  • Real Review: Kraus Kitchen Sinks
    Brent Holland of reviews the many great features of Kraus kitchen sinks

  • Minimum Base Cabinet Width: 24"

What's Included:

  • Kraus 16 gauge stainless steel sink
  • Stainless steel bottom dish grid (basin rack)
  • Stainless steel basket strainer (sink drain assembly)
  • Mounting and installation brackets
  • Sink cutout template (for countertop cut dimensions)
  • Dish towel with Kraus logo
  • Specification Sheet / Installation Guide

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. Under the header "We Also Recommend These Similiar Products" you will find 5 kitchen combos that include this sink. All kitchen combos that use this sink can be found by typing "KBU12 combos" into the search bar at the top right of this page.

Kraus KBU12 Reviews

Rated 5 out of 5 by from Solid, deep and attractive We like this sink because it is attractive, deep, and does not clink like thinner gauge sinks. Its smooth, no angles design cleans easily and looks appealing, particularly as an undermount sink as the curved corners are reflected in the counter-top cut out above the sink. The deep nature, which is deeper as an undermount, as its lip sits below the counter, allows lots of items to be put in the sink, and yet not be too apparent from the surface (our old shallow sink fit hardly anything and it was very obvious when we had a build up of items in there). Finally, this sink makes hardly any noise when you put items into it due to its 16 gauge material - a real treat after our old tinny-sounding sink. A top quality sink.

Rated 5 out of 5 by from GREAT Sinks I love this sink. Its smaller than my old one but its perfect because I wanted more granite than sink. I love the 18 gauge quality, rack in the bottom, drying towel and the Kraus logo. Its got more quality that I imagined and cost less than local stores. It was so impressive, I bought two more Kraus sinks for the bathrooms and got the same high end quality.

Rated 4 out of 5 by from Really a fantastic value! I love almost everything about this sink. I'll start with the one con and then you can read the many, many pros. The mounting hardware was made of plastic and almost all of them broke or fouled during installation. We ended up going to Home Depot to buy different fasteners made from plastic so we could install the sink. Other than that, it looks terrific installed and the metal grate at the bottom keeps my ceramic bowls (and everything for that matter) from scratching the basin. It is 9 inches deep and with my 2 inches of concrete counter tops you can never tell that there are coffee mugs and plates in the sink. Keeps the kitchen looking tidy. I love this sink and would recommend to anyone looking for a contemporary sink at a reasonable price.

Rated 5 out of 5 by from Best Sink for the money Can't say enough about this sink. Worth every penny and it didn't cost a lot of pennys. With all that comes with it, it was perfect for our single undermount placement. You won't be dissapointed if you buy it.

Rated 5 out of 5 by from Love It! I would highly recommend this company. Everything was handled with ease. Shipped great no problems at all. I love this sink very high quality and very easy to install. Looks great and everybody loves it. This sink was half the price of the big box stores with a higher quality metal. Thanks Again Faucet Direct for everything....

Rated 5 out of 5 by from great sink I bought this sink for my galley kitchen. I needed to save a space for countertop working area but I also wanted to have a good quality and capacity sink. This sink is what I needed for me and my family. Looks very nice, the quality is good and 9" deep makes it very comfortable for washing and storing dirty dishes before they go to the dishwasher. I love 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.
