Second Floor Concrete Subfloor
#1

I am in the process of remodeling my bathroom, which was remodeled in the 60's. When I go to take out the floor, I find the floor is made up the same way the walls were made up of. They used chicken wire with concrete on the floor and then tiled over it. I am replacing the floor. What would be the best way to replace it? Should I tear up all the concrete and then lay plywood, moister barrier and then backerboard? I am not sure how to approach this? Any help will be appreciated.

Rip it all out then go with the plywood and cement board. If a waterproof membrane is required you could use Ditra in place of having the cement board, not sure if one is really needed unless you plan to flood the floor a lot
