    Description

    Karran Q-306-BL Quartz Vanity Sink Use

    Karran Q-306-BL quartz vanity sink is a 19 inch wide by 15 inch deep single bowl that creates a defined basin size for bathroom vanity layouts, which helps plan cabinet openings and clearances. The internal bowl dimensions of 16-1/2 inches by 13 inches by 6 inches give a usable washing area that balances capacity with restraint in smaller vanity spaces. This sink is suitable for undermounting to laminate, solid surface and granite, so it can be specified across different countertop materials on the same project without changing the sink model. The black quartz material delivers a consistent color tone that supports coordinated bath designs where the sink needs to visually tie into darker tops or fixtures. As part of Karran's quartz sinks product class, this model provides a defined solution for vanity applications where an undermount oval bowl is required.

    Quartz Sink Details That Support Daily Use

    • The external bowl dimensions of 19 inches by 15 inches by 5-1/4 inches set the overall footprint, which guides cutout planning and ensures the sink nests correctly within standard vanity cabinet widths.
    • The internal bowl size of 16-1/2 inches by 13 inches by 6 inches defines the working depth and width, giving enough room for typical bathroom tasks while helping control water splash and containment.
    • Suitability for undermounting to laminate, solid surface and granite creates flexibility in countertop selection, allowing the same sink model to be used across different materials on a job.
    • Manufacture from 80% crushed quartz plus 20% acrylic resin produces a composite structure that supports a solid-feeling basin important for long-term everyday bathroom use.
    • The satin finish allows the use of all cleansers, including abrasive scouring pads, which simplifies cleaning choices in environments where tougher cleaning methods are sometimes needed.
    • A completely nonporous surface prevents bacteria build up, which supports hygiene expectations in residential and light commercial bathroom settings.

    Undermount Installation And Fit Characteristics

    This vanity quartz sink is suitable for undermounting to laminate, solid surface and granite, so installers can apply consistent mounting techniques across these countertop types. The external dimensions of 19 inches by 15 inches guide the cutout size and positioning, helping align the bowl properly under the faucet set and mirror. The 5-1/4 inch external depth and 6 inch internal depth indicate how far the sink extends below the counter, which matters when planning trap height and drawer clearances. All external dimensions are approximate to 1/4 inch, so layouts can account for this tolerance when coordinating sink location with cabinet framing.

    Applying This Quartz Vanity Sink In Projects

    Where This Black Quartz Vanity Sink Fits Best

    This Karran 19 inch wide by 15 inch deep single bowl vanity quartz sink fits bathroom projects needing an undermount oval bowl with a defined compact footprint. Its suitability for undermounting to laminate, solid surface and granite means it can be used in varied bathroom programs, from laminate-topped vanities to stone or engineered tops, without changing the sink specification. The internal dimensions of 16-1/2 inches by 13 inches by 6 inches provide enough room for washing while staying within the limits of typical 19 to 21 inch vanity depths, which helps maintain storage space in the cabinet below. The black quartz color supports designs that call for contrast against lighter tops or a unified dark scheme where fixtures coordinate with hardware and faucets.

    Details That Support Reliable Undermount Results

    The construction from 80% crushed quartz plus 20% acrylic resin provides a stable composite that supports the sink during undermount installation when it is bonded and braced beneath laminate, solid surface or granite. The guarantee that it will not stain or crack from thermal shock and withstands temperatures of up to 530 degrees F means the material maintains integrity when exposed to typical hot-water bathroom use, which supports confidence during service life. The nonporous surface that prevents bacteria build up also resists fluid penetration at the bowl surface, which supports a clean joint at the counter opening when properly sealed. The satin finish that accepts all cleansers, including abrasive scouring pads, allows maintenance crews or homeowners to use stronger cleaning products on the rim and bowl without changing the sink model choice. All external dimensions being approximate to 1/4 inch informs template and cutout planning so fabricators can allow for small variances while still aligning the sink accurately to the faucet and drain location in the vanity.
