At Sierra Glass Block and Hawaii Glass Block, we’re committed to helping you realize your design dreams.

One of our most popular shower systems, Hydro-Blok is an affordable waterproof concept that is easy, quick, and user-friendly. Able to be implemented as a DIY project or through a contractor, it’s a convenient and hassle-free way to build and customize the shower of your dreams. Its closed-cell XPS foam core and polymer-modified cement coating enables a fully-waterproofed line of shower pans, wallboards, and accessories to operate in a way that enables them to be simultaneously lightweight and strong - truly the best of both worlds. Best of all, they can be customized to fit any shape or size bathroom, enabling you to create your design vision just as you’d want.
