Product Overview

The Full Foam Shower Curb is a prefabricated, waterproof, tile-ready shower curb designed for seamless integration with shower systems, including foam shower bases or conventional mortar bed installations.

Manufactured from high-density XPS foam with fiberglass mesh reinforcement and a cementitious coating, this curb provides excellent load-bearing performance while remaining lightweight and easy to install. Its pre-sloped design directs water back toward the shower drain, ensuring reliable water containment and long-term durability in wet areas.


Key Features & Benefits

  • Tile-Ready Surface Cementitious outer coating allows direct tile installation using standard thin-set mortar—no additional prep required.
  • Pre-Sloped Design Slight inward slope directs water back into the shower, reducing splash-out and leaks.
  • Lightweight Yet Load-Bearing Rated up to 280 lbs/ft once tiled, suitable for glass doors, panels, or blocks.
