A Karran Quartz Undermount Sink for Kitchens That Call for Grey

The Karran Q-350-GR is a 50/50 equal double-bowl undermount sink in grey quartz composite, sized for a 33-inch or wider base cabinet and designed to mount beneath granite, solid surface, or laminate countertops.

Key Features

• Equal double-bowl configuration splits the basin evenly for separating washing, rinsing, or prep tasks.
• Grey quartz composite construction built from quartz and acrylic resin for a dense, consistent body.
• Undermount installation into granite, solid surface, or laminate countertops only.
• 8-1/2 inch bowl depth handles large cookware without water spilling over the rim.
• cUPC and IAPMO certified for compliance with North American plumbing standards.
• 3-1/2 inch drain opening accepts standard sink strainers and basket assemblies.

Two Equal Bowls for a Split-Task Kitchen Workflow

A 50/50 double-bowl layout gives each task its own space. One side can soak a stock pot while the other stays clear for rinsing vegetables or staging clean dishes. The undermount installation keeps the counter surface unbroken to the bowl edge, which makes sweeping food scraps straight into the sink a natural part of the prep routine rather than an extra step. At 8-1/2 inches deep, each bowl handles tall items without crowding the workflow on the opposite side.

Grey Quartz Composite Inside and Out

The Q-350-GR is made from quartz blended with acrylic resin, a composite that carries the grey color uniformly through the body rather than as a surface coating. The matte grey tone sits in a middle register between cooler and warmer neutrals, which means it reads naturally with white, cream, or darker cabinet palettes without pulling hard in any direction. Quartz composite resists the everyday thermal shifts of kitchen use and holds its surface through normal cutting-board, cookware, and cleaning routines.

Where This Sink Fits

This sink is the right choice for a kitchen where grey is already doing work in the palette, whether in the cabinetry, the countertop, or the tile. Designers specifying a coordinated, tone-on-tone kitchen and homeowners remodeling around a grey stone or quartz countertop will both find the finish easier to work with than a bright white or high-contrast black bowl. Because it is an undermount-only sink, it needs to go into a new countertop fabrication, not dropped into an existing cutout. Confirm the base cabinet measures at least 33 inches wide and check the 32-1/2 by 19 inch footprint against the countertop layout before ordering.
