Kohler 37907-NA Undermount Single Bowl Kitchen Sink

Product Description

The KOHLER 37907-NA is a large-format undermount single-bowl kitchen sink constructed from stainless steel. Measuring 45.75 inches in length, 19.06 inches in width, and 12.87 inches in overall height, it is built for high-demand residential kitchen installations. The bowl depth reaches 11.0625 inches, providing ample room for oversized cookware and prep work. A three-tiered internal ledge system allows accessories to be staged at different heights during use. The sloped bowl floor channels water and debris toward the drain, reducing cleanup time. This sink ships with a drain cover and two dishwasher-safe sink racks included in the box.

The 37907-NA is designed for residential undermount installations and requires a minimum cabinet width of 48 inches. The large single-bowl configuration suits kitchens oriented around heavy cooking, batch prep, or entertaining. Licensed plumbers perform the undermount installation, which involves cutting the countertop substrate to the template dimension, applying sealant, and securing the sink with clips or brackets rated for the sink weight. The included sink racks rest on the three-tiered ledge, keeping cutting boards, colanders, and prep tools elevated above the basin floor.

Installation Notes

Undermount sink installation should be performed by a licensed plumber in accordance with local plumbing codes.

Apply a continuous bead of silicone sealant rated for kitchen sink use along the entire perimeter cutout before setting the sink. At 45 pounds, the sink requires a two-person lift to position safely during installation.
