GLOSSY WHITE CHINA

Rectangular undermount bathroom sink in glossy white china

Vitreous china in glossy white, cut as a shallow rectangular ceramic undermount basin 520 x 355 mm, with a body only 6.7 inches (170 mm) tall.

Shallow bodies matter when the cabinet below has drawers, because every millimetre of basin height is a millimetre taken from the drawer box.

Installation is beneath the countertop. The flat mounting rim acts as the sealing surface, leaving a recessed edge under the cutout. Ask for the cutout template and mounting detail before the stone is cut.

BOWL AND DRAIN

Overflow, drain bodies and surface of SN019

Overflow built in

SN019 has an overflow, so specify an overflow-compatible basin drain rather than a free-flow one.

Two drain diameters

Both Ø70 mm and Ø45 mm figures appear on the drawing, so order the waste hardware against it.

Smooth ceramic surface

Formed in ceramic with a smooth, wipe-clean surface.

Finish by program

Finish and color options beyond glossy white are confirmed at quotation for branded or specified orders.

DOCUMENTS

cUPC certification and drawings for submittals

cUPC

cUPC certified basin

SN019 carries cUPC certification. Ask at RFQ which documents should travel with the goods into your market.

Contractors and distributors can ask for the dimensioned drawing, cutout template and certification paperwork together with the quotation.

Samples are available on request, so a vanity maker can test the shallow profile against a real cabinet before committing a volume of undermount sinks.

WHOLESALE

Twenty pieces and a 30-45 day typical lead time

MOQ: 20 pcs
Standard Lead Time: 30-45 days (typical)

A twenty-piece minimum suits a vanity maker proving one cabinet line with undermount sinks. A different bowl depth or private-label carton goes through the SANIKB OEM and ODM program.

FAQs

What are the dimensions of this shallow rectangular ceramic undermount basin 520 x 355 mm?

It measures 520 × 355 mm (20.5 × 14.0 inches) overall, with an interior bowl opening of 470 × 300 mm (18.5 × 11.8 inches) and an exterior height of 170 mm (6.7 inches). Full dimensioned drawings are available on request, and the cutout should be taken from them.

How is this rectangular undermount bathroom sink installed?

It mounts beneath the countertop, using the flat mounting rim as the sealing surface and leaving a recessed edge below the cutout. Request the cutout template and mounting detail to size the opening and reveal before cutting. Share them with the stone fabricator at the same time as the order.

Which drain suits SN019?

SN019 has an overflow, so choose an overflow-compatible basin drain. The drawing shows Ø70 mm (Ø2.8 inches) and Ø45 mm (Ø1.8 inches) drain details. Match the drain body, flange and seals to that drawing and confirm the fittings before the first order is placed.

Do you offer OEM and private label for this ceramic undermount sink?

Yes. SANIKB supports OEM, ODM and private-label production, including finish, branding and packaging configured to your program. Dimensional or tooling adjustments are scoped at the RFQ stage. Send your drawings and logo files, and we reply to quotation requests within 12 business hours.

What are the MOQ, lead time and sample terms?

MOQ is 20 pcs, with a typical lead time of 30-45 days. Samples are available on request for evaluation, so a cabinet maker can check the 6.7 inch height first. Send project specifications and destination to receive a quote for the order volume.
