The Prova Waterproofing Board Pan Assembly Kit 48" x 48" delivers a professional waterproof solution for tiled showers, offering the convenience of a prefabricated modular sloped pan system. This shower pan assembly kit includes the Prova Pan with an offset drain outlet, the Prova Mat pan liner, a drain flange with a 304 stainless steel grate, Prova Seal tubes, and Prova Fasteners — screws and washers, giving contractors, builders, and DIY homeowners all the core components needed to create a watertight tile shower base that is ready to tile, saving time and labor, during bathroom renovation projects. Designed for use alongside the Prova Board Plus tile backer (sold separately). The lightweight EPS core construction makes the shower pan durable and installer-friendly, while still being easy to cut, handle, and position directly on the floor. Approved by ICC-ES and designed for use with premium polymer-modified thinset mortar meeting ANSI A118.15, the system ensures secure bonding without the need for mastic or premixed mortar. With the Prova shower waterproofing kit, installers can build walk-in showers, bathroom remodels or tiled shower bases with reliable long-lasting performance and flood test certification for complete confidence. The integrated waterproof membrane ensures water vapor resistance and leak protection, supporting large format tile, porcelain, ceramic and stone applications. This professional-grade shower assembly streamlines workflow with a ready-to-tile solution that delivers efficient drainage and maintenance-free performance. Whether used in new construction, commercial settings, or DIY bathroom projects, the Prova waterproof system provides a cost-effective, contractor solution that enhances floor preparation, supports grout and thinset mortar adhesion, and creates a sealed, vapor-tight installation. The 48" x 48" prefabricated shower base with offset drain is easy to install and engineered for long-lasting waterproofing performance.
