Black 31-Inch Quartz Composite Sink for Distributor and Project Kitchen Programs

This black rectangular single bowl quartz composite sink is designed for B2B kitchen supply programs that need a modern color, practical capacity, and repeatable model specifications. With a 780 × 480 × 220 mm / 31" × 19" × 9" size, it gives distributors, importers, cabinet dealers, builders, and project buyers a clean black sink option for wholesale kitchen lines, multifamily units, remodel programs, and hospitality projects.

Deep Single Bowl Layout for Practical Kitchen Use

The 9-inch deep single bowl provides open washing space for cookware, trays, and daily kitchen cleanup without a center divider. Its rectangular shape works well with contemporary countertop and cabinet layouts, while the faucet hole design supports straightforward project planning for buyers who need a clear sink specification before quoting, sampling, or bulk purchasing.

Factory-Direct Supply with OEM/ODM and Private Label Support

SANIKB supports factory-direct quartz composite sink supply for B2B buyers, including OEM/ODM requirements, private-label packaging, export cartons, product images, model specifications, and sample review. Buyers can confirm color, finish, dimensions, packaging details, and project requirements before requesting bulk pricing or adding this black single bowl sink to a distributor, builder, or private-label product program.

THREE NUMBERS

31 inch black single bowl drop in sink

780 mm wide, 480 mm front to back, 220 mm deep: those are the three values that decide whether SN7848 fits your kitchen.

Model: SN7848
Size: 31" × 19" × 9" (780 × 480 × 220 mm)
Material: Quartz composite
Finish: Matte Black
Mounting: Drop-in
Bowl: Single, rectangular, no divider
MOQ: 50 pcs

Width band: 30–32 in.

OPEN BASIN

A rectangular bowl with no center divider

Without a divider, trays, roasting pans and large pots lie flat in the bowl. The 9 inch depth gives them room to sit below the rim.

The rectangular outline follows cabinet and countertop lines, so it reads cleanly in contemporary kitchens. The matte black quartz composite finish is one color under one model code.

A faucet hole on the deck takes the tap. Confirm the hole count and the faucet model before bulk drilling.

FAQs

What are the dimensions of the 31 inch black single bowl drop in sink SN7848?

Expect 780 × 480 × 220 mm, approximately 31" × 19" × 9". Width runs along the counter, 480 mm is front to back and 220 mm is bowl depth. These three values set the countertop cutout and the base cabinet check, so send them to your installer.

Why choose a single bowl over a double bowl for kitchen supply?

A single bowl gives uninterrupted basin space, so larger pans and trays fit without a divider in the way. Builders and remodelers also find it a simple format to specify across many kitchens, with one cutout and one bowl to plan around. Choose a double bowl only when users need two separate stations.

Who is SN7848 suitable for?

Distributors, importers, wholesalers, cabinet dealers, builders, contractors, multifamily and hospitality buyers, and private label sink brands. It suits programs that want a modern black single bowl kitchen sink for bulk or project supply, whether the order is one apartment block or a showroom range.

Can buyers request samples of SN7848 first?

Yes. Samples let you check the black quartz composite finish, dimensions, material feel, packaging method and workmanship before confirming a larger order. Send your address and target quantity, and SANIKB will arrange the sample with the quotation. Your team can then test the cutout against the real body.

Can SANIKB supply SN7848 under private label?

Yes. SANIKB can support logo options, carton design, product labeling and export packaging based on your program. Final details are confirmed during sample review and quotation, before any production starts. The OEM and ODM service page covers how to start, and samples can be reviewed first.
