Granite Composite Double Bowl Kitchen Sink, 860mm x 500mm, Black

Granite Double Bowl Sink

The Granite Double Bowl Sink provides a high-density, non-porous surface designed to withstand the rigorous demands of commercial and residential food preparation areas. This fixture utilizes a composite of 80% natural quartz and 20% high-grade acrylic resin to ensure structural integrity under thermal stress. It fits standard kitchen cabinetry and offers a top-mount installation profile for secure seating on various countertop materials.

Built for the Job

Site supervisors and plumbers select this composite fixture because it eliminates the resonance and ‘clatter’ associated with thin-gauge stainless steel. The thick-walled construction naturally dampens sound from water flow and heavy cookware. The material density provides exceptional resistance to mechanical impacts, reducing the risk of chipping or cracking when heavy pots contact the basin floor. Contractors find the top-mount design efficient for rapid installation during final fit-out stages, as the broad rim covers minor cutout inconsistencies in laminate or stone surfaces.

• Heavy-use residential kitchens requiring a scratch-resistant basin for daily maintenance.

• Multi-unit housing projects where durable, low-maintenance fixtures reduce long-term costs.

• Commercial breakrooms requiring heat-resistant surfaces for hot liquids and cookware.

Product Highlights

Thermal Shock Resistance

The basin withstands temperatures up to 280°C without warping, discoloring, or losing structural bond strength.

Non-Porous Surface

• Resists absorption of food dyes, acids, and chemical cleaners.
• Prevents bacterial colonization within the material structure for improved hygiene.

On-Site & Workshop Notes

• Always use the physical unit as a template for the final cutout to ensure precise fitment on the benchtop.

• Clean the underside rim with denatured alcohol before applying the recommended sealant for a watertight bond.
