Black Quartz Sink with Natural Quartz Composite
This black quartz sink is manufactured from natural quartz composite, delivering stable structure, rich colors, and long-term durability. Compared with traditional kitchen sinks, the quartz composite surface resists stains, scratches, and daily wear while maintaining a consistent black finish suitable for modern kitchen décor.
Double Bowl Kitchen Sink Configuration
Designed as a double bowl kitchen sink, this model provides balanced working zones for washing, rinsing, and food preparation. The double equal bowl layout improves efficiency in residential kitchens, mudrooms, and utility rooms, while still supporting single bowl usage when required
Undermount Quartz Kitchen Sink Installation
This quartz kitchen sink is engineered for undermount installation, allowing clean integration with quartz, granite, and stone countertops. The undermount design improves countertop access, simplifies cleaning, and creates a clean, uninterrupted kitchen surface.
OEM & ODM Quartz Sink for Project Supply
Supplied for OEM and ODM quartz sink programs, this model supports multiple colors including black, white, gray, and brown. Controlled production, stable material quality, and batch consistency make it suitable for long-term kitchen sink supply and project-based distribution.
TWO BOWLS, TOPMOUNT
Quartz drop in sink: two bowls, matte black, 838 mm
Three choices define SN8456: two bowls, a top mount rim and a Matte Black finish. Together they make a black quartz double bowl drop-in kitchen sink 33 inch wide, a quartz composite sink that fits a standard run of base cabinets and any kitchen design built around a quartz drop in sink.
Two bowls, one divider
One side can soak while the other drains. Drain positions follow the supplied template, so check them against the plumbing layout before cabinets are built.
Top mount rim
The sink drops into the counter cutout and seals under the rim with silicone. No underside clips are needed, which simplifies both renovations and new builds.
Black through the body
Matte Black pigment runs through the full composite blank, so the divider and bowl walls keep an even tone rather than showing a pale core.
Compare a single bowl or other bowl counts in the quartz sinks range.
CUTOUT & CABINET
Fitting 838 × 559 mm into a 36 inch cabinet
Depth from front to back, 559 mm, is the dimension projects meet first. Measure to the wall or backsplash before the worktop is ordered.

A 33 inch by 22 inch footprint suits a 36 inch base cabinet, which keeps the kitchen sink size in step with standard cabinetry. Confirm the clear opening inside the cabinet and the rim bearing on the worktop before drawing the cutout.
Faucet drilling and the waste and trap clearance belong on the same drawing. Ask for the cutout template with the model drawing, so the fabricator cuts from factory data.
Settle tap hole count and position early, because the deck stays in view.
QUARTZ COMPOSITE
What the matte black composite means on site
SN8456 is a quartz composite kitchen sink molded from approximately 80% natural quartz aggregate in a resin binder.
Matte Black
Non-porous, colour through
A non-porous body keeps coffee and wine from staining, and scuffs or minor chips do not expose a pale core.
A matte surface hides water spots and fingerprints better than glossy black. Routine wiping keeps the tone uniform, and abrasive pads should stay away from it.
Black is the colour a client will remember, so agree a physical sample before production and file it with the order.
This quartz composite sink also withstands temperatures to roughly 535F (280C), so a hot pan set down at the edge is not a worry on a busy line. Colour stays even through the quartz composite body.
PROJECT FIT
Kitchens that suit a 33 inch double bowl
Name the destination market in your request so the certificate documents match the order.
Residential developers use a double bowl drop-in where the countertop is already cut to a standard base. It saves redesigning the cabinet run.
For kitchen design in hotel suites with kitchenettes and rental apartments, the double bowl gives two usable bowls from a single sink footprint, without moving to a larger cabinet.
Retail and showroom buyers can pair it with other drop-in models from our quartz sinks line, so bowl counts and finishes stay coordinated across one specification.

The SN8456 is molded from approximately 80% natural quartz aggregate in a resin binder, creating a non-porous quartz composite sink that resists scratching, staining, and heat to roughly 535F (280C). Matte Black pigment is dispersed through the full blank, so the divider and bowl walls stay an even tone despite heavy use. The thick composite also dampens disposal noise and water drumming. Explore the full quartz sinks range to align bowl counts and finishes across a single specification.
The SN8456 is a top-mount sink: drop it into the counter cutout and seal under the rim with silicone, no underside clips required, which keeps installation simple on both renovations and new builds. The 33" x 22" body fits a 36" base cabinet, and the dual 254 mm bowls let one side soak while the other drains. Clean with mild soap and water and skip abrasive pads on the matte black surface. Templates and rough-in data for the wider quartz sinks line are supplied for trade and site coordination.
SANIKB produces the SN8456 in-house and supports private-label and project programs. We adjust finish color, bowl split, drain placement, and retail packaging to your brand, with competitive MOQs for distributors, hotel groups, and builders. Request material samples, co-branded spec sheets, and tiered pricing to standardize a double-bowl quartz sink offering from one factory.
