10 Best Granite Composite Sinks 2025 in the United States

The KRAUS Quarza 31-inch Drop-In/Undermount Single Bowl Granite Kitchen Sink is a solid choice for those looking for both style and durability in a kitchen sink. Made from a blend of natural quartz and acrylic resin, it offers a beautiful black onyx finish that mimics natural granite while being resistant to scratches and impacts. This makes it ideal for busy kitchens where durability is key. Its size and depth provide ample space for washing dishes and minimizing splashes, which many users will appreciate.

Installation is quite flexible, as it can be mounted as either a drop-in or undermount sink, fitting well with various countertop styles. The thick mounting deck gives it a polished appearance, and the included stainless steel drain assembly is a handy addition. Cleaning is easy, thanks to the smooth, non-porous surface that resists stains and helps keep maintenance to a minimum.

However, it does have a few drawbacks. Being a single bowl sink, it may not meet the needs of larger families or those who prefer multitasking in their kitchen. While its weight (around 31.9 pounds) is manageable, it might require some extra support during installation. Additionally, the black finish, while stylish, may show water spots and fingerprints more readily than lighter colors, requiring regular wiping to maintain its appearance.

The Black Onyx finish adds a modern touch and the metallic particles in the composite give it a subtle shimmering effect.

Maintenance is straightforward due to its non-porous surface, which resists stains and can be cleaned with standard household cleaners. Rounded corners also help minimize dirt buildup. However, it requires a minimum cabinet size of 33 inches, which might limit its compatibility with smaller kitchen layouts.
