Bathroom Ceramic Tile Replacement - Old House
Recently my daughter and I undertook to replace the bathroom creamic tilein her older home. The house was built in the 1920s. After removing the old tile (two layers), we found concrete poured over the floor joists about an inch thick. This layer of concrete has a few cracks but worst of all there doesn't appear to be any way to screw the next layer of cement board in constructing the new ceramic tile floor. My question is: Should we remove the concrete base and install plywood over the joists to give a solid base to screw the new cement board to?
