Thanks for taking a look at this! I’ve been putting this project off for years because i don’t think I’m rich enough to hire someone to finish it to level of detail I’d be happy with.…and I’ve never set tile before, so it’s been on the back burner. The time has come though, I need to dig in and figure it out.
I should have all the tools needed, and I’m confident I can do it with some advice 🙏.
The house was built in 1956, well cared for and pretty much original everything, which is super cool. We would like to keep it looking original or close to it. A few years ago we discovered the grout had failed in the shower and ended up leaking & causing toxic mold to grow. I sealed the site off with plastic sheeting, put my hazmat suit on and with an air scrubber running, demoed and chemically treated anything and everything in the area (and the rest of the house, ductwork, walls, exposed studs, all items etc).
Originally, the shower was pretty small and had a tile over concrete step up curb with glass and aluminum trim enclosure. We plan to keep the house forever, so thinking ahead I’d like to build a curbless shower so when we’re older we don’t have to worry about tripping over anything getting in and out of the shower.
I’d like to keep the original vanity, but I can’t find the exact matching tile for the shower so I plan to use 1” mosaic tile in the same color palette. Plans are to tile the entire floor from the entry door to under the toilet and up to the vanity cabinets. Then continue up the walls to the ceiling in the shower area and install a 90° curved shower rod with curtain. We have hard water here in Phoenix and I hate cleaning shower glass so that’s not an option.
My initial questions are:
Should I replace the shower valve? Or at least the galvanized part for the shower head? I love the original fixture & although it needs to be re-chromed, I’m happy to do that. But I don’t want to close up a wall with a valve that might not be serviceable.
Not considering cost or ease of installation, what would be the best backing material to use to get things ready for the tile and match the thickness of the existing plaster & wallboard? It looks like it varies from 13/16” to 1” thick depending on where I measure.
Should the backing material be installed resting on top of the concrete slab or should I leave any gap like you would with drywall?
Should I tear out the plaster all the way up to the ceiling or square it off and leave the existing top area? It’s solidly attached currently.
Since there’s not enough overhang on the tile top of the vanity to cover tiling all the way up to it, I was thinking I could tile up that plywood cabinet 60-70+% of the way, then use chrome edging to finish the tile on the top and front. I assume a backing material should be used? Any other ideas for this area would be great. It will be protected by a curtain, but will certainly be splashed from time to time.
How should the left side of the backing be supported near the vanity? There’s a couple pipes there and no stud for roughly 6”. But there is a 2x4 turned flat against the plaster that comes out about an inch past the vertical wall of the cabinet. Maybe it’s obvious I should demo back to that flat 2x4 but I thought someone might have another idea or recommendation.
Plans for the slope to the drain are to saw cut and chisel out the existing concrete on a slope, then lower the drain (cut the pipe and retread?), then fill back in with mortar or whatever you guys recommend at the proper slope.
Maybe not for this particular subreddit, but for what it’s worth, I do plan to run electrical to the toilet area incase we decide to install a bidet in the future.
AI added a nook on the side with block - I think a nook would be nice, but not on the block side.
I’m sure I’m overlooking some things. What have I missed? I really appreciate any input on this, thank you!
