A Top Mount Quartz Kitchen Sink Built for Retrofit-Friendly Installation
The Karran QT-722 is a large single bowl quartz composite kitchen sink that installs from above into virtually any countertop material, making it a straightforward fit for existing kitchens and new builds alike. At 34 by 22 by 9 inches, it delivers a generous, uninterrupted basin in Gray — and ships as a complete kit so the first-day install list is shorter.
Key Features
• Top mount installation drops into the cutout from above and is compatible with laminate, stone, solid surface, and tile countertops.
• Quartz composite construction combines 80% natural quartz crystals and 20% acrylic resin for a basin that is highly resistant to scratches, stains, chips, and heat.
• Large single bowl provides an uninterrupted 34-inch workspace, accommodating sheet pans, stockpots, and oversized cookware without a divider in the way.
• Gray finish offers a neutral, contemporary tone that coordinates with a wide range of cabinet and countertop colors.
• Kit includes basket strainer, bottom grid, and Luster Pro oil, so key accessories arrive with the sink.
Where the QT-722 Earns Its Place
Top mount installation is the most versatile path in kitchen sink work. Because the rim rests on the countertop and covers the cut edge, it tolerates laminate installations that undercut sinks cannot, and it retrofits cleanly into an existing cutout without reworking the countertop surround. That makes the QT-722 a practical choice for a kitchen refresh where the counters are staying, for a laminate build where a seamless-mount method is not on the table, or for any project where the goal is a clean result without specialized fabrication. The 9-inch bowl depth handles the volume of a main wash station, and the single bowl layout maximizes usable space in that 34-inch footprint — no divider splitting capacity in half.
Quartz Composite Built to Take Daily Use
The bowl is made from 80% natural quartz crystals bound in 20% acrylic resin, a composition that resists the everyday punishment of a kitchen sink station: scratches from pots and utensils, staining from coffee or wine, chipping from dropped tools or heavy cookware, and heat from pans pulled straight off the burner. The Gray colorway runs through the material rather than sitting on the surface, so minor scuffs do not expose a different-colored substrate beneath. The matte texture also tends to hide water spots and fingerprints better than a high-gloss bowl, which matters in a hardworking kitchen that does not get wiped down after every use.
The Right Fit for Remodels, Retrofits, and New Laminate Builds
This sink is well suited to cabinet shops building laminate kitchens who want a durable quartz bowl without a seamless fabrication process. It works equally well for contractors replacing an existing drop-in sink — the top mount rim tolerates countertop cut edges in any material, and the standard installation method does not require bevel routing or special adhesives. Homeowners doing a DIY kitchen update will find the installation process familiar: trace the template, make the cutout, set the sink, and clip it from below. The included kit components mean the basket strainer and bottom grid are already matched to the sink and in the box, rather than a separate sourcing step.
Does this sink require any special countertop material to install?
No. The top mount method is compatible with laminate, stone, quartz, solid surface, and tile — the rim covers the cut edge regardless of what the countertop is made from.
Is a faucet included with the kit?
No. The QT-722-GR-PK1 kit includes a basket strainer, bottom grid, and Luster Pro oil. A faucet is sold separately; because the sink has no integrated faucet deck, the faucet mounts through the countertop.
Is a cutout template included?
Check the box contents when the sink arrives. For top mount sinks in this line, confirm the template situation before cutting — using the actual sink as a tracing guide is always the safest fallback.
Can quartz composite sinks be damaged by heat?
The quartz composite material is described by Karran as highly heat resistant. That said, consistently placing very hot cookware directly on the surface is not a practice the manufacturer recommends — use a trivet or allow pans to cool slightly before setting them in the bowl.
What drain size does this sink use?
The QT-722 uses a standard 3-1/2 inch kitchen drain opening. A basket strainer is included in the kit.
One Sink, Ready to Install
The QT-722 in Gray pairs a large, hardworking quartz composite bowl with the simplest installation path in kitchen sinks — drop in, clip down, done — and arrives with the grid, strainer, and care oil already in the box, so the sink is ready to work from the day it goes in.
