Floor got wet and rotted in front of shower
Help!
I am trying a DIY repair job of the area in front of my stand up shower. I cut the floor open, removed the wet insulation, etc. The problem I have is the plywood (or pressboard in this case) goes under the wall to the left (in photo) and up under the shower for a couple of inches. I need to remove that on both sides and install the new plywood. My problem is properly removing the plywood and installing the new. It is underneath the 2X4s, so unless I cut a hole in my ceiling from below, I won't be able to re-attach if I'm even thinking correctly. There was also a cement like corner at the corner of my shower that was connected to a small piece of plywood (it fell down on it's own) Any ideas?? I've been googling for 2 days, lol. http://home.austin.rr.com/pcprodigy/a.JPG http://home.austin.rr.com/pcprodigy/b.JPG http://home.austin.rr.com/pcprodigy/c.JPG http://home.austin.rr.com/pcprodigy/d.JPG http://home.austin.rr.com/pcprodigy/e.JPG http://home.austin.rr.com/pcprodigy/f.JPG http://home.austin.rr.com/pcprodigy/g.JPG Thanks!!!!!

The wood under the shower base is probably rotted out to the point it may collapse on you sometime in the near furture. Pain in the butt and could be a costly job, but you really should do it right so you won't have problems again in the future.... |

If the floor was a single layer under the vinyl or tile whatever, what you probably have is one of those 'all in one' subfloor systems that were popular very briefly 20-some years ago. Not plywood, not chipboard, but related to both. Stuff was supposed to be a labor saver during construction, but as you have found out, damn hard to repair. When I was house shopping, I passed up an otherwise interesting house to avoid the stuff. No great ideas to offer. Short of a major remodel to repair it properly, fake it as best you can. Cut the stuff as close to wall as you can, pick out as much of the rot as possible from under the plate, stabilize with epoxy or whatever, and shove some blocks in there if possible. To hold the new plywood subfloor, screw 2x cleats to the joists wherever possible, and work some joist-to-joist blocks in under the shower. It won't be easy, and whoever fixes it right in twenty years will laugh, but it will work. Those metal nailer plates they sell for decks, and a screw shooter, can be handy in spots too tight to swing a hammer. Unless ceiling below has a texture finish or something, probably be less labor to open it up for access. That drywall did get wet, so is damaged anyway. Not sure what you mean about the cement-like corner ; didn't see that in the pictures. Personally, I'd go ahead and finish gutting bathroom, and get it over with. Looks like you have half the demo done already. If your budget won't cover a new tile job, some of the old-work shower kits (3 walls and a pan that snap together) actually look okay. Gut it, put in new plywood subfloor, cement board if you will be putting ceramic floor, cement board with proper flashing around shower walls, greenboard on other walls, and build it back out with a fresh interior. It'll cost more, but you'll never have to mess with it again. I take it there is another bathroom in the house? aem sends... |

Floor got wet and rotted in front of shower
Question that popped up on reading this: suppose you were to gut this
(or a similar) water-damaged bathroom to the floor joists and wall studs where water damage was fairly heavy in one corner and along a wall. Aren't some wall studs and the plate they are nailed to going to be sitting upon soaked-through underlayment and subfloor? Do you dig that out and attempt to wedge in new materials? |

The rot ends right under the 2X4 to the left and 2-3 inches under the
front of the shower. This occured due to water pooling because of tile broken and splash guard lifted up on one side. There is no plywood under the shower. It sits on a wood frame that is undamaged. I removed and am replacing the insulation and have treated/treating only slightly damaged material (wet spot on a solid 2X4). My biggest problem is the fact that the plywood goes under the wall and comes out in a hallway. The floor is fine in the hallway (to the left of the hole), but the plywood needs replacing under the wall. There doesn't appear to be any damage to any of the beams underneath the floor besides the one wet spot that is recent. (A couple of days old and I have stablized and will also epoxy). I definitely need to go get a reciprocating (sp?) saw. Thanks! (Will reply to others as soon as I have had a nap, been working on this all night...) Reiver |

Floor got wet and rotted in front of shower
The house is only 8 years old. They used pressboard instead of regular
plywood with the thin sandwiched stuff on top...then linoleum. I want to put in better wood in front of the shower, but I'm concerned about the wall to the left because that pressboard that I cut a hole in extends under the wall (2X4 where sheetrock goes) to the hallway. No damage in the hallway. Damage only extends to beneath that 2X4. Full overhaul of bathroom is a no-no, due to wife starting a new business and sucking my paycheck to next to nothing. I plan on putting roofing tarp on top of the new plywood and water protecting the area before I put the new sandwiched board on top. I am primarily interested in just repairing the area for now. Right behind the shower is another bathroom, so no we don't smell too bad...lol. Sorry if this doesn't make sense, as I'm currently sleep deprived... ;-) |

The shower is sitting on a wood frame and is undamaged. The house is
only 8 years old and the shower base was untouched. The vast majority of the damage was in the left side of the area I cut out. I cut a bigger hole because I plan to replace the plywood in front of the shower (extends a few inched under the front lip of the shower) with something a bit stronger and seal it real well to keep from having to do it again. (Of course I'm going to seal the tile in the corner when I prepare it REAL well and keep a better eye on these kinds of things from now on) The underside of the fiberglass base is also reinforced with concrete and metal. It is okay except for the one corner. I can jump up and down in the shower and it's solid as can be. |

I asked about damage to the floor going under a wall because, like you,
that is a problem I'll have to face soon in a second bathroom. Mine is a long-standing toilet leak several owners back. FWIW, I'm considering the Clear Penetrating Epoxy Sealer at www.rotdoctor.com. I haven't used this stuff, but it seems like it'll do the trick. |

I would remove as much of the damage as possible and install supports for
the edge of the new wood. Unless the damage is extensive under the wall it is not necessary to remove it. Protecting the new wood from water can't hurt but the key is to keep the water in the shower and drain. Don Young wrote in message oups.com... The house is only 8 years old.

Absolutely! I will be re-sealing the shower door frame, where the tile
meets the door and around the base, plus anything that doesn't look 100%. I plan on removing the source of the problem before using the shower again. Thanks!!! Reiver |

They aren't kidding with their warnings about ventilation! The stuff is *NASTY*. It stunk up my whole house, and I applied it outside! Great company to deal with though. -- Keith |
