The Vault undercounter offset apron-front sink with Smart Divide 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. The 9 in. deep basin, tight corner radii, and rear-oriented drain maximizes usable work space within the basin, while the innovative Smart Divide low-profile divider better accommodates large pots and helps keep water where it belongs.

Rated 5.0 out of 5 by 2 reviewers.
Rated 5.0 out of 5.0 by I Love This Sink! I was nervous about ordering an apron sink without having a custom apron cabinet, but the Kohler Vault was incredibly easy to install (we just followed the directions exactly). Our fabricator fit the soapstone counter top perfectly over the rim, and we were good to go. This sink is the first thing everyone notices when they walk into our kitchen--it's beautiful. The design is perfect for washing platters and skillets, but still offers two distinct areas for multitasking. I would highly recommend this sink! December 15, 2014
Rated 5.0 out of 5.0 by Perfect stylish sink for existing cabinet Very few apron front sinks allow you to install with existing cabinets. This one does the trick, with no modifications to the case goods or doors. Very distinctive, yet superbly functional for a cooking family's kitchen. Also, the low, off-center divider between the asymmetrical sink basins is simply brilliant. August 5, 2014
