D3318 double bowl undermount kitchen sink: 33 by 18 inches

Next to a 20 inch body, D3318 takes two inches off the front-to-back run. It keeps a 33 inch width and 10 inch depth, which makes it a narrow 33 by 18 inch double bowl undermount stainless steel sink with 10 inch depth, D3318, for tighter cabinets.

Model: D3318
Overall size: 33" × 18" × 10" (838 × 457 × 254 mm)
Layout: Double bowl
Mount: Undermount
Material: SUS304 stainless steel, 18 gauge (1.2 mm)
Finish: Brushed stainless

Width and depth stay at 33 and 10 inches, so the cabinet opening changes mainly in the front-to-back direction.

SLIM BODY

How an 18 inch body changes the counter layout

Those two inches go back to the counter, mostly behind the bowls.

On a narrow counter that saving leaves more room for the tap base and any soap dispenser. Set both out on the drawing before the worktop is cut.

Two bowls share one 33 inch body, and double bowl sinks of this size need both drains placed before the trap is chosen. Plan where the divider and both drains fall before the trap and any waste disposer are chosen.

PROJECT FIT

Where a narrow double bowl gets specified

Shallow cabinets

Where the cabinet is shallower than a 20 inch body allows, an 18 inch body may avoid a custom cabinet change.

Galley kitchens

A narrow body leaves more of the counter free behind the sink for the tap and a dispenser.

Hotel and multifamily

Keep one 33 inch width across unit types and choose the depth per plan.

FAQs

Which double bowl sinks suit a counter too shallow for a 20 inch body?

D3318 is the 18 inch option when a 20 inch double bowl will not fit the cabinet. It keeps the 33 inch width and 10 inch overall depth, so the cutout changes mainly front to back. Check rear clearance for the tap and any wall upstand on the drawing before the worktop is cut.

What are the overall dimensions of the narrow 33 by 18 inch double bowl undermount stainless steel sink with 10 inch depth, D3318?

Overall size is 33" × 18" × 10" (838 × 457 × 254 mm). The 18 inches is the front-to-back dimension of the sink body and 10 inches is its overall depth. For bowl-by-bowl dimensions, request the model drawing together with your quotation.

What material and finish does D3318 use?

D3318 is handmade in SUS304 stainless steel, 18 gauge (1.2 mm), with a brushed stainless finish. Ask us to restate the gauge on the proforma invoice so it travels with the order. The 10 inch depth is part of the overall size; confirm each bowl's depth on the model drawing.

Can I combine D3318 with other double bowl sinks in one order?

MOQ is 50 pcs. D3318 can be quoted next to our larger double bowl codes in one enquiry. Typical lead time is 30-45 days. Send the quantity per code and your destination port, and we will confirm the quotation and shipment plan for you.

Is a cUPC document available for this double bowl undermount kitchen sink?

D3318 is cUPC certified, and we supply the document set with the order. Tell us the market you ship to when you enquire, so marking and carton text fit it. OEM and ODM branding can be added through our service page, and we confirm the details in the same quotation.
