The Cordoba Rolled oval sink is hand-hammered from 100% recycled copper by 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 18 gauge copper, the beautiful Cordoba Rolled has a warm antique finish and a rolled rim allowing for a seamless drop-in installation. Due to the handcrafted nature of this product, it will vary in appearance, finish, texture, hammering and other details. Dimensions may vary up to 1/4". We strongly suggest you receive the actual piece before making any installation cuts. Included with the sink is Novatto's 19 hole strainer drain (STD-ORB), constructed of solid brass for strength and durability. Finished in oil rubbed bronze, the drain assembly has two rubber seals, a plastic spacer, and brass fastener. 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 bath or powder room. Supreme packaging and boxing ensure damage-free delivery.
