Sink QUADRON CLARK 842 GraniteQ Hard Rock onyx — single-bowl granite composite sink, model CLARK 842

The QUADRON CLARK 842 GraniteQ Hard Rock onyx is a single-bowl granite composite sink designed for everyday kitchen use. Constructed from GraniteQ material with an onyx finish, this sink combines a stone-like appearance with the practical characteristics expected from composite sinks: durability, resistance to surface scratches and common heat exposure, and a uniform matt look that integrates with a variety of countertop styles. The single-bowl layout offers a generous working area for washing large pots, pans and baking trays while fitting standard countertop cutouts.

Advantages

The GraniteQ Hard Rock onyx surface provides increased resistance to abrasion and moderate heat, reducing visible wear in daily use. The composite construction improves impact resistance compared with thin metal sinks and helps maintain temperature stability for dishwashing tasks. The onyx finish delivers an even, non-reflective surface that hides water marks and minor blemishes, simplifying maintenance and preserving a consistent appearance over time.

Suitable for

• Standard household kitchens requiring a durable single-bowl sink
• Homes with frequent cooking and large cookware handling
• Countertops with a standard single-bowl cutout or new installations
• Interiors where a matt onyx stone-like look is desired

Key specifications

• Configuration: single-bowl design providing a large uninterrupted sink area
• Material: granite composite (GraniteQ) with hard rock onyx finish
• Surface characteristics: scratch-resistant and matt stone-like texture
• Thermal resistance: suitable for typical kitchen temperatures and hot water exposure

How to use

Install the sink into a compatible countertop cutout following the countertop and sink manufacturer’s instructions. Use the single bowl as a primary washing area for dishes, food preparation and cleaning large cookware. Rinse and drain as normal; avoid exposing the sink to direct flames or continuous contact with extremely hot objects. For regular cleaning, use non-abrasive household cleaners and soft cloths or sponges to preserve the onyx finish.

Usage recommendations

To maintain appearance and performance, wipe the sink dry after heavy use, avoid abrasive steel wool and harsh chemical strippers, and use a sink grid or mat if dropping heavy cookware into the bowl is likely. Clean with mild detergents and a soft brush for stubborn residues.
