We added a double deck with a drainage system so that no water would penetrate through to the lower deck. Also added another deck for the hot tub.
Don't take our word for it...
John changed our 1970 master bathtub shower into a beautiful open tile shower. It has been 3 years and no leaks. He used some of the latest membrane technologies that are available that keep your shower leak proof. The tile work was fabulous and included a niche and bench . He showed up when he was supposed to and saw the project to completion.
