    60/40 DOUBLE

    FD3321: a 33 inch farmhouse sink with unequal bowls

    FS3321 puts one single bowl into a 33 x 21 x 10 inch body. FD3321 keeps that footprint and divides it into a double bowl sink, which makes it the stainless steel country kitchen sink for kitchens that wash and rinse at the same time.

    The larger bowl takes the heavy work

    The bigger side of the 60/40 split holds roasting pans and stockpots. The smaller side stays free for rinsing and draining.

    The disposer goes under one side only

    Decide which bowl carries the garbage disposal before the trap is set out. That choice fixes the waste position on the drawing, and each bowl has its own drain opening.

    A bowed apron instead of a flat panel

    A bowed front is the styling difference from flat-apron bodies. Buyers who want a flat face should compare the single bowl models in the range.

    More apron-front styles, from single bowl to double, sit in our farmhouse sink collection.

    SPECIFICATION

    Build and size of this 33 inch farmhouse sink

    Size, gauge and finish for this 33 inch farmhouse sink in one table.

    Model
    FD3321

    Material
    SUS304 stainless steel, 18 gauge (1.2 mm)
    Finish

    MOQ

    Both bowls share a 10 inch (254 mm) depth, inside a body 33 inches wide and 21 inches front to back.

    CABINET FIT

    Cabinet size for a double apron sink: 36 inch base

    Two deep bowls need a cabinet that can carry them. The minimum cabinet size for FD3321 is a 36 inch sink base with the apron cutout made in the front rail.

    The curved apron sits slightly proud of the cabinet face. Check the reveal against the door line during templating, not after the stone is cut.

    Waste centres differ on a divided sink. Tell us whether the disposer goes on the larger or the smaller bowl, and we mark both waste centres on the drawing before you release the cabinet order.

    Cabinet makers who run the same layout across many units should take the bowl split and waste centre from our drawing and freeze them before production.

    DAILY USE

    How a 60/40 split works in a busy kitchen

    FD3321 suits residential and light-commercial kitchens, where one sink has to cover washing, soaking and rinsing.

    Fill the larger bowl with wash water and use the smaller bowl as the rinse side. Dishes drain without crowding the main basin, and a garbage disposal fitted on the smaller side keeps scraps out of the wash water.

    At 18 gauge (1.2 mm) the wall stays manageable for installers handling a double bowl unit, which is heavier to lift than a single basin of the same width.

    Because the brushed finish is applied across the whole apron and both bowls, the sink looks uniform in a showroom and in a finished kitchen.

    CERTIFICATION

    cUPC certified, with documents for the submittal

    ORDERING

    Fifty pieces, with the bowl split fixed in writing

    SANIKB makes this sink at our own factory in Foshan, so the split, the gauge and the carton can be agreed before cutting steel.

    within 12 business hours

    Distributors can add a brand plate, an own barcode and custom carton artwork through the SANIKB OEM and ODM program. Approve a sample first, because the lead time starts from that approval.

    A showroom can show this double bowl 33 inch farmhouse sink next to the single bowl FS3321 in the same footprint.

    Buyers who want a different bowl ratio, apron radius or gauge should list it in the enquiry. We quote a changed specification as a separate line so the standard model stays comparable.

    FAQs

    How are the two bowls of the FD3321 divided?

    FD3321 uses an asymmetric 60/40 layout. One bowl is larger for pots and baking trays, and the smaller bowl suits rinsing or the disposer. Both are 10 inches deep inside a 33 inch body, and the front is a curved apron with small-radius corners.

    What gauge is this stainless steel country kitchen sink?

    At 18 gauge (1.2 mm), FD3321 uses SUS304 stainless steel with a brushed finish. As a manufacturer we can quote a different gauge, outer size or bowl ratio under OEM and ODM terms, and the minimum order for a changed spec is confirmed in the quotation.

    Which cabinet does a 33 inch farmhouse sink like FD3321 need?

    Plan a 36 inch sink base with an apron cutout; that is the cabinet size this 33 inch farmhouse sink needs. The unit measures 33 x 21 x 10 inches, so the base must carry two filled bowls and a front rail cut away. We send a drawing with bowl widths and waste centres on request.

    What MOQ and lead time apply to FD3321?

    MOQ is 50 pcs and standard lead time is 30-45 days after sample approval. Name the destination country in the enquiry so the quotation lists the right documents. Send the model, the quantity and any change to the bowl split or gauge, and we quote the full order together.

    Can FD3321 carry our own brand and carton?

    Yes. Brand plate, own barcode and carton artwork are standard OEM work at our factory. Send the model, the quantity and the artwork files, and we quote the branded run together with any size change and the documents your market needs.
