An ADA-Compliant Undermount Sink for Vanity Installations

The Karran Edge 300 E-305 is a single-bowl stainless steel undermount vanity sink designed for ADA-compliant bathroom installations, mounting seamlessly beneath laminate and solid surface countertops.

Key Features

• ADA compliant and cUPC certified for installations that meet accessibility requirements.
• Seamless undermount installation into laminate and solid surface countertops.
• 18-gauge stainless steel construction with a stainless steel finish.
• Single bowl configuration with a 12-3/4 inch square interior and 5-3/4 inch depth.
• Minimum 18-inch cabinet width required for proper fit and installation.
• 1-3/4 inch drain opening sized for a standard vanity drain fitting.

Built for ADA Vanity Applications

This sink is the choice when a vanity installation needs to meet ADA compliance, whether in a residential accessible bath, a commercial restroom, or a healthcare or hospitality setting where accessibility is required or preferred. The shallow 5-3/4 inch bowl depth keeps the basin within ADA reach and knee-clearance guidelines, and the compact 15-1/4 inch square footprint fits comfortably over an 18-inch-wide cabinet. The cUPC certification confirms it meets North American plumbing product standards.

Stainless Steel in a Seamless Undermount Format

The sink is 18-gauge stainless steel, a solid mid-range gauge for a vanity application where the bowl handles everyday hand-washing use rather than heavy kitchen loads. What sets this sink apart from a standard undermount is how it installs: the seamless undermount method bonds the sink directly beneath laminate or solid surface countertops, eliminating the exposed rim gap that a standard undermount can leave at the countertop edge. The result is a continuous surface that is easier to wipe clean and reads as part of the counter rather than a separate insert.

Where This Sink Fits

This sink is sized for bathroom vanities, powder rooms, and accessible restrooms rather than kitchens. The 15-1/4 by 15-1/4 inch overall dimension suits a single-basin vanity or a smaller countertop run. Because it installs by seamless undermounting, it is the right call when the countertop is laminate or solid surface and the design calls for a smooth, integrated look. If the countertop is quartz, granite, or another hard stone, a different sink in the Karran line is the better fit for that material.
