18 in. Ceramic Undermount Rectangular Bathroom Sink with Overflow, Under Counter Lavatory Sink Basin for Bathroom, White

This undermount ceramic bathroom sink features a rectangular bowl with an interior size of 15 inches wide by 10 inches deep, and an exterior footprint of 18 by 12 inches with a 6 3/4 inch profile. The drain opening accepts a 1 3/4 inch drain. Faucet and drain hardware are not included, allowing you to pair your preferred fixtures. The ceramic body is fired at high temperature to minimize water absorption and enhance durability, with a triple glazed, smooth surface that resists fading, scratches, and chipping and cleans easily. The undermount installation creates a seamless edge between counter and sink, suitable for a range of countertop materials and installation environments such as residential bathrooms, offices, schools, or hospitality spaces. The white finish helps maintain a bright, clean look over years of use. Cutout accuracy improves with careful measurement after the package is opened, and verification of fit before installation is recommended. This design emphasizes straightforward maintenance, stable performance, and a neutral silhouette that blends with various styles from contemporary to traditional. Because the sink measures differently inside and outside, it allows a slim exterior while providing ample bowl room for routine tasks. It is compatible with standard vanity depths and common plumbing footprints.
