Kohler Hartland is junk, I got it and set it on new cabinets, mounted Corian counter top over it and installed new Kohler faucet , as soon as water hit the sink it started popping/chipping pieces of enamel. As I am writing this my Wife just set another chip on the counter next to me that popped as she was running water in the sink. I called Wayfair and they would not warranty it because it was ordered over 30 days ago. They gave me a phone number and info so I could attempt to warranty sink with the warehouse they get Kohler product from, so far not so good. Even if I can get a sink replacement, remove and replace of sink is on me, and it's going to be expensive. see attached pics of chips

Would have been a nice sink if it wasn’t cracked when received. Returned it!

This sink in ice gray is GORGEOUS. I love it, can't say enough. Thank you WAYFAIR.

The Kohler cast iron Under mount kitchen sink was a great choice and it arrived on time and in perfect condition.

Item arrived safely, delivery secured as instructed with respect to the property.
