Product Overview
The Hamat PRI-3318DR is a 33-inch undermount stainless steel kitchen sink with an asymmetrical 70/30 double-bowl layout. Its larger main bowl gives you the working room needed for washing cookware, preparing meals, and handling everyday cleanup, while the smaller prep bowl on the right keeps a separate space available for rinsing produce, draining utensils, or managing a second task. The main bowl measures 21 inches by 16 inches and is 10 inches deep. The right prep bowl measures 9 inches by 16 inches and is 8 inches deep. This divided arrangement is useful for kitchens where separate work zones are preferred without giving both bowls the same amount of space.
The sink is made from 18-gauge stainless steel and is designed for undermount installation, creating a clean transition from the countertop into the bowls. Rear-set drain placement helps preserve usable bowl space, while zero-radius corners and scored bowl bottoms give the sink its squared, contemporary profile. TotalGuard+ insulation helps reduce sound and condensation around the sink body. The PRI-3318DR requires a minimum 36-inch base cabinet. Because this model has a right-side prep bowl, confirm the orientation, cabinet opening, countertop cutout, drain connections, and mounting requirements before installation. Use the current Hamat specification sheet and undermount installation instructions when planning the project.

Why Buy the Hamat PRI-3318DR From Big Frog Supply?
Choose the PRI-3318DR when your kitchen layout works best with the smaller prep bowl on the right and the larger main bowl on the left. This orientation can better match a right-side preparation area, dishwasher placement, or the way you move between food prep and cleanup.
