I just had a handicapped accessible tiled walk-in shower installed. The floor is concrete with a vinyl pan and 2" ceramic tiles set in grout.
Because it wasn't pitched properly it is pooling water and puddling in sections. The contractor wants to repair it by adding a new layer of properly pitched grout and new tiles over the old. Is this feasible or is it necessary to tear up the floor and install a new vinyl pan, grout and tiles?
Any advice would be appreciated.
