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.

Rated 4.3 out of 5 by 45 reviewers.
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 1.0 out of 5.0 by Poor Quality Control The first one we received had a crease in the stainless steel. Homedepot were great and expedited another one the next day (in less than 24 hours from returning it!) Except the edges of the second one were not welded / sealed correctly leaving pin size holes in the 4 bottom corners of the sink! The holes were not immediately noticeable but I'm sure it would have leaked once there was water at the bottom of the sink. Poor workmanship for a $500 sink! February 18, 2015
Rated 5.0 out of 5.0 by It is everything I was looking for and the price was right! I've only had it for less than a week, but so far it's great. I keep my dish drainer to one side and still have room to wash a large fry pan in the sink. When I have to wash something extremely large, I don't have to go to the laundry room scrub sink. The depth is also very nice, you can't tell there's dirty dishes in the sink unless you stand right over it. All sinks should be made to this depth. May 28, 2011
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
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.

Rated 4.0 out of 5.0 by No regrets purchasing this sink I instantly knew this was the sink for my kitchen when I saw it. I read the reviews on here for months trying to decide if I should get it or not. It looks fantastic! Even though I followed some other reviewers tips on here on the install, it took me about 4 hours to remove the old sink, disconnect the plumbing, disposal and old faucet. The install of the Kohler sink took about 2 hours out of the 4 for the whole project. The mounting clips were an absolute PAIN to try to tighten upside down. I highly recommend safety glasses because numerous time the clips fell out and hit me in the face or forehead. I did an install on a laminate counter top because we are doing a full remodel and this sink will be under mounted on a quartz counter top later. The edges of this sink are truly paper thin and look great as a top mount. Now onto the actual usage of the sink. Like others comments, there is a problem with food and particles building up not only in the corners but even in the middle areas of the sink. It does take a little more time to rinse out the food debris but the size, depth and aesthetics of this sink make it worth the little extra effort to keep it clean. I really was concerned when I read reviews of the food building up in the sink corners but now it's habit to give it a quick rise out anytime I put dirty dishes in there. I do feel for the price of the sink there should not be angles/corners where food build up. Just some advice: I purchased the Kohler Disposal Flange in Brushed Stainless (and plumbers putty) to go with this sink and a new disposal rubber splash guard. It's the perfect time to replace the splash guard on the disposal to freshen things up. October 21, 2014
Rated 5.0 out of 5.0 by Love our new sink! Purchased the single hole single bowl sink to streamline our kitchen. It's only been installed for one day, but it is SHARP in our kitchen. I read other reviews of this sink prior to purchasing and wanted a good quality sink. I looked at 20 gauge sinks, but ultimately decided to go with this 18 gauge sink. LOVE it. Paired it with Insinkerator Compact garbage disposal and Delta faucet. December 15, 2011
Rated 5.0 out of 5.0 Great sink, HUGE! Very nice quality, fits perfectly in my granite counter after opening the sink hole a little. The lip is so thin, it practically looks like an undermount sink. FYI - for those who are upgrading from a more common, kohler double basin, cast-iron 33x22" drop in sink, your counter will not fit without cutting as this sink is slightly larger. No big deal really. Overall, a super nice and huge sink that can handle the biggest pots and pans. December 11, 2011
