    HYDRO-BLOK: The Smarter, Simpler Way to Waterproof Bathrooms

    At Dupont Kitchen & Bath, we proudly carry HYDRO-BLOK, an industry leader in premium waterproofing solutions for tiled showers, wet rooms, and steam spaces. Whether you're renovating a bathroom, building a curbless shower, or designing a high-end spa environment, HYDRO-BLOK offers a complete line of building panels, shower bases, niches, and benches engineered for watertight performance and effortless installation.

    Designed in Canada and built to exceed industry standards, HYDRO-BLOK's waterproofing system offers contractors and homeowners a smarter alternative to traditional mortar bed methods. With its lightweight, easy-to-handle components and proven XPS foam + waterproof membrane construction, HYDRO-BLOK systems help create tiled showers that are beautiful, fast to install, and built to last.


    Engineered for Efficiency. Certified for Peace of Mind.

    HYDRO-BLOK products feature a closed-cell XPS (extruded polystyrene) foam core, factory-laminated with a robust, waterproof cementitious coating. This combination offers an ideal substrate for tile installation while providing:

    • 100% waterproof performance

    • Excellent compressive strength and rigidity

    • Thermal insulation

    • Mold- and mildew-resistance

    Tested to meet ANSI A118.10 and A118.12 standards, HYDRO-BLOK is suitable for use in residential, commercial, and hospitality environments—including steam showers and barrier-free spaces.


    HYDRO-BLOK Systems at Dupont Kitchen & Bath

    All accessories are factory-sealed for watertightness and surface bonding compatibility.
