    DRAINBOARD BODY

    33 inch black drop in kitchen sink with drainboard

    Beside a 33 inch black double bowl, SN8549B drops the second basin for a drainboard-style work area and grows to 22 inches front to back.

    You get one large single bowl plus a flat zone for resting washed items, in matte black quartz composite.

    Dealers use it where buyers ask for a single basin without giving up surface for drying and sorting.

    Overall width and bowl length differ, so plan the cutout from the overall size.

    CHOOSING

    Drainboard single bowl or a double bowl

    The same 33 inch width can be built several ways. These are the trade-offs buyers weigh.

    Against a double bowl

    You lose the divider and the second basin. You gain a large open bowl and a separate flat surface.

    Against a plain single bowl

    A plain body spends its whole footprint on the basin. Here the drainboard area takes part of it.

    Deeper body

    At 10 inches, this is the deepest body in our black quartz drop-in group, which helps with large cookware.

    FAQs

    What are the main dimensions of this 33 inch black drop in kitchen sink with drainboard?

    Overall size is 838 × 559 × 254 mm, or 33" × 22" × 10". The bowl itself is 788 mm long, 412 mm front to back, and the sink is 254 mm deep. Use the overall size for the countertop cutout and the bowl values for capacity. Ask for the drawing if your dealer file needs a dimensioned sheet.

    Does SN8549B include a faucet hole?

    Yes. The deck has a Ø35 mm faucet hole, the usual size for a kitchen faucet. Check the faucet's shank diameter before a bulk order, and ask us if the project needs a different hole layout or an accessory hole. Sample units help with that check.

    Why add a drainboard to a drop in kitchen sink?

    A drainboard-style zone gives washed items a resting place beside the bowl. That helps apartment kitchens and hospitality units where counter space is short. It is a layout choice, so show buyers both the bowl and the flat area in a showroom set.

    Can SN8549B be supplied for private label or OEM projects?

    Yes. SANIKB can discuss branding, packaging, documentation and specification support for distributors and sink brands. Send your target market and order plan, and we will confirm what is workable. Our OEM and ODM service page explains the process, and a sample of the drainboard body can be sent first.

    How do we request a quotation for SN8549B?

    Send the quantity, destination market, packaging requirements and any project specification. SANIKB can then prepare a bulk quotation, with sample support if you want to inspect the matte black finish and drainboard area first. Mixed container loading is accepted, so SN8549B can ship with other models.
