Product Overview

The Vault undercounter single-basin apron-front sink features an innovative shortened, Self-Trimming apron. Unlike most apron-front or farmhouse sinks, the Vault apron-front sink can be installed in new standard cabinetry or retrofitted to existing standard cabinetry, and does not require a special apron-front cabinet. This makes it ideal for kitchen remodeling situations. The sink installation requires only that the cabinet's false drawer front be removed and a simple cut to the face of the cabinet be made. The unique Self-Trimming apron overlaps the face of the cabinet, ensuring consistently beautiful installation results. This sink is designed to fit in a 36 in. base cabinet, and the 9 in. deep basin, tight corner radii, and rear-oriented drain maximizes usable work space within the basin.

  • 35-1/2 in. x 21-1/4 in.
  • 9 in. basin depth
  • Undercounter installation
  • Includes one bottom basin rack
  • Features an innovative self-trimming apron to ensure consistent, successful installation results
  • Shortened apron allows sink to be used in standard cabinetry or retrofitted to existing cabinetry
  • Fits a 36 in. base cabinet
  • Can be used with garbage disposal

Customer Questions & Answers

We have already purchased this sink. However we are now faced with installing it in a cabinet that is 40" from cabinet wall to cabinet wall. Is there

a guide or set of installation suggestions available to make this work? If nothing already exist then I'd like to ask if this can be done? If yes how? I picture a some sort bracket/stand? Has this been done before? Thank you.
Asked by: Uniquedesign
Yes it can be done but you have to get creative and build a custom support bracket for below. a 2x4 wood frame. you will also need to support the left and right side sink over hangs..

There is a couple of other brands out there that offers a retro fit sink, you will just need to search for them. I would highly recommend you don't go with this Kohler sink. They have quality issues with the finish.

Vault Undermount Stainless Steel 36 in. Single Basin Kitchen Sink Kit is rated 3.3 out of 5 by 7.

This sink was the worst home design purchase I've ever made and due to it being an undermount design, the cost and difficulty to remove it means we are stuck with it. This sink got scratches on it beginning day one. It is also horrible with water spots. The square corners and flat surface result in it retaining food and water that are nearly impossible to get cleaned out completely so it is unsanitary. The rack collects food debris on it so it needs to be cleaned and sanitized daily. I'd remove the rack but doing so would result in every pot or pan I place in it creating more scratches. We have had this sink for close to 2 years now and I have been sorry every day that we do. A low-end $69 sink would have held up better. We never dreamt that a Kholer product would be so shoddy and it's likely I will steer clear of them for any future purchases.

Rated 3 out of 5 by from I have a love hate relationship with this sink. I will start by saying I love the look of the sink. I love the fact it's a Kohler, and stainless steel and farmhouse sink...always wanted one and got one. I love the fact we did not have to retrofit the cabinets to accommodate this sink and install was pretty easy with my new granite countertops. I did love the fact it had the rack to protect the sink bottom from getting scratched. I will have to follow up with I hate the fact it is so squared in the corners that water tends to stay there and then looks chalky from any calcium in the water if you don't rinse it out well enough. There is not any slope downwards towards the drain to allow water to flow easily into the drain from the corners. So get ready, when trying to rinse out the sink, you get a nice shower when rinsing out the corners when the water splashes back up at you. The rack is a nightmare. Only thing great about it is it protects the bottom of the sink from getting scratched. I was always having to lift it out to rinse and clean water stains/spots from the sink bottom. And forget rinsing ears of corn as the strands from the inside of the husks would get stuck and hang from the rack, as does spaghetti if it slips out of the strainer when rinsing and any other type of "stringy" food item. That rack is now stored up in the attic and I can now actually use and clean the sink properly. So I'm torn~ Paid too much to get rid of it now and maybe the Kohler name will impress the next homeowner when we sell our house. But this sink is a chore every day. I was so happy with my cheaper stainless steel sloped bottom sink from another competitor. Home Depot was great, ordered online and it was shipped perfectly, no complaints there. Just extremely disappointed with the Kohler name on this one.

Rated 1 out of 5 by from Do Not Purchase This Sink. Quality Issues!! I purchased the Kohler Vault 36" Apron Front Sink for a kitchen remodel at my home. We ordered and received the sink from Home Depot. I left the protective film on the sink while I installed it. After installation I took the film off only to realize that the sink has a weld mark on the face of the apron. This is an obvious blemish and I thought that the Kohler quality inspectors just didn't catch it. So I uninstalled the sink and ordered a new one to replace it. We took the first sink back to Home Depot for a refund as they will not just switch it out. The second sink arrived yesterday and I inspected it before installation. It has the same blemish. Its as if someone has hit the sink apron from the back causing a dent that protrudes from the front. I now suspect that this is not a random issue and that Kohler is aware of it. I just got off the phone with Kohler customer service. That was a waste of time. The customer service rep said they have no complaints listed for this sink. I asked her how she knows that because I had not given her the style number of the sink. I don't think the Kohler brand carries the same quality that they did years ago. Don't waste your time purchasing this sink. Its not worth the $700 + that HD and Kohler are charging. As for me, I don't have the luxury to purchase a different sink as I have modified my sink cabinet to work with the defective Kohler product. Wish me luck.

Rated 4 out of 5 by from Nice look without cabinet remodel! I love my new sink and the fact that it didn't require a cabinet remodel was a bonus! I was able I use it with my existing cabinets. I love the size of the sink too. I have so much more room and the quality is very good!

Rated 4 out of 5 by from Nice stainless steel apron sink This sink is beautiful. Right out of the box a small weld failed but luckily it did not impact the sink once it was installed. We did have to modify our new sink base to accommodate the sink even though we bought one meant for this model. Installation went well with the help of online videos. It looks great in our kitchen and seems solid. There is some noise when running water into the sink but it is not loud.
