Lightweight Shower Curb for Tile Shower Systems The GoBoard® Shower Curb is a lightweight, waterproof component designed to create the curb section of a tiled shower pan. Its block-shaped profile provides a ready-to-tile base that integrates with the GoBoard Shower Pan System for residential and commercial shower installations. Easy On-Site Sizing and Installation Manufactured from high-density closed-cell polyiso, the curb can be trimmed with a standard utility knife to accommodate custom shower layouts. Multiple curbs can also be installed side by side for wider shower openings without adding significant weight. Designed for Complete GoBoard Shower Systems The GoBoard Shower Curb is engineered to work with GoBoard fasteners, washers, sealant, and shower pan components. When all joints and fastener penetrations are properly sealed, it provides a waterproof foundation ready for tile installation.
