This is a beautiful sink! Looks great in our remodel. No stains yet but if I do find any I always keep Barkeeper's Friend handy. This is a great sink. Very pleased so far!

I love this sink!! It is such a perfect size and I love all the essentials that came with it. I rated 4/5 only because it it extremely easy to stain but after trying product after product, the only thing that got the stains out was oxiclean (we soak our clothes in the sink) so I 10/10 recommended because of how easy the stains come out with that! ... show more

    • Sink broke
Style: 28 X 18 Inch Color: White
This sink is lovely, however… once installed and within two weeks of light use… it cracked/failed. We now have a cracked sink after one month and don’t have any idea what to do. Sad… Update: they did provide us with a full refund - which was a nice gesture - but this is a very awkward and difficult thing to replace in a finished kitchen 😵 ... show more

    • Sink it cracked upon arrival
Style: 28 X 18 Inch Color: White
Just got it out to install, had to order ahead of time for new countertops to be measured correctly. Sink is cracked and out of return window by two weeks. Review edited, seller refunded cost of sink, I also purchased a new one because my.counters were laser cut to fit this exact sink.

Beautiful sink, when I have put pots in it it gets scratched but I rub off the scratches right away with soap and water and it comes off as of now.
