I have a vanity that is smaller than a standard depth. When it was designed, I didn't realize how difficult it was going to be to find a sink that would fit and still leave room for a deck mounted faucet. These sinks were perfect. They arrived quickly, were packed perfectly in foam and a box inside a box -- which kept them safe and sound. The only bummer is that the ring around the overflow is chrome. I need to figure out how to swap it out for nickel. It doesn't feel like it will come out easy and I don't want to damage it trying. I may need to call the manufacturer to figure this out.. Lucy.
