"Love this sink! I bought this sink from Amazon about a year ago and it has been a great addition to our kitchen. It is large enough to soak our largest roasting pan. It is a workhorse. Made extremely well. The sound proofing construction dulls the echoing type sound that most stainless steel sinks have. MONEY WELL SPENT!"

Nice black granite sink
5 Stars
Nice black granite sink
This replaced a heavy cast iron/porcelain sink; it's fairly light, and 1 person can easily get it into place. Pretty good instructions with a clear cut out template--only issue was the included top mount brackets didn't quite work with some of my improvised cabinet bracing I had to do. No big deal, plenty of caulk and she ain't going anywhere. Time will tell how the finish holds up (this went into a rental home). Only thing I didn't quite care for was the stainless accent strip in the center, but no big deal. For the price, this definitely beats a paper-thin stainless sink!

5.0 out of 5 stars Beautiful sink! Great brand! Outstanding customer service!!!
Reviewed in the United States on March 19, 2019
We purchased this sink from Amazon about two months ago. We received it two days later but the right back corner was cracked and detached from the sink. I called Kraus directly on Wednesday morning and spoke to Tony. After emailing him photos of the damage along with a copy of my invoice he said he’d place the order for a replacement which he assured me would go out the same day. Later the same day I received an email with tracking information for the replacement sink. On Friday,just two days later I received a second broken sink. This time it was the left back corner. At this point we were concerned, thinking Kraus would lose patience and somehow make their problem our problem as many of today’s companies do.
I emailed Tony with pictures of the damage and followed up with a phone call sharing my observations regarding the packing and shipping. In both instances of receiving damaged product the packing materials had shifted in the box leaving the larger back of the sink where the faucet is installed vulnerable to the exact damage we were seeing. Tony assured me they would open the box and inspect the packaging before shipping a third sink. At this point we were losing faith but Tony was ‘All in’, understanding that we really had our sights set on having this sink. On the following Monday I received an email from Tony with tracking information and his assurance that the product was inspected prior to shipping. On Wednesday the third sink arrived. The packing tape across the top of the box had come Lioose and my hopes of receiving an acceptable product was diminishing. After opening the packaging I first noticed the sink was whole, no broken corners. I then got a shop light and started inspecting for minor cracks of which there were none. The third sink arrived in perfect condition!
Originally we planned to have the sink professionally installed but with the delay we now had scheduling conflicts with the installer so I decided to do the installation myself. While the clips that secure it to the underside of the countertop (this was installed as a top mount) were a bit tricky we did get at least one on all four sides. The installation, including our existing R.O.filter, a net Delta ‘Touch 2O faucet took about 3-4 hrs. We did get tripped up a bit as we had to get creative with the new placement of the drains but in hindsight, successful science projects are a lot of fun!
Bottom line....We love this sink!!!! In reading reviews we’ve noticed several people talk about ‘Hard Water’ spots and whiteness. Our water is by no means soft, by the same token, it’s not West Texas hard either. A good example of our water is, DO NOT wash your car in the heat os the day.... It will leave spots regardless of how quickly you work to wipe it dry. Having said that, after a month or so, we’ve found NO WATER SPOTS in the sink.
Bottom line 2.0...... Customer service.... Kraus earns TEN STARS! They absolutely earned our business and recommendations. So many companies today operate with an unfortunate motto of “We don’t care and it shows”. Not the case with Kraus. They absolutely care and will definitely earn your business given the chance! Their customer service is absolutely outstanding!!!
