Excellent sink and Wayfair service

Bill from Raleigh, NC– Verified Buyer

The sink came more quickly than expected and was packaged with full protection.

Once the plumber installed it along with a new Delta faucet, we were on cloud 9! The sink is beautiful and the smaller, shallower side on the right fills up quickly when you want to just do a few dishes.

Love it!
