Welcome to the world of Prova!

The ultimate waterproofing system features all of the components required to build a fully bonded water tight assembly for maintenance-free tiled showers. Our line of PROVA® products protect floor, wall and ceiling cavities against water and vapor penetration and prevent mold and mildew build-up over years of use. The pre-fabricated sloped pan for shower bases eliminates the need for a mortar bed and reduces the overall weight and installation time.

Step into an unfinished bathroom with PROVA® and watch how this revolutionary line of products transforms the installation process. The design possibilities are limited only by the imagination!
