It measures 31 inches in length, 22 inches in width, and 6-7/8 inches in depth overall, with a usable bowl interior of 28 inches by 15.75 inches and a 6.75-inch bowl depth. The center drain opening measures 3.5 inches and is compatible with standard garbage disposals. A U-channel mounting system supports installation into countertops up to 3/4 inches thick. Bottom-only sound-deadening pads reduce vibration and noise during use. This sink is installed by licensed plumbers or experienced remodeling contractors in residential kitchen applications.

The single bowl layout provides an uninterrupted workspace suitable for dishwashing, food prep, and general kitchen tasks.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC requirements. Shut off the water supply and disconnect existing drain lines and supply connections before removing any existing sink. Apply a continuous bead of plumber's putty or silicone sealant around the underside of the sink rim before setting it into the cutout, then secure with the provided mounting hardware. Do not overtighten mounting clips, as excessive clamping force can distort the rim or crack the countertop material.
