This sink is light weight and high on style. It's perfect to drop in the countertop. This sink is very dark and will stay that way as long as you don't use anything stronger than soap. If you use something like Barkeeper's Friend, you can get the bright bronze color. HOWEVER, that will break through the protection of the tarnished patina and return it to a "living" metal. It will go through the cycle of being bright and shiny when it's polished and tarnishing as it is used. Some people, like me, like this, so I was happy to find it.. Amy. Madison, WI. Tue Mar 04 2025
