FAQs

Does the elongated oval ceramic undermount sink have an overflow?

No. This basin has no overflow and is designed for a non-overflow, free-flow drain. Pairing it with a standard overflow pop-up leaves the overflow port unused and can affect drainage, so specify a free-flow drain to match.

What are the dimensions of this undermount bathroom basin?

The basin is 578 × 385 mm (22.8 × 15.2 in) overall, with a 518 × 325 mm (20.4 × 12.8 in) bowl opening and a 200 mm (7.9 in) overall depth to the bowl exterior. The rim is about 30 mm (1.2 in) wide and the edge is 13 mm (0.5 in) thick.

What size drain does the oval ceramic undermount basin use?

The drain opening is Ø45 mm (1.8 in) with a Ø70 mm (2.8 in) seat recess and accepts standard lavatory drain fittings. Because the basin has no overflow, the fitting should be a free-flow type.

Does the basin come with faucet holes?

No. As an undermount basin, it has no faucet holes. The faucet is drilled in the countertop deck or mounted on the wall, which supports single-hole, widespread, or wall-mounted layouts.

What countertop cutout and reveal options does the oval undermount lavatory support?

The basin supports positive, flush, and negative reveals. Set the countertop cutout from the basin's cutout template and your chosen reveal rather than from the bowl opening, since the reveal changes the final cut.

Can the ceramic undermount vanity sink be supplied under our own brand?

Yes. SANIKB supports OEM, ODM, and private-label programs, including custom dimensions, finish, color, packaging, and rebrandable spec sheets. Minimum order quantity, lead time, and pricing are confirmed at the quotation stage.
