We are budgeting a bath renovation for a client. The demolition has been done and part of the scope involves converting the bath tub to s shower.
The clients are looking at doing the walls in 2 cm slab (probably Statuary White) marble, with an accent of tile inset horizontally which will continue through the remainder of room, outside the shower. This means that there will be a seam/ joint in the middle of the wall.
The exisitng walls are tile (which we have removed) over the plaster, over terra cotta and gypsusm block, which is a common material here for interior partition walls in early 20th century buildings. Removing the plaster finish from the block is likely to disturb the walls and damage the paneling in the dining room on the other side of the wall.
The question become how to waterproof the assembly, Our plan would be to cut the chloralloy liner into the existing plaster so that the plaster is proud, much like durock is proud of the liner when doing a shower in typical frame construction. We would then put a water proof membrane on top of the plaster (probably kerdi or Noble TS) and set the slab and tile on this. I am concerned about moisture coming through the stone/ tile and damaging the plaster.
The building is requiring a traditional Chloralloy pan, as they have had bad experiences with poorly done alternate receptors.
Any thougths on adhesion and potential for issues with slab on the sheet membrane? We have done lots of tile over kerdi or other membranes, but not slab.
Thanks
