22-Inch Rectangular Ceramic Undermount Vanity Basin with Overflow

The SN025 measures 22.0 in x 14.0 in (560 mm x 355 mm) on the outside, with an interior bowl opening of 19.7 in x 11.6 in (500 mm x 295 mm) at the top of the basin. Overall depth is 7.1 in (180 mm).

These figures matter for countertop fabrication. The exterior footprint determines the vanity-top cutout and the minimum cabinet width, while the interior opening sets the basin's usable surface. The 7.1 in (180 mm) is the overall basin depth and is measured separately from the interior opening dimensions.

For accurate stone or quartz fabrication, cutout templates and the mounting reveal are provided with your project quote so they match your fabrication method.

Finished in white ceramic with a glazed surface, this basin has a smooth, wipeable face that holds up to repeated cleaning in residential and commercial settings.

For distributors and project buyers placing repeat or volume orders, white-tone consistency is a common concern, since reorders need to align with units already installed. Finish references and batch color matching for large programs are confirmed at quotation.

This basin installs beneath a stone, quartz, or solid-surface vanity top, with the rim seated under the countertop edge for a recessed profile. Undermount support hardware is matched to your countertop at the order stage. The faucet is mounted on the countertop, not on the basin, since undermount models ship without faucet drilling.

A rear overflow is built into the bowl. Because of that, it pairs with a standard pop-up drain rated for an overflow basin, not a non-overflow free-flow drain. The drain outlet is 1.8 in (45 mm), a standard size compatible with common bathroom pop-up assemblies.

Cutout templates and drain pairing details are set to suit your countertop and plumbing spec.
