Most showers will use a panel for each wall. Each wall panel is a separate piece. The side panels have two finished edges, (top & front,) and the back panel will have a finished top edge. Any cutting, notching, drilling, or sanding can be done using regular wood cutting tools.

Panels are attached to the wall using our adhesive silicone. Color match silicone is used to seal the seams where two onyx pieces come together. Panels can be ordered oversized and can be trimmed to fit using regular wood cutting tools. Corner trim is also available to cover gaps caused by crooked or uneven walls.

Onyx wall panels can also be used for bathtub walls. Shower Accessories – caddies, seats, and trim are available to match the Onyx shower wall panels and base.

Onyx panels are easy to clean. A common household surface cleaner that we often recommend is just diluted white vinegar. This works well on all Onyx products. Gel-Gloss will help maintain the appearance and make cleaning easier.

Graphic Inlays are also available. See pictures inlay gallery for examples.
Onyx Inlay stripes and borders are available as well. Onyx Inlays can be any color and up to 4″ on borders.
