Elongated Oval Ceramic Undermount Bathroom Sink with Overflow, 22.8"

The basin installs using standard undermount methods, set beneath the countertop with clips, brackets, or adhesive bonding suited to the deck material. It works with stone, solid surface, and other rigid countertop substrates that can carry an undermount load. Installers can specify a positive, flush, or negative reveal depending on the look and the fabricator's preference. Mounting hardware scope is confirmed at quotation.

Faucet drilling is handled in the countertop deck or wall, not in the basin. The sink carries no faucet holes, which leaves specifiers free to set single-hole, widespread, or wall-mounted faucet layouts per project.

The basin has a single rear-offset drain opening, set approximately 100 mm (3.9 in) from the rear edge. The drain opening is Ø45 mm (1.8 in) with a Ø70 mm (2.8 in) seat recess and accepts standard lavatory drain fittings.

This basin is supplied without an overflow, so it must be paired with a non-overflow, free-flow drain. A standard pop-up drain with an overflow channel will not match this basin. Confirm the drain fitting at the specification stage.

The basin is made of ceramic and formed as a single-piece undermount bowl. The undermount format keeps the rim concealed beneath the countertop, leaving a clean countertop surface around the basin with no exposed lip to catch residue. Finish and color options are available on request.

This oval ceramic undermount basin suits trade buyers sourcing lavatory sinks at volume:

• Distributors and importers building a bathroom basin catalog
• Private-label brand owners adding an undermount vanity sink to their line
• Multifamily and hospitality buyers specifying a repeatable basin across many bathrooms
• Showroom dealers and countertop fabricators supplying remodel and new-build work
• E-commerce resellers listing undermount bathroom sinks online

The consistent oval form and standard drain opening make the basin straightforward to specify, template, and install across repeated units.
