Rounded Corner, 9.3 Deep

Rounded corners put the radius figure on the drawing

SR3218B is the rounded corner 32. It is a stainless steel single bowl undermount kitchen sink that gets its own drawing, because a radius does not template like a square corner.

01 / RADIUS

The radius belongs on the drawing

The record names rounded corners but gives no radius figure. Get that number issued before anyone cuts a template.

02 / BODY

Not a swap for SR3218

SR3218B is 18.2 inches front to back against 18 inches on SR3218. Two tenths matters to a template, so the codes are specified separately.

The rest of the undermount bodies on this steel sit in the undermount kitchen sink range.

Fit & Clearance

Templating a 32 by 18.2 inch body

The template runs off 18.2 inches front to back and a 9.3 inch bowl. Overall 32 by 18.2 by 9.3 inches, 813 by 463 by 236 mm.

Overall Size 32" x 18.2" x 9.3" (813 x 463 x 236 mm)
Corner Rounded
Listed Depth 9.3" (236 mm)
Mounting Undermount

At the same 32 inch width the bowl is 9.3 inches against 10 inches on SR3218. That matters when the trap run under the cabinet is tight.

A radius cut and a square cut are not one template. Send the drawing for the code shipping.

Ask for the radius figure in writing with the drawing.

Construction & Finish

SUS304 at 1.2 mm with a brushed stainless finish

One steel and one finish are published against SR3218B: SUS304 at 18 gauge, 1.2 mm, in brushed stainless.

18 GAUGE

One finish published on this body

Brushed stainless is the only finish published against SR3218B. If a programme needs another finish on this body, raise it in the enquiry so it can be confirmed at sample stage.

Type is recorded as a handmade undermount sink, and nothing in the record says how the corner is produced. That stays off the submittal until the factory confirms it.

Name SR3218B on its own PO line, separate from the square corner codes.

Compliance

Destination market first, documents second

DOC
Drawing first, submittal second

Ask for the drawing and spec sheet with the RFQ. On a radius corner sink both fabricator and specifier work from it.

Documentation follows the market. Tell us the destination port in the enquiry.

No approval scheme is recorded for SR3218B. Any mark a buyer needs is issued for this code, not inherited from another SR size.

Procurement

Where SR3218B fits in a mixed size order

A quote here runs across sizes rather than one line at a time.

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

SR3218 holds the same 32 inch width with a square corner and a 10 inch bowl, so the two codes quote together on one RFQ while templating separately. Split the quantities by code on the enquiry.

The SANIKB OEM and ODM programme covers own brand cartons, logo printing and custom sizes. Spec sheet on request. Enquiries answered within 12 hours.

Include these details with the RFQ

  • Quantity per code and corner type
  • Radius figure to confirm
  • Counter material and fabricator
  • Waste and accessory scope
  • Private label carton artwork
  • Destination market, port and incoterm

SR3218B and SR3218 are separate codes, so the 50 piece MOQ applies to each.

FAQs

What material and bowl depth does this sink use?

This rounded corner single bowl undermount kitchen sink is fabricated from SUS304 18-gauge (1.2 mm) stainless steel with a 9.3-inch (236 mm) bowl that suits standard base cabinets.

How do the rounded corners differ from a zero-radius bowl?

The generous radius corners are quicker to clean than tight square corners and give the basin a softer look while keeping full usable width at 32 inches.

Do you offer custom sizes, OEM/ODM, and low MOQ?

Yes. We provide OEM/ODM branding, custom sizes and finishes, and low MOQ project supply direct from the factory for distributors and contractors.
