Very professional and knowledgeable. They did exactly what they said they would do and there were no surprises during the process. Our installer, Rob, was alway on time and very clean and neat. I got an update everyday. I would highly recommend Rebath of Tyler for your next bathroom remodel.

We had a tree fall and knock down our power coming into the house. I contacted Clay Cooper and he was out the next day. He ended up running it underground and installed a new 200 amp service. Excellent work and would highly recommend!
