Inspired by nature, Novatto's white Carrara marble vessel will add character and charm to any bath or powder room. These natural marble sinks come from around the world to become your one-of-a-kind bath centerpiece. Natural stone cannot be compared to everyday synthetic porcelain and ceramics. Honed and hand polished to perfection, each stone vessel sink is beautifully unique in tones of white and grey. The high sides are 6 inches tall while the center dips down to 4 inches. While they are consistent from piece to piece, each sink will vary slightly in color and veining. These sinks are designed for above-counter installation. They have a 1.75-inch drain opening for standard U.S. plumbing connections. For best cleaning results apply the included Glacier Ice to help protect the surface and allow for easier cleaning. Included with the sink is Novatto's umbrella drain (UPD-BN), constructed of solid brass for strength and durability. Finished in brushed nickel, the drain assembly has two rubber seals, a plastic spacer, and brass fastener. Novatto strives to provide a superior product with exceptional qualities and unique innovations professionals and homeowners trust.
