    18 GAUGE SUS304

    A 10 inch undermount kitchen sink in one deep bay

    Brushed stainless over SUS304 sheet at 18 gauge (1.2 mm) is what SR3218 shows the room, and one undivided bowl is what it offers the cook. As a single bowl stainless steel kitchen sink, it trades a second bay for a full 10 inches of depth.

    The body measures 32" × 18" × 10" (813 × 457 × 254 mm) and is handmade, with sound-dampening pads and undercoating. Tight radius corners read almost square, which keeps the usable basin large and the wipe-down simple.

    Specifiers who write 10 inch undermount kitchen sink into a schedule usually mean capacity. SR3218 meets that with a 32" bay and no divider across it.

    A single bay means one waste to rough in. For a repeated unit type, the plumber and the inspector have one connection to check, not two.

    Because nothing divides the bowl, the full 32" length is one open basin.

    Eighteen inches is the body from front to back. Template the countertop from the drawing, not from the nominal cabinet size, and agree the undermount reveal with the fabricator in writing.

    CABINET IMPACT

    What a ten inch bowl takes from the cabinet

    The cabinet gives up the full 10" bowl depth before the trap even starts. Whatever lives under the sink loses that height, so plan any drawer, filter or garbage disposal against it early. Bowl depth sets how much cabinet height is left.

    For a 10 inch undermount kitchen sink, plan waste routing on the drawing and not on site. Put the trap run, the garbage disposal and the cabinet floor on one sheet and let the plumber approve it before joinery is ordered.

    Depth also decides which accessories fit. A bottom grid protects a deep base, but check it against the 18" front-to-back body first.

    Check the exterior dimensions against the cabinet. Doors, hinges and carcass sides take width from a 32" opening, so measure the clear interior width of the cabinet rather than the label on the box. Send that measurement with the RFQ and we will confirm the fit against the drawing.

    The drain opening sits to the rear of the bowl, which frees cabinet space under the sink. A cutout template and mounting clips are included for undermount installation, so the fabricator and the installer start from the same reference and the same set of parts on every unit. Confirm both on the drawing.

    ONE BAY OR TWO

    Single bay against a double bowl

    What one bay gives

    A single 32" run of basin and one drain to rough in.

    What it costs

    No divider, so separate wash and rinse zones need a second basin or a dish rack on the counter.

    Same steel, same depth

    Our double bowl codes use the same SUS304 sheet, so a mixed order reads as one family on the shelf.

    Pick by workflow

    Choose SR3218 for large cookware; choose a double when two cooks share the sink.

    DOCUMENTS

    Submittal paperwork for SR3218

    cUPC
    cUPC certified model

    SR3218 is cUPC certified. Ask for the document behind the certification so the submittal carries exactly what the factory has issued.

    Paperwork follows the model code, never a product range. Name the destination market at inquiry stage so marking and documentation are quoted against it, and ask for the drawing and spec sheet with the quotation.

    ORDERING

    Putting SR3218 on a mixed-code RFQ

    MOQ
    50 pcs
    Lead time
    30-45 days after sample approval

    Fifty pieces per code starts an order, and SR3218 can sit beside other codes from the undermount kitchen sink range on one RFQ. Write the model code and the brushed stainless finish on every PO line so a reorder reads the same way, whether it lands next month or next season, and list quantities per code so the container is loaded as planned.

    Private-label cartons, logo printing, packaging artwork and custom sizes sit inside the SANIKB OEM and ODM program. Our factory in Foshan replies to a quotation request within 12 business hours.

    • Quantity per model code
    • Cabinet width and under-bowl clearance
    • Drain position on your drawing
    • Waste, grid and accessory scope
    • Carton marking and label artwork
    • Destination port and Incoterm

    FAQs

    How deep is the SR3218 bowl, and what steel is it made from?

    Ten inches (254 mm) is the bowl depth, in SUS304 stainless steel at 18 gauge (1.2 mm) with a brushed stainless finish. The body is handmade, mounts under the counter and measures 32" × 18" × 10" overall. Check trap clearance before specifying it in a shallow cabinet, and send the cabinet height with your quotation request so we can flag any conflict.

    Is SR3218 a 10 inch undermount kitchen sink with square corners?

    It is a 10 inch deep undermount sink with tight small-radius corners that read almost square. That maximizes usable basin volume and keeps the bowl easy to wipe clean. Corner radius and size on custom orders can be discussed under our OEM/ODM service, with the drawing agreed before production starts.

    When should a buyer choose a single bowl stainless steel kitchen sink over a double?

    Choose single when large pans and large pots matter more than separate wash and rinse zones. One 32" bay is an open basin for large pans and pots, and one drain simplifies rough-in across repeated units. For divided use, compare our double bowl codes in the same stainless range.

    Does SR3218 have certification documents?

    Certification is cUPC for SR3218, and we issue documents against the model code. Tell us the destination market when you request the quotation, and we will send the drawing and spec sheet so the submittal carries the code, dimensions and material together.

    Can SR3218 be customized with low MOQ?

    Yes. Minimum order is 50 pcs per code, and we supply OEM/ODM branding, custom sizes and finishes for wholesale, builder and hospitality projects. Lead time is 30-45 days after sample approval. Send the model code, quantity and logo artwork to start.
