A 33-Inch Double Bowl Sink Built for the Everyday Kitchen Work Zone
The Karran QU-720 is a double equal bowl undermount kitchen sink in quartz composite, sized to anchor a full-scale kitchen workspace. Its symmetrical layout and Brown quartz finish make it a practical, long-wearing choice for kitchens that see genuine daily use.
Key Features
• Double equal bowl layout divides the sink into two identically sized basins, supporting wash-and-rinse or wash-and-prep workflows side by side.
• Quartz composite construction combines 80% natural quartz crystals with 20% acrylic resin for a basin that resists scratches, stains, chips, and heat in everyday kitchen use.
• Undermount installation positions the sink beneath the countertop with a clean, wipe-straight-through counter edge and no visible rim from above.
• Brown finish integrates naturally with wood-tone cabinetry, warm stone countertops, and earth-palette kitchen designs.
• 9-inch bowl depth accommodates tall pots, roasting pans, and sheet pans without awkward angling.
Dividing the Work Without Dividing the Space
Two equal bowls let you run a simple, effective two-station setup: soap and hot water on one side, a clean rinse on the other, or one bowl dedicated to prep while the other clears dishes. The symmetrical split is especially useful in kitchens where one cook handles multiple tasks at once, and it keeps the workspace organized without requiring any extra plumbing footprint beyond a standard double-bowl install. Because the bowls are equal rather than offset, there is no wrong side — the layout works equally well for left- and right-handed users and for kitchens where the plumbing comes up center.
Quartz Composite Inside and Out
Quartz composite sinks earn their place in working kitchens because the material holds up where thinner alternatives show wear. The 80% quartz content gives the surface genuine scratch and chip resistance, and the resin binder keeps the finish non-porous so stains from coffee, wine, and food dyes do not penetrate. The Brown colorway runs through the full material depth, so minor surface scuffs do not reveal a contrasting core underneath. Undermount installation in this series places the flat rim beneath the countertop, bonded to the underside with adhesive and mechanical fasteners suited to the countertop material. The faucet and any accessories mount through the countertop itself, since the QU series has no integrated faucet deck.
Where the QU-720 Fits Best
This sink is sized for a 36-inch or larger sink base cabinet, making it a natural fit for a standard full-size kitchen rather than an island bar station or a compact prep area. The Brown quartz finish works hardest in kitchens that already lean warm: honey or walnut cabinetry, soapstone or quartz countertops in earth tones, or tile backsplashes in terracotta and cream. Cabinet shops and installers sourcing for a full kitchen renovation will find it a straightforward undermount specification for granite, quartz, or solid surface countertop installations. Homeowners replacing a worn top mount drop-in should confirm their countertop can accept an undermount before ordering, since the install path requires a finished cutout edge.
Does the QU-720 come with a drain, grid, or mounting clips?
The QU-720 is sold as a bare sink. Drains, bottom grids, and mounting clips are purchased separately. Karran's GR-series grids are matched to specific bowl dimensions, so confirm the bowl size before ordering a grid.
What countertop materials work with this sink?
The QU series undermounts in quartz, granite, and solid surface countertops. It is a standard undermount, not a seamless installation — the countertop edge is finished and the sink rim bonds beneath it. For laminate countertops with a seamless look, Karran's Q Series is the right choice.
Where does the faucet mount on the QU-720?
The QU series has no faucet deck, so the faucet, soap dispenser, and any other accessories mount through drillings in the countertop behind the bowl. Coordinate hole placement with your countertop fabricator before the cutout is made.
Is Brown the same shade across Karran's quartz sink line?
Karran's Brown (BR) quartz color is consistent across the QU, QT, QA, and related series, so it coordinates across sink types if you are specifying multiple bowls in the same space. Always view a physical sample alongside your countertop and cabinetry before finalizing.
A Reliable Centerpiece for a Kitchen That Works Hard
The QU-720 brings together a proven undermount format, a durable quartz composite build, and a warm Brown finish in a size that handles the full range of kitchen tasks. It is straightforward to specify, practical to install in stone and solid surface countertops, and built to stay looking like itself years into daily use.
