30 × 18, Small Radius

Small radius corners on a 30 inch bowl

Corner radius is the visible difference between one under mount stainless steel sink and the next. S3018 is recorded with small radius corners on a 30 by 18 inch body.

01 / CORNERS

Softened, not square

Small radius is what the title carries. It is a different corner from a zero radius bowl and it should be written that way in the schedule.

02 / BODY

Thirty inches wide, ten deep

Thirty inches across at 10 inches down, 762 by 254 mm on the record. That is the width a standard cabinet run is drawn around, and where a dealer range starts.

The sharper and wider bodies sit alongside it in the undermount kitchen sink range.

Fit & Clearance

Rough-in on a 30 inch single bowl

Thirty inches of bowl asks for more than a thirty inch cabinet. Record is 30 by 18 by 10 inches, 762 by 457 by 254 mm.

Overall Size 30" × 18" × 10" (762 × 457 × 254 mm)
Mounting Undermount
Bowl Single, small radius
Listed Depth 10" (254 mm)

The bowl is 30 inches. The cabinet has to be wider than that and the fabricator needs the reveal on both sides, so confirm the carcass before the counter is templated.

The drawing carries the drain centre. Get it before the waste and any disposal unit the end user plans are roughed in.

Corner radius is described in the title. Get it dimensioned on the drawing.

Construction & Finish

The finish behind a volume listing

Volume does not buy a different material spec. S3018 carries SUS304, 18 gauge, 1.2 mm, brushed stainless, the same as the rest of the range.

SUS304

The finish a dealer photographs

Brushed stainless is what is published, and on a volume code it is also what the catalogue image has to match. Sign it off on a physical sample before the shoot.

The type line records a handmade undermount sink and stops there. Nothing further about the build goes on a submittal until the factory confirms it.

A private label finish request is quoted at RFQ rather than assumed from the catalogue.

Compliance

A volume code carries no implied mark

DOC
Drawing and spec sheet per code

Both are issued against S3018 on request. Ask at RFQ rather than after the container is booked.

No approval scheme is recorded for S3018. Volume does not change that, and nothing is claimed on the strength of it.

Give the destination market with the enquiry so testing and marking are quoted against the right rules.

Procurement

The size a dealer commits shelf space to

SANIKB manufactures it, so a programme order is set up around your own labelling.

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

A volume code carries the private label work. Printed logo, carton artwork and insert design run through the SANIKB OEM and ODM programme, and a quotation follows within 12 hours.

More than one code can go on the same order. A dealer range built around this size still ships as one PO and one inspection.

Include these details with the RFQ

  • Quantity by model code
  • Cabinet width you are matching
  • Corner radius dimensioned on the drawing
  • Waste and accessory scope
  • Carton marking and artwork
  • Destination port and Incoterm
  • Target shipment date

50 pcs is the MOQ on this code, private label included.

FAQs

What gauge and steel grade is this sink made from?

It is fabricated from SUS304 stainless steel in an 18-gauge (1.2 mm) body for rigidity and corrosion resistance, finished in a brushed satin surface that hides everyday scratches.

What are the inside corners like for cleaning?

This 30×18×10 in. bowl uses tight small-radius rounded corners that maximize usable basin space while staying easy to wipe down, unlike sharp zero-radius wells.

Can we order custom sizes and low MOQ for a project?

Yes. As a direct manufacturer of stainless steel kitchen sinks we offer OEM/ODM, custom cabinet sizing, sound-dampening pads and low MOQ for distributor and project orders.
