With nature as both guide and inspiration, Novatto carefully selects the finest Cararra marble for stone artisans to handcraft into these elegant vessel basins. Honed and polished to perfection, each 17-inch round vessel is beautifully unique in tones of white with grey veining. Because the marble is from Mother Nature, each sink will vary slightly in color and veining. These sinks are constructed for above-counter installation with standard U.S. plumbing connections. Made with the highest standards of quality and creative design, Novatto sinks add art and function to any bath or powder room. These sinks weigh roughly 25 pounds. 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 professionals and homeowners trust.
