Karran Quartz Workstation Sink For Drop-In Kitchen Installations
The Karran QTWS-875 is a large single-bowl quartz workstation sink that drops into a standard countertop cutout and turns it into a dedicated prep station. The integrated ledge keeps cutting boards, colanders, and drying accessories positioned directly over the bowl, clearing counter space for the rest of the workflow. White quartz composite construction blends into bright, light-forward kitchens while standing up to the demands of daily cooking prep.
Key Features
• Integrated workstation ledge supports sliding accessories over the bowl so prep and drying happen without taking up counter space.
• Top mount / drop-in installation fits into an existing or new countertop cutout across laminate, solid surface, stone, and quartz surfaces.
• Quartz composite construction (80% natural quartz, 20% acrylic resin) delivers high resistance to scratches, stains, chips, and heat in daily kitchen use.
• Extra-large single bowl accommodates full sheet pans, oversized pots, and large cutting boards without a center divider getting in the way.
• White finish coordinates with white cabinetry, light-toned countertops, and bright kitchen hardware.
• Accessories included: the sink ships with a bottom grid, basket strainer, cutting board, colander, drying rack, and Luster Pro sink oil.
A Full Prep Station, Not Just a Sink
The workstation ledge built into the QTWS-875 rim is the reason this sink changes a kitchen's workflow. Slide the cutting board across the ledge and trim straight into the colander. Move the drying rack into position while dishes air-dry over the bowl. Roll it aside when the bowl is needed at full depth. Nothing sits on the counter because everything parks over the water. That shift is especially useful in kitchens where counter real estate is limited or already taken by appliances. The included accessories are sized for this sink specifically, so fit is exact rather than improvised.
Material Built for the Work
Quartz composite at this blend — 80% natural quartz crystals bound in 20% acrylic resin — produces a bowl that handles the typical abuse of a busy kitchen sink without showing it. The material is highly scratch, stain, chip, and heat resistant, which matters on a surface where knife handles, cast iron, and boiling water all make regular contact. The White finish is non-porous, so it does not harbor bacteria or absorb odors, and routine cleaning with mild soap keeps it looking clean over time. Quartz composite also runs quieter underfoot than thin stainless, so filling a full pot is less disruptive in an open-plan kitchen.
Who Reaches for This Sink
Cabinet shops and remodeling contractors specifying a top mount installation will find the QTWS-875 straightforward: it drops into the cutout, clips from below, and the ledge system is ready to go. No special countertop material is required — laminate, solid surface, stone, and quartz all work with a standard drop-in method. Homeowners upgrading a kitchen who want to keep their existing countertop but gain real prep functionality get that here, without committing to an undermount install. Designers specifying kitchens where white surfaces anchor the palette can carry the sink's White finish into the broader color plan with confidence, knowing the quartz holds its color and resists yellowing under normal use.
Does the top mount installation limit which countertop materials I can use?
No. Because the sink rests on its rim and clips from beneath, it works with laminate, solid surface, stone, quartz, and most solid countertop materials. The rim covers the cut edge, so a perfectly finished cutout is not required.
What accessories ship with this sink?
The QTWS-875 includes a bottom grid, basket strainer, cutting board, colander, drying rack, and Luster Pro sink oil. No faucet is included; this is a PK1-style bundle without the faucet tier.
Is a drain assembly included?
The basket strainer ships with the sink. A separate drain tailpiece or drain assembly may be needed depending on the existing plumbing configuration — confirm with the plumber or installer before the job.
Can I use third-party accessories on the workstation ledge?
The ledge and accessories are sized for the QTWS-875 specifically. Accessories from other families may not span or seat correctly on this model's ledge. Use the included set or accessories confirmed to fit the QTWS workstation series.
How do I care for the White quartz composite finish?
Mild dish soap and warm water handle everyday cleaning. The included Luster Pro oil is formulated to refresh and protect the quartz surface. Avoid abrasive scrubbers and harsh chemical cleaners, which can dull the finish over time.
One Sink That Does More
The QTWS-875 brings a complete prep-and-wash station to any kitchen that can accept a standard drop-in sink, with the quartz durability and White finish to match the way the space looks and the way it gets used.
