The Karran Quattro QM164WH is a single-bowl acrylic vanity sink in a matte white finish, designed for above-counter installation into any countertop material and certified ADA compliant.
Matte white is a finish that steps back rather than competes. On a vessel or above-counter vanity sink, a matte surface reads as intentional rather than simply clean, and it pairs naturally with both warm and cool cabinetry tones without pulling the eye. It is a practical choice for a bath being built around white trim and cabinetry, and an equally good one for a space where the vanity top itself is doing the visual work and the sink should read as part of the surface rather than a focal point.
The sink body is acrylic resin, a material that is lighter than stone composite and shapes consistently in production, which is why the inner bowl dimensions hold tight to the 20-5/8 by 17 inch footprint and the 7-inch depth. The matte white surface is consistent throughout the material rather than a coating applied over a contrasting body, so minor surface marks do not expose a different color underneath. Acrylic is suited to bathroom vanity environments and holds up well to daily use with standard cleaning products.
This sink is a strong fit for an accessible bath or a project where ADA compliance is part of the specification. IAPMO certification means it has been independently tested against recognized plumbing product standards, which matters for permitted residential and light commercial work. Because it installs above the counter and accepts all countertop materials, it works whether the vanity top is prefabricated stone, a custom solid surface build, or a laminate vanity in a secondary bath. Designers specifying a consistent matte white palette across a remodel will find it coordinates well with white cabinetry, white tile, and white or off-white trim without introducing a gloss contrast.
No. It installs above the counter and is compatible with all countertop materials, including quartz, granite, solid surface, laminate, and tile, so it adapts to whatever vanity top is in the project.
ADA compliance indicates the sink meets the dimensional and clearance requirements of the Americans with Disabilities Act for accessible installations. It is relevant for accessible bath projects and often required in commercial or hospitality settings.
The drain opening is 1-3/4 inches, sized for standard vanity drain assemblies. The drain is not included with the sink.
Acrylic resin holds up well in vanity use and cleans easily with standard bathroom cleaning products. It is lighter than stone composite, which can simplify handling and installation, and the matte finish resists showing minor surface scuffs that a high-gloss finish would make more visible.
Choose this sink when the project calls for a matte white vanity bowl that meets accessibility standards, fits any countertop material, and keeps the bath palette cohesive without demanding attention.
