Few Questions before i start tiling my bathroom

I am putting up tile around my bathroom. It is painted but from what i have read if i ruff it up i can put the tile right over without an issue. I was wondering if there is any problem with putting Kerdi over the painted wall around the tub/shower. Also i was wondering if there is a standard high that one puts tile aorund your bathroom walls. I was figuring 4ft would be good but if there is a "standard" there i will use it. Also i would like to use 12x12 tile on the floor and 3x6 on the wall. if i do that do i have to have a cove base or can i just butt the wall tiles to the floor with just a joint between them. Thx so much for your time.

Hi Patrick, Welcome!

If you have painted backerboard you can rough up the paint and tile directly to it if you are not using Kerdi (Make sure there is some sort of vapor barrier behind the wall). I'm not sure about using Kerdi on painted walls, someone else will have to weigh in on that, I've only used it on new, unfinished drywall.

Wainscot tile is, more often than not, about 4 ft. high. This is a personal choice in your own home, however. It can be any height, usually 3 to 4 ft. It depends on what looks best in your bath, though. Don't forget to account for the light switches, outlets, etc. The tiles can sit right to the floor tile with about a 1/8" space for expansion, etc. that you will either grout or caulk.

awsome thx so much for the advice, i will ruff up the painted drywall up to the 4 ft for the tile around the room, you have reminded me about the vapor barrier which is not there cuz i am moving the location of the tub. If i Kerdi the walls and detra the floors sealing the whole floor and walls around the tub do i still need a vapor barrier behind the drywall around the tub. if so is it the whole tub or just the wall with the pipes in it? also, should i worry about the ceiling above the tub or can i leave the existing drywall ceiling in without issue. Thx so much for your time.

If you Kerdi, DO NOT use a vapor-barrier. That will create a "moisture sandwich".
If you are going to tile the ceiling you just need to make sure it will support the weight. If your not tiling it, nothing to worry about.

ok, just wanted to run something by you guys. Im going to detra under the tub aswell and kerdi the walls all the way down to seal everything up. So that means my ruff framing for the walls at the end of the tub has to include the 5/8 board + an allowance for the kerdi to get my 5ft for the tub. I have not used the kerdi b4 so i have always ruff framed to 5ft for the tub and cement boarded above the tub. Am i over looking any potential issues with boarding to the floor and sealing it all with detra and kerdi then putting the tub in over the whole mess and tiling up to the tub? Thx so much for your time
