20 x 16" Rectangular Porcelain Undermount Bathroom Sink with Overflow in White

This 20 x 16 undermount sink features a wide rectangular bowl with straight sides and a flatter bottom, creating a more usable interior space than traditional oval sinks. Its larger footprint makes it a great choice for primary bathrooms or vanities where extra basin width is preferred.

Made from durable, high-gloss porcelain, the smooth, non-porous surface is triple-glazed for long-lasting protection against stains, scratches, and everyday wear. The clean undermount design complements stone or solid surface countertops.
