I completely remodeled my home and all that is left is to complete a master bedroom bath, which has a jacuzzi tub with a 36" by 36" shower next to it which will be tiled, floor and all. I have done many bathroom tile jobs, but have never done a shower stall floor. I haven't found much help or info on the subject. The room is new construction, with just studs and subfloor. Any help?
