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 Grids (Basin Racks) and Basket Strainers (Drains): 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 grids along with the basket strainers 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. Under the header "We Also Recommend These Similiar Products" you will find 5 kitchen combos that include this sink.

Rated 5 out of 5 by from Great under mounted stainless steel sink We installed this kraus sink when we recently put in granite counters. I like the 70/30 configuration which gives me a larger part of the sink for bigger pot and pans.

Rated 5 out of 5 by from Great Sink!! After a lot of research I purchase a Kraus sink online. This sink looks very high end but was very affordable. I love it!!

Rated 5 out of 5 by from Great Sink Bought this sink in April and it was installed on 5-29. The installer stated that he has had problems with foreign brand sinks, after he installed it (connected the drains and the faucets) his comment was that he had no problems and was surprised. I haven't used it very much, but so far it has performed well. My husband likes the grills in the bottom of the sinks. It was packed well and shipped promptly. The protective bag was nice and now my husband is thinking of ways to use it, unless I think of something first. The sound proofing is really good.

Rated 5 out of 5 by from great product and price Love the sink. Top quality with features and extras that beat the big box stores. Price much lower and more for your dollars too. Looks great and the sound proofing makes it much quieter when using the sink and the garbage disposal.

Rated 5 out of 5 by from Krause 31 1/2" 70/30 undermount sink LOVE this sink! It is beautiful! My contractor had no problems doing the undermount on my new granite countertop. He even commented on how nice it was. It is heavy duty, looks sharp, cleans up nicely. The 70/30 split is nice for food prep leaving lots of space on the larger side for clean up. No cons for this one.
