ONE BOWL

Single bowl undermount kitchen sink, 23 inches wide

S2318 comes in one configuration: a single bowl undermount kitchen sink in SUS304 stainless steel, 1.2 mm thick. As a stainless steel undermount prep sink it is installed beneath the counter, so the bowl rim sits under the stone.

At 23 inches wide it fits a short cabinet run, which makes it a practical undermount sink for apartment kitchen layouts and daily use.

Tight-radius corners and a brushed stainless finish give the bowl a clean outline. It suits secondary kitchens, prep stations and compact apartment layouts.

WHAT YOU CAN SPECIFY

Three decisions on an undermount single bowl sink

Bowl depth

Overall depth is 10 inches on a 23 inch wide body. The single bowl design keeps the floor area in one basin; check depth against the cabinet interior and the trap.

Steel and finish

SUS304 at 1.2 mm wall thickness, handmade, with a brushed stainless finish. A stainless steel sink in this size stays rigid for daily use.

Drain position

Ask for the model drawing so the drain position is fixed before the cabinets are built.

CABINET PLANNING

Fitting 23 inches into a short counter run

A 23 inch wide body leaves room for a drawer bank beside the sink, where a double bowl sink or any wider model would take the whole run. Check what else must share that stretch of cabinet in the kitchen layout before fixing the width, and note the cabinet size on the order.

Stone fabricators need the cutout and reveal agreed in writing. Send them the S2318 drawing early. Unlike a drop in sink, an undermount sink has its cutout edge finished at the fabrication stage, so the undermount installation is set out before the top is cut.

On a short run the waste position decides whether a bin still fits beneath the bowl, so confirm the trap layout with the plumber.

FAQs

How large is the S2318 single bowl undermount kitchen sink?

Overall size is 23" × 18" × 10" (584 × 457 × 254 mm); the installation type is undermount. The 23 inches is width, 18 inches is front to back and 10 inches is depth. Request the model drawing for cutout planning, and confirm cabinet interior width before the countertop is templated.

Is this stainless steel undermount single bowl sink suited to prep and secondary kitchens?

Yes. As a stainless steel undermount prep sink it gives a full 10 inch depth without asking for a wide cabinet. Typical uses are island prep stations, apartment kitchens with short counter runs and secondary kitchens in hotel suites or serviced residences.

What steel and finish does S2318 use?

S2318 is handmade in SUS304 stainless steel at 1.2 mm, with tight-radius corners and a brushed stainless finish. We can state the gauge on the proforma invoice so it travels with the order, and compare it with the 1.2 mm in the spec block. Ask for the model drawing if you need the corner detail.

What are the order terms for S2318 and our other kitchen sinks?

Expect a 50 pcs minimum per code. S2318 can be quoted together with other SANIKB stainless steel sinks in one enquiry. Send quantities per code and your destination port, and tell us which other sizes should sit beside S2318 in the same quotation. We send a quotation within 12 business hours of your request.

Can this undermount single bowl sink carry my own brand and cUPC paperwork?

S2318 is cUPC certified and we supply OEM and ODM branding, including own-brand cartons. Tell us the market you ship to and send artwork with your quantity, so one quotation covers the sink, the documents and the packing for your market.
