Sierra Copper makes this sink

What is the cost of the sink?

Where can I get the sink? Is dark copper hard to maintain?

Hi debnt,

If you choose copper, you'll find it is amazingly easy to maintain! Hammered copper is particularly simple since it doesn't show fingerprints as stainless steel or shiny copper does. For basic cleaning simply use a mild soap and warm water. Keep your copper product clean and dry by wiping it down after each use with a soft cloth. Harsh abrasives or copper cleaners should never be used on our products as they may affect the finish. For extra protection, a product such as Flitz Faucet Wax+ may be applied.

But don't just take our word for it! Check out this previous houzz discussion, which may answer some of your questions.
