Onyx

Onyx is manufactured of alumina tri-hydrate crystals and resin. It is protected with a clear stain resistant resin topcoat. Features include integrated under-mount sinks, coved backsplashes, and many custom inlay options. Onyx is a good product for vanity tops as well as other bathroom surfaces including showers and tub decks. However, it cannot be used for kitchen tops due to fabrication issues.
