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 "KBU14 combos" into the search bar at the top right of this page.

Kraus KBU14 Reviews

Rated 1 out of 5 by from bad product I have had the sink which I love for 5 years but the grid that comes with it is terrible. The plastic coating splits open and water gets in to the metal and it rusts and molds and can not be cleaned. You need to use a form of stainless that will not rust or put a finish on it which will not chip and crack.

Rated 5 out of 5 by from Perfect Sink This sink arrived promptly from Faucet Direct, well packed and blemish free. It is sturdy (16 guage) and beautiful. I love the included bottom grid. The price is pretty amazing on this product compared with other brands. Very happy with my decision.

Rated 5 out of 5 by from AMAZING SINK AT AMAZING PRICE My wife found this sink online as we did not like to "free" sink that came with the new granite we had installed. It arrived well packaged (if you order this sink it will come with no dents or scratches). It's of great quality and is deep. The rack is a major advantage as well as the drain insert. I reviewed several sinks after my wife found this all the pieces were priced separately (and added up to more than this sink). If you need a new undercounter sink for the kitchen - you need to order this. lived up to everything and will always order from them.

Rated 5 out of 5 by from Excellent online purchase This is our first build. We have ordered probably 90% of our fixtures and appliances online. This particular transaction, the Kraus sink, was the fastest of them all. The sink is beautiful, seems to be of very high quality, and arrived quickly. Thick sound-proofing baffle applied to underside of sink. Very happy with this purchase. If you are building and haven't done this before - a word of advice. Plenty of deals online, but you tend to wait 4 to 8 weeks for the item to arrive. In this case the item arrived in less than 2 weeks, which is almost instantly from my perspective at this point. Would definitely recommend this sink and faucet direct.

Rated 5 out of 5 by from Quickest Shipping EVER! Although we haven't installed our new sinks *3* yet, I must congratulate both Faucet AND Kraus for the awesome packaging and rapid shipment of my order. Ordered on Sunday, the full order was here on Thursday. AND, the shipping was FREE! The packaging of this product was beyond belief. Very well protected with styrofoam, but additionally had a protective drawstring bag protecting the stainless steel sink from any scratches, etc. All concisely packaged in a reinforced box, with additional strapping. Not a chance of damage with this type of packaging. You never know what you're going to get when you order from a webstore, yet we are now extremely confident that this will be our site of choice as we continue our kitchen remodeling project! thank you so very much!

Rated 5 out of 5 by from Sinkalicious I love my new sink. I was very impressed with the grate and metal drain that came with it. You cannot beat the value for the money! The sink is 16 mm and it really is a great buy. The customer service reps were wonderful with my myriad of questions whether or not it would fit in my sink base. They were all right, it fit beautifully! Don't hesistate to get this sink, you will be very happy.

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 5 out of 5 by from Havy Duty Sink with excellent sound-proofing. A+ This sink is top-drawer all the way, including packaging, towel, 2 drains, which are also the best I have ever seen. This is a top of the line kitchen SS sink. You will not find better. Kraus is a name you can trust! The sink is very think, 10" deep and then ends up even deeper when installed under the countertop. So lots of room and they also give you a quality sink grate. Everything from Kraus is top quality. You will be happy you purchased this. And the best price I found was at
