The Karran Q-309-GR is a single-bowl undermount vanity sink in gray quartz composite, sized for a 24-inch or wider vanity cabinet and designed to mount beneath laminate, solid surface, or granite countertops.
Gray is one of the most common anchors in contemporary and transitional bathroom design, sitting comfortably alongside white, charcoal, wood tones, and brushed metal hardware. This sink in gray quartz composite fits that palette without demanding a matching countertop color, so it works as well in a light marble-look laminate vanity as it does under a dark granite slab. For designers specifying a full bath package or homeowners updating a powder room, the neutral gray keeps future finish changes from forcing a sink replacement.
The bowl is quartz composite, an engineered material that combines natural quartz with a resin binder to produce a dense, consistent surface. The gray finish runs through the material rather than sitting as a surface coating, which means chips and scratches expose the same color underneath. The matte character of the quartz surface keeps the finish from clashing with polished or brushed hardware and keeps water spots less visible than they would be on a high-gloss basin.
This sink is for vanity installations where the countertop is being fabricated or replaced, not dropped into an existing cutout from a previous sink. It undermounts beneath laminate, solid surface, or granite, and needs at least a 24-inch cabinet to carry the 20-inch bowl properly. Contractors building out a bathroom from scratch and designers specifying a complete vanity package will find the straightforward sizing and broad countertop compatibility easy to work with. Confirm the drain rough-in and drain hardware against the 1-3/4 inch drain opening before ordering.
No. This is an undermount sink only. It mounts beneath the countertop so the rim is not visible from above.

No. This sink is not ADA compliant.
Choose the Q-309-GR when the vanity design calls for a neutral that holds its own across finishes, materials, and styles without drawing attention away from the rest of the room.
