Homeowner/ DIY here,
got some great feedback on my transom question, hoping to get the same for a related question by you experts.
My bathroom is currently stripped to the plywood floor and studs. The bathroom with be painted walls and only tiled in the freestanding shower walls (2). And floor will be porclean tile, large format and doing wood baseboard, not tile base. The bathroom sits on a 2nd floor, above my living room below.
I don't want the risk of any kind of possible over flow and have water penatrating at the wall where it meets the floor and water coming down into the living room........i want a bathtub effect at the perimeter if you will. How do i waterproof this condition? Using cement board for floors and green board for the walls.
I looking into possible options to do this without getting into expensive methods like membrane schluter systems. Can it be done other ways?
I'm thinking it would need to be where the cement board meets the green board.....would mortor between be enough, use liquid membrane maybe, other solutions?
