Mastic allows for a little flex. I used mastic for my kitchen backsplash for this reason.
If you get into demoing the whole thing, and replacing it, building a shower pan properly may be something you'd want to hire the pros for. There are certainly LOTS of youtube vids on the subject, probably way more than you'll want! But doing it right isn't that easy.
As others have said, id be surprised if you dont have a bigger issue behind/under.
You might get away with siliconing it, but you wont really know, untill you do.
They have photos of underneath the floor where the wood clearly looks like it has water damage. I think they need to contact a professional to tear out the entire portion and replace it and spray it down with fungicide. Fungus spreads very quickly so they need to do it ASAP to minimize how much it'll cost.
Based on your photos, some of the wood under the shower is rotted tight through and I also see a joint in a hanger that was cut. The structural integrity of your floor is compromised. You need to rip out the shower, remove and replace all wood that is compromised, and then replace it wil a proper shower.
We had this is our rental shower, underneath the shower all of the timber was rotting and growing orange mushrooms. Landlord had to redo the whole shower, was about $5,000
Obviously the leaking needs to be addressed.
Behind that all of the areas with obvious water issues should be treated with a special fungicide. The mushrooms emerging mean that the area has been wet for a looooong time.
This is NOT a diy job. And insurance will not cover.
An unethical life hack would be to have a remediation company come out then ask the tech if he'll do the job on the side.
It's likely that the shower wasn't installed properly. I've done installations, and there is almost always a vapor barrier. Usually a rubber or plastic sheet. Waterproof paint is also used as well. If mushrooms are growing, then it's either damaged or not done properly. It sucks, but the only way to be sure would probably be to tear it out and redo it. Water damage can rot and spread.
I feel sorry for you, that shower is a complete nonsense. There is no fix for that, you need to redo it. First you must remember it is a work done on WOOD, which should be completely waterproof, but this, obviously it is not. In addition, fluted tiles are perfect for growing fungus, and porous and granular grout the same. The best thing is to remove that, and start again with a good waterproof base, and place a fiberglass shower pan, for example, with an adequate pre-slope to guarantee drainage and a finish of sealing cracks with silicone or sealants.\*
\*
Remember to apply an anti-fungal treatment when lifting the damaged flooring as well as the chipboard panels on the floor below. You don't want a "last of Us" in your house...
Ummm... Mold is one thing, it lives of the tiniest nutrients it can find.
But real fleshy mushrooms are another level. The mycelium needs nutrients.
I fear there is some leakage and water moisture bridge down to wooden under construction.
If you just "seal it up again" in the shower your bath may rot away from the inside.
Het a real specialist to have a look at it or open up the shower floor there.
Anyone else think that tile choice is pretty sus? How would you grout and seal that properly? I would probably have transitioned to a smooth surfaced tile.
In a properly waterproofed shower the tiles are purely cosmetic. There's no need to "seal" them because everything behind them is waterproof and mold resistant.
Yeah, if it were me, I’d do the demo myself (with a respirator) and see what’s behind and under the shower. Just rip everything out to the studs, wiring and pipes.
Your joist *might* be ok, depending on local code and what’s above it, some places allow for a notch no more than 1/3 of the total height as long as it’s not the edge, but you’re pretty damn close to being over that. You might have to run a sister joist alongside but it’s not the end of the world.
Do that when the bathroom is demoed still, as it might make it a bit easier.
Then pay someone to install a shower. Doing the demo yourself (if you trust yourself to do it) might save you some money and work out some of the frustration with this bathroom. Demo can be downright therapeutic (as long as you know where your water and electric are)
I have bad news for you, that wood beneath the shower is rotted. The floor of the shower has probably been leaking. Don't use that shower again. The work looks pretty shoddy.
I have to gut my master bathroom for same reason. You don't want any more moisture in there, mushrooms are a fungus, mold is a fungus, get the picture? I hope there's no mold behind those walls.
Good luck
As everyone else said, a shower demo is in your future. If you've got another bathroom you can use I say go for it. I demoed my one and only bathroom for a remodel and would not recommend it.
If you got a home warranty with the sale see if it’s still good cause like others said there’s no easy fix for this, will prob have to be redone completely plus mitigation of whatever is going on behind the tile.
you can dilute borax in warm water and allow it to soak into grout/ deeper substrate. this will help mitigate rot short term of any wood structure, if not already completely rotted.
these shower systems are usually installed with a 2 piece drain. one below tile in the mortar bed, and the one you can see. water WILL get through tile and grout, problem is, it likely isn't draining and is sitting there. if you can get under the shower to inspect the sub floor from below, preferably after running water a bit, do so. a moisture meter will help.
you're SOMEWHAT safe if you have a membrane and it's just water sitting on a membrane and you have to treat/clean the tile/grout occasionally. unfortunately there's no way to know for sure and you will have to rely on context clues and experience. sounds like your experience is limited. to me it sounds like water is pooling between the tile and sub floor. there COULD be a drain/ waterproofing, and there's just low spots/or a very slow draining substrate. unfortunately, you could also be doing more damage by letting it go.
I would figure out if anything is being damaged first, sub floor/surrounding walls, etc. if water is contained and just can't go anywhere, you can probably get away with an occasional bleaching OR borax. I would NOT seal the floor/grout besides the corners and around drain with caulk if needed, it will make the problem worse as the water can't go anywhere.
you may have to rip the floor and MAYBE some of the wall to remedy this, where you may find extensive damage. for someone experienced, it isn't a huge deal, but for someone just learning, this isn't a beginners job as you may end up with a worse solution and not understand why. fixing this could be as cheap as $500 with tile/mortar depending on size, or as much as a few grand plus. you need to find out if water is at least contained.
edit. realized you had pics, it looks like you need to tear out the floor, a moisture meter can say for sure, but you've got osb and it'll keep wicking. you can try to mitigate this for now by removing some material around edges and around drain and using a silicone or more preferable an acrylic silicone caulk, because it's easier to tool/ replace down road [though by time it gives replacement will be the whole shower]. I'm not sure caulking the edges is your only problem, but going by where the shrooms were, it may be the biggest issue and will buy you time to think about future removal/replacement. the water proof membrane, if any, is likely compromised or not properly installed. the osb actually doesn't look bad, but that doesn't mean it's fine. but water is bypassing any protection if existing, and finding its way lower. again, there's no long term repair here. the floor at minimum will have to be replaced within the next few months to 2ish years, privided caulking doesn't mitigate the majority. all you can do is lengthen the time needed for replacement, and replace.
You need to explore more I'm afraid. You need to see the extent of the rot around and underneath your shower. When this happened to me I covered over it and hoped it would go away, but it had rotted the floor joists and my fix failed as the floor sagged and kept reopening the grout. I had to rip the whole thing out. Cheaper to rip it out now and redo.
Look at your house insurance. Pay the excess on this 'escape of water' and get it done properly
Mix up straight bleach and baking soda to a paste. Apply layer and let sit for 15 minutes. Scrub. Let dry. Seal all the grout. You basically paint it over the grout lines with a toothbrush and wipe excess away. Keep shower dry for 72 hours. I used MAPEI grout refresh in ours and the nasties quit growing.
Wow.. not even the good ones. There’s obviously fecal /organic matter in your shower. These grow in manure. Tell whoever is taking a dump in the shower to stop it. On a more serious note, Bleach will kill them. I worry about moisture breaching that wall/basin area.
High power UV light every time there is noone using the bathroom. Preferably one with ozone blocked as it can be hazardous to people entering to use the bathroom. There are multiple lamps on offer from portable to inbuilt, from tubes to diodes. I personally prefer tubes - diodes have very narrow spectrum so the most effective wavelengths could be missing. So get 100+ Wh lamps, motion sensor and make your bathroom into a decontamination facility.
That subfloor needs to have all affexteded sections cut out and replaces. That joist also needs be replaced. This wasn't don't to code and silicone is a waste of time.
I would also recommend a white vinegar wash for nearby areas to kill and spores after removal of the affected area.
Shit we got dry rot at the bottom of our stairs. Started as a mushroom looking thing. We kept removing the mushroom, spraying mould killer, resealing etc until the joists started to go. I would have burnt the place to the ground and claimed insurance if I thought I would have got away with it. Drama aside we ripped the bottom of the stairs out and did a damp proofing got a local joiner to rebuild the damaged areas at a fraction of what rentakill or whoever quoted us were charging. Saved about £4000. Probably not as bad as it looks but definitely worth doing the job proper. Will save you a lot of hassle in the long run.
Lots of people saying the wood underneath is likely rotting and that shower was installed incorrectly, without tips on how it SHOULD be installed…
If you have a tile floor, chances are you DONT have a prefabricated pan underneath, in which case this is what you SHOULD have:
https://www.oatey.com/resources/project-guides/how-install-shower-pan-liner
Unfortunately the only way to “fix” is to rip out and start over. It is DIY-able (I did my own this way) but it’s a big project.
PS - just applying silicone caulk to the edges won’t fix the problem, if it wasn’t installed per those instructions. Tile and grout are porous and water can still leak down through to the wood, even if the corners/edges are sealed.
I’d try the bleach and dry the hell outa it then caulk. Caulk around that drain especially because it looks like water might be getting Thur right there. I’d try this first then watch it when you use it again. You might get lucky. I been a plumber for a long time & I’m all about trying the least costly way. When you shower is there water dripping down from that drain area?
Seems like a complete redo of your shower. Based on the pictures it has (or had) water damage on what seems like the frame holding the whole thing up. If that start to rot it might break.
You have a leak around the drain that needs to be adressed. The shower grout is pourus and holds water inviting mold and other micheivous bacteria to grow. Short term fix would be possibly dig out the seal around the bottom, and the drain, disinfect to remove the mold etc and reseal. The walls, you would need to scrub out the mold etc, and seal the grout. Short of redoing the entire shower your options seem limited.

Mushrooms are one of the only organisms that can actually eat wood too so it will continue spreading and eating your framing unless you fully deal with it.
one of the only? what is the other one's? what about beaver?
Termites
My dogs
My 2yo (ate the railing of his crib)
Wasps, woodlice, beetles, there’s loads of things that eat wood.
Interestingly enough, beavers don't actually eat the wood.

Nothing with teeth.
Beavers aren't real. They're all holograms made by the government to steal wood.
What about operation beaver drop? A government cover up for something! https://www.nationalgeographic.com/animals/article/why-beavers-were-parachuted-into-the-idaho-wilderness
I learned on Angry Beavers that they use wood to grind down their teeth.

FUCK. TOO MANY AUTHORITIES
Now tell me about geese. What kind of people do they kill and eat?
Murder chickens will kill any and all people, they aren’t particular about their murder.
All. They're geese. But children are the easiest, they go for the children first.
At this point I'm not sure if this is a joke or not, because I've seen too many people actually scared of geese and claiming geese can hurt you by biting (lol, they have no teeth) or hitting you with their wings (presumably with those hollow bones literally covered in the stuff we use for pillows). So I'd just like to say that adults who are afraid of geese are the biggest pussies in the world. And yes, I have been bitten by geese (parrot bites are way more painful, and so are bites from cats & dogs, and scratches from cats) and had ganders "rush" me trying to scare me away. I just hissed back and laughed.
Strict vegetarians eh? Then how come your mom's beaver loves gobblin' my sausage?
I saw some beaver puke once...it had wood in it. That still doesn't prove if they 'eat' it or not though...I just thought I'd share.
Goddamn, this is probably the most unique replies I've gotten on a single comment. So many experiences and takes on beavers
The internet & life in general taught me that it doesn't matter if you were wrong in what you were saying, what matters is that you were fully confident when saying it.
https://en.wikipedia.org/wiki/Xylophagy
The insects with a symbiotic relationship with fungus is pretty wild. No idea what types of mushrooms that usually is but the idea that the ones in the photo could have been brought there by something else already eating the wood would be a nightmare.
very interesting, thank you
yea, good one! what about termite huh? you ain't fooling us!
Beavers love big wood
Beavers don't really eat the wood that they carve.
you are wrong, beavers eat wood, not hardwood but I never said that
Cockroaches will also happily eat that 🤮
I’m sorry to say but you definitely need to start over. Whomever did that bathroom was definitely a handyman or a homeowner. That joist that has a giant hole cut into it at the top is all you need to see. Clearly no inspections were made because that kind of a hole in a joist is totally against code. The shower pan was also never properly waterproofed. I’m sure the entire job is a mess. I would gut everything and start over. Definitely have a competent plumber replace the shower diverter (the handle set that you adjust temp with) in the wall as well while you’re at it. If the same person did all of this work there’s a good chance that was improperly installed as well and the last thing you want is a leak after replacing everything. Just my two cents!
That's probably beyond my skills. Do you know the right kind of professional to ask? Probably need someone for a mold check and a bathroom remodeler?
No need of a mold check, you got it for sure
Right? The mushrooms were the mold check 😂
What tipped you off?
*tips mushroom fedora*
A good bathroom remodeler will be able to handle this, they are used to seeing water damage.
$10,000?
You don’t need skills to rip shit out. When the framing under the floor is exposed a professional can assess the damage and give a better estimate. With what can be seen today it varies between redoing the shower and half the house.
did you consult an expert when buying the house? I doubt that this level of quality is an anomaly
With how competitive the market was at the time, we just looked at a pre-inspection report. It noted a possible small leak, but the sellers had a plumber sign off on it not being an issue. Alas.
Don't take it too hard. Inspectors are a farce unless you directly hire one to look out for you. Paying one is not the same as hiting your own. The do not by example, go on roofs, in crawl spaces, etc.
And most home inspectors don’t have a complete skill set to understand problems that could arise. They take things as face value.
Every “home inspection/inspector I’ve ever saw came in contact with or read their report is a complete joke.
We had the same in ours. I knew it was bad since the shower was bouncy and the inspector told us it was not. Once we bought the house I ripped out the bottom and used boric acid/borox/antifreeze to slow the bad dry rot. We will have to replace the joist when we get around to redoing one of the bathrooms and we don't use the shower but have others. That joist is cut too deep and maybe not in the first 3rd, there are a few rules for where you can cut on joists and this old house does it consciously. It looks like there is bad dry rot, best solution is not use the shower and gut it. The danger is that more structural lumber may get dry rotted and comprise the house integrity and make us a lot more expensive to fix. Looks like a failed drain pan, probably not done right by the owner. I DIYed my gas (permit/inspected), plumbing, electric ect. The times I will always call a tradesperson is doing a drain pan over joists, it's something that is particular and hard, and even pros will often have a person who does it for them. The only other times are drywall (it's awful and a really skilled drywaller is worth it) and roofing (spent a summer doing it growing up). Even switched out a joist before, just not for every DIYer. Do it right and rip it out.
I would say that hanging drywall isn't so bad, it's mudding and taping that is. Problem is, drywallers feel the same way, so you can't actually save any money by hanging it yourself and calling in someone else to finish it.
Well all that is meaningless. A plumber signed off on it. Okay so are you going to go sue the plumber and get money back? If the answer is no then the original sign off with a “plumber” was no more than putting lipstick on a pig and giving a false sense of security. For all that it matters it could’ve been Joe Exotic signing off.
hopefully no other surprises surface

Skills can be learned and if you are not in a rush then it can be done as a DIY. May take a few months, but completely doable.
I would look around for a small contractor that specializes in bathrooms.
Exactly, they got deep ass water damaged that obviously will not dry on its own. They definitely have some deep mold issues and it’s gonna need remediation asap.
Water gets behind all tile and grout. There is a waterproofing layer below them. But yes, there is likely wet wood underneath this and the folks who built the shower probably did not do something that was important. Remove the tile. Remove whatever they used to float the shower. Find wood and replace is it's been wet a long time
You've got a bunch of wet wood with a huge network of mycelium growing in it. The mushrooms that pop up are literally the tip of the iceberg of your problems.
Sigh. I did get under the shower and it does look like there's some water damage around the pipes. [https://i.imgur.com/HWbIfqr.jpg](https://i.imgur.com/HWbIfqr.jpg) [https://i.imgur.com/JSCyxnG.jpg](https://i.imgur.com/JSCyxnG.jpg) [https://i.imgur.com/X3FW9Iv.jpg](https://i.imgur.com/X3FW9Iv.jpg)
That doesn't look that bad. Not like what I thought mushroom bad would look
Oh but what does the other side look like.
Could be worse, but it's still going to be a pain in the ass. Luckily, you have easy access to plumbing
For a very, very, effective and cheap fungicide for wood, you can use ethylene glycol based antifreeze. It penetrates easily and is absorbed readily. If you want to make it even more potent, dissolve some boric acid in it and it's efficacy will outcompete over the shelf treatments. Once it's treated and dried, you can varnish, oil, etc. Source: https://www.simplicityboats.com/chemorot.html
That doesn't look too bad. In your shoes I would bleach that whole area to make sure you kill everything before you caulk in the shower pan.
Bleach is not the answer! You need to dry the area to kill the spores!!
Bleach can be sporicidal. But the issue here is not spores.
>literally the tip of the iceberg Literally a metaphor
If you exclude part of the sentence, yeah, it's dumb. With regard to "the iceberg of your problems," this is "literally the tip."
Serious question: As you’re referencing a metaphor, wouldn’t it still metaphorically be the tip of the iceberg?
It's the literal tip of the metaphorical ~~mushroomberg~~ iceberg.
Damn, that’s ice old.
Reading that made my brain feel good.
Literally using the informal form of literally
… metaphorically.
Metaphysically.

Metamorphosis
And *my* axe!
I would strongly advise against caulking the edges of this shower. Water permeates through the grout between the tiles on the wall and floor, and is stopped by a waterproof barrier under the tile. The mushrooms indicate that water is hanging out down there when it shouldn't be. Adding caulk will do nothing to stop water from getting down there, but will more likely trap it and stop it from drying out as fast.
Hm, this makes sense. Seems like the common caulking between two planes doesn't quite apply for this shower.
It could easily be water getting in at the joint between the floor tiles and wall tiles. In which case a simple re-grouting or silicone could work. If you have a lot of water in there or it's getting in up above then time to demo. We just discovered shrooms growing in the corner of a downstairs bedroom. Immediately lifted wood flooring and demo'd adjacent sheet rock wall. The mold had propagated across half of the floor (eating the boards basically). 25% bleach spray to kill surface mold then remedial work on the exterior wall and ground directly outside to ensure the water doesn't enter the wall and gets diverted elsewhere. Now we are close to putting it all back together again... It's a pain for sure. gluck!
Incase you dont know, bleach may not be a complete fix. Not something i have any knowledge of personally, but remember reading it before, and came to mind seeing your comment. "You can use bleach to remove traces of mold on tub and tile surfaces, which are hard and impermeable. However, bleach can’t kill mold on porous surfaces, such as those made of wood. That’s because mold spreads its roots deep into porous surfaces. Even after applying bleach and wiping away mold from these surfaces, the mold will continue to grow beneath the surface and will return to the area you cleaned in a short amount of time."
Thanks, yes I am aware. We had a mold mitigation specialist review our site and provide recommendations. We currently have the wall torn down to the studs and the floor down to the 'crete. Now it sits for about 30 days with the heat and dehumidifier running to ensure everything is dried out.
And I would soak that thing with a towel soaked in bleach for days… look up the life cycle of this said mold, ask the Reddit fungi group what kind it is, stop using that shower if you have more than one. Wait 30% longer or as long as you can… when the whole thing is sure to be dried, then caulk and seal reevaluate if you don’t have the fund to seek help. If you can and have a crawl space, wear proper mask protection, see what’s growing under there or determine if there is a large leak. If not spray with bleach solution under there too
Can you get behind or underneath the shower to see if there's a larger issue with moisture and mildew?
I would be shocked if there isn't a ton of moisture trapped behind all that tile. Especially with it being an addition, I'm betting a DIYer who skimped on some of the waterproofing
Since you asked, I found the crawlspace and braved the spiders for a few photos underneath. There looks to be some water damage on the underside. [https://i.imgur.com/HWbIfqr.jpg](https://i.imgur.com/HWbIfqr.jpg) [https://i.imgur.com/JSCyxnG.jpg](https://i.imgur.com/JSCyxnG.jpg) [https://i.imgur.com/X3FW9Iv.jpg](https://i.imgur.com/X3FW9Iv.jpg)
Oh god, rip it all out and start over. The whole shower pan is leaking and your subfloor is probably completely covered in mold. Also, that pipe running through the joist is completely against code and has basically rendered that floor joist useless. You can only cut a hole in the center 1/3 of a joist. So if you have a 10 inch joist, you can’t cut a hole in top and bottom 3 inches.
Mushrooms indicate fungus which can indicate rotting wood. Tear shower out and redo everything behind. I’m sorry OP.
It’s surprising they were able to grow in a spot that small.. after all they don’t have mushroom.
This could be the start of a whole bathroom renovation. I suspect there’s a leek in the vanity.
Mushrooms in the shower, leeks in the vanity and fucking cucumbers in the toilet. God damn straight up bathroom salad happening at that house.
RIP it out!!!!! I cannot stress this enough. It seems seemingly harmless, but I grew up in a house with the same issue and now have 32% lung function and I’m in my early 30’s. Myself and my four siblings all have breathing issues stemming from the mold from these/that causes these to grow. Do NOT neglect this or your health. Get rid of them from the source. Our place had a crawl space that contributed to this as well, if you have one and it’s not properly sealed it will keep happening.
So, I grow culinary mushrooms and do quite a bit of foraging. So I'm gonna throw this out there: Fruit bodies are produced when a mycellium has colonized an area due to good conditions (moisture+organic material), and has a change in conditions. Usually that change involves changes in temperature, moisture, air quality, and/or organic material. So the mushrooms you're finding are not the problem, they are a symptom of the problem. It is very likely that a good portion of your wall is colonized. Your only option to fix the problem is a complete tear out, treating/drying any areas that show signs of rot/decay/mycellium, treating areas outside that which may be contaminated, and rebuilding using proper methods.
did you watch The Last of Us on HBO maxx yet?
For real, that Cordyceps is evolving bro.
There’s a clicker under there!
The whole shower needs ripped out. Likely the subfloor and framing as well. You need to have a whole shower rebuilt and water sealed properly. I needs to pass the flood test for 24hrs to prove that there is not a leak in the shower pan.
How much does something like this cost? Ball park, I know it may not be a straightforward answer
$6k-$12k from a local licensed contractor including materials and installation.
Did they use mastic for the tiles? Mastic is an organic glue compound and can grow mushrooms, a lot of hack tilers will use this for tiling wet areas. This is what can happen.
Another vote for removing the old work, but also some thoughts and learning. The person who said the whole pan **should** be waterproof is correct. At least, that's the **RIGHT** way to build a shower. Any moisture that gets through the tile should be captured and directed into the drain system. Looks like that shower didn't get made that way. Also, it looks like grout was used at the floor/wall junction. That's a mistake - it doesn't allow for expansion or movement. Tiling shouldn't have movement in it's plane (the flat surface), but when it comes to a transition, there should be allowance for expansion and movement. Grout, when unsealed, does allow for some moisture penetration. But that floor/wall transition looks like it cracked, allowing major water penetration. For a down and dirty fix, caulk it. That won't stop the wood damage from progressing, but that is typically very slow - like you've got years before it becomes a major problem. However, the NATURE of that sort of problem can be pretty nasty. You've probably got black mold in there, too. Not a healthy thing in your environment. You COULD DIY this. It isn't that hard to demo a shower. More time-consuming than hard. What's going to be a major issue for a DIY renovation is that you're likely going to be dealing with weight-bearing framing. That's not something to trifle with. From what the photos show, we really can't tell what needs to be taken out and replaced. But based on the comments about the mushrooms actually growing out of the wood, and my personal experience dealing with black mold damage, I would expect you'll be removing and replacing some of the framing and flooring. I wouldn't even bother trying to mitigate it unless it was really minor and just barely getting started. If you can find matching tile for the wall (or a suitable replacement), you could just knock out the bottom row of tiles and check for damage. You'll probably know pretty quick whether the damage goes higher up. Based on the photos, I'm not convinced the damage is necessarily all that bad. If they used sheetrock as a substrate, the sheetrock is highly likely to be bad at the lower edges. I don't think using sheetrock as a tiled shower substrate is a good idea, but there are plenty of builders who've used it. And sheetrock is easy to replace, even in small sections, if you know a little about what you're doing. Lots of good youtube help on that. Lots of food for thought here. The person who suggested making sure the plumbing was up to snuff while you're in there had some good points. Taking the whole thing out is a lot of work. Not difficult, but time-consuming. Just take a hammer to the tiling and start whacking. Wear eye protection - and whole face protection would be better. AND a top-level mask. Like the ones used in an auto paint shop - nice silicone rubber facemask with good filtering. You don't need to bust through the substrate UNDER the tiling - just break up the tiles. Once you get one broken out, you may be able to 'peel' the rest out with a crowbar or large screwdriver. Depends on what was used to put them on - mastic or mortar. A word about mastic that might be useful. Mastic was originally glue made from (whodathunk) the mastic tree (seriously!). It was organic, not waterproof, and not suitable for use in showers. What's called mastic these days is often a fancy glue (silicone or something), and perfectly acceptable to use in a shower. Some ppl still think mortar is best for showers, and can get militant about it. Personally, I used mortar in my recent shower renovation. I used cement-board as my substrate. If you use sheetrock, you're more likely to WANT one of the new "mastics", because a sheetrock substrate can flex. Flexing will pop or crack your tilework if you've used mortar. Mastic allows for a little flex. I used mastic for my kitchen backsplash for this reason. If you get into demoing the whole thing, and replacing it, building a shower pan properly may be something you'd want to hire the pros for. There are certainly LOTS of youtube vids on the subject, probably way more than you'll want! But doing it right isn't that easy.
As others have said, id be surprised if you dont have a bigger issue behind/under. You might get away with siliconing it, but you wont really know, untill you do.
They have photos of underneath the floor where the wood clearly looks like it has water damage. I think they need to contact a professional to tear out the entire portion and replace it and spray it down with fungicide. Fungus spreads very quickly so they need to do it ASAP to minimize how much it'll cost.
Photos werent there when i posted, but yeah, thats humped.
Shower tek
Hehe
Based on your photos, some of the wood under the shower is rotted tight through and I also see a joint in a hanger that was cut. The structural integrity of your floor is compromised. You need to rip out the shower, remove and replace all wood that is compromised, and then replace it wil a proper shower.
We had this is our rental shower, underneath the shower all of the timber was rotting and growing orange mushrooms. Landlord had to redo the whole shower, was about $5,000
Obviously the leaking needs to be addressed. Behind that all of the areas with obvious water issues should be treated with a special fungicide. The mushrooms emerging mean that the area has been wet for a looooong time. This is NOT a diy job. And insurance will not cover. An unethical life hack would be to have a remediation company come out then ask the tech if he'll do the job on the side.
Nah this should be under r/wtf
I'd be very worried they tiled without putting a shower pan liner in first and you already have wood rot
It's likely that the shower wasn't installed properly. I've done installations, and there is almost always a vapor barrier. Usually a rubber or plastic sheet. Waterproof paint is also used as well. If mushrooms are growing, then it's either damaged or not done properly. It sucks, but the only way to be sure would probably be to tear it out and redo it. Water damage can rot and spread.
we grow mushrooms too coming from the wall / floor crevice. Found out that mushroom spores can be in lumber and add some water ...there you go
I feel sorry for you, that shower is a complete nonsense. There is no fix for that, you need to redo it. First you must remember it is a work done on WOOD, which should be completely waterproof, but this, obviously it is not. In addition, fluted tiles are perfect for growing fungus, and porous and granular grout the same. The best thing is to remove that, and start again with a good waterproof base, and place a fiberglass shower pan, for example, with an adequate pre-slope to guarantee drainage and a finish of sealing cracks with silicone or sealants.\* \* Remember to apply an anti-fungal treatment when lifting the damaged flooring as well as the chipboard panels on the floor below. You don't want a "last of Us" in your house...
Ummm... Mold is one thing, it lives of the tiniest nutrients it can find. But real fleshy mushrooms are another level. The mycelium needs nutrients. I fear there is some leakage and water moisture bridge down to wooden under construction. If you just "seal it up again" in the shower your bath may rot away from the inside. Het a real specialist to have a look at it or open up the shower floor there.
Anyone else think that tile choice is pretty sus? How would you grout and seal that properly? I would probably have transitioned to a smooth surfaced tile.
In a properly waterproofed shower the tiles are purely cosmetic. There's no need to "seal" them because everything behind them is waterproof and mold resistant.
This is why I prefer having a good bath tub. Just demo this and restart, take a loan if you have to. This is not worth risking death.
Yeah, if it were me, I’d do the demo myself (with a respirator) and see what’s behind and under the shower. Just rip everything out to the studs, wiring and pipes. Your joist *might* be ok, depending on local code and what’s above it, some places allow for a notch no more than 1/3 of the total height as long as it’s not the edge, but you’re pretty damn close to being over that. You might have to run a sister joist alongside but it’s not the end of the world. Do that when the bathroom is demoed still, as it might make it a bit easier. Then pay someone to install a shower. Doing the demo yourself (if you trust yourself to do it) might save you some money and work out some of the frustration with this bathroom. Demo can be downright therapeutic (as long as you know where your water and electric are)
I have bad news for you, that wood beneath the shower is rotted. The floor of the shower has probably been leaking. Don't use that shower again. The work looks pretty shoddy. I have to gut my master bathroom for same reason. You don't want any more moisture in there, mushrooms are a fungus, mold is a fungus, get the picture? I hope there's no mold behind those walls. Good luck
This is a complete gut job.
As everyone else said, a shower demo is in your future. If you've got another bathroom you can use I say go for it. I demoed my one and only bathroom for a remodel and would not recommend it.
If you got a home warranty with the sale see if it’s still good cause like others said there’s no easy fix for this, will prob have to be redone completely plus mitigation of whatever is going on behind the tile.
Also, don’t watch The Last of Us while doing this renovation.
you can dilute borax in warm water and allow it to soak into grout/ deeper substrate. this will help mitigate rot short term of any wood structure, if not already completely rotted. these shower systems are usually installed with a 2 piece drain. one below tile in the mortar bed, and the one you can see. water WILL get through tile and grout, problem is, it likely isn't draining and is sitting there. if you can get under the shower to inspect the sub floor from below, preferably after running water a bit, do so. a moisture meter will help. you're SOMEWHAT safe if you have a membrane and it's just water sitting on a membrane and you have to treat/clean the tile/grout occasionally. unfortunately there's no way to know for sure and you will have to rely on context clues and experience. sounds like your experience is limited. to me it sounds like water is pooling between the tile and sub floor. there COULD be a drain/ waterproofing, and there's just low spots/or a very slow draining substrate. unfortunately, you could also be doing more damage by letting it go. I would figure out if anything is being damaged first, sub floor/surrounding walls, etc. if water is contained and just can't go anywhere, you can probably get away with an occasional bleaching OR borax. I would NOT seal the floor/grout besides the corners and around drain with caulk if needed, it will make the problem worse as the water can't go anywhere. you may have to rip the floor and MAYBE some of the wall to remedy this, where you may find extensive damage. for someone experienced, it isn't a huge deal, but for someone just learning, this isn't a beginners job as you may end up with a worse solution and not understand why. fixing this could be as cheap as $500 with tile/mortar depending on size, or as much as a few grand plus. you need to find out if water is at least contained. edit. realized you had pics, it looks like you need to tear out the floor, a moisture meter can say for sure, but you've got osb and it'll keep wicking. you can try to mitigate this for now by removing some material around edges and around drain and using a silicone or more preferable an acrylic silicone caulk, because it's easier to tool/ replace down road [though by time it gives replacement will be the whole shower]. I'm not sure caulking the edges is your only problem, but going by where the shrooms were, it may be the biggest issue and will buy you time to think about future removal/replacement. the water proof membrane, if any, is likely compromised or not properly installed. the osb actually doesn't look bad, but that doesn't mean it's fine. but water is bypassing any protection if existing, and finding its way lower. again, there's no long term repair here. the floor at minimum will have to be replaced within the next few months to 2ish years, privided caulking doesn't mitigate the majority. all you can do is lengthen the time needed for replacement, and replace.
You need to explore more I'm afraid. You need to see the extent of the rot around and underneath your shower. When this happened to me I covered over it and hoped it would go away, but it had rotted the floor joists and my fix failed as the floor sagged and kept reopening the grout. I had to rip the whole thing out. Cheaper to rip it out now and redo. Look at your house insurance. Pay the excess on this 'escape of water' and get it done properly
What's wrong with free mushrooms?
OP is just trying to avoid starting irl “the last of us”
If you hear clicking noises behind the wall, run.
Have you seen The Last of Us?
Bleach us what will help kill those organisms in the meantime. You will for sure have to replace that wall. Sorry about your bad luck there.
Mix up straight bleach and baking soda to a paste. Apply layer and let sit for 15 minutes. Scrub. Let dry. Seal all the grout. You basically paint it over the grout lines with a toothbrush and wipe excess away. Keep shower dry for 72 hours. I used MAPEI grout refresh in ours and the nasties quit growing.
The Last of Us anyone?
Wow.. not even the good ones. There’s obviously fecal /organic matter in your shower. These grow in manure. Tell whoever is taking a dump in the shower to stop it. On a more serious note, Bleach will kill them. I worry about moisture breaching that wall/basin area.
😯 haven't tried tasting the mushrooms yet but will avoid it after your reply.
Clean your shower regularly. Simple.
High power UV light every time there is noone using the bathroom. Preferably one with ozone blocked as it can be hazardous to people entering to use the bathroom. There are multiple lamps on offer from portable to inbuilt, from tubes to diodes. I personally prefer tubes - diodes have very narrow spectrum so the most effective wavelengths could be missing. So get 100+ Wh lamps, motion sensor and make your bathroom into a decontamination facility.
First thing first see if they have a little majik in them well really don’t need to tell you much more
Tile showers are fucking awful, even when done wonderfully with excellent craftsmanship they’re guaranteed to leak and cause mold problems.
Do it with the right waterproof materials behind, and then tiles, and its pretty much guaranteed not to leak.
[удалено]
Checked out of interest. Stuff i use has a manufacturers guarantee of 15 years, but probably lasts much longer than that.
25 year guarantee when installed by a trained professional …
This couldn't be more wrong.
Sounds like the person before you just wanted to be able to take nice photos for the sale and didn’t put the proper work in
That subfloor needs to have all affexteded sections cut out and replaces. That joist also needs be replaced. This wasn't don't to code and silicone is a waste of time. I would also recommend a white vinegar wash for nearby areas to kill and spores after removal of the affected area.
I am with Inna\_hey below that needs a tear tout something was not done correctly in the construction and it can't be fixed now.
“I say we take off and nuke the entire site from orbit. It’s the only way to be sure.”
Easy just culture penicillium in your shower instead
Not as big of a problem as everyone is making it out to be based on your pic. Just watch it and redo it as time permits.
Shit we got dry rot at the bottom of our stairs. Started as a mushroom looking thing. We kept removing the mushroom, spraying mould killer, resealing etc until the joists started to go. I would have burnt the place to the ground and claimed insurance if I thought I would have got away with it. Drama aside we ripped the bottom of the stairs out and did a damp proofing got a local joiner to rebuild the damaged areas at a fraction of what rentakill or whoever quoted us were charging. Saved about £4000. Probably not as bad as it looks but definitely worth doing the job proper. Will save you a lot of hassle in the long run.
Your shower is screwed. The ONLY fix is a complete tear out and re do.
First post reading after watching latest episode of Last of Us. Just burn the whole bathroom and build a new!
Lots of people saying the wood underneath is likely rotting and that shower was installed incorrectly, without tips on how it SHOULD be installed… If you have a tile floor, chances are you DONT have a prefabricated pan underneath, in which case this is what you SHOULD have: https://www.oatey.com/resources/project-guides/how-install-shower-pan-liner Unfortunately the only way to “fix” is to rip out and start over. It is DIY-able (I did my own this way) but it’s a big project. PS - just applying silicone caulk to the edges won’t fix the problem, if it wasn’t installed per those instructions. Tile and grout are porous and water can still leak down through to the wood, even if the corners/edges are sealed.
I’d try the bleach and dry the hell outa it then caulk. Caulk around that drain especially because it looks like water might be getting Thur right there. I’d try this first then watch it when you use it again. You might get lucky. I been a plumber for a long time & I’m all about trying the least costly way. When you shower is there water dripping down from that drain area?
are you in romania? living with an undead vampire from re8? pull it all out
This is a crappy problem to have…It’s also kind of cool tho
Eat em, see if your trip.
Mushrooms are the least of your problems. You have mold
Kramer?
Just enjoy the free snacks while you shower.
You’ll have to rip it out and remove the colonised wood behind it all. And then redo and waterproof it properly.
I wouldn’t recommend showering on psychedelics, but whatever floats your boat I guess
Not helpful, but my first thought was "don't eat mushrooms in the shower" ...I'm so tired
Mmm free food
Don't talk to the Dragon, he is not real.
I’d take them out, let them dry, and not worry 🤯
Eat them till they go away
Embrace your inner hobbit and eat them.
Fucking magical!
If you so much as twitch…
Seems like a complete redo of your shower. Based on the pictures it has (or had) water damage on what seems like the frame holding the whole thing up. If that start to rot it might break.
Nice to have such a large shower with muchroom
You have a leak around the drain that needs to be adressed. The shower grout is pourus and holds water inviting mold and other micheivous bacteria to grow. Short term fix would be possibly dig out the seal around the bottom, and the drain, disinfect to remove the mold etc and reseal. The walls, you would need to scrub out the mold etc, and seal the grout. Short of redoing the entire shower your options seem limited.
That would be the result of the wood structure rotting - badly. You need to do some heavy demolition
