The Allora GC-3118-10-D Granite Composite Kitchen Sink, in a striking black finish, combines the natural beauty of stone with the durability of modern engineering. The sink offers both durability and elegance with its slightly rounded tight-radius corners, delivering a modern aesthetic that enhances any kitchen's appearance. Crafted from a blend of natural granite and acrylic resins, this sink is highly resistant to stains, scratches, and heat, making it as practical as it is stylish. The equal-sized double bowls provide the versatility for independent soaking, washing, or drying while effectively containing mess and splatter. With a well-engineered bottom slope for faster drainage, this sink perfectly balances form and function.
