Its clean rectangular profile and white ceramic body suit residential, multifamily, and hospitality projects where a recessed undermount ceramic vanity basin is specified beneath a stone or quartz countertop.

This model is sold to distributors, importers, private-label brand owners, multifamily and build-to-rent developers, hospitality FF&E buyers, showroom dealers, contractors, and e-commerce resellers. It is positioned as a stocking and project SKU rather than a single-unit retail item, with OEM and ODM support available for buyers who need a wholesale rectangular undermount sink under their own brand.

FAQs

What are the exact dimensions and depth of the SN025 undermount sink?

The SN025 measures 22.0 in x 14.0 in (560 mm x 355 mm) overall, with an interior bowl opening of 19.7 in x 11.6 in (500 mm x 295 mm). Overall depth is 7.1 in (180 mm). This is the full basin depth, measured separately from the interior opening dimensions above.

Does this rectangular undermount bathroom sink have an overflow, and which drain should I use?

Yes, the SN025 has a rear overflow. It should be paired with a standard pop-up drain designed for an overflow basin, not a non-overflow free-flow drain. The drain outlet is 1.8 in (45 mm), a standard size that fits common bathroom pop-up assemblies.

How is a ceramic undermount sink installed under a stone or quartz top?

The basin is set beneath the vanity top so the rim sits below the countertop edge for a recessed look, with undermount support hardware matched to your countertop. The faucet is installed on the countertop, not the basin, because the SN025 ships without faucet holes. Cutout templates and fabrication details are confirmed with your order.

What material and color is this undermount ceramic vanity basin?

The SN025 is a white ceramic basin with a glazed surface. The glaze provides a smooth, easy-to-clean finish for residential and commercial bathrooms. Finish references and batch color matching for volume orders can be confirmed at quotation.

Do you offer OEM, ODM, and private-label options for this sink?

Yes. SANIKB manufactures the SN025 factory-direct and supports OEM and ODM customization, including custom dimensions and documentation on request. Private-label buyers can have factory marks replaced with their own branding, with packaging and exclusivity terms set per program.

What are the MOQ, lead time, and sample options?

MOQ, lead time, and pricing are set per program and confirmed at the quotation stage. Samples are available on request. Send your project specifications to receive a quote matched to your volume and timeline.
