    Description

    Karran QARWS-740-BI Workstation Sink Function

    Karran QARWS-740-BI workstation sink is a 34 inch wide by 21-1/4 inch deep single bowl quartz apron front farmhouse sink, so it provides a generous work area while fitting a typical kitchen footprint. The sink has a shorter 6-1/2 inch apron, which lets it retrofit into a standard 36 inch wide sink base cabinet where full-height aprons would interfere with existing doors or face frames. It is made from 80% natural quartz crystals and pure acrylic resin, creating a dense composite that supports everyday kitchen use. The quartz material is described as extremely stain, scratch, abrasion and impact resistant, which helps the bowl handle heavy pots and routine cleaning without cosmetic damage. The durable quartz is completely non-porous, preventing the spread of germs and bacteria by not absorbing moisture into the surface. UV stabilization keeps the color looking like new for decades, preserving the bisque finish in normal light exposure.

    Workstation Quartz Farmhouse Details That Matter

    • The sink is designed as a single bowl apron front farmhouse workstation, so it combines apron styling with a unified basin that suits washing larger cookware without center-divider interference.
    • External dimensions are given as 34 inches wide by 21-1/4 inches deep, with all external dimensions approximate to 1/4 inch, which helps during cabinet and countertop layout when planning cutouts or clearances.
    • The 6-1/2 inch shorter apron design allows retrofit into a standard 36 inch wide sink base cabinet, supporting upgrades in existing kitchens without rebuilding the sink base face.
    • The sink is designed for installation under granite, quartz and solid surface countertops, aligning it with typical premium countertop materials used in many kitchen remodels and new builds.
    • The material is heat safe up to 535 F and can withstand rapid changes in temperature from hot and cold water, which supports handling hot pans and fluctuating water temperatures during normal kitchen tasks.
    • The quartz material absorbs vibration and minimizes noise when in use, which reduces sound transfer into the cabinet when water is running or cookware is placed in the bowl.

    Installation Fit For Retrofit Apron Front Use

    This quartz apron front sink is designed for installation under granite, quartz and solid surface countertops, so its edges are intended to support an undermount configuration with rigid tops. The shorter 6-1/2 inch apron height is engineered to fit into a standard 36 inch wide sink base cabinet, helping the front panel align with existing cabinet faces in retrofit situations. The rear drain location leaves more room in the cabinet below, which can simplify routing for waste lines inside typical 36 inch bases. All external dimensions are approximate to 1/4 inch, giving an allowance band that supports real-world cabinet openings and countertop cutouts without demanding exact to-the-millimeter fits.

    Using This Quartz Farmhouse Workstation Sink On The Job

    Where This Quartz Workstation Sink Excels

    This Karran quartz farmhouse workstation sink is part of a quartz sinks product class, so it is purpose-built for kitchen and bath cabinet applications where an apron front aesthetic is wanted. The 9 inch deep bowl provides plenty of room to accommodate all cookware, giving depth for soaking pans and stacking dishes during cleanup. A rear drain location leaves more room in the cabinet below, allowing space for simplifying trap layout or positioning other under-sink components. The quartz material absorbs vibration and minimizes noise when in use, which helps when placing heavy items into the bowl or running high-flow faucets. UV stabilization keeps the bisque color looking like new for decades, supporting long-term visual consistency in an installed run of cabinets and tops.

    Details Supporting Repeatable Retrofit Installations

    The sink is specifically described with a shorter 6-1/2 inch apron designed to be able to fit into a standard 36 inch wide sink base cabinet, which is critical when replacing an existing sink in a fixed cabinet layout. Being designed for installation under granite, quartz and solid surface countertops indicates the rim geometry and load path match these rigid materials, supporting clean undermount reveals. All external dimensions are approximate to 1/4 inch, providing a stated tolerance range that helps during cabinet modifications or template work. The construction from 80% natural quartz crystals and pure acrylic resin yields a durable, completely non-porous surface that prevents the spread of germs and bacteria, which matters when a kitchen sink is in constant contact with food and rinse water. The material is extremely stain, scratch, abrasion and impact resistant, offering a work surface suited to frequent pan movement and utensil contact. The heat safe rating up to 535 F and ability to withstand rapid changes in temperature from hot and cold water support normal kitchen workflows where hot cookware and cold rinses happen in quick succession.
