The Redondeado 50/50 farmhouse sink is hand hammered from 100% recycled copper by our master artisans. Through years of skill and experience passed down from previous generations, the end result is a one-of-a-kind work of art. Made from 16-gauge copper, this luxurious large sink has a curved front apron and a warm antique finish. Two spacious 14" x 18" interiors make washing any dishes a breeze. Standard 3.5-inch drain openings for U.S. plumbing connections. Due to the handcrafted nature of this product, it will vary in appearance, finish, texture, hammering and other details. Dimensions may vary up to 1/2". We strongly suggest you receive the actual piece before making any installation cuts.Copper is amazingly easy to maintain. Fingerprints do not show as they will on stainless steel and other metals. For basic cleaning simply use a mild soap and water. Other cleaners are not necessary. Copper has a "living finish" and its patina will continue to develop character over time, meaning it will become a richer, darker color. The patina creates a unique look of light and dark tones complementing each other. Made with the highest standards of quality and creative design, Novatto sinks add artful function and charm to any kitchen.
