Made with nature as both guide and inspiration, Novatto's coffee marble vessels will add character and charm to your bath. Our marble sinks come from around the world, giving you a one-of-a-kind bath masterpiece. Natural stone cannot be compared to everyday synthetic porcelain and ceramics. Honed and hand polished to perfection, each 17-inch round vessel sink is beautifully unique in tones of brown with white veining. Because marble is from Mother Nature, 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. Suggested Novatto umbrella drains: UPD-MB (matte black), UPD-ORB (oil rubbed bronze), UPD-BN (brushed nickel), and UPD-CH (chrome). For best cleaning results, a soft cloth with mild soap and water or a non-abrasive stone cleaner is recommended. A stone sealant like Glacier Ice should be used to help protect the surface and allow for easier cleaning. Novatto strives to provide a superior product with exceptional qualities and unique innovations that professionals and homeowners trust.
