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.

Love the Toto sink that color matches our Toto toilets. We had purchased 3 of the sinks, each in a different color. They are nice and deep as well as wide and long. Only problem is the sink left less room for our faucet to be installed and prevented the drain pop up from working properly because of the backsplash hindering the lever on the pop-up. We ended up having to purchase 3 new pop-up drains to be separately installed.. Karen. Bruce Township, MI. Mon Jan 22 2024
