Self-Supporting Corner Shower Bench The Better Bench® BB-30 Triangular Shower Bench is a self-supporting corner shower bench designed for tiled shower installations. It mounts directly to approved wall substrates and is filled with mortar before being tiled to create a permanent shower seat that blends with the surrounding tile installation. Designed for Tile and Stone Finishes Once installed and filled with mortar, the BB-30 is ready to receive tile, natural stone, glass, or mosaic finishes. Its triangular design maximizes corner space while creating a clean, built-in appearance without requiring additional framing. Durable Construction for Long-Term Performance Constructed from corrosion-resistant materials, the BB-30 supports up to 400 lbs when properly installed. The bench includes installation fasteners and is compatible with any U.B.C.-approved substrate, making it suitable for a wide range of residential and commercial shower applications.
