22-Inch Oval Ceramic Undermount Bathroom Sink with Overflow

Inside the 560 mm x 425 mm (22.0 in x 16.7 in) footprint, the bowl opening measures 510 mm x 370 mm (20.1 in x 14.6 in), and overall height is 190 mm (7.5 in) per the spec drawing. The rim is 25 mm (1.0 in) wide with a 30 mm (1.2 in) flange thickness, which gives fabricators a defined mounting edge for undermount installation. A mounting and fabrication template is available on request, and the countertop cutout follows the supplied template. Both metric and imperial dimensions are documented on the spec sheet for submittal and fabrication use.

This basin is formed from ceramic as a single-piece oval bowl, which keeps the shape consistent from unit to unit across production runs. Ceramic is a widely specified material for bathroom lavatories in distribution, multifamily, and hospitality work. Material grade, finish, and available colors are scoped at the RFQ stage, so buyers receive specifications matched to the program rather than assumptions. Color and tone are held to the agreed standard across reorders, which matters for projects that ship in multiple phases.

The drain outlet measures 45 mm (1.8 in) at the inner opening and 70 mm (2.8 in) outer diameter. The drain is positioned off-center toward the rear of the bowl, as dimensioned on the spec drawing, which sets the trap toward the back of the vanity cavity. The basin pairs with a drain assembly specified to its drain configuration, and the overflow status and matching drain type are confirmed at quotation so the correct assembly is ordered for each installation. As an undermount basin, it ships with no faucet holes, and the faucet deck is drilled at the countertop or served by a deck-mounted or wall-mounted faucet. Confirm drain and faucet details against the spec sheet before fabrication.

SANIKB produces this oval ceramic basin factory-direct and supports OEM and ODM programs for buyers who need custom configurations. Available customization is scoped at the RFQ stage and can cover branding, packaging, spec sheets, and program-level requirements. Private-label partners can replace factory marks with their own brand before documentation is published. Tooling cost, minimum order quantities, and timelines for custom work are set per program. Buyers evaluating SANIKB as a supply partner can request factory and production detail along with the standard specification package. Start a private label program when you are ready to scope branding and packaging.

The 22 inch oval ceramic undermount sink suits a range of B2B buyers: distributors and wholesalers stocking bathroom basins for trade accounts, importers moving product in container volume, and private-label brands selling under their own name. It also fits multifamily developers standardizing fixtures across units, hospitality FF&E buyers specifying for guest bathrooms, showroom dealers serving trade and retail, general contractors coordinating with the countertop trade, and e-commerce resellers listing online.
