Shallow 170 mm Bowl

A shallow 6.7 inch bowl for slim vanity tops

SN019 is an undermount basin listed at 6.7 inches on the depth line. Shallow bodies are specified where the cabinet below has to keep its drawers.

01 / DEPTH

170 mm on the depth line

That depth leaves room for a drawer under the counter instead of a cupboard. It is a cabinet decision more than a basin decision.

02 / OVERFLOW

Overflow named in the title

The title lists an overflow. Ask for the drawing showing its position before the counter is drilled or the waste is chosen.

Shallow bodies sell to vanity makers rather than to plumbers, which is worth remembering across the undermount ceramic sink range.

Fit & Clearance

Cutout planning for a 520 by 355 mm basin

Size is listed as 520 by 355 mm on plan, with the bowl running 170 mm deep.

Overall Size 20.5" x 14.0" x 6.7" (520 x 355 x 170 mm)
Mounting Undermount
Finish Glossy White
Published MOQ 20 pcs

An undermount ceramic basin is set to a template and supported from below. Ask how the factory expects it to be supported and get that onto the drawing.

Nothing here describes the fixing method or what is supplied with the basin. Confirm both before the counter shop quotes the job.

Send the cutout drawing to the stone shop before the top is cut.

Construction & Finish

Glossy white china on an undermount body

An undermount basin is bought together with the top it sits under. The record covers only the basin: vitreous china, glossy white.

Glossy White

One finish on the record

Glossy white is the only finish published for this model. A matte or coloured version would be a development item rather than a catalogue choice.

Undermount ceramic is usually specified alongside a stone or engineered top. Keep the material description on your quote identical to the record so the two documents agree.

Ask the factory to confirm anything the specification does not state.

Compliance

Records a buyer keeps for undermount china

DOC
The drawing is the working document

Ask for a dimensioned cutout drawing with the quotation. It is the sheet the fabricator actually uses on site.

No approval scheme or test mark is named in this specification. The page records material, size, mounting and finish.

For undermount work the drawing usually matters more than any brochure. Agree at RFQ which documents follow the goods into your market.

Procurement

Twenty pieces inside a mixed bathroom order

The order conversation on an undermount basin starts with the top it goes under, not with the basin.

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

A twenty piece minimum suits a vanity maker testing a shallow basin against one cabinet line. It is small enough to prove the fit before scaling.

Vanity makers who need a different bowl depth or a private label carton should start with the SANIKB OEM and ODM program.

Include these details with the RFQ

  • Quantity for this model
  • Cabinet line it is being matched to
  • Cutout drawing and overflow position
  • Fixing method and what is supplied
  • Destination port and Incoterm
  • Carton and pallet arrangement
  • Requested delivery date

Confirm the overflow and fixing details in writing before the first order ships.

FAQs

What are the dimensions of this shallow rectangular ceramic undermount sink?

The basin measures 520 mm by 355 mm (20.5 in by 14.0 in) overall, with an interior bowl opening of 470 mm by 300 mm (18.5 in by 11.8 in) and an overall exterior height of 170 mm (6.7 in). Full dimensioned drawings are available on request.

How does the undermount installation work for this rectangular ceramic basin?

The basin mounts beneath the countertop using its flat mounting rim as the mounting and sealing surface, leaving a recessed edge below the counter cutout. Request the cutout template and mounting detail to size the opening and reveal before cutting.

What drain does this ceramic undermount bathroom sink require?

The basin is dimensioned for a Ø70 mm (Ø2.8 in) and Ø45 mm (Ø1.8 in) drain detail. Because the bowl is configured without an overflow, it pairs with a non-overflow free-flow drain rather than a standard pop-up with overflow.

What ceramic finish and color options are available for this undermount vanity basin?

The basin is formed in ceramic with a smooth, wipe-clean surface. Finish and color options are confirmed at quotation and can be matched to your program for branded or specified orders.

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

Yes. SANIKB supports OEM, ODM, and private-label production, including finish, branding, and packaging configured to your program, with dimensional or tooling adjustments scoped at the RFQ stage.

What is the MOQ, lead time, and sample policy for this wholesale rectangular ceramic sink?

Samples are available on request for evaluation. MOQ, lead time, and pricing are confirmed at quotation based on order volume and destination. Send your project specifications to receive a tailored quote.
