The Karran Quattro QM178WH is a 16-inch square single-bowl acrylic vanity sink finished in Matte White, designed for above-counter installation into any countertop material and certified ADA compliant.
Matte White is the finish that disappears into a design without calling attention to itself — and in a bath, that is often exactly right. It pairs with subway tile, concrete, marble-look quartz, and painted vanity cabinets without fighting any of them for attention. The Quattro's square shape reinforces that restraint: no curves to introduce a style conflict, just a clean perimeter that works whether the rest of the space is transitional, modern, or minimalist. For a powder room that needs to look considered without looking decorated, this sink earns its spot on the counter.
The sink body is acrylic resin, a material that stays comfortable to the touch in a way that stone-composite and metal alternatives do not — especially in a bath where bare hands and bare skin are the norm. The matte surface finish keeps water spots and minor smudges less visible than a polished or glossy acrylic would, and the 4-1/2 inch bowl depth gives enough capacity for rinsing and washing without making the sink feel disproportionately deep on a compact vanity counter.
ADA-compliant bath layouts have specific clearance and height requirements, and specifying a sink that carries the certification takes one variable off the checklist. This sink supports that process with its IAPMO certification and ADA compliance confirmed. The 16-inch square format also suits powder rooms and secondary baths where counter space is limited — smaller than most kitchen prep sinks, but properly sized for a single-user vanity. Above-counter installation opens it up to any countertop material on site, so the countertop selection is not constrained by the sink.
Yes. This sink is designed for above-counter installation into all countertop materials, including laminate, so it does not require a stone or solid-surface counter the way an undermount sink does.
The drain opening is 1-3/4 inches. Confirm your drain or pop-up assembly matches that opening before ordering.
The sink is listed as ADA compliant and carries IAPMO certification. For projects where documentation is required, confirm those credentials with Karran directly.
Acrylic resin is smooth and non-porous, so standard bathroom cleaners work well. Avoid abrasive scrubbers, which can dull a matte surface over time.
This Karran Quattro sink brings a square, 16-inch Matte White basin to above-counter vanity installs where accessibility compliance, countertop flexibility, and a finish that blends into the design all matter.
