A 33-Inch Top Mount Sink Built for the Divided Workflow
The Karran QT-610 is a quartz composite top mount kitchen sink in a large/small bowl configuration, sized at 33 by 22 by 9 inches and finished in Concrete. It drops into a new or existing countertop cutout without requiring dedicated fabrication tools or countertop replacement, making it the practical choice when the goal is a working kitchen upgrade rather than a full countertop build.
Key Features
• Top mount drop-in installation fits new and existing countertops in any material, with the rim sitting above the counter and covering the cut edge.
• Large/small bowl layout separates a primary wash basin from a compact prep or rinse side, keeping tasks from overlapping during busy meals.
• Quartz composite construction combines 80% natural quartz crystals with 20% acrylic resin for a surface that is highly resistant to scratches, stains, chips, and heat.
• Concrete finish provides a warm, muted tone that bridges the gap between industrial-modern and transitional kitchen aesthetics.
• 9-inch bowl depth handles tall stock pots and sheet pans without spillover on the large side.
What the Divided Bowl Configuration Delivers
A large/small bowl sink earns its place in kitchens where cooking and cleaning run at the same time. The larger bowl holds a soaking pot or a rinsing stack of produce while the smaller bowl stays clear for quick rinsing, straining, or holding a colander. That division also makes room for a garbage disposal on the small side without giving up the full depth of the main basin. The SAP description confirms the large bowl on the left and the small bowl on the right as installed, which matches the standard LH/LG, RH/SM orientation for this model.
Quartz Composite Construction and the Concrete Finish
Quartz composite is not a surface coating — it is a through-body material, which means nicks and wear do not reveal a different color beneath. The 80/20 quartz-to-resin ratio gives the bowl the dimensional stability of stone with the slight give needed to resist chipping under impact. In Concrete, the finish reads as a warm neutral gray with subtle texture, a tone that pairs naturally with white cabinetry, greige stone, or darker matte surfaces without committing to the colder look of polished stainless.
Where This Sink Fits Best
This is a straightforward choice for homeowners upgrading an existing kitchen without tearing out the countertop. Because the top mount rim seats over the cutout edge, laminate, tile, butcher block, and solid surface countertops all work without edge finishing. Cabinet shops and remodel contractors will find it fits a standard 36-inch sink base with room to spare. Designers specifying a transitional or soft-industrial kitchen will appreciate that Concrete sits between the warmth of brown quartz and the neutrality of grey, giving flexibility to shift the palette in either direction with accessory choices.
Frequently Asked Questions
Does this sink work on laminate countertops?
Yes. The top mount rim drops over the cutout edge and covers it, so no edge finishing is required. This installation method is compatible with laminate, tile, butcher block, solid surface, and stone countertops.
Which side is the large bowl and which is the small?
As installed, the large bowl is on the left and the small bowl is on the right.
Is a drain or strainer included in the box?
The QT-610 ships as a bare sink. A basket strainer or drain assembly is sold separately and sized to the bowl's drain opening.
Where do the faucet holes go on a top mount quartz sink?
The QT-610 has a faucet deck built into the sink, so faucet holes are drilled through the deck rather than through the countertop behind it. Confirm the number of holes required by your faucet before drilling.
What size base cabinet does this sink require?
With a 33-inch overall length, this sink is designed for a standard 36-inch sink base cabinet. Confirm the cabinet's interior opening against the sink's overall dimensions and cutout requirements before ordering.
A Working Kitchen Upgrade Without a Full Countertop Commitment
The QT-610 in Concrete brings the durability of quartz composite and the efficiency of a divided bowl layout into any kitchen without demanding a countertop replacement, making it one of the most practical paths to a material and workflow upgrade at the same time.
