Product Reviews

Rated 5 out of 5 by from Great new sink Very pleased with this sink. Love the depth especially. Like having the removeable strainer placed under & being separate from the stopper. I was surprised, however, by how low the drain extended down from the bottom of the sink. Because of this, I had to modify the J trap & drain configuration. Sink is quiet when running water into it.

Rated 5 out of 5 by from Excellent Quality Throughout The quality starts with the incredibly careful packing in a very heavy cardboard box, lots of solid foam, and a sturdy draw string bag. Then there's a cardboard template for the cutout, an extra set of feet for the bottom grid. The 16 gauge stainless is solid and the outside is impressively insulated with pads and some kind of spray on undercoating. Installed the sink under a new quartz counter and it looks and works great. Glad we got a single sink to replace the huge double sink that just took up too much counter space.

Rated 5 out of 5 by from "Such a Deal" Ordered our sink and had it in a week. It came packaged so well that if it ever fell off the truck it would have no effect. Beautiful sink at a great price. It's 16 gauge and it cost what others charge for 18 gauge. We like the free grate for the bottom. The sink was installed last week with our new granite counter tops and it looks just great. Being 16 gauge, it seems to be real quite.

Rated 4 out of 5 by from Looks Great Have not had the sink installed yet kitchen still being worked on but it looks like a quality product.

Rated 4 out of 5 by from Good Experience Ordering online can be a gamble but this company can be trusted to take care of its customers. This sink is perfect in our small summer condo. I can recommend it and the service of FaucetDirect.

Rated 5 out of 5 by from Exactly as described! We were looking for a replacement sink to fit in the corner of our kitchen countertop, when replacing the surface with granite. The previous sink was a two-bowl corner unit that was too small to be functional. This single bowl, deep sink fit the bill. Unfortunately, there is a reach which can be uncomfortable when standing at the sink a long time. Good thing that I don't have to hand wash dishes too frequently! My bad, since I should have given thought to that and neither the granite supplier or the designer made me aware of the potential problem. Back to the sink....incredible!!! Heavy duty, nice and deep and the bottom grid is fantastic. FaucetDirect was a joy to deal with. Very prompt delivery and well packaged. Would deal with them and purchase a Kraus product again. Quality through and through.

Rated 5 out of 5 by from 23" Undermount Single Bowl 16 Gauge SS sink Solid - quality - spacious - easy to maintain. Five star without the high price tag!

Rated 5 out of 5 by from This sink is a tank! It's beautiful, love the rounded corners (easier to clean), love the included sink grate, everything about it. But the best thing is how deep and solid it is, it really doesn't clang when you bump it with pans. I know we picked a real bargain with this one when we remodeled! And delivery was really FAST, too!
