SN036 Compact Round Ceramic Undermount Basin

This basin has no overflow, so it pairs with an unslotted, non-overflow waste rather than a standard pop-up built for an overflow basin. A free-flow grid drain or an unslotted click-clack drain fits the 45 mm (1.8 in) outlet and its 70 mm (2.8 in) seat at the base of the bowl. The distinction matters, since a slotted pop-up made for an overflow basin will not seat or seal correctly here. Drain compatibility and whether a drain ships with the basin are confirmed at quotation.

Installing this ceramic undermount bathroom sink starts with a countertop cutout matched to the basin template. Fabricators set the rim with a positive, negative, or flush reveal depending on the project detail. The basin mounts beneath stone, quartz, or solid-surface tops using clips, brackets, or adhesive support rated for the basin weight, with the rim flange seated against the underside of the counter. Ceramic is a heavy material, so the supporting structure and counter should be specified for the load.

As a round undermount basin for small vanities, the compact 400 mm (15.8 in) footprint fits applications where deck space is limited. It works in multifamily unit bathrooms, hotel guest and powder rooms, and floating or shallow vanities where a smaller bowl keeps the layout open. Procurement buyers specify it across phased developments and property rollouts where the same model has to be reordered over time. Distributors and showroom dealers stock it as a compact ceramic option for contractors and designers, while private-label brands position it within their own bathroom lines.

SANIKB manufactures this OEM ceramic undermount basin factory-direct, which gives buyers room to customize beyond the standard model. Custom dimensions, glaze color, and finish are scoped at quotation against program volume and tooling. OEM and ODM buyers can integrate the basin into an existing line, with technical data provided for catalog use. SANIKB also supports private-label programs for brands that need the basin supplied under their own name. Customization scope, minimums, and tooling are confirmed during the RFQ process rather than fixed in advance.

Buyers evaluating this wholesale round undermount basin can request samples to check glaze, color, and finish before committing to volume. SANIKB supports export packaging for ceramic basins, with specifics matched to the order, freight method, and destination at the RFQ stage. Pricing and program terms are quoted through the same process. Request OEM pricing or send us your project specs to start the quotation.
