We are in desparate need of a new sub-floor and floor and tile for our powder room. The plumber came and removed the toilet to inspect why the floor tiles were buckling. There was water damage. The toilet is up and we needed an expert to come and put in a whole new floor and tile. Is there any one out there that can do this or recommend a good person to do a small job like this. Area is approx 18 sq ft.
