Rounded Corner Bowl

Rounded corners on a 32 by 18 inch single bowl

S3218 is described in its title as a rounded corner sink. The corner treatment is the difference a customer notices first, so it is worth confirming on paper.

01 / CORNERS

Corner shape from the listing

The title describes the corners as rounded. Request the dimensioned drawing before you repeat that in a tender or a submittal.

02 / BODY

812.7 by 457.2 mm on plan

Published depth is 254 mm. The proportions read as a standard full size single bowl in most kitchen layouts.

Corner style is the usual tie breaker between two similar sizes, and both styles sit in the undermount kitchen sink range.

Fit & Clearance

Reading the 32 by 18 footprint before templating

The record carries decimals here: 812.7 by 457.2 mm, with depth listed at 254 mm.

Overall Size 32" x 18" x 10" (812.7 x 457.2 x 254 mm)
Mounting Undermount
Listed Depth 10" (254 mm)
Finish Brushed stainless

The published figures carry a decimal for a reason. Use them as given when the counter is cut, rather than rounding to the nearest inch.

Drain position and any tap ledge are not covered on this page. Both should be settled on the drawing.

Ask the fabricator to work from the millimetre figures if they cut metric.

Construction & Finish

Where 18 gauge sits on a material submittal

Thickness is given twice, as 18 gauge and as 1.2 mm. Neither figure says where on the body it was taken.

1.2 mm

State the measurement point

A thickness figure means more when everyone agrees where it is measured. Ask the factory to confirm that point in writing if your inspector checks it.

Finish is recorded as brushed stainless. Keep that exact wording on your own documents so the description on the goods matches the description on the order.

One description should carry across drawing, order and invoice without edits.

Compliance

Approval paperwork against catalogue description

DOC
Separate description from evidence

Treat catalogue wording and third party evidence as two different things. Only the second one belongs in a submittal.

This listing describes a product. It does not record an approval, and no scheme is named anywhere in the specification.

Where a project asks for evidence, that evidence is scoped from the destination market. Raise it at RFQ so it is prepared with the order.

Procurement

Quoting a 32 inch single bowl in project volume

Phasing is the part buyers forget to state, and it changes a quotation more than the quantity does.

Published MOQ 50 pcs
Standard Lead Time 30-45 days (typical)

Project buyers usually need one size repeated many times with the same corner detail. Confirm that the repeat units are quoted against the same drawing.

Repeat project items can be locked to your own drawing through the SANIKB OEM and ODM program.

Include these details with the RFQ

  • Units required and phasing
  • Drawing reference for the repeat order
  • Destination port and Incoterm
  • Confirmed corner detail
  • Finish and marking
  • Packing arrangement for site delivery
  • Required delivery dates

Phased projects should be quoted as one order with staged shipping dates.
