    White Ceramic Material and Glazed Finish

    SN038 is a white ceramic undermount sink with a glazed surface. The single white colorway supports unit-to-unit consistency for distributors and developers placing repeat orders against an existing stock color. The glazed finish gives the basin a smooth, wipeable surface for routine bathroom maintenance.

    Color tone can vary slightly between production runs across the ceramic category, so buyers running phased or multi-container programs should request a current sample to set the reference white before bulk release.

    Undermount Installation for the Round Undermount Vanity Basin

    SN038 installs as an undermount basin, fixed below the vanity surface so the countertop edge sits over the rim. The top inner opening measures 14.6 in (370 mm), which is the reference dimension for countertop cutout and template planning. Mounting clips, brackets, and cutout templates are scoped at the RFQ stage and confirmed at quotation.

    The basin has an overflow, so it pairs with a standard pop-up drain that includes an overflow channel. It should not be fitted with a free-flow, no-overflow drain. The 1.8 in (45 mm) drain opening accepts a standard lavatory pop-up drain.

    The basin carries no faucet holes, which is standard for an undermount bowl. The faucet is mounted on the deck or wall and specified separately, so contractors and specifiers coordinate the faucet drilling on the countertop or wall plate.

    Buyer Applications for the Round Undermount Lavatory Sink

    SN038 fits standardized bathroom programs where a round white undermount basin is specified at volume:

    • Distributors and importers stocking a core round undermount lavatory sink for resale
    • Multifamily developers fitting repeatable vanity packages across units
    • Hospitality FF&E buyers matching guest-bath basin specifications
    • Kitchen and bath showrooms specifying for trade and project clients
    • E-commerce resellers listing a defined-spec bathroom basin

    Its 16 1/2 in (420 mm) footprint suits standard single-bowl vanity tops, which makes it a practical 16 inch undermount bathroom sink for builders and project buyers sourcing in quantity.

    FAQs

    What are the actual dimensions of this 16 inch round ceramic undermount sink?

    SN038 is marketed in the 16 inch round class and measures 16 1/2 in (420 mm) across the outer diameter. The top inner opening is 14.6 in (370 mm), and the overall exterior height is 6 3/4 in (6.7 in / 170 mm). Use the 16 1/2 in (420 mm) outer diameter for footprint planning.

    Does this round ceramic undermount bathroom sink have an overflow?

    Yes. SN038 includes an overflow, so it should be paired with a standard pop-up drain that has an overflow channel rather than a free-flow drain.

    What drain fits the white ceramic undermount sink?

    The drain opening measures 1.8 in (45 mm) with a 2.8 in (70 mm) outer flange seat and accepts a standard lavatory pop-up drain. Because the basin has an overflow, specify a pop-up drain with an overflow channel.

    Does the round undermount vanity basin include faucet holes?

    No. SN038 has no faucet holes, which is standard for an undermount basin. The faucet is mounted on the countertop deck or wall and specified separately.

    Can SANIKB supply this ceramic undermount basin for OEM, ODM, or private label programs?

    Yes. SANIKB supplies SN038 factory-direct and supports OEM, ODM, and private-label programs, including custom packaging. Branding, tooling, and color options are set per program and scoped at the RFQ stage.

    What is the MOQ and lead time for the 16 inch undermount bathroom sink?

    MOQ, lead time, pricing, and export packaging are confirmed at quotation. Send your project specifications and order volume to receive an RFQ.
