25 × 20, Six Deep

A wide mouth over a six inch well

Depth is the whole decision on this one. Among stainless steel kitchen undermount sinks 25 inch wide, a 6 inch bowl is a deliberate choice rather than a shortfall.

01 / DEPTH

Six inches, published

The record lists 6 inches, 153 mm. Everything under the counter gains that space back, which is the reason to specify it.

02 / MOUTH

Twenty five by twenty at the rim

The opening stays large while the well stays shallow. Check both numbers against the counter and the cabinet before it is scheduled.

Standard depths on the same footprint sit in the undermount kitchen sink range.

Fit & Clearance

What a shallow bowl changes underneath

Six inches is the number buyers query first. It is published, alongside 25 by 20 at the rim, 635 by 508 by 153 mm.

Overall Size 25" × 20" × 6" (635 × 508 × 153 mm)
Mounting Undermount
Bowl Single
Listed Depth 6" (153 mm)

Waste routing, a drawer bank and anything else in the cabinet all sit against the 6 inch figure. Check it on the drawing before the cabinet package is approved.

The rim is 25 by 20 inches. That is the figure the counter fabricator works to, and the reveal is agreed with them in writing.

Do not size the cabinet from the depth alone. Both figures matter.

Construction & Finish

SUS304 at 18 gauge on a shallow body

The shallow body sits on the same material record as the deep ones: SUS304, 18 gauge, 1.2 mm.

18 GAUGE

Gauge is recorded, behaviour is not

1.2 mm at 18 gauge is published. How a shallow bowl behaves in service is not, so nothing of that kind is written here.

The type line says handmade undermount and goes no further. Construction detail is confirmed in writing before it reaches a submittal.

Any finish other than the published brushed stainless is an OEM request and is sampled first.

Compliance

The record is the limit of what we claim

DOC
Spec sheet on request

Issued against the model code with the drawing, so the 6 inch depth is documented rather than described.

No approval scheme appears against S2520. It is not implied on a submittal or on a quotation.

Destination market decides the documentation. Say which one and it is answered with the quote.

Procurement

A specialist depth still buys like a run

The factory quotes specials next to the standard bodies.

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

Shallow bowls are usually a small share of a schedule. Several codes can sit on one order, so the special does not travel on its own.

A special depth can still carry your own carton and printed artwork, set up through the SANIKB OEM and ODM programme. A quotation is issued within 12 hours.

Include these details with the RFQ

  • Quantity by model code
  • Bowl depth confirmed on the drawing
  • What sits in the cabinet below
  • Waste routing and accessory scope
  • Carton marking and artwork
  • Destination port and Incoterm
  • Target shipment date

The 50 pcs MOQ applies to this code the same as to a standard body.

FAQs

What gauge stainless steel is this prep sink made from?

It is fabricated from SUS304 18-gauge (1.2 mm) stainless steel for corrosion resistance and durable daily use across our shallow single bowl undermount prep sink line.

Why is this prep bowl only 6 inches deep?

The shallow 6" depth makes it a dedicated prep and secondary station, ideal for rinsing produce or pairing beside a main sink in islands and bar areas without crowding under-cabinet plumbing.

Can the size and corner radius be customized for projects?

Yes. As an OEM/ODM manufacturer we adjust outer dimensions, bowl depth, and corner radius, and we accept low MOQ for distributor, builder, and hospitality projects.
