First, You don't Tile over Drywall in any case in Bathroom area exposed to Moisture etc.( you may have to remove existing drywall& install cement board, around that area for better results of tiling. Second. The drywall should not be, less then Blue Board for all areas except Shower or bathtub tiling.
There are two main techniques used to dry tiles. 1  Place each tile between two pieces of drywall (also called sheetrock.) This is the stuff used to build walls. You can sandwich many tiles between layers of sheetrock and stack them up. 2  Place the tiles on a wire rack to dry. This allows good air circulation.
