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 Fabulous sink We love our new sink. We wanted a large, deep, single sink for our new kitchen. I looked all over and searched many websites and I believe this is the biggest you can get with rounded corners. We are very can fit a lot of dishes in there and they are hidden away from view. The sink comes with a very nice stainless steel rack to go in the bottom of the sink to protect it. It is a nice addition that is not usually included. The price was good and had amazing customer service. When I ordered the sink, it automatically recommended a garbage disposal to go with it, a badger, and I added it and it is working very well too.

Rated 4 out of 5 by from nice sink This is a great sink. Much better than the 2 bowl sink we had before. My only complaint would be that it does not come with the option of a disposal attachment. Had to spend another $60 dollars to buy one that comes with a screen.

Rated 5 out of 5 by from Very impressive but take care. I have had so many compliments on the beautiful appearance of my new Kraus sink. I have not, however, had the joy of using it. Unfortunately our contractor did not take into account the depth of the sink and added insinkerator disposal. Our drain pipe is now too high and the water cannot drain completely. We are awaiting the plumber and the ensuing bill to correct this issue. Please be aware of the implications of a deeper sink. The rack for the bottom of the sink is a wonderful bonus but it has very sharp edges and scratched my sink the first time it was put in. I would have appreciated the warning of how careful one would need to be in placing and removing that item. Even better would have been a higher quality rack that had the edges smoothed. I am very impressed with the beauty of this sink and am looking forward to many years of smiling while I stand at the sink and dream. Take care and it will be a place you can dream too.

Rated 5 out of 5 by from in love I absolutely love this sink it is so big I can put a basin and a dish drain rack in it as though it is a two sink but without the divider. so much room to clean large pots and pans. its really nice and deep. the price was so reasonable for the quality you receive. less expensive than others smaller. you will not be sorry if you purchase

Rated 5 out of 5 by from Great Sink This sink is built well solid and very well insulated. I was even impressed the way it is packed all the way down to the cloth bag it is wrapped in.

Rated 5 out of 5 by from nice big basin This sink was packed extremely well, and arrived in perfect condition. The 30" width is excellent, but I wish I had not gotten such a deep sink. It is about 10" deep, and required some re-configuring of the P-trap due to the placement of our drain in the wall. However, it does hide all of the dirty dishes, and can hold large deep pots. It is quite heavy, and the countertop installers said not to place anything heavy in this undermount sink, especially since the large, heavy garbage disposal is also attached to it. I think we will brace it underneath with a 2 X 4, just for good measure since it is an undermount. We have only been using it for a few days, but it seems like a really good quality sink. I won't know for a few months or so whether the finish will be the quality that we expect it to be, but I am happy with it so far. It also has good sound-proofing, which is a feature I had looked for in a sink.

Rated 5 out of 5 by from Christmas in the Kitchen This sink is a gift I gave myself to last for many years. This sink is well worth the difference in price in many ways. It looks fantastic, is much sturdier than lesser gauge SS, the single bowl gives so much more space to work. The drain, strainer, and stopper hardware, one beautifully integrated unit, are chic. Who knew sink hardware could be chic? The rack in the bottom prevents dents and dings, is easily cleared of debris with about an inch between it and the sink. Great idea! I cannot say enough good things about this sink. I would definitely buy again.
