23-Inch Deep Rectangular Drop-In Ceramic Bathroom Sink

This rectangular drop-in bathroom sink measures 590 x 465 mm (23.2 in x 18.3 in) at the rim, with an interior bowl width of 440 mm (17.3 in), an overall height of 230 mm (9.1 in), and a deck rim height of 40 mm (1.6 in). These figures let countertop fabricators and installers plan the layout and confirm fit before cutting.

The drain outlet is 45 mm (1.8 in) in diameter, the standard North American size, set within a 70 mm (2.8 in) drain well. Faucet drilling configuration is confirmed per program. Full dimensional drawings, including the countertop cutout template, are available on request for specification and submittal packages.

The basin is built from glazed ceramic with a fired glaze surface that resists everyday staining and wipes clean. The non-porous glazed face keeps its finish under repeated housekeeping cycles, which supports hospitality and multifamily operators managing turnover at scale.

Glaze color and finish options are confirmed per program. For private-label and project orders, SANIKB can align finish to a buyer specification so a model stays consistent across repeat production runs.

This is a drop-in, self-rimming ceramic sink. The bowl lowers into a countertop cutout and the rim rests on the counter surface, which keeps installation fast and labor predictable for contractors and installation crews. No undermount clips or specialized mounting hardware are required.

The 45 mm (1.8 in) drain outlet accepts standard North American pop-up drain assemblies. The matching drain type is confirmed at quotation so each order ships with drain guidance aligned to the basin supplied.

SANIKB manufactures this model factory-direct and supports OEM and ODM development for brands and importers. Buyers can request modifications to dimensions, bowl profile, drilling, and finish, subject to tooling and order review, so the basin fits a target specification rather than a fixed catalog item.

As an OEM ceramic bathroom sink supplier, SANIKB also runs private label programs covering branded packaging, logo placement, and program documentation. Spec sheets, dimensional drawings, and CAD files are available to support engineering review, submittals, and your own product marketing.

This deep ceramic drop-in basin fits several B2B channels. Distributors and building materials wholesalers can stock it as a deep rectangular option for resale, while importers and trading companies can program it into container orders with export-ready packaging. Private-label brands and e-commerce resellers can list it under their own name using the complete dimensional data.

On the project side, multifamily developers and general contractors can standardize the basin across units for consistent specification and predictable installation, while hospitality FF&E buyers can specify it for guest bathrooms where the deeper bowl supports daily housekeeping. Kitchen and bath showrooms can carry it for designers and remodelers.

MOQ and unit pricing are confirmed at quotation and scaled to program volume, with tiered options available for buyers testing a model before committing to larger runs. Production lead time is confirmed per order based on quantity and customization.

Each wholesale ceramic bathroom sink order is packed in protective export packaging suited to ocean freight and port handling to help reduce breakage in transit. Samples are available on request for buyer evaluation and design sign-off, and compliance documentation is provided per program.
