FAQs

What are the dimensions of Model SN3321-MB?

SN3321-MB measures 33 × 21 in (838 × 531 mm) as a single-bowl quartz composite farmhouse sink. These figures cover overall width and front-to-back depth; please verify the full dimensions, including bowl depth, against the confirmed factory spec drawing before production. All sizes can be customized for OEM, ODM, and project orders.

How is Model SN3321-MB installed?

SN3321-MB is a farmhouse sink with an exposed curved apron front. It is designed for apron-front (farmhouse) cabinets and can be set as undermount or top-mount depending on your countertop and cabinet build. Confirm the cabinet cutout, support, and apron reveal against the spec drawing before fabrication.

What is Model SN3321-MB made of?

It is molded from quartz composite (a granite-and-quartz blend) in a matte black finish. Quartz composite is valued for its resistance to scratches, heat, and staining in heavy kitchen use. Matte black is the standard finish shown, and alternative colors can be developed for OEM, ODM, and private-label programs.

Does Model SN3321-MB have workstation features?

Yes. An integrated workstation ledge is molded along the bowl rim so accessories such as a cutting board, colander, or roll-up drying rack can slide across the basin and create a multi-level prep area. Please confirm which accessories are included with your specific order when requesting a quotation.

How does Model SN3321-MB compare with the other apron model?

Both are single-bowl black quartz workstation farmhouse sinks. SN3321-MB has a curved apron front and a 33 × 21 in footprint, while the 33 × 19 in flat-apron model SN3319-MB differs in apron shape and front-to-back depth. Choose by your cabinet depth and the apron look you prefer.

Can SANIKB supply Model SN3321-MB for OEM and wholesale?

Yes. SANIKB is a B2B manufacturer supporting OEM, ODM, private-label, and wholesale buyers, with a minimum order of 50 pcs for this model. Custom colors, sizes, packaging, and branding are available.
