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.

Kraus KBU11 Reviews

Rated 5 out of 5 by from Just Perfect! It was tough to find just the right size sink. It has enough room front to back so you can comfortably install a faucet and soap dispenser and it is deep enough to clean pots and not too deep to waste space in the cabinet below where you store your chemicals. Also beautiful finish. Very happy with this choice.

Rated 2 out of 5 by from Not so much This sink must be meant for people who only run water and microwave in their kitchens. It scratches VERY easily. Manufacturer instructions indicate it must be coddled. Looks good new; after a week's normal use it is scratched & spotted forever.

Rated 5 out of 5 by from Great quality great price Ordering was easy, delivery was timely and everything was as advertised. The only thing I would change is the interior finish seems a little rough but will probably become smoother with use. Also the depth was a little more than I expected. Otherwise I can highly recommend this company and product.

Rated 5 out of 5 by from Right out of the "crate" Wow! I read the reviews and made my selection. Kraus brand/sinks were everything the reviews said. Well packed, nice bags for protection and one of them was even "crated" in a firm box with a lid. Quality is in this brand. I am pleased to have made a great purchase. If you are looking for a "bar" size sink as an extra, this is a bit large/deep. I would choose this for one main sink it is substantial.

Rated 5 out of 5 by from Top Notch Sink at a Fabulous Price! I researched many sinks before purchasing this one. The criteria was a heavy gauge, a good look, and a good price. I was about to settle on another none too enthusiastically, when I looked at Faucet Directs site. And there it was. Adorable! Although a few inches shorter than the norm it is also much deeper which is fabulous. It comes with a grate that you have the option to keep on the bottom, I do because it also is very stylish. The gauge is the thickest you'd want, soundproof, the feel of excellent quality. A nice thunk instead of a tinny aluminum sound. Easily installed by my Corian fabricator this sink looks like I spent $1,000! Highly recommended.

5 Questions from the Community
Loading nanoRep

The spec sheet and installation guide show the interior dimension to be wider than the exterior dimension on the diagram. Will this fit in a 21" cabinet (19 1/2 interior width).

The Kraus KBU11 interior dimensions are 18.75 by 15.75, with an outside of 20.75 by 17.75.

Can you install the sink in the opposite direction?

The Kraus KBU11 is able to be installed in the opposite direction.

Is there enough room in a 20" wide cabinet for the faucets? Since the width of the sink is 17 3/4", this only leaves about 2" for faucets.

The Kraus KBU11 needs a 21" cabinet to fit properly.

Can this sink be installed as a drop in?

The Kraus KBU11 is strictly an undermount sink.

why does the installation guide & spec sheet say the sink is 18 gauge when product details say it is 16 gauge

We apologize for the typo. This sink is an 16 gauge sink. The specifications from Kraus come directly from the manufacturer and have the correct information.
