The Karran Quattro QM172WH is a single-bowl acrylic resin vanity sink in Matte White, designed for above-counter installation into any countertop material and certified ADA compliant.
Matte White is the finish choice when a bathroom needs a clean, cohesive look without the high-gloss contrast that a polished surface introduces. It holds well against matte tile, painted cabinetry, and natural stone countertops, and it reads as intentional rather than simply neutral. An above-counter installation keeps the sink visible as part of the design, so the Matte White surface and the Quattro series profile both contribute to the room rather than disappearing behind a countertop edge. This makes the QM172WH a practical choice for guest baths, primary vanities, and accessible bathrooms where the sink position matters as much as the finish.
The sink is molded from acrylic resin, a material well suited to vanity sinks for its consistent color, smooth surface, and lighter weight compared to composite stone or fireclay. The Matte White surface is part of the material body rather than a topcoat, so the color carries through without requiring a separate painted or applied layer. Acrylic cleans easily with standard non-abrasive bathroom cleaners, and the matte surface keeps minor water marks from showing the way a high-gloss finish does.
This sink fits designers specifying an ADA-accessible vanity where the compliance certification needs to be documented, contractors installing in healthcare, commercial, or multi-family settings with accessibility requirements, and homeowners building or remodeling a bathroom around a Matte White palette. Because it installs above the counter into any countertop material, it works whether the countertop is quartz, laminate, solid surface, or natural stone. The single-bowl layout and compact 18-inch width suit powder rooms and smaller vanity cabinets where a wider sink would leave insufficient counter clearance on either side.
The sink sits on top of the countertop surface rather than dropping through a cutout from above or mounting from below. The rim and bowl are visible, and the countertop supports the sink base. It installs into any countertop material.
The sink is listed as ADA compliant and IAPMO certified. Documentation requests for commercial or permitting purposes should go through your supplier contact.
The drain opening is 1-3/4 inches in diameter. Use a standard vanity drain fitting sized to that opening; the drain is not included with the sink.
Use a non-abrasive cleaner and a soft cloth. Avoid abrasive pads or harsh chemical cleaners that can dull or scratch the acrylic surface.
Choose the Karran Quattro QM172WH when a Matte White, ADA-compliant above-counter sink needs to anchor a clean, accessible bathroom without compromise on material quality or installation flexibility.
