I designed this copper beauty, had it built, and installed it for a customer. I fussed and fussed to get it pretty for this picture. I had a callback several days later and the scratching and patina had begun with a vengeance. You can't fight funk. If you don't like funk, copper's not for you. They love it.

If you want a sink that looks like the above, skip the copper sink. If you want a sink that is much darker (more like the color of brass than copper when it wears in), and splotchier, then consider the copper sink.

Patina on marble works for me. Patina like that in my sink does not.
