4' x 40' Grey PVC Shower Pan Liner

Product Overview  

Durable yet flexible, The Bluefin Shower Pan Liner is a 40-mil PVC waterproofing membrane designed for high-moisture environments. Its pliable enough to install faster than rigid metal liners, but tough enough to resist punctures from tools or mortar beds. Even after long-term moisture exposure, this pan liner delivers the durability and compliance professionals expect.
