Truly a work of art by Mother Nature, Novatto's petrified fossil wood vessel will add special character and charm to your bath. These come from around the world, giving you a one-of-a-kind masterpiece. Natural stone cannot be compared to everyday synthetic porcelain and ceramics. Honed and hand polished to perfection, each irregular 17-inch vessel is beautifully unique in tones of brown and tan. Although they are very consistent each sink will vary in color, shape and size. These are designed for above-counter installation with standard U.S. plumbing connections. For best cleaning results apply the included Glacier Ice sealer. Included with the sink is Novatto's umbrella drain (UPD-MB), constructed of solid brass for strength and durability. Finished in chrome, 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. Novatto's customer service is always here to answer any product questions or help you choose a matching faucet.
