FAQs

What are the dimensions of this black offset double bowl quartz composite sink?

This model measures 780 × 500 × 200 mm, equal to approximately 31" × 20" × 8". The size makes it suitable for kitchen sink distributors, showroom displays, builder packages, and project specification review.

What makes the offset double bowl layout useful for B2B buyers?

The offset design provides one larger bowl and one smaller bowl, giving end users more flexibility for washing, rinsing, prep work, and cleanup. For distributors and showrooms, this creates a stronger selling point than a basic equal-bowl sink and helps expand the product range with a more functional design.

Is this sink suitable for private-label programs?

Yes. This sink can be used for private-label kitchen sink programs depending on order requirements. Buyers can discuss logo use, carton design, product labeling, packaging format, and related OEM/ODM support before confirming production details.

Can SANIKB support samples before bulk orders?

Yes. B2B buyers can request samples to check the black quartz composite finish, bowl layout, dimensions, packaging quality, and overall market fit before placing a bulk order or launching a private-label program.

What types of buyers is this sink designed for?

This model is suitable for kitchen sink importers, plumbing distributors, wholesalers, kitchen and bath showrooms, cabinet suppliers, countertop contractors, builders, multifamily project buyers, hospitality project buyers, and private-label brands.

What information can SANIKB provide for quotation or project review?

SANIKB can provide model specifications, product images, packaging details, and other product information needed for distributor review, project quotation, or private-label planning. Buyers can send target market requirements or project specifications to confirm available supply options.
