Conflicting Floor Methods
Was looking for some direction on our bathroom floor. In the interest of saving costs, I decided on doing most of the work with the exception of the actual tile work. I gutted the room, redid the plumbing, installed the bathtub, installed poly sheeting with Durarock cement board. The floor had 1/2 plywood, which I added another layer of 5/8" plywood.
I wanted to install a suntouch heating mat. I was getting estimates on the bathroom and had several methods the contractors mentioned. None were consistent. Any advice what sounds correct?
A) Laydown the electric mat, pour self leveling concrete on top. Tile.
B) Prime the floor, laydown the mat along with a plastic mesh on top, pour self leveling concrete on top. Tile.
C) Install 1/4 Hardi Backer board, laydown the mat, pour self leveling concrete. Tile.
D) Ditra mat he was going to use. But he was not sure where the mat needed to go (above/below)?
