Onyx Collection Showers are a man-made material that has a lifetime warranty.

The Onyx Collection products are made from a combination of alumina trihydrate crystals and a special polyester resin they have developed over 25 years. The result is a product that is extremely durable and easy to maintain and clean. Undoubtedly, the Onyx Collection products are built to last.

The Onyx Collection offers an extensive selection of shower components (like shower bases/ shower pans, shower surrounds), bath components (like wall kits and surrounds), bath and shower accessories, and lavatories in standard sizes. But they also offer custom products. The Onyx Collection can accommodate virtually any request for custom sizes, shapes, special angles, special drain locations, and ADA ramp accessibility.

Onyx Collection Walls for the shower or bathtub are available in various height, color, and design. Panels come in Gloss Finish, Stone Tile, Subway Tile, Wavy Tile and Shiplap. An Onyx wall panel is approximately 5/16″ thick and is a solid color throughout. Each weighs about 3.5lbs per square foot.

Onyx walls can be used as a tile alternative to your shower walls, alcove bath walls or tile down bathtub. 

Onyx walls for shower or bathtub are easy to clean. A common household surface cleaner that we often recommend is just diluted white vinegar. Applicable to Onyx Vanity Tops, too.
