A Gray Quartz Undermount Sink for Everyday Kitchen Work

This Karran 60/40 double-bowl quartz sink mounts beneath quartz, granite, or solid surface countertops and delivers two unequal basins in a warm gray finish that blends naturally into a range of kitchen palettes.

Key Features

• 60/40 double-bowl configuration gives a larger primary basin and a smaller secondary basin in a single 32-inch footprint.
• Gray quartz composite construction built from a dense quartz-and-resin material through and through.
• Undermount installation into granite, quartz, or solid surface countertops, with a 36-inch minimum cabinet width required.
• 9-inch inside depth on both bowls for clearing tall pots and stacking dishes without overflow.
• 3-1/2-inch drain openings sized for standard basket strainers and disposal flanges.
• IAPMO certified to confirm the sink meets applicable plumbing standards.

Two Bowls, Two Jobs

The 60/40 split makes this sink work the way most kitchens actually run. The larger left bowl handles the main wash load, soaking a sheet pan or a cutting board without filling the entire sink. The smaller right bowl stays open for rinsing, a drying rack, or a colander while the other side is in use. Both bowls share the same 9-inch depth, so neither one is a compromise on capacity. Mounting beneath the counter keeps the work surface continuous from counter edge to bowl wall, with no rim to trap debris or complicate a wipe-down.

Gray Quartz That Holds Up

The sink body is quartz composite, a material that carries its gray color through the entire body rather than as a coating over a neutral base. That matters in a working sink because chips and scratches do not expose a different color underneath. The matte gray surface is non-porous, which keeps food residue from bonding and makes the bowl easier to clean after heavy use. The finish reads as a warm neutral, sitting between a stark white and a deep charcoal, and it coordinates with stone countertops, stainless appliances, and natural wood cabinet finishes without competing with any of them.

Where This Sink Fits

This is a sink for a primary kitchen installation where the counter is being fabricated new or replaced. It is undermount only and is not designed to drop into an existing cutout left by a different sink, so it suits a remodel where the countertop is part of the scope or a new-build kitchen. The 36-inch minimum cabinet width is a hard fitment requirement, and the 32-inch overall length means it clears that width with a few inches to spare on each side. It is a practical choice for a household that cooks regularly and wants separate bowls without taking on a wider cabinet footprint, and for a designer or cabinet shop specifying a coordinated gray palette where a stark black or bright white sink would read as a mismatch.
