Water seeped through tiles in shower, wall ruined, need help.


Ok Doogie88, we've got to get some terminology right. The vertical 2x4's in your walls are called studs. Beams are horizontal and support your floor, roof, and ceiling. When we refer to studs, you gotta know what we mean! Not trying to pick on you. (well, maybe a little)

Okay, I have some pictures. I took all the wall down in the shower.
But, I don't know how far to go? To the next beam?
The existing sheetrock should get cut back to a stud or a corner. You never, never, never should have vertical seams of sheetrock or backerboard (or both) that don't securely fasten to a stud. It is common to need to install additional pieces of 2x4 against an existing stud to facilitate good attachment of new rock or backer without disturbing the old stuff too much. Use deck screws to secure the new stud material to the old. It doesn't have to be as tall as the wall, just enough to allow you to put a screw every 8" or so along the seam.

1) The sheetrock beside the tub turned out to be wet and mushy, as well as much more of it, as you will see. Should I cut out right to the next beam, which I guess would be a couple feet? And put the moisture resistant sheetrock from that beam to the one at the shower? then put the concrete board for the rest? The boards you see beside the beams now, are not very sturdy.
Can't see the picture, but you may need to add a stud or two as described above to make the backerboard/sheetrock seam occur right at the edge of the tile. Very important.

2) My floor is ruined, wet from a week ago, and warped/bubbling, do I need to replace my whole floor (floorboard?)? My bathroom IS pretty small. 8' x 5' I believe. Or could I just cut out 2 1/2' and put a sheet of concrete board there?
Need to see the picture. What are your plans for the floor? Tile? You must have plywood under the tile, and backerboard is recommended as well. You can use 1/4" backerboard and 3/4" plywood if thickness is an issue. The floor's backerboard should be set on the plywood in a grooved/troweled layer of thinset, then screwed down with a screw every 6-8" in a grid pattern.

3) What do I used to cut the wall straight and level so I can match up the new moisture resistant sheetrock with it? Drywall saw?
Utility knife and a straight edge. Lots of elbow grease and a couple extra sharp blades.

4) The plastic covering the insulation now has some holes in it form all the screws. Are those important? Do I need to patch them up or replastic? Or the face that I will have sealed concrete board be ok?
Sealing the concrete board will take care of it. I wouldn't sweat the holes.

Thank you so much!

Thanks again, I am actually enjoying this.
Oops, forget the pictures.
Here they are to get a better understanding.
Basically the next STUD is going to be behind my toilet, but I'm going to get a new toilet, so it shouldn't be too hard to work with.
I'm mid 20s and work on the computer 12 hours a day, so thanks for the terminology.

An added stud (or two fastened together) would work great behind the toilet, or wherever you choose to splice the rock.

Here's a crude diagram showing how to handle the vertical seams you'll encounter. We'll cover mudding and taping sheetrock joints later when you come to that.

Thanks. I will do that.
How come the bevel though? And do I have to do it the the old sheetrock too?
Do I put drywall tape over it?


Also, for my floor, should I replace the whole floor? Minus the tub, it's about 5' x 5 1/2'.
I'm actually going to be replacing the vanity, my current one goes right to the floor, the new one does not, so the anolium(sp?) will be coming out no matter what.

The bevel is only about 1/4", and helps hide the seam, which is tough for a rookie, but can be done with some practice. Without the bevel, the rough square edges of your cuts will telegraph through the seam. Yes, you'll mud and tape the seam. I'd wait to do that until you're done hanging backerboard. Fill the joint with drywall mud, then lay in the paper drywall tape (don't use mesh for this joint), bed it in the mud, and let it dry. It will take 3 or 4 applications of mud and subsequent light sanding to get the joint feathered out. It'll be about 12" wide when you're done. Otherwise it will show. We can cover this in depth later if needed.

Also, for my floor, should I replace the whole floor? Minus the tub, it's about 5' x 5 1/2'.

Tear out the linoleum and determine the condition of the plywood. Also make sure it is 3/4" thick. If it is soft, spongy, de-laminated, or otherwise messed up, replace it. Screw it down like crazy whether you replace it or not.

On a recent bathroom remodel in my house, I had to add a lot of wood studs and blocking to facilitate attachment of backerboard and rock, as well as replace sections of water-damaged studs.

Thank you very much. Sorry for all the questions, I just want to make sure I do it right.
One last question (I hope!), how should I handle this (pic attached) with the backerboard.
I mean the stud is already about 4" in from the end of the tub. And since there was water there, I'm kinda worried about using the water resistant sheetrock along the side of the tub. Or do you think it will be okay as long as I caulk it properly?

I think your concern of using sheetrock against the tub is justified. If you can wrap perhaps a 4" tile around the edge of the tub with backerboard underneath it, that would be ideal. If there will be a shower door I'd be less concerned, but if there's only going to be a shower curtain, water would inevitably get down there. If you're willing to use tile, that's the way I'd go.

Just add a couple studs to the one that's there. That way you can fasten your sheetrock.

Okay, one more question.
How important is it to replace the plumbing? The house about 20 years old.
It just seems a bit expensive for the part, and a lot more work on top of what I already have to do.
And replace plumbing, you mean pretty much everything?

Okay, I got my stuff. RedGuard was $80, didn't think it was that much. Guys at HD didn't even know what it was. Luckily they thought they knew something like it, and sent me towards the kitchen/bath, and I found it there.

Be sure to tape and thinset those backerboard seams and let them dry before applying the RedGuard. Yup, its $80, but that's cheap insurance against leaks!

Okay, here are some pictures of my floor.
It seems the top layer is particle board(?), I think 1/2" thick. Then there seems to be another type of board below it, a more solid board. The board below is wet, but doesn't fall apart as easy.
I'm not too sure what to do here?

You see the water marks go pretty far, do I have to replace that far?
Should I just take off this top 1/2" board, and replace it with 1/2" cement board? The guy at HD said not to use cement board because it was heavy. He said to fix the problem first and use what was there. :/

Do I have to buy some type of electric saw for this? Or borrow or anything?
