5.0 out of 5 stars Finally a sink that stays clean after use!!!
By MailDump on January 21, 2015
I love this sink! We've had it for about 6 months and it still looks brand new. A vinegar cleaning then wipe it with vegetable oil is all you need to do to keep it looking great. We live in Denver so our water isn't bad though. There aren't any scratches and we clean our heavy cast iron pans in it. I don't think I'll ever go back to that ugly, spotty, scratched stainless steel again!
The first picture is after not being cleaned or oiled for about a month... maybe longer. The second picture is just after oiling it. The third picture is just to show how we used the edge to hold cutting boards, like other more expensive sinks have now added for a special feature.
It's also big enough for my son's bumbo chair to fit in it so I can still give him baths in the sink, which my back is very happy about.

5.0 out of 5 stars I LOVE this sink
By L. Hrydziuszko on December 25, 2019
I fell in love with this sink as soon as I found it on Amazon. Read the reviews and felt confident that this was a great product with a perfect price point. Was on alert for cracks when delivered, but we lucked out-- arrived in perfect condition.
It is gorgeous in person. So roomy. And it has a little sparkle in the right light, which I also love.
The only flaw we could find was the mounting equipment. This is a heavy sink, and the brackets were not up to the job. Ended up bracing it from underneath with boards.

1.0 out of 5 stars Arrived broken- super disappointed!
By Dixie_01 on August 21, 2020
Arrived broken! I paid full price for a broken item and have to use it due to installation and home renovation timing needs. I’m very disappointed in the quality of this item and the condition it arrived in. Will update review if customer service resolves the issue.

5.0 out of 5 stars Gorgeous!
By brian beyer on March 30, 2017
This sink is gorgeous. Couldn't find anything like it at the home improvement stores, so of course we turn to Amazon. Well worth the money. Wanted a single sink, but not the farm house type. This made our kitchen remodel worth the effort.

5.0 out of 5 stars Beautiful, durable, awesome
By Julie Much on March 20, 2020
We love this sink! It is very durable, easy to clean, and looks fantastic. I read the other reviews about arriving broken, but ours was packaged so securely and professionally and we didn’t have this problem. We received a different drain assembly than pictured, but are still very happy. So glad we bought this sink!
