Reviews

I couldn't find the sink-faucet combo that I was looking for, so I ordered each item separately and got exactly what I wanted for under what others were offering as a combo price. Thank you, Wayfair, for making my dream kitchen a budget reality. I will continue recommending you to my friends and family when the opportunity arises.

Beautiful!

Replaced a dual stainless sink which we hated because it was ugly and too small. This sink added a nice updated look to our kitchen and the fact that it had a duel mount option was a plus. Our handyman was able to install this in just a short time and now we get many compliments from visitors about how nice it looks and how functional it is.

Great Sink

Was an awesome sink, just didn’t fit. The customer service is where it’s at though. Getting the sink returned was so simple. Definitely use this family owned business. Support the little guys.

I love it. It’s gorgeous. But you have to keep it clean. Don’t let dishes sit in there for too long otherwise it leaves a little stain. You can scrub it off with some elbow grease, but it’s better to just keep it clean and avoid the hassle.

Not Scratch Resistant

I bought this as I wanted a black single sink but after a few days of using it I noticed some scratch on the sink. It supposed to be scratch resistant but I guess it is not. It looks really good on a white countertop though so I gave 2 stars. It will be just a waste of time if I took it out and return it to home depot for an exchange.

Fits the bill for me!

This was just what I was looking for (a wide, deep bowl, sturdy, and true black). Very well packed as I was worried about possible damage but they thought of everything. It is a shame that you have to get a sink strainer for no good reason when you have a garbage disposal, so that is a little wasteful (something for the supplier to think about having as an option to select not getting one)

5 Stars

I love these sinks. They are "top notch" for the price. The size is perfect for most things you would do in a kitchen sink from washing dishes to bathing a baby. I use these sinks in houses I remodel and they always impress buyers of any age. The color looks terrific with brushed nickel or oil rubbed bronze. Accessories can be purchased if you choose.

I love everything about this sink! High quality, durable construction. Beautiful to look at. Although it's not a workstation sink, there is a small lip which will perfectly support a cutting board if you find just the right size. The inside measurements under the lip are 14 1/2 inches, and the measurements inside the lip are just under 15 inches. My cutting board is 14 7/8 inches and fits perfectly as you can see in the picture! This allows us to gain usable work surface in our small kitchen. Installed easily as well, and the pop out for the soap dispenser was easy! The company has several videos on YouTube to help with the installation. I can't say enough good things about this sink! I've been using it for a few weeks now, easy to keep clean. So happy!

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 product, easy install

I used this a drop-in replacement for an existing undermount stainless steel sink. Becuase it is a replacement, the size was not exact for my existing granite opening. However, by installing this as a drop-in; it made it easy to simply cut the granite opening a little larger for this to fit. The install was very easy, but as with anything, I threw out the template and actually measured the area before cutting. The sink itself looks great, its material and color match the granite very well. We are extremely happy with our purchase.

5 Stars

We got this sink about 5 years ago - best decision ever. I'd read reviews to stay away from lighter colored composite sinks, so took a chance on radical black. It's huge, cleans up beautifully, and reviewers are right that the black somehow masks dirty dishes in it. The composite is more forgiving than a porcelain or enamel sink, so we've had very few broken items. There are no scratches or stains (and we're hard on it. Love it.

Beautiful sink! Great brand! Outstanding customer service!!!

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.

absolutely amazing

I've had this sink over a year now. we did put a soap dispenser in. had to finish drilling the hole. but once you have that bit I guess you could put the hole in anywhere which is nice.I just had to leave a review and say that I beat this sink up, and it always looks amazing. I'm so impressed. I make soaps, and body products. so I use lye, and heavy butters and oils and micas. this sink always comes back beautiful with almost no effort.I do recommend drying it and rubbing an oil in, from time to time. super happy. it never looks dirty or stained.

I also posted a review on 9/5/17, but seems I can't edit that one, so writing a second. My initial rating was a 4 star, but after more use (maybe 6 months)... I'm much less satisfied. This sink chips and scratches way too easy. Mine already has a chip and a scratch, and that's while using a sink rack at the bottom, so it's not like dishes, etc. are always directly touching the bottom. No clue how either happened either, because it's not like we're throwing things in it. My second complaint is that the bottom of the sink seems to be much duller than it originally was. Maybe there's a way to resolve this, but have not searched the Kraus site for answers.

I was looking for something that wasn't too outrageously priced, and this fit the bill. A very nice sink for the price. The only reason I did not give it 5 stars was due to the dimensions listed on the product page. I wanted to install this as a drop-in, and according to the dimensions, there should have been just enough (inner basin) room. Nowhere did I see any mention of needing to account for the brackets that secure the sink. I thought that would have been factored in to the measurements. They were not and the sink would not drop in far enough. Luckily I was able to mount it from underneath, so it all worked out. It actually looks better that way, so I can't complain too much.

Attempt #6 is a great sink!

I am very happy with my sink. I've only had it installed for one week so I can't say how durable it is, but I love the look and feel. Installation was easy and I was able to drill an extra hole with no problems.

Looks better in person than online

I love this sink, it is a great heavy duty sink as well as looking gorgeous. The black onyx looks great with a stainless steel faucet. Really sharp. It is not solid black but has very small specks of grey in the black onyx. My only issue is I need a longer wider version of this amazing sink. I bought this size thinking it fit my sink measurements and cabinet interior but unfortunately it's too small. I needed the drop in mounting not under mount and this was perfect, except for the size. My fault for not getting measurements right! I am sad to return this beautiful sink.

Beware of Cracks

I purchased this sink on a Monday and it came in on that same Thursday. Extremely fast. When we went to install it, however, we noticed that three of the corners were cracked. The box had some damage so we figured it occurred in shipping. The company was extremely responsive in requesting us a new sink.
