Product Technologies / Benefits:

  • Kraus Granite Composite: Crafted from 80% natural granite, Kraus granite sinks feature the look, feel, and texture of natural stone. A thermal finishing process results in a tough, nonporous surface that is resistant to heat, chemicals, scratching, chipping, and discoloration that will stand up to a lifetime of use. With a variety of size, bowl configuration and installation options, a Kraus granite sink can make a sleek and functional addition to any kitchen.
  • 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 Super Sink The Kraus granite composite sink is attractive and made with quality. The edges are straight and even when installed as a drop in. The price is great and the sink comes with a basket strainer in the supplied drain assembly.

Rated 5 out of 5 by from Worth the wait. Remodeling our kids kitchen and we wanted to go with something other than stainless. We began looking for a black granite composite sink and came across this Kraus sink. My wife & I had purchased a Kraus stainless sink for our home a few years back, so we knew the quality was very good. Nobody came close to the price that Faucet Direct was offering but the only problem was that it was out of stock. The estimated ship date was missed and we ended up waiting about six weeks. We were able to arrange our remodel schedule around the delay and work other sections without tearing up the entire kitchen. When the sink arrived, we knew it was worth the wait. The sink looks awesome against the butcher block counter tops. The quality is great and met our expectations. Faucet Direct kept me informed of the delivery date and offered a future purchase certificate for the inconvenience. I should note that we had used Faucet Direct before and will again when we remodel our daughter's bathroom next month.

Rated 2 out of 5 by from Engineered by the Blind? Sink surface is nice, and looks good in my kitchen but installation was a nightmare. Kraus gives you a template for cutting a hole in the countertop, but when you put the clips around the sink and go to drop it into countertop it doesn't fit. If the countertop was cut bigger the sink would have barely been hanging onto 1/16" of countertop. The sink strainer is really nice, but again the top of the strainer doesn't connect to the bottom piece because the proprietary screw provided by Kraus isn't long enough. So the carpenter had to silicone the sink into place without the clips, and I had to purchase a separate sink strainer for the plumber to install. Maybe that's why the sink was on closeout and marked down. Frustrating experience because I had to pay the plumber to come twice, plus the purchase of the additional sink strainer it turned out that I didn't save any $ on the mark down.

Rated 5 out of 5 by from This is the Best Sink Ever My wife and I are very happy,now that we have this sink installed. Every thing about it is so perfect, you can wash large pots and and pan with no problem at all because it doesn't have a divider and it is very deep.

Rated 4 out of 5 by from Great sink - poor instructions Although labeled to match the sink the cutout template instructions for both the overmount and undermount were the wrong size. Fortunately the granite contractors were experienced enough to bypass the templates. The quality assurance team should review templates periodically.
