Understanding Granite Composite Durability

Granite composite is engineered by combining crushed natural granite stone with advanced resins, creating a dense, rock-solid material that behaves much like natural stone without the high-maintenance upkeep. Think of it like a reinforced highway bridge where aggregate stone is locked tightly within a resilient polymer binder, allowing the sink to absorb impact energy and resist scratching, chipping, and thermal shock from sudden temperature changes.

Installation Guide

  • Review the recommended countertop cut out hole of 30 1/4" x 19 1/4" and verify measurements against the included template before cutting.
  • Utilize the included undermount installation hardware to secure the sink safely beneath your solid surface countertop.
  • Pair the rear center 3 1/2 inch drain opening with a compatible strainer model such as the recommended ABST35.
  • Wipe down the smooth surfaces regularly with mild soap and water to maintain the flawless finish.

Care & Maintenance

  • Daily Cleaning Wipe the sink basin with warm water, mild dish soap, and a soft cloth or sponge after each use.
  • Stain Prevention Rinse away coffee, tea, and colored liquids promptly to prevent minor surface residue buildup.
  • Hard Water Care Remove mineral deposits periodically using a mixture of equal parts vinegar and water followed by thorough rinsing.
  • No Sealing Required Avoid applying chemical sealants or waxes, as the nonporous granite composite material does not require sealing.
  • Scouring Avoidance Skip harsh abrasive pads, steel wool, or abrasive chemical cleaners to protect the smooth finish.
