The Allora 30/70 Offset Double Bowl Stainless Steel Sink flips the traditional layout by placing the compact bowl on the left and the spacious primary bowl on the right. This configuration is ideal for kitchen designs where the prep zone or faucet setup is better aligned with a right-side workspace. The large 70% bowl offers plenty of room for soaking and scrubbing large cookware, while the smaller 30% bowl is perfect for rinsing produce, drying utensils, or handling everyday tasks.
