Black Quartz Sink – Double Bowl Quartz Kitchen Sink
Drop-In Double Bowl
A matte black deck sitting on top of the worktop
The mount named for SN8456 is drop-in. That one line decides the sequence on site, because the worktop is cut before the sink ever arrives.
Rim carried by the counter
On a topmount the cut edge of the worktop finishes under the rim. Cutout dimensions still come off the factory drawing, so request it before the top is ordered.
838 × 559 mm, two bowls
Plan size is 838 × 559 mm at a depth of 254 mm. The 559 mm front-to-back figure is the one to test against the counter first.
Stocked alongside undermount bodies, this is the topmount entry in the countertop kitchen sink range.
Fit & Clearance
Counter depth decides whether this model drops in
The 559 mm dimension is the constraint most projects meet first.
Measure from the front edge of the worktop to the wall or backsplash before specifying. A shallow run leaves very little behind the sink once the rim is accounted for.
Deck holes need settling early, because the deck stays in view. No hole configuration is published on this page, so confirm it on the drawing.
Ask for the cutout template with the drawing so the fabricator works from factory data.
Construction & Finish
The deck stays visible, so the black gets signed
Rim and deck remain in sight once this model is fitted. Colour approval moves ahead of most other questions on the order.
Quartz composite, Matte Black
Material and finish are what the specification states for SN8456. Anything further about the surface should be asked for rather than assumed.
Decide who signs the black sample and keep that reference in the order file. Ask separately for any surface or weight figure a submittal calls for.
Photographs are not a colour approval. Work from an agreed physical sample.
Compliance
Documentation is agreed per market for SN8456
A topmount fabricator needs cutout data before the worktop is ordered. Ask for that ahead of the rest of the pack.
Nothing in the SN8456 record amounts to a certification or a listing. Read this page as commercial information only.
Selling into a regulated market changes what you need on file. Name that market in the enquiry and we will say what is available before a proforma is issued.
Procurement
Wholesale terms for the SN8456 drop-in
Two open decisions hold up a topmount order more often than commercial terms do.
They are the deck hole layout and the finish sign-off. Settle both inside the enquiry, because changing either after the proforma moves the schedule.
Drilling the deck to your own pattern makes this an OEM item. See how SANIKB runs OEM and ODM work before the pattern is fixed.
Include these details with the RFQ
- Order volume, and any split across finishes
- Regulated market the goods are entering
- Tap hole count and position wanted on the deck
- Worktop material and thickness at the cutout
- Who signs the Matte Black approval sample
- Waste and overflow arrangement, if supplied
- Carton, pallet and container loading plan
- Label, barcode and manual language
Ask what the quoted lead time is counted from when the quotation is issued.
How we work
From enquiry to shipment
A factory-direct process built for importers, distributors and project buyers. No trading layer in between.

Our sales team contacts you
A named account manager follows up by email or WhatsApp, confirms the specification and clarifies anything missing before pricing.

-
04
Sample approval
We send a sample for finish, function and packaging sign-off. Branded samples are produced once artwork is confirmed.
-
05
Production and shipment
Mass production starts after sample approval and deposit. QC and inspection run before loading, then the order ships to the agreed port.
OEM and ODM to your specification
We develop to a brief. Send a reference model, a drawing or simply the price band and market you are targeting, and we will propose what fits. Entry, mid and premium builds are all available from the same factory.
- Your logo on product, carton and documentation
- Private-label packaging and manuals

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.
