Skyland Building

Was having a totally new bathroom done gutting and all. Completed 90% of work but has major screw ups as well. Grout in shower color is uneven big time. He blames the water in town. If true how come grout on floor (different color) is ok. Grout in other parts of house ok. Big mirror is cracked. It has happened twice. Keep in mind bathroom job included taking all walls down. He is now blaming the"curvature" of the wall. Although I had a bathroom mirror there before. He recently told me he is no longer doing residential work. That's it. Approx $40,000 bathroom that's unfinished. The only reason I gave it a 1 is that he brings a cute dog with him. (Being sarcastic)
