24-Inch Undermount Sink For Compact and Secondary Kitchen Stations
The Karran QU-820 is a 24-3/8 by 19-1/8 by 9-inch single bowl quartz undermount kitchen sink, sold as a kit that includes stainless steel basket strainers, a bottom grid, and Luster Pro oil. Built from 80% natural quartz and 20% acrylic resin in White, it installs beneath granite, quartz, and solid surface countertops for a clean, rim-free wash station.
Key Features
• Quartz composite construction delivers a surface that is highly scratch, stain, chip, and heat resistant for lasting performance at the wash station.
• Undermount installation positions the sink beneath the countertop so the surface wipes clean with no exposed rim catching debris.
• 9-inch bowl depth provides generous clearance for pots, cutting boards, and oversized cookware in a compact footprint.
• Kit includes basket strainers, bottom grid, and Luster Pro oil so the sink arrives ready to install and put to work.
• White finish coordinates cleanly with white or light-toned countertops and cabinetry across a wide range of kitchen styles.
Where a 24-Inch Single Bowl Fits the Job
At just over 24 inches wide, the QU-820 occupies a footprint that most standard single-basin cabinets can accommodate without modification. That makes it a practical choice for secondary prep stations on an island, bar sinks in a butler's pantry, or any kitchen where the primary sink is already set and a second wash point is needed nearby. Smaller kitchen layouts that cannot fit a 30-inch or 33-inch basin without crowding adjacent cabinetry also benefit from this size, without giving up the 9-inch bowl depth that handles serious prep work. Because the faucet mounts through the countertop rather than through a sink deck, the installer has full flexibility on placement and hole count.
Quartz Composite Construction and White Finish
The 80% quartz and 20% acrylic resin composition resists the daily accumulation of scratches, stains, chips, and heat that a busy wash station produces. White is a neutral that pairs with solid surface, white quartz, and light laminate counters, and the matte, stone-like texture holds its appearance without showing every water spot. Because the material is uniform through its thickness, minor surface marks do not expose a different color or substrate underneath. The included Luster Pro oil is formulated for routine care of this material and arrives in the kit so nothing needs to be sourced separately for the first service.
Right For Compact Kitchens and Renovation Installs
Cabinet shops fitting out smaller kitchen layouts, contractors sourcing a secondary prep sink, and homeowners renovating a tight galley or island all find the QU-820's 24-inch width a useful intermediate size. It suits renovation projects where the counter is already cut or where expanding to a larger cutout is not practical. Designers specifying a clean, understated aesthetic in White will find the undermount installation delivers the uninterrupted counter surface most clients expect. The kit format means the install is not waiting on a separately ordered grid or strainer.
Frequently Asked Questions
Does the QU-820 work with laminate countertops?
The QU Series is designed for undermount installation in granite, quartz, and solid surface countertops. If your project uses laminate, look to Karran's Q Series, which is documented for seamless undermount installation in laminate using a bevel-bit method.
Is a template included for cutting the countertop?
No template or mounting clips are included with the QU-820. Most fabricators use the actual sink as the cutout guide, or work from a DXF file available for CNC use. Confirm your fabrication method before cutting.
Where does the faucet mount on this sink?
The QU-820 has no integrated faucet deck, so the faucet mounts through drillings in the countertop directly behind the bowl. This gives the installer control over hole count and placement to match any single-hole or widespread faucet configuration.
What is included in the kit?
The PK1 kit includes stainless steel basket strainers, a bottom grid, and Luster Pro oil. A drain assembly is not included and must be ordered separately.
Can the bottom grid scratch the quartz surface?
The included stainless steel grid is designed to rest in the bowl and protect the quartz bottom from direct contact with cookware and utensils. The quartz composite is highly scratch resistant, and the grid adds a practical layer of protection during heavy prep use.
A Complete Kit Ready For the Install
The QU-820 brings together an undermount quartz bowl, grid, strainers, and care oil in a single order, so a compact, clean-surfaced wash station comes together without tracking down components from multiple sources.
