The web address of the company is www.bathfitter.com (no "s"). I just had a 25 year old bath redone. These guys did a great job. Took two days for mine as much of the tile was loose. They removed all the loose stuff and rebuilt the wall prior to installation of their product. They also installed a new valve (had to tear out part of the wall but it was part of the bad wall anyway). You would not guess this is an overlayed product. In fact, even if someone told you, you would not believe it. The tub fit perfectly inside the old one...very secure, sturdy, no hollow sound.
