With nature as both guide and inspiration, Novatto's coffee marble sinks will add character and charm specific to your bath. Our marble vessel sinks 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 17-inch vessel is beautifully unique in tones of brown with white veining. Because marble is formed by Mother Nature, each sink will vary slightly in color and veining. Designed for above-counter installation, these vessels have a 1.75-inch drain opening for standard U.S. plumbing connections. Included with the sink is Novatto's chrome umbrella drain (UPD-CH), constructed of solid brass for strength and durability.For easy maintenance apply the included Glacier Ice sealer. This will help seal the pores in the stone to prevent water spotting. For best cleaning results, a soft cloth with mild soap and water or a non-abrasive stone cleaner is recommended. Novatto strives to provide superior products with exceptional qualities and unique innovations professionals and homeowners trust.
