The RP-BR48 48-inch tile flange is designed to create a watertight barrier between the wall and a bathtub or shower base. By preventing water from seeping behind the tile, it protects the bathroom structure from moisture and mold. Made of durable *, this replacement part maintains its sealing properties even after long-term use. Its standard 48-inch length fits most installations and can be trimmed for a precise fit. Easy to install behind the tile during construction or renovation, it extends the life of your bathroom installation while maintaining its original waterproof performance.
