    Default how to install marble flooring over raised foundation subfloors?

    Hi, we are remodeling in bathroom. We have raised foundation (crawl space), and wood subfloors. What is the best way to install marble flooring? Do we need cement board? And what to use: adhesive/glue or cement? Would appreciate your reply! Thanks.

    All natural stone requires a maximum floor deflection of L720. To figure that out you'll need to know your joist spacing, size, and unsupported span. Once you get those numbers, plug them into the handy dandy deflecto-lator over at the John Bridge Tile Forum and see if your joists will handle the marble.

    You'll also need a minimum of 1 1/4" of plywood under there. No Sheathing grade, no CDX, no 1/4" plywood.

    Yes Ceement board is good to adhere the tiles to. There is also Ditra and Greenskin you can use.

    What kind of marble? If green or red marble, you'll need special setting materials. If white (Carrera or Thassos) then white thinset.
