The new Vault sinks are dual-mount sinks that can also be used in a replacement application. The contemporary self-rimming Vault fabricated sink will appeal to customers who want a significantly differentiated sink without having to replace their countertops. The low-profile 1.25mm rim provides an undercounter or flush mount aesthetic, and makes wiping debris from the countertop directly into the sink basin easier than a typical self-rimming sink, 9 in. depths and tight corner radii maximize usable basin space, and the lowered saddle prevents water from overflowing into the countertop.

  • 33 in. W x 22 in. D
  • Constructed of 18-gauge stainless steel
  • Self-rimming or undercounter
  • 4 predrilled faucet holes
  • 36-inch minimum base cabinet width
  • 9-inch depth
  • SilentShield sound-absorption technology reduces disposal noise and vibration from dishes and running water

Rated 4.2 out of 5 by 46 reviewers.
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 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 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
Rated 1.0 out of 5.0 by Worst experience ever!!!!!!! We had purchased this sink 4 times and had to return four times. The first sink had two corners bent and the following three sinks had the same corner bent. We think they kept sending the same sink even after requesting them to send a note saying what the problem was. We even called the online support and asked for inspection and special packaging. I spent over an hour on the phone with the online customer support to make sure this would happen. When this sink came in (the 4th one we ordered) it had not been special packaged and the same bent corner!! When the home depot supervisor called the online staff to see if they could over night another sink since we have been waiting over 6 weeks and are kitchen remodel could not continue with the counter tops until this arrived the online staff said it was now on back order. What a nightmare and we will never purchase another product this expensive on line again through home depot. July 24, 2015
Rated 3.0 out of 5.0 by Nice Sink, Doesn't Drain Well This is a high quality stainless steel sink that is quiet. This only one of a few choices for a single bowl sink we had with our drop in setup. I love the single bowl (we replaced a double bowl) and the depth. However it doesn't drain very well and I'm wasting a lot of water, by swishing water a lot more than I ever have to get food bits to go down the drain. The bottom should be more angled to encourage movement toward the drain. I'll live with it but won't recommend it to others for this reason. November 9, 2014
Rated 1.0 out of 5.0 by Large but cheap This sink is huge and deep, exactly what I wanted.....but, the stainless steel is ugly, not smooth (feels rough), and spots easily. Cleaning it all day and after each use, but the stainless looks disgusting. It's time Kohler stopped using this cheap stainless and stand behind its name properly. I purchased it because of the Kohler name, but sadly, like a lot of their competitors, their products are not acceptable to me anymore. I prefer to shop at the upscale kitchen, lighting and designer store fronts now. For a few more dollars, you can get something that looks great and you will be proud to have in your home. This sink is not for the person who plans to keep it for the long term - I was, but I will replace it. October 14, 2014
Rated 5.0 out of 5.0 by Excellent Sink Didn't know what we were missing out on when we bought this sink. It is so easy to clean big pans, pots, etc. Unless you need two sink bowls, one sink bowl is the way to go. The only time I think you would need two bowls, is if you have one bowl to wash and another one to rinse dishes in, but with dishwashers, no need to do that anymore. We have owned this sink for about 2-3 weeks now, and we couldn't be happier. Tips for installation: When you install the sink, make sure that you put the clips on before you put the sink in, and turn them so they align with the outer edge. That way you can drop the sink in with silicone, and then turn the clips 90 degrees and tighten once you're under the sink. December 10, 2013
Rated 2.0 out of 5.0 by over priced, low grade stainless steel The sink looks great. The size us very useful. BUT it is easy to stain, scratches easily and the bottom is not angled sufficiently to drain efficiently, so food sticks. The basin rack is essential due to the softness of the metal. It is sold by Kohler as part of the sink and unbundled by Home Depot upping the cost. The price is too high for the quality of the product September 9, 2014
