I recently inherited a small addition project from an aweful contractor (we’ve had to redo most of the work he did already.)
The addition includes a small bethroom that has a shower stall and seperate bathtub. He had framed and drywalled the rough-in for the tub before he intalled the actual tub, I guess he didn’t plan on actually tiling at all. After discussing it iwth the homeowners we deided to tile around the tub about 16 inches above the rim.
I’m having trouble figuring out how to make the surround moisture proof. I thought about putting a membrane over the drywall and then putting 1/4″ hardibacker over it, I’m just not sure about leaving the drywall there. I also considered taking the drywall out, installing a membrane and hanging 1/2 backer over top and tiling. The only problem with that is it will leave a gap that I don’t think the tile could cover, the tub has about a quarter inch gap between it and the drywall.
The best thing I think to do is pull the tub and the drywall and start over, but I don’t want to break it to the homeowners, ($4,000 in fixes already.) I wouldn’t worry about it so much but I keep hearing about mold litgation and it doesn’t sound like something I want to tangle with. Any ideas?
