A Grey Quartz Undermount Sink Built for Everyday Kitchen Work

The Karran Q-340-GR is a single-bowl undermount quartz kitchen sink in Grey, sized to fit a 33-inch minimum base cabinet and designed to mount beneath laminate, solid surface, or granite countertops.

Key Features

• Single large bowl with 28-3/8 inch interior length and 9-inch depth for generous, unobstructed workspace.
• Grey quartz composite body made from a dense blend of natural quartz and acrylic resin.
• Undermount installation compatible with laminate, solid surface, and granite countertops.
• cUPC and IAPMO certified to meet North American plumbing standards.
• 3-1/2 inch drain opening for standard kitchen drain and disposal hardware.
• Requires a minimum 33-inch base cabinet for proper fit and support.

A Single Bowl That Handles Full Loads

One uninterrupted basin makes it easy to fill a large stock pot, soak a sheet pan, or wash oversized cutting boards without splitting the space. The 9-inch bowl depth keeps water contained and gives enough room to work comfortably without reaching over a divider. For kitchens where a second bowl is rarely useful and a larger single space is a better trade, this configuration delivers it cleanly.

Grey Quartz Composite: the Material and What It Means

The sink is made from natural quartz blended with acrylic resin, a dense composite that gives the bowl consistent color all the way through and a surface that holds up to the normal punishment of a working kitchen. The Grey finish reads as a true neutral, sitting comfortably alongside white, charcoal, or warm-toned countertop surfaces without competing. Because the color runs through the material rather than sitting on top, small nicks at the bowl edge stay inconspicuous. Mounting beneath the counter keeps the countertop surface unbroken to the bowl rim, which makes daily cleanup straightforward.

Where This Sink Fits Best

This is a good choice for a primary kitchen sink in a layout built around a 33-inch base cabinet, particularly in kitchens where the countertop material is laminate, solid surface, or granite and the goal is a clean, flush countertop-to-bowl transition. Designers specifying a neutral palette that bridges warm and cool tones will find Grey easier to work with than a stark white or a dark black finish. Remodelers replacing an existing sink should note that this is an undermount design, which works best when the counter is being fabricated or replaced at the same time. Confirming the cabinet width and countertop material before ordering avoids a mismatch at install.
