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.

Kraus KBU27 Reviews

Rated 5 out of 5 by from wonderful sink The first thing we noticed was how well packed the sink was. Appreciate the care. The quality starts here. Sink is heavy gauge, nicely finished. Love the depth, and the basket strainer (one side only) is very convenient. The grids for the bottom of the sink are high quality as well, and really finish the look. Between the grids and the sound insulation, this is a quiet sink. And the placement of the openings toward the back, really does open up the under-sink space. Installation, however, was quite a challenge. This sink needs a 36" OPENING, not 36" cabinet as it says in the information. It is not possible to install as instructed in a 36" cabinet. There is barely room for the sink, and not enough room to use the installation brackets. (instructions were not included - went back to the website to obtain). Also, my cabinet is 26" deep, which was perfect. 24" would have been a tight squeeze. The sink was well worth the effort. I'd highly recommend it - to anyone with at least a 38" cabinet.

Rated 3 out of 5 by from okay Ordering process was easy. The size ,shape, and packaging of this sink are great. Installation was easy. I was surprised that the drains were made of plastic. Expected metal for the price. Unfortunately, the delivery person doesn't allow you to open the box while they wait, so you can't inspect for flaws etc., as recommended by the website. The center divider of the sink had a scratch in it at time of delivery.I couldn't postpone the sink/countertop installers, so had to keep the sink. It's only been a few weeks and the sink bottoms already show scratches from the plastic covers that are on the legs of the grids. Will think twice before ordering by internet again

Rated 4 out of 5 by from Large and beautiful!! We just got this installed in our new kitchen. It is super big and beautiful! I can't speak for if there are issues with a 36" cabinet since we used a 42" one. Also, I only gave it 4 stars since I can't speak for longevity. Hopefully it won't scratch too bad or at all!

Rated 5 out of 5 by from Excellent Sink - Kraus KBU27 We recently purchased this sink to round-out my bride's remodeled kitchen. After searching at many of the dealers within our area, we couldn't find exactly what we were looking for ... until we found this one online. It is filling the bill perfectly, and I could definitely recommend it to anyone.

Rated 5 out of 5 by from Amazing quality I thought there must be something wrong with this brand b/c it was cheaper than most and had a stronger guage of steel but NO it is just way better. Such a beautiful sink and not one problem. I have had for about two months and I love my sink!!! The big side is good for hiding dirty dishes until I'm ready to wash. I keep the other side clean for washing veggie and fruit. Kruas is definitely better or the same quality than other brand names but WAY LESS costly. Thanks Kraus - you'll have my businesss again!
