The SN016 is a narrow rectangular ceramic undermount sink built for bathroom programs where counter depth is limited and vanity layouts need to stay tight. The basin measures 20.9 in long by 13.8 in wide by 7.1 in high (530 x 350 x 180 mm), with a clean rectangular profile and radiused interior corners. The undermount design sits below the countertop, leaving the deck surface uninterrupted and the faucet set on the counter or wall.

This format suits buyers specifying for high-volume residential and light-commercial bathrooms: multifamily units, hotel guest baths, and showroom or resale catalogs where a consistent, space-efficient basin is needed across many installations. SANIKB manufactures the SN016 factory-direct and supports OEM and ODM programs for distributors, importers, and private-label brands.

FAQs

What are the dimensions of this 21 inch undermount bathroom sink?

The SN016 measures 20.9 in long by 13.8 in wide by 7.1 in high (530 x 350 x 180 mm), with a bowl opening at the rim of 18.7 in by 11.4 in (475 x 290 mm). Listings often round the 20.9 in length to 21 inches. Interior bowl depth is confirmed at quotation, and a cutout template is provided on request for countertop fabrication.

Does the SN016 ceramic undermount bathroom sink include an overflow?

Yes. The basin has a front overflow, so it pairs with a standard pop-up drain with overflow rather than a no-overflow free-flow drain. Confirming the matching drain type at the trim stage avoids drainage and fit problems at installation.

What is the drain opening size, and is a drain included?

The center drain opening is 1.8 in (45 mm), set in a molded recess of 2.8 in (70 mm). Drain hardware and pop-up assemblies are not included with the basin unless added to your order, and those options are quoted per program.

Can SANIKB supply this white ceramic undermount basin as an OEM or private label product?

Yes. SANIKB manufactures the SN016 factory-direct and supports OEM and ODM programs, including private label with custom packaging available on request. Finish, drain configuration, and branding are set per program.

What is the MOQ and lead time for wholesale orders?

MOQ and lead time are confirmed at quotation, since they depend on order volume, customization, and packaging requirements. Send your project specifications and target quantities and our OEM team will scope the terms for your program.

Are samples and certification documents available?

Samples are available on request so you can check the white finish and surface before committing to volume. Certification documentation, where applicable, can be provided on request and confirmed at quotation.
