    Karran 20"W x 14"D Q-309 Gray Single Bowl Vanity Quartz Sink - Q-309-GR

    Description

    Karran Q-309-GR Vanity Quartz Sink For Baths

    Karran Q-309-GR vanity quartz sink gives you a single bowl vanity solution sized at 20 inches wide by 14 inches deep, so it suits typical bathroom cabinet layouts where a compact, functional bowl is required. As a quartz sink in the Karran quartz sinks class, it uses a quartz construction that supports a consistent, solid surface for everyday use in bathroom environments. The gray finish offers a neutral option that coordinates with a wide range of vanity colors and room designs, so it fits many design schemes without dominating the space. This sink is part of Wurth Baer Supply Companys offering to the woodworking and cabinet industry, aligning with professional cabinet and countertop workflows. The product is identified by manufacturer part number Q-309-GR, which simplifies reordering or referencing when matching this same model on future projects or service calls.

    Quartz Sink Details That Support Job Needs

    • The 20 inch width and 14 inch depth provide a defined vanity sink footprint, which helps plan cabinet openings and counter layouts around a known bowl size for consistent bathroom designs.
    • The single bowl design keeps the basin area uninterrupted, which gives users a straightforward washing area and reduces internal transitions that can catch debris during normal bathroom use.
    • The gray color creates a uniform appearance across the bowl surface, which supports design continuity when pairing the sink with various countertop materials in residential or light commercial bath settings.
    • The product class designation as a quartz sink signals a engineered sink construction, which supports a hard, stable working surface during typical grooming and cleaning tasks at the vanity.
    • The manufacturer part number Q-309-GR ties directly to this specific model, which helps match project documents and simplifies specifying the same sink across multiple vanities in one job.

    Undermount Quartz Sink Fit And Countertop Use

    This quartz sink seamlessly undermounts into solid surface countertops, so the bowl transitions cleanly beneath the counter for a continuous working surface around the opening. It also seamlessly undermounts into laminate countertops, allowing fabrication teams to integrate the sink below laminate decks where a smooth, easy-to-wipe edge around the bowl is desired. In addition, it seamlessly undermounts into stone countertops, so fabricators can set the sink under materials like engineered or natural stone and achieve a flush, uninterrupted counter edge at the cutout. All external dimensions are approximate to 1/4 inch, which provides a defined tolerance band that matters when fabricators plan cut sizes and clearances around the sink body during layout and installation.

    Where This Karran Quartz Sink Fits Best

    Bathroom Vanity Installations Using Quartz Sink

    This Karran 20 inch wide by 14 inch deep vanity quartz sink suits bathroom vanity applications where a single bowl layout is preferred, such as guest baths or master vanities using individual sinks. As a quartz sink in the sinks and accessories category, it works within typical cabinet and countertop assemblies used by woodworking professionals, aligning with common vanity cabinet depths. The seamless undermount capability into solid surface, laminate, and stone countertops means the same model can be specified across different counter materials on one project, which keeps the visual transition from counter to bowl consistent from room to room. The gray color supports bathroom schemes that use neutral or contrasting tops, allowing designers and installers to repeat this sink across multiple baths while maintaining a coordinated, steady look.

    Details That Support Repeatable Fabrication Results

    The ability to seamlessly undermount into solid surface countertops gives fabricators a clear sink choice when routing or machining those materials, which supports smooth edges and a neat joint line around the bowl for a professional finish. Seamless undermounting into laminate countertops helps shops working with laminate decks maintain a clean, integrated sink appearance, which can reduce visual joints at the edge of the cutout. When used with stone countertops, the same seamless undermount feature allows stone fabricators to polish or finish the cut edge knowing the sink will sit cleanly beneath, helping deliver a crisp reveal at the counter opening. All external dimensions being approximate to 1/4 inch sets an expectation of slight dimensional variation, which fabricators can factor into cutout planning so the sink body seats properly while still achieving the intended undermount appearance across multiple installations.
