33 BY 19.5

Zero radius, 33 × 19.5 × 9 single bowl

Square inside corners define this zero radius single bowl undermount kitchen sink. Looking for an undermount stainless steel sink single bowl with square corners? S3319 is 33 inches wide, 19.5 inches front to back and 9 inches deep. As an undermount sink it is installed beneath the countertop. Choose this kitchen sink when the cabinet has the depth and cleaner geometry matters.

Model: S3319
Overall size: 33" × 19.5" × 9" (838 × 495 × 228.6 mm)
Layout: Single bowl, zero radius
Mount: Undermount
Material: SUS304 stainless steel, 18 gauge (1.2 mm)
Finish: Brushed stainless
Build: Handmade

Front-to-back is 19.5 inches, 495 mm. Check carcass depth and counter overhang together before ordering.

SQUARE CORNERS

What zero radius means on a welded bowl

Interior corners are square, not rounded. Walls rise straight from a flat-bottom bowl, which gives a sharp, architectural outline and the most usable floor area for the 33 by 19.5 inch footprint.

Squared corners also change the template, and unlike a drop in sink, an undermount sink needs the cutout edge finished to the drawing. Put the words zero radius on the schedule so a softer-cornered sink is not substituted on site.

A 9 inch depth trades some height for a wider, flatter basin. Large trays lie flat and the bowl is shallower to reach into during long prep sessions. Where tall stockpots are the main load, compare it with deeper models.

Square corners leave no radius for a cabinet maker to cut around, so the template must match the bowl exactly. Request the model drawing before the countertop is cut, and confirm the cutout against it.

PROJECT FIT

Where this single bowl kitchen sink gets specified

Show homes

Crisp corners look sharp in display, which suits model kitchens and marketing suites.

Chef-style residences

A wide, flat basin has room for large trays and daily use in a busy kitchen sink position.

Light commercial prep

Hotel pantries and staff kitchens get one large basin without a divider, where a double bowl sink would split the working width.

Custom tap holes

Tap-hole layouts can be adjusted for project orders. Send the faucet model with your drawing.

FAQs

What makes S3319 a zero radius undermount sink and kitchen sink?

Its bowl is welded with tight, near-zero radius square corners and straight walls. That gives a crisp modern outline and maximum floor area inside a 33 × 19.5 inch footprint. Write zero radius into your schedule so a rounded-corner sink is not substituted at site, and keep the model code on every purchase order line.

Why is the bowl 9 inches deep?

At 33" × 19.5" × 9" (838 × 495 × 228.6 mm) the flat-bottom bowl trades a little depth for a wider, easier-to-reach basin. That suits long prep sessions and large trays. If you need more height, compare our deeper models. Send the cabinet height if you want us to check the bowl against it.

Which cabinets suit an undermount stainless steel sink single bowl like S3319? Installation type is undermount.

S3319 suits runs where a shallower front-to-back body is too tight and the cabinet can take 19.5 inches. Overall width is 33 inches. Always confirm the carcass, rails and reveal against the model drawing before ordering countertops, and ask us for that drawing with your quote. Check cabinet depth first, because 19.5 inches is the figure that decides fit.

Can square-corner sinks be customised for trade orders?

Yes. We fabricate zero radius stainless sinks with custom sizes and tap-hole layouts through OEM and ODM service. Send your drawing and quantity, and the quotation covers dimensions, drilling and carton marking in a single reply from our factory. Tell us the faucet model and the number of tap holes so the layout is drawn correctly.

What are the MOQ and certification for this kitchen sink?

S3319 carries cUPC certification and ships from 50 pcs. It is SUS304 at 18 gauge (1.2 mm) with a brushed stainless finish. Send quantities per code and your destination port for a quotation, together with any custom tap-hole layout. The certificate and the drawing can be requested together.
