Nantucket Sinks UM-16X11-W Undermount Bathroom Sink 16x11

Product Description

The NANTUCKET SINKS UM-16X11-W is a rectangular undermount bathroom sink constructed from vitreous china with an enamel glaze finish. Measuring 16 inches x 10.875 inches interior with a 5.875-inch depth, this sink is engineered for compact vanity installations where space is limited. The sloped sidewalls and flat bottom deliver a transitional aesthetic that suits a range of bath fixture styles. At 18 pounds, the unit is manageable for a single installer. It ships with a mounting template and includes an overflow port. Drain hardware is not included and must be sourced separately to match the 1.75-inch drain opening.

This sink is sized to fit 21-inch vanity cabinets, making it well-suited for powder rooms, guest bathrooms, and other applications where counter real estate is at a premium. The undermount configuration keeps the countertop edge exposed for easy wiping and a cleaner visual profile. Overall dimensions run approximately 18 inches x 12.875 inches, with an interior basin of 16 inches x 10.875 inches. Installation dimensions may vary by up to 0.25 inches. Both residential remodel and new construction applications are common installations for this sink.

Installation Notes

Undermount sinks are typically installed by a plumber or experienced tile contractor in coordination with countertop fabrication. Shut off water supply and drain any standing water before beginning removal of an existing sink. Use a silicone sealant rated for wet areas and follow the included mounting template for countertop cutout placement. Drain assembly must be purchased separately and should be verified for compatibility with the 1.75-inch drain opening prior to installation.
