Sterling 11447-na Undermount Single Basin Ss Kitchen Sink

Product Description

The STERLING 11447-na is a single-basin undermount kitchen sink constructed from 20-gauge stainless steel with a satin finish. Measuring 24 inches in length, 18 inches in width, and 8 inches in depth, this rectangular sink is designed for under-counter installation in residential kitchens. The deep 8-inch basin accommodates large cookware and provides a clean, rimless appearance once mounted. SilentShield sound absorption technology is integrated directly into the sink body to reduce noise and vibration during use. A licensed plumber or experienced installer typically handles the undermount fitting, which requires proper substrate support and silicone sealing for a watertight bond.

This sink is suited for residential kitchen installations where a flush, undermount aesthetic is preferred. The rimless design and wide undermount lip allow for easy countertop integration with stone, solid surface, or engineered substrates. The 1/2-inch reveal or no-reveal option gives installers flexibility to match the finished look to the countertop edge profile. Mounting hardware (91915) and a cut-out template (1064257-7) are included, simplifying layout and installation on site.

Installation Notes

Installation is typically performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and disconnect existing drain lines before removing any existing sink. The sink deck or countertop substrate must be rated for undermount sink support, and all seams should be sealed with a plumber-grade silicone per the manufacturer cut-out template.
