Thanks Dave, My floor is pretty solid. There isn't any movement that I have noticed. My house is only 4 years old. They used the typical manufactured floor joists spaced 16" apart. If the floor is solid/no deflection, do some people tile over it using ditra? I've only helped my Dad tile his floor. His was a new house being built with the 5/8 tongue and groove ply. he still put ditra down. I'm just wondering what people do in my case. Let me know if you have any other helpful tips. take care
