Compotite Shower Pan was founded in Los Angeles in 1938 to manufacture and market “Compotite”, a patented material developed by G.A. Morthland as a waterproofing substitute for lead shower pans in homes. In 1958, the company was incorporated and soon Compotite was included in all model plumbing codes and sold nationwide to waterproof shower floors under a thick-bed mortar setting of ceramic tile or marble.
