I love it!
I love this sink, it adds absolutely beauty to my kitchen! The basins are very deep which I like (I used to have a very small sink 😬), and it nakes my kitchen looks modern. Just be aware the sink isn’t matte black, it’s speckled.

      High maintenance
      I installed this sink 6 months ago and I thought the quality and looks were excellent. Having owned granite sinks before, I thought this one would be easy to care for also. I should have read the care directions before purchasing it. My bad. Apparently, the granite composite material it is made of is porous. If you don't wipe it down after each use as recommended, you start getting water stains and graying. I'll try coating with mineral oil which some says is the best solution.

        Stock photo dimensions are misleading
        Picture shows measurement from inside as 17”, but inside is only 13”. Much smaller than advertised. Why not call it like it really is?

            Nice upgrade. Easy install.
            I replaced a 33 x 22 stainless steel sink with this one. My counter is a beige granite, so the new sink really stands out. I did a drop-in mounting because the hole for the previous stainless sink was the perfect size for drop-in but too big for under-counter mounting. Although the drains on this sink are farther to the rear, my plumbing only required a few shortenings. I went with a new Kraus faucet to complete the look.

              excellent buy
              beautiful sink easy to install but make sure if you are replacing it with a shallow sink, you have enough room as this is a deep sink and strainers are in the back and not middle like most sinks. also, it does have knock out holes, but you will need diamond cutting drill bit.

                Frustrated
                I ordered this because it was supposed to fit according to their measurements. But the size of the bowls are not correct. Says 14.25 front to back but clearly it's not. The actual width is 15.5 which is really frustrating getting it ready to go in and won't go all the way.

                  Beautiful but cracked
                  Bought the sink from Home Depot Canada less than a year ago. I was cleaning it and felt a variation turns out to be a crack running down the middle. Crack seems to be getting bigger.

                    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!

                      What a Sink!
                      This sink is EVERYTHING! It is durable, stylish and well made. The bowls are deep and it comes with a great strainer bucket (cute) , stopper with a good seal and a cloth to wipe it down. I am very very please and it was a super duper price.

                        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.

                          Good looking kitchen sink
                          This black kitchen sink was purchased in Oct at my local store and installed on Nov 18th along with the quartz countertop as part of the reno in the house. The sink installation was a bit of the challenge since it required trimming and gable adjustments to let it sit properly so I got worried with the turnout. I cannot be more pleasant with it. Good looking and very functional. I am giving 4 stars for now hoping to add the 5 in the near future after confirming that the metal accent in the center (which is great btw) is actually good quality and will not rust any time soon.

                            Great sink for drop in application
                            I was hoping for an undermount application and a larger sink, but we didnt have the space/depth for it. This was a great alternative. It is a beautiful black color. It was difficult to get a straight answer as to how many knock out holes there were. Everyone was saying just one hole for faucet. But after confirming with Kraus, there are four additional knock out holes that can be used for a sprayer, soap dispenser, disposal button, etc. and using them does not void the warranty. When I asked our fabricator if they could drill them out they said no. But after telling them i spoke to Kraus directly, they changed their tune. I just don’t think they like to do it in the off chance something goes wrong. But the installers were so great and they drilled the holes with ease and said they do it all the time. The sink is great and big enough for what I need. But I am so glad I did my homework first! I definitly recommend this product. Kraus was very responsive and the sink is sturdy, drains evenly and is quiet.

                              Excellent Design, Modern/Contemporary. Easy assembly and Installation. It has been two months and it is giving my kitchen a new whole look. The only concern is the stainless steel plate placed on the center of it. If you don't take care of it, it will scratch easily. Loving the product and quality.
