Stainless Steel Double-Bowl Sink for Seamless Undermount Installs

The Karran Edge 300 is an 18-gauge stainless steel kitchen sink with equal 50/50 double bowls that installs seamlessly beneath laminate or solid surface countertops. It is engineered specifically for seamless undermounting, a mounting method rarely supported by standard stainless sinks, making it a practical choice for kitchen remodels built around those countertop materials.

Key Features

• Seamless undermount installation designed for laminate and solid surface countertops, eliminating the exposed rim at the counter edge.
• Equal 50/50 double bowl configuration splits the sink into two identical basins for separating wash and rinse tasks.
• 18-gauge stainless steel construction across the Edge 300 series.
• 32-1/2 inch overall length requires a minimum 36-inch cabinet width.
• 8-1/2 inch bowl depth provides generous capacity for pots and tall items.
• IAPMO certified for plumbing code compliance.

Two Bowls, One Unbroken Counter Surface

Most undermount sinks are designed for stone countertops. The Edge 300 is different: its seamless undermount design bonds directly into laminate and solid surface countertops, creating a smooth, continuous transition from counter to basin with no exposed rim or gap where water and debris can collect. That detail matters most in a working kitchen, where the counter takes daily abuse and cleanup needs to be straightforward. The equal bowl split means both sides share the same usable dimensions, so the choice of which side to use for soaking and which to keep clear for rinsing or food prep stays flexible.

18-Gauge Stainless Steel Construction

The sink body is stainless steel at 18 gauge, a practical middle-ground thickness that holds its shape under the stress of daily use without the added cost of heavier-gauge material. The stainless finish is consistent across the bowl interior and exterior, and the double-bowl configuration is formed as a single unit rather than two separate basins joined together. Each bowl measures 16-1/2 inches wide by 14 inches long, with an 8-1/2 inch depth that handles full-size stockpots and baking sheets comfortably. The drain opening is 3-1/2 inches on each bowl, a standard size for compatible strainers and disposal flanges.

Where This Sink Fits

This sink is built for kitchen installations where the countertop is laminate or solid surface and an undermount look is the goal. That combination is common in production homes, rental properties, and budget-conscious remodels where laminate countertops offer a cost-effective surface without sacrificing the clean sightlines of an undermount bowl. Cabinet shops and contractors speccing a complete kitchen package will find the 36-inch minimum cabinet requirement straightforward to plan around. Designers working with solid surface countertops benefit from the seamless bond, which can be finished flush for a monolithic counter appearance. This is not the sink for tile, quartz, or granite countertops; those materials call for a different mounting approach.
