Quartz Composite Materials, Strength & Durability

SN8549 is produced from quartz composite using a blend of quartz, sand, and composite binders, delivering high strength and stable structure compared with many other materials used in kitchen sinks. The composite matrix is designed to be highly resistant to daily wear, helping reduce risks of scratches, chips, cracks, and stains over long project cycles. The non-porous surface supports a hygienic environment by limiting water absorption and reducing potential bacteria buildup. Performance under heat exposure is controlled to support durable use in high-frequency kitchen applications.

Surface Finish, Colour Options & Maintenance Control

The sink features a smooth matte finish designed for consistent appearance and easy clean routines across multiple units. For daily maintenance, wipe the surface with a damp cloth, then dry to reduce water marks and keep the finish stable over years of use. The surface is engineered to be resistant to discoloration and general tear from repeated handling. SANIKB supports project-aligned colour options, including white, black, and mocha, allowing sourcing teams to match architecture and countertop selections while maintaining material consistency and procurement quality targets.

Undermount Installation, Countertop Fit & Structural Details

SN8549 is designed for undermount installation beneath quartz or granite countertop cutouts. Controlled sink geometry and reinforced mounting edges help reduce install variation, improving repeatable alignment in multi-unit projects. The flat underside supports stable contact surfaces during installation, helping minimize fit issues and stress concentration around countertop edges. This approach is intended to make installation easier for contractors, reduce common installation issues, and protect long-term durability. For project planning, SANIKB can provide drawings to confirm countertop cutout, cabinet space, and plumbing clearance requirements.

B2B Supply, Quality Assurance & Warranty Support

SANIKB supplies SN8549 as a standardized quartz composite kitchen sink platform for distributors, developers, and OEM programs. Production control focuses on stable materials, finish consistency, and repeatability to support long-term supply without frequent specification changes. OEM options can include packaging customization, color selection, and labeling to fit procurement workflows. Quality control checkpoints are applied to support measurable durability and reduce defect risk during shipping and installation. Warranty terms are available for B2B customers based on project scope, order structure, and distribution requirements.

Drop-In Single Bowl

A White Drop-In Bowl Measuring 33 by 22 Inches

SN8549 is a single bowl kitchen sink in quartz composite, finished white and dropped into the worktop from above.

01 / RIM

The rim carries the sink

A drop-in rests on the worktop and is held by its own rim. The cut-out edge stays hidden, which keeps stone and laminate fabrication simple.

02 / WHITE

White is the only published finish

One finish keeps a volume line simple to order. Check the white against your worktop and cabinet samples, because white shifts between suppliers and between photographs.

Drop-in models are compared by outside dimension first. The countertop mounted kitchen sinks group holds the other formats that sit on top of the worktop.

Fit & Clearance

Worktop Cut-Out and Cabinet Width for SN8549

A drop-in is set by the cut-out rather than by the cabinet face.

The size is 33 in wide by 22 in front to back, with 10 in as the third figure. The first two are outside body dimensions and not the cut-out. Cut-out size and rim allowance both come off the drawing.

Twenty-two inches front to back leaves little spare on a shallow top. Check the run from the front edge to the back wall, and check where tap holes sit, before the worktop is templated.

Confirm on the drawing whether the 10 in figure is bowl depth or overall body height before the top is fabricated.

White

Quartz composite in white

Quartz composite is the stated body material and white the stated finish.

Tone is the thing to lock down on a white body. Approve it once from a sample in hand, then book the sinks for one project together rather than topping up from a later run.

Approve colour from a current physical sample rather than from catalogue photography.

Material and Build: Quartz Composite Drop-In

The SN8549 is molded from approximately 80% crushed natural quartz combined with high-grade resin, giving a hard, non-porous quartz composite sink that shrugs off scratches, stains, and thermal shock up to roughly 535F (280C). The White pigment is dispersed through the full blank, so wear never exposes a different undertone. A generous 10" single bowl handles sheet pans and stockpots, and the matte-smooth interior resists water spotting. Compare bowl depths and finishes across the wider quartz sinks range to spec one consistent material throughout a build.

Installation and Daily Use

Designed as a top-mount, the SN8549 lowers into a cut counter opening and seals with a bead of silicone under the rim, no specialty hardware required, which speeds installation on renovation and new-build projects. The 33" x 22" body suits a 36" base cabinet, and the deep 254 mm bowl reduces splash. Clean with mild soap and water; avoid abrasive pads and undiluted bleach on any quartz finish. Templates and rough-in data for the complete quartz sinks line are available for trade and site teams.

OEM and Custom Orders

SANIKB manufactures the SN8549 directly and supports private-label and contract supply. We adjust finish color, bowl size and depth, drain location, and packaging to your brand, with competitive MOQs for wholesalers, hotel groups, and builders. Ask for samples, co-branded spec sheets, and volume pricing to build a complete quartz sink program from a single factory source.

FAQ

What should buyers confirm for the SN8549 white quartz-composite drop-in sink?

The SN8549 is listed as a white quartz-composite drop-in sink with overall dimensions of 33" × 22" × 10" (838 × 559 × 254 mm). Before selecting it for a countertop package, confirm the approved cutout, rim bearing, fixing and support requirements with the fabricator and installer. Specify the countertop material and finish so the installation detail can be agreed for that project. Review the actual cabinet clear opening, faucet drilling or position, and waste and trap clearances on the model drawing. Confirm the supplied fittings in the quotation. For other mounting configurations, compare our quartz sinks page before approving the countertop order.

Will the White finish discolor or yellow over time?

The White SN8549 is pigmented throughout the quartz composite blank and sealed by a non-porous resin matrix, so it does not yellow from UV or absorb dyes from food and drink the way coated or enamel surfaces can. Routine wiping plus an occasional baking-soda paste keeps it bright. Other neutral and dark tones in the same body are listed in our quartz sinks collection for coordinated specs.

What size cabinet does the 33-inch SN8549 need?

The 33" x 22" footprint drops into a standard 36" base cabinet, leaving room for the rim overlap on each side; the 10" (254 mm) single bowl clears typical drain and disposal plumbing. We provide a full-scale cutout template and rough-in drawing on request through our quartz sinks line so installers can pre-cut counters accurately.
