The Andulusia is a unique vessel constructed from recycled copper by our master artisans in Mexico. Through years of experience passed down from previous generations, the end result is a one-of-a-kind masterpiece. Made from extra thick 14- gauge copper, the Andulusia has a beautiful natural finish. Copper has a soft luxurious look and is amazingly easy to maintain. Fingerprints do not show as they will on stainless steel and other metals. For basic cleaning, simply use soap and water. Copper has a "living finish" and its patina will continue to develop character over time, meaning it will usually become a richer, darker color. The patina creates a unique look of complimenting dark tones. Made with the highest standards of quality and creative design, Novatto sinks add art and function to any bath or powder room. Standard 1.5 inch drain opening for U.S. plumbing connections.
