It has been three years now and I have hated the sink. There’s something about the enamel that absorbs all stains. It looks terrible all the time. I’m so unhappy with it.

Finish:White

We purchased this at the end of August as part of a full kitchen remodel but it was just installed a week and a half ago. (It had been boxed up safely in the garage) I am not sure if it came this way and I just noticed but we have been very gentle/cautious as everything is new and there is already a chip after a week and a half!! I realize it is small but worry it will continue chipping and this was a very pricey sink so I feel like it should be more durable then to already have damage in such a short timeframe. I do love the look and functionality though.

Beautiful sink but arrived severely damaged. It’s extremely heavy and should have been packaged better.
