Advantages of Stainless Steel over Enameled Cast Iron or Fireclay:

  • Very durable; will never chip or crack
  • Dishes usually don't break when dropped during dish washing
  • Due to relative weights, stainless steel is generally much easier (and less expensive) to install
  • Nonporous; resists bacteria
  • Neutral color fits into almost any décor - matches stainless steel appliances

Product Technologies / Benefits:

  • Extra Thick, 16 Gauge Stainless Steel: Short of paying thousands of dollars, 16 gauge is as thick as sinks come (22% thicker than 18 gauge; 36% thicker than 20 gauge). Thicker steel means a stronger sink (hence the lifetime warranty) while also offering a richer and more robust appearance to the finish that is easily discernible from the white-washed, cheap look of thinner sinks.
  • Premium Grade T-304 Stainless Steel: There are two primary types of stainless steel in the market: T-409 and the higher quality T-304. The difference lies in chromium and nickel contents; T-409 with 11% and .5% respectively, T-304 with 18% and 10%. When added to steel, these two metals prevent oxidation and rust by neutralizing sodium chloride (salt) – a common element in everyday kitchens. While cheaper sinks use T-409, Kraus sinks boast T-304, further lending to the lifetime warranty.
  • Sound Insulated: Sound insulated steel is commonly only thought of in the automobile industry. There, auto manufacturers use spray-on "Stone Guard" insulation to provide for a quieter ride and protect the steel. Borrowing this technology and adding to it, Kraus sinks use Stone Guard insulation, sprayed over rubber sound dampening pads to create a noticeably lower-tone and overall quieter kitchen sink. It also protects your cabinet from underside condensation drips.
  • Included Dish Grid (Basin Rack) and Basket Strainer (Drain): It's a wonder why dish grids aren't included with all sinks; they serve a valuable role. Not only do they virtually eliminate scratches, they allow the sink to properly drain, preventing sink scum and protecting your cutlery. As with all Kraus sinks, this sink includes the stainless steel sink grid along with the stainless steel basket strainer you'll need for installation.
  • Heavily Certified: Kraus has gone to great lengths to be able to provide you, the homeowner, the rest-easy satisfaction knowing that your sink is certified and listed by all the major product testing boards in the U.S. and Canada. This means that this sink is deemed safe to use and that it meets all applicable building codes. Certifications and listings include: UPC, cUPC, CSA, IAPMO, ANSI and SCC.

Special Note:

  • This kitchen sink is available as a kitchen combo with a number of faucet choices. Like their sinks, Kraus kitchen faucets have gained tremendous momentum within the kitchen and bath industry and are highly regarded for their quality, durability, and meaningful innovation. If you are considering a purchase of this sink and also need a new faucet, we urge you to consider the kitchen combos; they truly are a deal.

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!
