The 17 inch round ceramic undermount sink is a circular lavatory basin for bathroom vanities, supplied factory-direct by SANIKB for wholesale and project channels. It mounts below the countertop, so the deck surface carries the visible edge and the basin sits underneath. The round profile fits a standard vanity and works across residential, multifamily, and hospitality bathroom layouts.

SANIKB manufactures this basin for distributors, importers, private-label brands, builders, and project buyers who need consistent specifications across repeat orders. Production runs to a single confirmed drawing, which keeps dimensions and the mounting profile stable from one purchase order to the next. Spec sheets and CAD references are available on request to support submittals and specification work.

FAQs

What are the dimensions and cutout size for this 17 inch undermount bathroom sink?

The overall outside diameter is 430 mm (17.0 in), and the bowl opening is 390 mm (15.4 in). The overall basin height, measured on the outside, is 180 mm (7.1 in), which is the exterior depth rather than the usable interior depth. The countertop cutout is based on the 390 mm (15.4 in) bowl opening, with the reveal set by the fabricator. SANIKB provides the dimensional drawing on request for templating.

Does this round ceramic bathroom sink have an overflow?

No. This round ceramic bathroom sink is supplied without an overflow, so it should be paired with a non-overflow drain, also called a free-flow drain, rather than a standard pop-up with an overflow channel. The drain opening measures 45 mm (1.8 in), with a recessed seat of 70 mm (2.8 in). Confirm drain fittings against these figures before ordering.

What material is this ceramic undermount basin made from?

The basin is made from ceramic. Finish and color options are confirmed at quotation, so buyers can align the surface to a catalog or project standard before placing an order.

How is this undermount sink installed and where does the faucet go?

It mounts below the countertop, typically with a clip or bracket system and sealant, and the rim supports against the underside of the deck. The basin has no faucet holes, so the faucet is drilled into the countertop or deck. This lets the specifier choose single-hole or widespread faucets and set their own placement.

What is the MOQ and lead time for a wholesale order?

MOQ and lead time are set per program and confirmed at quotation. Sharing your target volume and delivery schedule lets SANIKB align production and shipping to your purchase plan. Samples are available on request.

Can SANIKB supply this sink as an OEM or private-label product?

Yes. SANIKB manufactures the basin on an OEM and ODM basis, with product and packaging branding set per program. Customization scope is scoped at the RFQ stage, and private-label buyers can publish their own submittal sheets.
