We are putting in a new bathroom sink, tub, and toilet. The present wall situation is tiled all the way around the whole bathroom, only half way up the wall. The tiles have come off and I found that the wall is half stucco and half plaster. What is the best thing to do about putting up a new wall and tiling just the bath tub area? I was told because the plater and stucco are uneven as far as the surface is concerned it would be best to rip out the entire wall.. and put up green board and cement board... is this true???? Please e-mail me back.
