Absolutely perfect!
As soon as I saw this sink, I knew I had to have it. I was hesitant to get it at first bc I wasn’t a fan of the silver piece in the middle. Now that I have the sink and it’s been installed, I actually don’t mind the silver piece. This sink is beautiful and is so perfect! The quality and style is exceptional as well! A+ Kraus!

Beautiful Sink
Beautiful sink. I don't really have anything negative to say about it. I've only been using it for a couple days so who knows how I will feel once the honeymoon phase is over. Seems well constructed, hopefully it holds up over time.

Absolutely love my new Kraus sink.

Nicest sink we've ever had.
The quality of this sink is high end for an excellent price. I had to cut my sink cutout just a bit to accommodate the lock down tabs but once I had that done installation was a breeze. We matched ours with the KPF-2230ORB faucet and it exudes high end look all the way around. Sink looks like solid granite and has no blemishes at all. Love the added protective center and the touch of stainless really brings out the look of the sink. We are so pleased with it we can't stay out of the

Looks Great
This sink is great looking and deep. We bought to go in our remodeled kitchen. It gives it an updated feel and blends well with our black counter tops and matte black faucet. Very pleased with our purchase. Only issue with installation is that the old sink and this one had different drain locations and most of the plumbing had to be replaced to accommodate for difference.
Durable, High Quality, Beautiful Sink!!
My husband and I just purchased our first home. We decided to go through with a complete remodel of the kitchen and make it fully our taste instead of buying the same cookie cutter kitchens. I spend a lot of time in the kitchen and aside from appliances needing to be high end and high quality, I wanted a sink that would hold up to its name for durable. I had this sink in mind after looking online for MONTHS. I searched every store, touched so many different sinks and materials and yet somehow, I still wanted this particular sink. A lot of reviews claimed it was shipped and delivered broken - which makes sense it could happen. But that doesn’t have anything to do with the worksmanship and quality of this sink. It’s GORGEOUS!!! I am extremely happy with my sink everyone who asks about sinks and sink types, I’ll defintely recommend this one!

Solid construction with nice design.
This model was not my first choice. When the one I originally ordered didn't arrive on the delivery date. I was informed that it was backordered by a week. When that week passed, I received another notification that it would be back ordered for more than an additional month. I was not thrilled with the stainless steel saddle, because it would take two specialty cleaners and extra steps for maintenance. When this unit was left on my doorstep by UPS I was interested to see how well packaged it was, since I'd read a couple of reviews with complaints of the sink being broken in transit. Mine was packed in so much rigid cardboard and closed cell foam that the only thing that could have protected it better was to use a Pelican case instead of a cardboard box. The sink came out of the box perfectly and the install was easy. The holes that are partially cut for multi hole applications can be drilled out with carbide hole cutters, but you'll need one for each hole. I switched to a roto zip with a 1/4" diamond tile cutter and it zipped right through with no surface chipping but some dust. Once all the plumbing was in place, it beat stainless sink it replaced hands down. When perfectly leveled the sink guides everything to the drains leaving the bottom almost completely dry. The sink sounds as solid as the countertop. The stainless saddle is actually one of nice because I can balance a large stainless stock pot between it and the sink lip, instead of placing it in the basin to fill. So far I'm very impressed. That last Star will need to be earned with long term durability.

Good quality. Sturdy.
Looks great. Very functional. Had to add garbage disposal and plumb a little. If I can do it anyone can. Took a day to install.
