Answer: 
It may depend on the depth of your countertop and where the sink cutout is positioned. I believe ours was very close to the front edge of the cabinet apron front. I don't believe it would have worked in our installation.

Customer Reviews

Rated 3.9 out of 5 by 56 reviewers.
Rated 1.0 out of 5.0 by Great sink, terrible delivery Great sink, but unfortunately after 3 attempts to have one delivered without the corner bent I gave up on Home Depot's ability to properly handle their product. Each sink delivered was bent, each time I spent 20 min+ on the phone, and each time made a trip to the store to return the defective sink(s). After the third attempt I ordered the sink from a local plumbing supply (for less money) and it was perfect and undamaged on the first try. With the massive quantity of product HD handles, you would think they could do better! I recommend the sink, but advise finding another source to purchase it. June 13, 2016
Rated 5.0 out of 5.0 by Very nice sink This sink is massive! Easily holds 3 times more then double bowl we replaced. Very well made. Easy install. Looks fantastic. My wife and I could not be happier with this purchase. Not the cheapest but well worth the price tag. Meets Kohler's expectation for quality and design. January 30, 2016
Rated 1.0 out of 5.0 by Two sinks so far, both came bent and dented We are currently waiting on this Kohler sink # 3 being delivered to our house. The first two sinks arrived at our door with some serious damage. On both sinks the bottom left corner, again similar to other reviewers experiences, was incredibly bent downwards. we thought we could put it in the sink hole and flatten it out, but it still was uneven and looked terrible. Plus there were multiple dents everywhere on one of the sinks. We have even asked home depot to specially wrap and give extra packaging to the second sink, which they did not. If sink #3 comes in as bad of a condition, i am making a formal complaint to Home Depot and i will never shop there again, nor will I ever recommend or purchase any Kohler products! October 28, 2015
Rated 5.0 out of 5.0 by Georgeous sink I bought this sink for my last house. It is deep and wide and perfect for a family that actually cooks and uses cookie sheets, large cutting boards, large pot and pans, etc. I was tired of the double sink that you can't submerge anything into. This sink is really well made and worth the money. It came with a grid to protect the bottom and that worked great too. You will have to scrub the grate with a brush regularly. I ordered this online and it shipped very well packed and arrived on time. You can use this as an undermount sink, but we dropped it into an existing countertop. Has a very modern appearance. I had this sink for 5 years and it held up great. The corners are a little hard to clean and because it's not very slanted, debris doesn't drain easily. It tends to stay in the corners. But a swish of the sprayer and it's fine. I wouldn't let that stop you from getting this beautiful sink. I moved and I miss it! August 30, 2015
Rated 4.0 out of 5.0 by Smooth buying process, minor damage on delivey Great looking sink, well built, large basin for cleaning oversized pots and pans, heavy duty stainless steal finish, bottom slopes properly to allow complete drainage to center. Has provided the finishing touch to the kitchen and finally a happy wife that seemed to struggle with the old double sink. Installation was bait more difficult due to the square corners of this sink, required that I cut out the granite counter corners for proper fit. ALso the anchor clips that hold the sink in should have longer screws, our granite top is thick and required modification to the support clips. January 30, 2016
Rated 4.0 out of 5.0 by Good sink, mediocre grate.. Changing from a two compartment sink to this rectangular one was somewhat of a gamble, having no experience beforehand. Sink comes with a bottom rack, elevated by rubberised little legs, a ring welded in center to make it possible to empty the strainer. Problem is, this ring is welded to the top of the rack, not even with the rack, therefor creating problems when sliding items from one side to the other... Now I am looking for a way to have this corrected, but will have to pay some guy good money for the changes... An other thought is that having the drain to one side would be the way to go, Maybe next time... March 13, 2014
Rated 5.0 out of 5.0 by Great product Very happy with this sink. Installed it into a butcher block counter so I didn't want an undermount for fear of dings on the counter but still wanted the zero radius look. This worked out great. Nice and big and I Iike the bottom rack that came with it. It keeps pots from scratching the bottom and with our pull out faucet you can spray food down the drain without the food getting hung up on dishes that are in the sink. January 14, 2014
Rated 1.0 out of 5.0 by Terrible sink This sink is beautiful and that is the only good thing about it (until you start using it). You better be ready to dry it out after each and every use, it scratches from the slightest touch, if you drop any food while preparing dinner you better clean it up real fast or the stain will be there for ever. If it didn't cost so much I would have this sink pulled out and replaced, but after the price of this sink and plumber cost I would be throwing away a thousand dollars that I can't afford. By the way I only have this sink 10 months and I live alone so there are no kids to blame for the condition of this terrible sink.....If I could it zero stars I would... February 23, 2015
