Maximum tile size for a shower floor?
I'm putting in a new bathroom that will have a 32" X 60" shower stall. We're intending to tile the floor and the walls up to the ceiling. The floor of the shower will be a mud bed, and I know that the slope means that huge size tiles are not a great choice, but I do want to make them as big as possible. So my question is: When shopping for porcelain or natural stone tile, what is the largest size tile I should consider for the shower floor so that the tile setter is able to do a good job working with the slope?
