I have a early 70's home with a small bath with tub, also a half bath with shower, they back up to each other and the water connections are in the same wall. I have some problems with the shower leaking and when I tore out the dry wall and tile in the main bath i discovered the bottom plate on the framing for the shower is rotten, the studs are ok. Im trying to keep a bath and toilet open so Im gonna tear out the shower now and leave the toilet in the half bath for a while till I can get the main bath up to par.
I've got a few qestions so Im just gonna list them and appreciate any advice anyone cares to offer.
1-The shower appears to be mud over metal lathe and the same for a shower pan, no backer board. I would assume its better to just tear the whole mess out and go back with a properly built up pan and concrete backer board. Im going to shore up the framing and cut enough off the bottom of the studs to slide in a double plate. (trying not to tear everything out as it would involve sides on a double closet, bedroom and main bath) Do you thing that I should used pressure treated for the plates. Its a small shower about 30"x30". Ive considered a fiberglass replacement rather than tile but would have tear a wall out to get it in. Also once I button this up I dont access to the water as its on both sides of the wall in two different rooms. Suggestion?
2-When I tore out the tile and drywall in the main bath, the outside wall did not have any vapor barrior, just drywall and fiberglass batts. Do i need to put up a plastic vapor barrier when I hang the sheerock ?
3-I tore up the tile on the floor ( house is on a slab ) and chiseled up about a one inch mortar bed( was that ever fun ) .There was no bed or tile under tha vanity, would it be better to do the whole floor and then set the vanity or is it not done that way.
4-Under the tile surround on the tub, there was sheetrock and backer board over that, should that go back that way, or just used the backer board there, this house is over 30 years old so dont know if something new works better now.
5-Im going to start tearing the shower out tomorrow and can hit it from the back through the studs on two walls, im assuming thats the easiest way, and guess ill rent an impact demolition hammer to get the pan and curb out, unless you guys have any suggestion.
I want to put everyhthing back the right way and would appreciate any info and suggestions you folks might care to share. Im pretty handy with tools and have a pretty nice shop but just dont do this kind of work very much. I work with my hands a lot but not on this scale.
Sorry for the extended post but thought i would just put it all down at one time.
