I love these sinks! I was looking for square sinks for our modern style home, but didn't want to deal with puddling water in the corners. This sink looks very sleek and modern without sacrificing function. The only issue I had was with packaging. The sinks were shipped in a box without padding. I ordered 4 and 3 came broken. Wayfair was easy to work with and quickly sent 3 replacements. One was broken out of the replacements, so they sent me one more. Hopefully they will change the packaging!. Anna. Morehead City, NC.

Worked out great. Easy to mount. We had an issue with a different brand being uneven so it had a huge gap in the corner. This sink was perfectly straight and even on all sides. I didn’t have to fill in the corner with excessive silicone like the previous sink that was a different name brand. I should have started with this sink. That’s what I get for trying to save a few dollars.. Sarah. Castro Valley, CA. Wed Jul 14 2021
