Nantucket Sinks UM-18X12-W Undermount Bathroom Sink White

Product Description

The NANTUCKET SINKS UM-18X12-W is a rectangular undermount bathroom sink made from vitreous china with a white enamel glaze finish. It measures 21 inches x 14 inches overall with an 18-inch x 12-inch interior basin and a depth of 6.75 inches. The sink features a scoop bottom profile that supports comfortable daily use. Designed for undermount installation, it includes an overflow and a standard 1.75-inch drain opening. A mounting template is included; the drain assembly is not. This sink is intended for installation by a licensed plumber or experienced tradesperson in residential bathroom applications.

This sink is sized to fit a 24-inch vanity cabinet and suits primary or shared bathrooms where a mid-size rectangular basin is appropriate. The crisp rectangular profile and classic white finish work across a wide range of vanity styles and countertop materials. The scoop bottom design provides usable interior depth without requiring an oversized cabinet footprint. Dimensions may vary by up to 0.25 inches, which is standard for vitreous china products.
