NEW! HYDRO-BLOK Seals for Pipes & Mixer Valves
Seal Every Opening. Stop Every Leak.
Take your waterproofing to the next level with the NEW HYDRO-BLOK Shower Seals — designed to fully waterproof around shower heads, mixer valves, and tub spouts without the need for messy sealant.
Simple. Smart. Watertight.
Each seal is built from a premium waterproofing membrane combined with over-molded, stretchable rubber gaskets that flex and conform tightly around pipes and valves.
Just apply a thin layer of thinset before tiling, and you’ll achieve a flawless, watertight seal in minutes.
