Zero Radius, 33 × 19.5

Square inside corners on a 33 by 19.5 body

Zero radius is a look before it is anything else. This undermount stainless steel sink single bowl carries square inside corners on a 33 by 19.5 inch body, 9 inches deep.

01 / CORNERS

Corners are the specification

The title records zero radius. Put that wording in the schedule so a softer corner is not substituted at site.

02 / BODY

19.5 inches front to back

Nineteen and a half inches into the cabinet at a 9 inch depth. Both figures go to the cabinet maker before the carcass is built.

Softer corner options are in the undermount kitchen sink collection.

Fit & Clearance

Nineteen and a half inches into the cabinet

Nineteen and a half inches is the figure to check, not the width. Full set is 33 by 19.5 by 9 inches, 838 by 495 by 228.6 mm.

Overall Size 33" × 19.5" × 9" (838 × 495 × 228.6 mm)
Mounting Undermount
Bowl Single, zero radius
Listed Depth 9" (228.6 mm)

The extra front to back dimension is checked against the carcass and the counter overhang together. A 33 inch cabinet run does not automatically take it.

Ask for the drawing with the drain centre and the corner radius dimensioned so the fabricator templates once.

Zero radius corners need the reveal agreed in writing with the fabricator.

Construction & Finish

SUS304, 18 gauge, brushed, square corners

Corner geometry does not change the material line. SUS304, 18 gauge, 1.2 mm, brushed stainless.

BRUSHED

Shape and finish are separate lines

Zero radius is a shape and brushed stainless is a finish. Write both on the order, because substituting either one changes what arrives.

The record lists a handmade undermount type. How the square corners are produced is not described, so it does not go on a submittal.

Corner description and finish name both belong on the PO line.

Compliance

Design language is not a compliance claim

DOC
Drawing issued per model code

Ask for it with the spec sheet at RFQ, so the corner detail is on paper before the counter is templated.

Nothing is listed against S3319 in the way of an approval scheme. A design feature does not stand in for documentation.

Give the destination market at enquiry and the documentation is quoted to it.

Procurement

Showroom display and the order behind it

SANIKB is the factory, so a display piece and a production run share one specification.

Published MOQ 50 pcs
Standard Lead Time 30–45 days after sample approval

Design led codes usually start on a display before they sell. Several codes can sit on one order, so a display unit ships with the working quantity.

Display packing and own label cartons for a design led code are arranged with the SANIKB OEM and ODM programme. A quotation comes back within 12 hours.

Include these details with the RFQ

  • Quantity by model code
  • Corner radius written into the schedule
  • Cabinet interior depth available
  • Waste and accessory scope
  • Carton marking and artwork
  • Destination port and Incoterm
  • Target shipment date

50 pcs is the MOQ here. Confirm at quote how a display piece is counted.

FAQs

What makes this a zero-radius sink?

The basin is welded with tight near-zero-radius square corners and crisp vertical walls for a modern look and maximum 33 × 19.5 in. interior washing area.

Why is this bowl shallower at 9 inches?

At 33 × 19.5 × 9 in. (838 × 495 × 229 mm) the flat-bottom bowl trades a little depth for a wider, ergonomic basin that is easier on the back during long prep.

Can square-corner sinks be customized for trade orders?

Yes. We fabricate zero-radius stainless steel kitchen sinks in custom sizes and tap-hole layouts with OEM/ODM service and low MOQ for project buyers.
