Bright White Finish and ADA-Compliant Fit in One Undermount Vanity Sink

The Karran Acrylic Series A-306-WHITE is a single-bowl undermount vanity sink in a clean white finish, built to mount beneath laminate or solid surface countertops and sized to meet ADA accessibility requirements.

Key Features

• White acrylic resin construction delivers a smooth, consistent surface that complements a wide range of bathroom palettes.
• ADA compliant design meets accessibility standards for vanity sink installations.
• Undermount installation into laminate and solid surface countertops for a seamless, rimless counter surface.
• Single bowl configuration with a 6-inch inside bowl depth and a 1-3/4 inch drain opening.
• Requires a minimum 21-inch cabinet width, fitting the most common vanity cabinet sizes.

Where White Works Hardest

White is the default vanity color for a reason: it reads clean against every finish from soft gray to warm wood, it shows up well under task lighting, and it does not compete with tile, mirror frames, or fixtures. This sink suits a bathroom where a neutral, finished-looking basin is the goal rather than a statement piece. It works equally well in a primary bath being refreshed, a hall bath serving multiple users, or a new powder room where the designer wants a crisp baseline before adding bolder elements around it.

Acrylic Material and Undermount Construction

The sink body is acrylic resin, a lightweight material that holds color evenly and resists the kind of surface variation that can make ceramic or composite sinks look uneven over time. The white finish runs throughout the material rather than sitting as a surface coat. Undermounting keeps the counter edge uninterrupted so water and debris wipe straight into the bowl, and it removes the rim line that collects buildup on drop-in sinks. This sink is designed for laminate and solid surface countertops specifically, which allows it to bond flush for a tight, gap-free transition at the counter edge.

Who Should Specify This Sink

Cabinet shops and contractors building out standard vanity runs will find this sink fits a 21-inch minimum cabinet width, the common starting point for single-sink bath vanities. The ADA-compliant designation makes it appropriate for projects with accessibility requirements, including universal-design residential builds, assisted living facilities, and commercial restroom renovations. Homeowners specifying a replacement sink for an existing laminate vanity top will find the undermount profile and white finish a straightforward match for most stock countertop options. At 15-1/2 inches front to back, it fits shallower vanities without forcing a countertop change.
