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:

  • 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.
  • 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.

Product Reviews

Rated 5 out of 5 by from Best stainless sink and so very cheap I spent a lot of time looking at stainless sinks...I have a small kitchen so I needed a standard 2 bowl 33 x 22. I got a 9 inch depth and love it. This sink is 18 gauge, with sound dampening. It has four stainless stain plugs for the faucet holes, and sink hold clips for placement and a counter template. 1 reg drain and 1 disposal drain. Everything necessary. I love everything about this sink and paid 1/2 of what I would have at a home store for this quality. I would buy Kraus again anytime. Best money I've spent for home improvement to date.

High quality and is as presented in every way. Packaging was very good and there was no damage in shipping. Will continue to buy from when the needs occur.

Rated 4 out of 5 by from Deep Sink We changed from a Kohler Cast Iron (must way 100lbs) very small/large sink to this. We never really liked that sink so we are glad to have this 50/50 split. Good: - Well made, solid and light enough for one person to handle - An off the shelf "dish" holder will fit into this sink. Most likely what you buy will have the dishes facing forward/backwards rather than left to right. Install challenges: I used the template to aid with the install. I cut and did a test fit and found my hole was a little small. I cut again and it was a tight fit but it fit. Problem with a tight fit is you really need a small gap, maybe 1/8" or less around the rails to help hold the bracket. You also need to have some counter top to grab onto--my mistake as in the front section I left little space for the brackets. So be warned, make sure you have 1/4" to 1/2" of counter under the cut-out for the brackets to attach. I spent more than an hour trying to get the brackets attached. If you over tighten they tend to pop out. So, that is a negative on this, ideally the rails should be closer together and more stout to avoid this so the sink can be pulled tightly to the counter-top. I suspect most sinks are made similar--I saw a lot of complaints on a Kohler SS sink with similar railing install. If you have a completely flat countertop and cut the hole properly you likely won't have a problem. I wish they would put the 4th hole on the left. That is where we have our disposer and wash our dishes--very few sinks appear to have this option. Including the sink drains (2 of them) was a nice touch. This addition resulted in me buying this Kraus over other sinks. The sink drains can add $20 or more to the project cost so say on top of what your overall cost will be. The ones enclosed are plastic but are very easy to assembly and don't need any of plumbers puddy. We'll see how it holds up in the weeks/months ahead.

Rated 5 out of 5 by from Great Sink Good looking sink, nice fitting and easy to install. The additional insulation on underside of sink is a nice touch to reduce the noises associated with stainless sinks.
