Squeegee the walls after every use, clean weekly with a pH-neutral cleaner, and never with an acidic descaler. Soap scum is alkaline and comes off with a stone-safe alkaline cleaner; acid etching is what a descaler does.
Order the wall in panels and the floor honed, and specify the wet-area system with whoever is building the tank. In a shower the substrate and the waterproofing are decided together with the stone, not after it.
Yes, and it is one of the better uses for it, provided the surface is honed rather than polished and the wet area is built as a wet area. The stone is at its best where it is large, flat and vertical.
With a honed finish and the falls set before the stone is measured, yes. It is the surface people ask about for this stone, and it is a good answer — but the stone is not what decides it. The fall, the drain and the tank are.
Yes, as a slab shower lining rather than as tile, and the substrate has to be a wet-area system with a real fall. On a straight figure the wall of a shower is the surface this stone is at its best on, because it is large and vertical and it is seen close.
Yes, and it is a good answer for a hotel bathroom, provided the surface is honed and the wet area is built as one. A hotel bathroom is cleaned several times a day with a controlled product, which is exactly the condition a sealed calcitic stone wants.
