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 Worst packaging ever Nice looking sink but didnt read the reviews before I bought. Bought and returned two separate sinks because both had badly damaged corners as a result of poor packaging. The thin rim of the sink is not protected by any foam, a simple fix for Kohler but oh well. Im buying a different sink, spare yourself the headache. May 4, 2016
Rated 4.0 out of 5.0 by Beautiful sink but came dented As many other reviewers noted, the sink came with some bends in the lip. My husband is removing the dents. March 29, 2016
Rated 5.0 out of 5.0 by Perfect for what we wanted. We were wanting a great single bowl sink for the kitchen and this is it. Plenty of room. Easy install. Looks great! Love the grate that comes with it. January 2, 2013
Rated 4.0 out of 5.0 by pleased overall I top mounted the sink and like the low profile this product has against the countertop. The installation could have been improved by having brackets that are socket wrench compatible. The product itself could be further improved with a steeper grade at the bottom of the basin from the edges to the drain to allow for easier drainage. September 29, 2015
Rated 1.0 out of 5.0 by 2 Weeks after Install Replaced an over mount Kohler porcelain sink that was showing wear after heavy use of 13 years and moved it to the laundry after cleaning and polishing it. The undermount Vault sink from Kohler has been installed less than two weeks. It already is showing the black & rust colored pit marks.And it's LOUD. The dampening pieces underneath are not nearly as good as other competitive products in the same price range. The heavy metal sink guard has been in use since the water was turned on to avoid scratching the bottom or sides of the sink. I have used these before for the porcelain sink and they work well. I have city water so it's 'conditioned'. There is not enough slope to this sink to get the water and food particles into the drain. You will waste a lot of water getting it clean after use. I have read that you need to wipe it dry after use. Seriously, it's a sink, water happens. Clearly inferior materials. Unfortunately mine is undermount and it would take serious money and time to get another product installed. I have bought Kohler products for three homes. Time to look at competitive products now. August 26, 2015
Rated 1.0 out of 5.0 by Big and roomy The functionality of the sink is awesome. It's deep and you can get just about anything in it. Standing back it is a nice upgrade to our kitchen. Now the fit and finish is a different story. The 1st one came in dented with an unfinished edge. I had to return it to a store but couldn't reorder at the store. The process was a pain. The new sink came in with a better edge and less dents. The top flange is dented and wavy. The finish quality is poor. This is disappointing after paying close to $500. I have a dozen or so Kohler products in my home. This is by far the lowest quality. August 2, 2016
Rated 4.0 out of 5.0 by Best sink purchase...ever! This is the only sink I have ever purchased (haha), but it is a great sink! It seems much bigger than the previous sink despite being the same dimensions. I guess being a single bowl and 90 degree angles accounts for that feel. I really did not expect to be wowed by a sink, but I am. Only 4 stars because design of the clips to secure the sink to the counter when dropping-in is really poor. I could only get 4 of the 8 tightened. I don't think companies try to install the stuff they engineer and they really should. If you have someone else install it then this does not matter. January 6, 2015
Rated 5.0 out of 5.0 by Beautiful sink, easy install other than clips are not accessible. I looked everywhere for the perfect sink and couldn't believe how hard it was to find a standard sized 22x33x9 inch sink with 1 hole. This one hit the nail on the head. It is gorgeous, rim is near flat, and it is so nice and deep. I love the modern and clean lines and the squared look rather than rounded. I would buy it again and again for another house. This was my first sink install and while I ran into a million problems, none were due to the sink. It was actually the ONLY thing that I didn't have a problem with. January 25, 2015
