Kohler K-2991-4 Reviews

Rated 5 out of 5 by from great-looking sink This sink is not only very attractive, but sits higher up on its base so that you don't have to bend yourself in half to use it. Was installed yesterday with no problems. Coincidentally a friend e-mailed me this a.m. to say he saw the same sink last night on an HGTV re-do of a bathroom. The faucets shown are by Danze. Overall am very pleased.

Rated 5 out of 5 by from Great Deal and Fantastic Support With the wide selection of sinks, we were able to find the perfect one for us. When we received the sink, we realized we had picked the wrong color. We contacted Faucet Direct and they accepted the return without any restocking fees. The representative advised us on the color we should get and it turned out to be perfect. I would definitely recommend Faucet Direct to anyone looking to buy a new sink or faucet.

Rated 5 out of 5 by from Great Sink With Style Just put this sink into a bathroom remodel. It looks great. It is my new favorite drop in, self rimming sink to use. It is a good price for a good product and it has more style than a standard oval. Solid product!

Rated 5 out of 5 by from Love My Sink! We had a custom vanity built that is not as deep as the standard bathroom vanity.. When we started looking for a sink the problems arose - none would fit the area intended for the sink plus we needed a drop-in as we were going to have the top tiled. I found my way to FaucetDirect.com and was overwhelmed by the choices. Fell in love with the Tresham drop-in - placed the order and it was delivered to my door two days later! It is now installed in my remodeled bath and everyone loves it.
