With an outer dimension of 32" L x 19" W x 10" D and a bowl depth of 9 3/8", it offers ample space for various kitchen tasks. Made from 80% natural quartz and high-performance acrylic resin, it provides the appearance and feel of real stone while ensuring long-term resilience. The metallic black finish adds a modern touch to any kitchen decor and pairs seamlessly with an undermount installation, making it easy to clean and maintain since spills can be wiped directly into the sink without any exposed rims trapping debris.

The kit includes practical accessories like a heavy-duty cutting board, roll-up dish drying rack, and a powerful 3/4 HP garbage disposal with continuous feed functionality, which simplifies waste management. The garbage disposal features a powerful 3800 RPM motor and a motor-saving shut-off system to prevent damage from blockages. The Universal Design ensures compatibility with standard kitchen plumbing connections, and the EZLock mounting assembly makes installation straightforward. One potential drawback is its weight at 44.6 pounds, which might require additional support during installation.

Customer reviews are generally positive, rating it 4.4 out of 5 stars, indicating satisfaction with its performance and aesthetic appeal. Maintenance is straightforward, requiring only a dry cloth for wiping. This sink is ideal for users looking for a durable, stylish, and functional addition to their kitchen setup.

The KRAUS Quarza 33-inch undermount granite composite kitchen sink is a solid choice if you want a durable and stylish sink that fits well in modern or traditional kitchens. Made from quartz composite, it resists scratches, impacts, and stains better than many other materials, making it ideal for busy kitchens. Its black onyx finish with shimmering metallic particles adds a touch of elegance without being overly flashy.

The sink size is quite practical with two equally sized bowls (50/50 split), each about 9.5 inches deep, which helps contain splashes and manage large pots and pans. The undermount design not only looks sleek but also makes cleaning countertops easier since you can wipe debris straight into the sink without any lip to catch dirt. Installation requires a minimum 36-inch cabinet, so you’ll need to make sure your kitchen can accommodate that size.

Cleaning is straightforward due to the sink’s smooth, non-porous surface and gently rounded corners that prevent buildup. The sink’s weight (around 38.5 pounds) means you’ll want a strong cabinet structure and professional installation might be a good idea. While the dark black finish looks great, it may show water spots or soap residue more than lighter colors, so some regular wiping might be necessary to keep it looking its best. Backed by a limited lifetime warranty and positive customer reviews, this sink balances durability, style, and ease of maintenance for most home kitchens.

Measuring 32 inches in length, 19 inches in width, and 10 inches in depth, it offers ample space for washing large items with less splatter, aided by its single bowl design.

These additions make it a multi-functional workspace that can streamline kitchen tasks.

Cleaning is made easier thanks to the non-porous, dense granite composite material and rounded EZClean corners that prevent buildup.
