We have a 32" X 60" shower stall in our 1981 build Florida home. There have been a couple issues with a leak below the valve and some leaks in the tile edges so time has come to rebuild this beast. Started tearing the tile off the walls and planning on taking out all the wall tile and the sheet rock on the walls and replacing with cement board and new tile. The tile on the floor is, well, 1" square off white ugly tile. It's not cracked or chipped, just ugly.
So the question is, can we tile new floor tile directly over the existing floor tile without tearing up the existing floor tile? We feel that if we tear the floor tile up we're going to be facing the major job of completely rebuilding the floor base, sloped and everything. The current shower floor is already several inches below the room floor so there wouldn't be any issue with the floor being above the room floor or anything like that. We're going to have to rebuild the ledge as it was concrete or something and the tile on it was concreted directly to it (tearing the ledge tile up is tearing up the ledge).
Any hints or suggestions would be GREATLY appreciated.
Thanks in advance.
