Inspired by nature, Novatto's carrera marble vessel will add character and charm to any bath or powder room. Honed and polished to perfection, each 17-inch vessel is beautifully unique in white with gray veining. The exterior is chiseled giving it a beautiful natural feel. Who knew there could be so much character in a stone sink! Since marble is formed by Mother Nature, each sink will vary slightly in color and veining. These sinks have a 1.75-inch drain opening and are designed for above-counter installation with standard plumbing connections. Included with the sink is Novatto's oil rubbed bronze umbrella drain (UPD-ORB), constructed of solid brass for strength and durability. For best cleaning results, apply the included Glacier Ice Sealer. Novatto strives to provide a superior product with exceptional qualities and unique innovations professionals and homeowners trust.
