Small Rectangular Undermount Ceramic Bathroom Sink, 18-Inch

The SN015B is finished in white ceramic with a smooth glazed surface. The single white color coordinates with a broad range of countertop materials and cabinetry, which helps showroom dealers and project specifiers match the basin across a full bathroom package. A uniform white shade also supports shelf presentation for stocking distributors and a matched appearance across multifamily and hospitality installs, where each unit must match the next.

As a rectangular undermount bathroom sink, the SN015B provides usable bowl volume within a small exterior footprint:

• Exterior footprint: 465 x 350 mm (18.3 x 13.8 in)
• Interior bowl opening: 415 x 300 mm (16.3 x 11.8 in)
• Rim width around the bowl: about 25 mm (1 in)
• Interior bowl depth: about 185 mm (7.3 in), nominal 7 1/4 in

The interior bowl depth of 185 mm (7.3 in) is the depth of the basin itself and is separate from the overall installed height once the basin is set beneath a countertop. For cutting and templating, the exterior footprint and interior opening above give the working dimensions, and the SN015B spec drawing provides the full cutout reference. As a compact undermount bathroom basin, it fits tight vanity layouts without crowding the faucet deck. Request the spec sheet through Send Us Your Project Specs to confirm fit against a specific vanity or countertop layout.

The SN015B mounts under the counter and is secured from below, which keeps the countertop edge clean and uninterrupted, with no rim resting on top of the surface. As an undermount basin it has no faucet holes. The faucet is mounted on the countertop deck or on the wall, so the faucet drilling is handled on the counter rather than on the basin. As an under counter ceramic basin, it pairs with a deck-mounted or wall-mounted faucet of the buyer's choice.

The basin has a standard drain opening of Ø45 mm (Ø1.8 in). The spec drawing also shows a Ø70 mm (Ø2.8 in) outer dimension at the drain well. The drawing shows no overflow on the SN015B. A basin without an overflow must be paired with a non-overflow, free-flow drain that has no overflow channel. A standard pop-up drain built for basins with an overflow is not the correct match for this model. Drain selection and mounting hardware are confirmed at the RFQ stage, and confirming the drain type before installation prevents drainage problems on site.
