Copper Potter sinks are hand formed from the finest quality copper available today. The patinas are created by a firing process and will change over time, developing more interest and variations. A copper finish is a living finish and never really stops changing in color. Copper is more sanitary than any other sink material, it's antibacterial. Each Copper Potter product is individually "HANDMADE" and unique, therefore finish, exact sizing,etc., may vary from item to item. Farmhouse, Apron, Undermount, Vessel, and Drop-in Sinks are available.
