When properly installed with a coat of thinset beneath it, cement backerboard won't flex like plywood, and won't contribute to problems like lippage. This makes cement backerboard a good choice for large format tile floors, as well as for older homes that may have more uneven subfloors.
Do you have to put cement board under tile?
Whenever you're laying tile on a wood subfloor, you need to first install cement backerboard to prevent leaks and water damage that could harm your flooring and the structure of your home. Unlike wood or drywall sub-surfaces, cement backerboard will not rot, warp or grow mold and mildew when exposed to water.
How thick should cement board be under tile floor?
Floors: A 1/4-inch minimum thickness is needed, but thicker panels are also fine. Walls: Use 1/2-inch or 5/8-inch-thick cement board, not 1/4-inch. The extra thickness is needed when spanning the studs and it provides a solid base for the tile.
