18-Inch Round Ceramic Vessel Sink with Single Faucet Hole, White Basin

All dimensions are taken from the factory specification drawing. Both metric and imperial values are listed so they drop directly into your spec sheets and submittals.

• Outside diameter: Φ455 mm (18.0 in), the rounded 18 inch round size
• Overall height: 165 mm (6.5 in)
• Main drain opening: Φ45 mm (1.8 in)
• Drain seat (recessed) outer diameter: Φ70 mm (2.8 in)
• Secondary opening: Φ35 mm (1.4 in); position dimensioned on the spec drawing (60 mm / 2.4 in and 230 mm / 9.1 in)
• Mounting: above-counter vessel, basin sits on top of the counter or vanity

The consistent round footprint helps standardize counter cutouts and vanity templates across a multi-unit order, so fabrication stays uniform from the first unit to the last.

Fired ceramic is a long-established sanitaryware material with a hard, smooth surface that cleans easily, which makes it a practical choice for high-traffic residential, hospitality, and commercial restrooms. Surface finish and color are confirmed per program, so a private-label or project order can be matched to your specification rather than a single stock option. For repeat buyers, finish consistency across production batches can be specified up front, which matters when you restock a line or extend an existing project and need new units to match what shipped earlier.

As an above-counter ceramic basin, the sink sits on top of a finished counter or vanity, with the bowl fully exposed above the surface. It drains through a central Φ45 mm (1.8 in) opening set in a Φ70 mm (2.8 in) recessed seat. Pair the basin with a pop-up drain that matches its overflow configuration: a free-flow, non-overflow pop-up if there is no overflow, or a standard pop-up with overflow if one is present. Faucet pairing and the correct drain are confirmed for your program, and the specification drawing is available to support your submittals.

SANIKB supplies this round basin as a standard OEM ceramic vessel sink and as a customized ODM product. Depending on volume, options can include custom finish or color, branded and retail-ready packaging, barcoding, and adjustments to basin specifications for an exclusive version. Private-label buyers can carry the basin under their own brand, with packaging and inserts set per program. Send your specification, target finish, and packaging requirements, and our OEM team will confirm what is feasible for your order. Start a Private Label Program or Talk to Our OEM Team to scope a customized run.

As a wholesale ceramic vessel sink supplier, SANIKB quotes MOQ and lead time per order, since both depend on finish, customization, and quantity. Samples are available for evaluation and client approval before a bulk commitment. Because ceramic is fragile in transit, units are packed for export and long-distance freight to reduce breakage and damage claims across ocean and last-mile delivery. Phased delivery can be arranged to match a project schedule, so you receive units in line with installation timing rather than warehousing a full order early.
