Loxcreen’s ProVa Board Pan Assembly Kit provides components required to install and waterproof a tiled shower with ProVa Board Plus tile backer. This method works for new construction or projects where existing drywall or cement board needs to be replaced. With the ProVa system, installers are able to avoid using the two-step process of waterproofing membrane over cement board/drywall and can save time with the ProVa Board Plus tile backer and kit. Kits are available in 48” x 48” and 32” x 60”.
