Wide width. Zero seams. Total water protection.

Construct a bulletproof shower base with this heavy-duty PVC Pan Liner. Engineered to meet strict ASTM D4551 plumbing codes, this membrane features a robust 40-mil (1mm) thickness that resists tears, punctures, and construction traffic. The superior 73-inch width allows for seamless coverage in standard 5-foot and 6-foot shower stalls, eliminating the need for risky solvent-welded seams. Flexible yet durable, it corners easily and creates an impermeable barrier for mud bed and tile installations.

Features
  • Seamless Coverage: The extra-wide 73-inch roll creates a continuous barrier for standard shower floors (up to 6ft), eliminating the need to glue seams and significantly reducing the risk of leaks.
  • Code Compliant: Manufactured to meet ASTM D4551 specifications, the required standard for PVC flexible waterproofing membranes in residential and commercial plumbing.
  • Heavy-Duty 40 Mil: At 1mm thick, this liner provides the puncture resistance needed to survive rough installations while remaining flexible enough to fold tightly into corners and curbs.
  • Rot Proof: Completely impermeable to water, vapour, and mildew, protecting your wood subfloor and joists from the catastrophic damage caused by shower leaks.
  • Easy Bonding: Compatible with standard PVC solvent cement (glue) for secure detailing around dam corners and drain flanges.
