    BRUSHED SUS304

    Double stainless steel sink with a 20-inch body

    Front-to-back depth is the design detail on D3320. The body measures 20 inches from front to back, which is the dimension a buyer has to check before ordering a double bowl kitchen sink in this class.

    Stainless steel undermount kitchen sink, 33x20 — SANIKB D3320

    Brushed stainless

    18 gauge (1.2 mm), brushed stainless

    Handmade undermount construction in SUS304 stainless steel, with a protective undercoating on the underside.

    WIDE OFFSET

    Offset bowls across 33 inches of width

    Offset divider

    In this double bowl kitchen layout the two bowls are unequal. One basin takes the bulk of the washing and the other stays free for rinsing.

    Extra front-to-back room

    At 20 inches, the body is deeper than a 19-inch sink of the same width, so check counter depth and cutout together.

    Sound control

    Dampening pads and protective undercoating reduce noise, which helps in cabinets that also hold a disposer or dishwasher.

    Compare other widths and bowl splits in our stainless steel kitchen sinks range.

    ROOM PLANNING

    Double bowl kitchen sink: counter depth and cutout reveal

    Start with the counter. A 20-inch body is easy to mis-order against a cutout drawn for a 19-inch sink, so attach the D3320 drawing when the fabricator prepares the template.

    Check three things on site: rear faucet space behind the bowls, the cutout and reveal at the stone edge, and the cabinet clear opening with its mounting supports. Both waste assemblies must clear the cabinet floor and any shelf.

    The extra front-to-back size does not by itself prove a larger usable bowl. Compare the real bowl openings on the drawing against the alternative you are replacing, then confirm drain positions for each outlet.

    FAQs

    Is D3320 a double stainless steel sink for deep counters?

    It suits counters that can take a 20-inch front-to-back body. Overall size is 33" × 20" × 10" (838 × 508 × 254 mm), brushed SUS304 stainless steel at 18 gauge (1.2 mm). Confirm the countertop depth and the cutout against the drawing before ordering, since a cutout drawn for 19 inches will not match.

    How does the 20-inch body compare with a 19-inch double bowl undermount kitchen sink?

    Outer front-to-back size is one inch larger, yet bowl area still has to be measured. Use the D3320 drawing to compare the bowl openings, drain positions and countertop layout with the 19-inch model you are considering, then decide on the real working area.

    What should be checked before approving fabrication?

    Check rear faucet space, cutout and reveal, the cabinet clear opening and the mounting supports. Confirm both waste assemblies as well. Because D3320 has two offset bowls, each outlet sits in a different position, so the trap run must be planned from the model drawing.

    Is sound dampening included for wholesale orders?

    Yes. Rubber dampening pads go on every sink, and the undercoating reduces noise further. The specification can also be customised for OEM and ODM project supply, with a minimum order of 50 pcs. Send drawings and a target quantity together, and we quote against them with the divider position and packaging you need.

    What are the lead time and documents for D3320?

    Standard lead time is 30-45 days after sample approval. D3320 is cUPC certified, and we send the spec sheet and a dimensioned drawing with the quotation. State the destination market in the RFQ so the paperwork matches it, and name the quantity per code on each line.
