Foster 2156863 Undermount Stainless Steel Sink Single Bowl

Product Description

The FOSTER 2156863 is a single-bowl undermount kitchen sink constructed from AISI 304 stainless steel with a Foster brushed finish. Part of the KE series, it is built to 18-gauge (1.2 mm) thickness and features heavy-duty undercoating on the underside for corrosion and condensation resistance. Overall dimensions measure 17 5/16 inches x 17 5/16 inches, with a single bowl cavity of 15 3/4 inches x 15 3/4 inches and a bowl depth of 8 inches. This sink is designed for undermount installation in residential and light commercial kitchen applications and is typically installed by licensed plumbers or experienced kitchen contractors.

The 2156863 is suited for undermount installation in residential kitchens and light commercial food-prep environments where a flush countertop-to-sink transition is required. The included undermount fixing kit with brass inserts and clips secures the sink to the underside of solid surface, stone, or engineered countertop materials. The 3 1/2-inch waste fitting with stainless steel basket is included, eliminating the need to source a separate drain assembly. Compatible cutout dimensions are 15 3/4 inches x 15 3/4 inches.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes. Power down any in-sink disposal units and shut off supply lines before beginning work. Apply a continuous bead of silicone sealant around the cutout perimeter before securing the sink with the provided undermount fixing kit. Do not overtighten the mounting clips, as this can distort the sink rim or crack countertop materials.
