The SN038 is a 16 inch round ceramic undermount sink built for bathroom vanity applications. It is marketed in the 16 inch round class and measures 16 1/2 in (420 mm) across the outer diameter, which gives fabricators and specifiers a true working figure rather than a rounded nominal label. The bowl mounts below the countertop for a clean undermount profile and ships in a single glazed white finish suited to high-volume, repeatable bathroom programs.

For procurement teams comparing round undermount basins, SN038 pairs a standard outer footprint with a defined top opening and drain outlet, which simplifies countertop cutout planning and drain sourcing across large orders.

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.
