FAQs

Who is this black quartz composite sink suitable for?

This model is suitable for distributors, importers, wholesalers, kitchen cabinet dealers, builders, contractors, multifamily project buyers, hospitality buyers, and private-label sink brands that need a modern black single bowl kitchen sink for bulk or project supply.

What are the dimensions of this sink?

The sink measures 780 × 480 × 220 mm, equal to approximately 31" × 19" × 9". This size gives buyers a clear specification for cabinet planning, countertop coordination, catalog listing, and project quotation.

Why choose a single bowl layout for kitchen supply programs?

A single bowl layout provides more uninterrupted basin space than divided sinks, making it practical for washing larger pans, trays, and cookware. For builders, remodelers, and project buyers, it is also a straightforward sink format that fits many modern kitchen layouts.

Can this sink be supplied for private-label programs?

Yes. SANIKB can support private-label requirements such as logo options, carton design, product labeling, export packaging, and model documentation based on the buyer’s program needs. Final details can be confirmed during sample review and quotation.

Can buyers request samples before placing a bulk order?

Samples can be requested so buyers can check the black quartz composite finish, sink dimensions, material feel, packaging method, and overall workmanship before confirming a larger order.

What information can SANIKB provide for procurement review?

SANIKB can provide model-level specifications, product photos, packaging information, installation-related details, and quotation support. Buyers can send project requirements or purchasing plans to confirm whether this sink fits their wholesale, private-label, or project supply program.
