The Navarre is a hexagon-shaped bar sink hand-hammered from 100% recycled, lead-free copper by master artisans. Through years of skill and experience passed down from previous generations, the result is a one-of-a-kind work of art. Made from ***16-gauge copper***, the beautiful Navarre has a warm antique finish and a 1-inch flat lip, allowing either drop-in or undermount installation. The sink has a 3.5 in. drain for standard U.S. plumbing connections.Included is a hand-hammered, solid copper strainer drain, both functional and stylish, adding rustic charm to your bar or prep space. Unlike plated alternatives, the basket strainer is crafted entirely of copper, hammered, and dipped in a patina solution, then hand-rubbed for rich, unique coloration. 4.375" diameter, brass locknut, 1.875" threaded tailpipe connection. NOT for use with garbage disposal.Copper is naturally easy to maintain - fingerprints won't show as they do on stainless steel, and simple soap and water are all that's needed for cleaning. Its "living finish" will continue to evolve, developing deeper tones and a rich patina that enhances its character.Combining art and function, Novatto sinks are made to the highest standards and backed by a Limited lifetime warranty. Each sink is securely packaged to ensure safe delivery. (***Note: The lower the gauge number, the thicker the copper.). Color: Hammered Antique.
