Shower liners are all one piece with no seams ensuring there are no points of failure. Our competitors pans have seams. Unlike our competitors, we double coat every fiberglass project and use Gel-Coat to waterproof and weatherize. Raw fiberglass that hasn't been Gel-Coated will deteriorate over time. The Gel-Coat is the same product you would use to finish any professional fiberglass project, from boats to cars to shower pans to decks, once applied it forms a water and weather tight finish that will never deteriorate. Our process is done the correct way every time and we guarantee our pans will ALWAYS hold water during testing and will ALWAYS pass inspections. With over 20+ years of experience, we will make sure you can test, pass and get on to the next phase of construction without worry. We are prompt and maintain a 24-48 hour lead time so when you need us we will be available and ready to start.
