    Dimensions and Bowl Capacity of This 22 Inch Undermount Bathroom Sink

    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.

    White Ceramic Undermount Sink Finish and Color Consistency

    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.

    Installing a Ceramic Undermount Sink With Overflow

    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.

    OEM, ODM, and Private Label Options for Rectangular Undermount Basins

    SANIKB manufactures the SN025 factory-direct and supports OEM and ODM programs for buyers who need a rectangular undermount bathroom sink customized to their requirements. Custom dimensions, alternate configurations, and tailored documentation are available on request.

    Private-label brand owners can have factory marks removed and replaced with their own branding, with custom packaging and rebranded spec sheets set per program. Private-label MOQ, exclusivity terms, and packaging are scoped during quotation.

    Bulk Supply and Project Applications

    As a stocking and project SKU, the SN025 supplies a range of B2B channels: plumbing and bath distributors stocking trade inventory, importers bringing in container volumes, multifamily and build-to-rent developers buying at unit scale, hospitality FF&E buyers specifying to a property standard, showroom dealers, general contractors, and e-commerce resellers.

    Export packaging, container loading, and breakage protection for this ceramic basin are specified per order. Pricing, MOQ, and lead time are set per program.

    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.
