Made from one of Earth’s most precious stones, Novatto’s white onyx vessel will add special character and charm to your bath. Our onyx vessels come from around the world to provide you with a one-of-a-masterpiece. Natural stone cannot be compared to everyday synthetic porcelain and ceramics. Honed and hand polished to perfection, this round 17-inch vessel is unique in tones of off-white with gold veining. Onyx is also translucent letting light easily pass through it. If you are looking to make a statement, place lights in the counter underneath the sink to give it an ambient glow! Since onyx is from Mother Nature, each sink will vary slightly in color and veining. These sinks are designed for above-counter installation with standard U.S. plumbing connections. For best cleaning results, a soft cloth with mild soap and water or a non-abrasive glass cleaner is recommended. A stone sealant should be used to protect the surface and allow for easier cleaning. Included with the sink is Novatto’s umbrella drain (UPD-MB), constructed of solid brass for strength and durability. Finished in matte black, the drain assembly has two rubber seals, a plastic spacer, and brass fastener. Novatto strives to provide superior products with exceptional qualities and unique innovations that professionals and homeowners trust.
