The "23 inch" designation is the nominal marketed width. The precise width is 22.9" (580 mm), which buyers should use when matching the basin to countertop cutouts and vanity templates.

This is a rectangular ceramic vessel sink with faucet hole drilled directly into the ceramic deck, so the faucet mounts on the basin itself rather than requiring a separate hole in the countertop. The single Φ35 mm (Φ1.4") opening accepts standard single-hole vessel faucets, and faucet pairing is confirmed per order where a project requires a specific match.

The spec drawing shows a single drain opening and no overflow channel, so the basin pairs with a free-flow (non-overflow) drain rather than a standard overflow pop-up. The drain opening measures Φ45 mm (Φ1.8") inner and Φ70 mm (Φ2.8") outer. Specifying a free-flow drain avoids the fit and backflow problems that occur when an overflow pop-up is paired with a basin that has no overflow. Exact drain hardware is confirmed per order.

As an above-counter vessel, the sink sits on the finished countertop, which keeps countertop preparation and rough-in consistent across single and multi-unit installations.

The body is ceramic, a rigid material widely specified for bathroom basins in residential, multifamily, and hospitality settings. The rectangular form has defined interior walls and a flat rear deck that present consistently across a production run, which supports unit-to-unit consistency for distributors stocking inventory and for project buyers specifying at volume. Surface details can be reviewed against samples before a volume order.

The 23 inch rectangular ceramic vessel sink fits a range of B2B programs: distributor and wholesale inventory, private-label bath collections, multifamily and student-housing fit-outs, hotel and hospitality FF&E packages, kitchen and bath showroom displays, and e-commerce resale. Its standard rectangular footprint and single-hole deck make it straightforward to specify across repeat bathrooms and to reorder for later project phases or unit replacements.
