21-Inch Rectangular Drop-In Ceramic Bathroom Sink, Single-Hole

The SN5011 measures 530 mm x 460 mm (20.9" x 18.2") across the outer rim, with a basin depth of 190 mm (7.5") and a rim thickness of 18 mm (0.7"). As a self-rimming ceramic sink, it drops into a standard cutout in the vanity top and the finished rim laps over the counter edge, so it works with common prefabricated and custom vanity tops. The rectangular form and consistent outer footprint let buyers standardize countertop templates across an order, which simplifies installation on multifamily and hospitality jobs.

The SN5011 is a white rectangular drop-in sink finished in glazed ceramic, a hard surface that wipes clean and stands up to daily use in busy residential and commercial bathrooms. The glaze resists everyday staining and cleans up with standard cleaners, which matters for hospitality housekeeping and high-traffic multifamily turnover. SANIKB works to keep the white tone consistent across production runs, which helps buyers keep stocked units and reorders visually matched, an important point for showrooms and multi-unit projects.

The SN5011 comes with one pre-drilled faucet hole at Ø35 mm (1.4"), set for a single-hole faucet. The drain seat opening measures Ø45 mm (1.8") at the inner diameter and Ø70 mm (2.8") at the outer, sized to seat a pop-up drain assembly. Specify the drain type to match the basin's overflow configuration so the waste pairs correctly on install.

As a factory-direct OEM ceramic bathroom sink supplier, SANIKB manufactures the SN5011 in-house and supplies it as a stock model or through OEM and private-label programs. Buyers can arrange custom carton and branding support, and we provide spec sheets and product photography so resellers and distributors can build their own listings and catalogs. Minimum order quantity, lead time, and customization options are set per program and confirmed at quotation, which keeps pricing aligned to each buyer's volume and packaging needs.

The SN5011 suits multifamily and workforce housing, hospitality guest bathrooms, kitchen and bath showrooms, and online resale, where a standard drop-in ceramic vanity basin in consistent volume is the priority. Because ceramic is breakable in transit, units are packed to protect the basin and reduce damage across the supply chain. Export documentation and container loading details are available on request to support importers and trading-company buyers.
