This ready-to-install, waterproof curb is made of a lightweight foam, manufactured with a waterproof proprietary blend of synthetic polymer mortar and an alkali resistant fiber mesh. The waterproof curb is prefabricated so you only have to ensure the corners are sealed before you tile. Designed to integrate with the Everbilt shower system, the curb is loadbearing and heavy-duty, and can be tiled upon to create a completely waterproof design. If a longer curb is required, simply combine and join multiple pieces with Everbilt seam tape and waterproof wallpaper membrane. If a shorter curb is required, simply cut this curb down with a sharp razor blade knife.. 60" prefabricated waterproof curb. Front edge of a shower. Ready-to-install. Lightweight.
