Stainless Steel Bar and Prep Sink for Compact Undermount Installations

The Karran Edge 300 E-312 is an 18-gauge stainless steel single-bowl bar and prep sink that installs seamlessly beneath laminate or solid surface countertops, bringing durable utility to tight spaces where a full kitchen sink is more than the layout calls for.

Key Features

• 18-gauge stainless steel construction delivers solid bowl thickness for a compact bar and prep sink.
• Seamless undermount installation designed specifically for laminate and solid surface countertops.
• 15-1/4 inch square footprint fits in a minimum 18-inch-wide cabinet, ideal for islands, bars, and secondary prep stations.
• Single equal bowl with a 13 by 13 inch interior and 5-3/4 inch depth for practical washing and rinsing capacity.
• 3-1/2 inch drain opening accepts standard drain fittings.
• IAPMO certified to meet plumbing product standards.

Where This Sink Earns Its Place

A full-size kitchen sink can overwhelm a wet bar, a kitchen island, or a secondary prep station. The E-312 fits exactly where those spaces call for a dedicated washing bowl without surrendering valuable counter run. At 15-1/4 inches square, it tucks into a cabinet opening as narrow as 18 inches, so it works in tight island layouts, butler's pantries, and outdoor kitchens with a covered countertop surface. The single bowl keeps the design clean: one compartment for rinsing produce, filling pitchers, or prepping ingredients while the main sink handles cleanup elsewhere.

Stainless Steel Build and Finish

The sink body is 18-gauge stainless steel, thick enough to resist flex and denting under daily bar and prep use. The stainless finish reads as a neutral that coordinates with most kitchen hardware, from brushed nickel faucets to commercial-style fixtures. Because this is a seamless undermount, the bowl bonds directly into the underside of the countertop with no exposed rim above the surface, keeping water and debris from collecting at the edge and making the counter easy to wipe clean straight into the bowl.

Planning the Install

This sink is built to seamlessly undermount into laminate and solid surface countertops. That countertop compatibility is a distinguishing detail: most stainless undermount sinks are specified for stone, but the Edge 300 is engineered for laminate and solid surface, which opens it up to a broader range of countertop materials and budgets. Confirm the cabinet is at least 18 inches wide and that the countertop fabricator knows the sink profile before the cutout is made. The drain opening takes a standard 3-1/2 inch fitting, and a faucet is sold separately.
