    FAQs

    Is the SN3321-MB a black farmhouse sink with a curved apron?

    Yes. SN3321-MB is a single-bowl black farmhouse sink molded from quartz composite in a Matte Black finish, and its apron front is curved. We build it as a farmhouse workstation sink, so the basin also carries an integrated ledge for sliding accessories. Kitchen distributors and contractors who want a dark apron-front model with prep features can order this one at a minimum of 50 pcs.

    What size is the SN3321-MB 33 inch farmhouse sink?

    SN3321-MB measures 33" × 21" (838 × 531 mm) overall. A spec sheet is available for this model, so ask us for it with your quote request and pass it to your fabricator and cabinet maker before any stone is cut or bases are built. Buyers running OEM or ODM projects can ask us for a custom size; tell us the figures you need when you request a quote and we will confirm them in writing on the quotation.

    What can sit on the workstation ledge of the SN3321-MB?

    SN3321-MB has an integrated ledge that lets a cutting board, colander or drying rack slide across the basin. Prep work can then happen above the single bowl: chop on the board, rinse produce in the colander, and let washed dishes drip into the sink from the rack. Please list the accessories you want packed with each unit in your inquiry, and we will confirm them on the quotation.

    How does the SN3321-MB compare with the SN3319-MB?

    SN3321-MB has a curved apron front and measures 33" × 21"; SN3319-MB has a flat apron front and measures 33" × 19". Both are single-bowl black quartz workstation farmhouse sinks. Pick the curved apron when you want a rounded front profile, or the flat apron for a straight face, and choose the front-to-back depth that suits your cabinet line.

    Can SANIKB make the SN3321-MB in other colors for private label?

    Yes. Matte Black is the standard SN3321-MB finish, and SANIKB develops custom colors for OEM, ODM, private-label and wholesale buyers. Send the target shade, quantity and destination market, and we will quote lead time per model along with project pricing. Compliance documents are matched to the destination market at quotation.
