    Description

    Karran Q-306-BS Quartz Vanity Sink For Baths

    Karran Q-306-BS quartz vanity sink provides a single bowl oval basin in a compact 19 inch wide by 15 inch deep format, giving bathroom vanities a defined sink area that fits typical residential tops. The internal bowl dimensions of 16-1/2 inches by 13 inches by 6 inches deep create a comfortable washing space while maintaining room on the countertop, which helps when balancing design layouts in tight bath installations. The sink is manufactured from 80% crushed quartz plus 20% acrylic resin, creating a quartz composite structure that supports daily use in bathroom environments. Its bisque finish ties directly to the quartz material color, allowing consistent visual results when coordinating with warm-toned vanity tops. As part of Karran's quartz sinks product class, this model aligns with other quartz-based fixtures in the same project, which simplifies finish matching across multiple bathrooms on a job.

    Quartz Sink Details That Support Bath Projects

    • The external bowl dimensions of 19 inches by 15 inches by 5-1/4 inches set a clear cutout and cabinet planning footprint, which helps installers size vanity tops and cabinets accurately during design and fabrication.
    • The internal bowl dimensions of 16-1/2 inches by 13 inches by 6 inches define usable basin volume, giving trades a predictable space for typical bathroom tasks without oversizing the vanity area.
    • The sink is manufactured from 80% crushed quartz plus 20% acrylic resin, producing a quartz composite body that supports a solid-feeling basin for repeated bathroom use and straightforward integration into higher-end projects.
    • The sink is suitable for undermounting to laminate, solid surface and granite, allowing one basin model to serve across multiple countertop materials and simplifying product selection for mixed-material projects.
    • The completely nonporous surface prevents bacteria build up, which supports hygiene goals in residential baths and reduces concerns about moisture-related staining in the bowl area.
    • The satin finish allows the use of all cleansers, including abrasive scouring pads, giving maintenance teams flexibility when dealing with cosmetic marks from daily use.

    Undermount Installation And Faucet Layout Options

    This quartz vanity sink is suitable for undermounting to laminate, solid surface and granite, so one model can be specified across different top materials within the same project. That suitability lets fabricators plan for a consistent undermount reveal and edge treatment whether the top is laminate, solid surface, or stone, which helps coordinate shop processes. Faucet deck type sinks in this line accept 1 hole, 2 hole and 3 hole faucet setups, so a single sink specification can support different faucet patterns across bathrooms. That faucet flexibility streamlines purchasing for trades managing multiple trim packages, because the same basin format can be paired with single-handle or widespread faucet trims without changing the sink callout.

    Quartz Vanity Sink Performance In Daily Bathroom Use

    Where This Single Bowl Quartz Vanity Sink Fits

    This Karran 19 inch wide by 15 inch deep single bowl vanity quartz sink is sized for bathroom vanities that need a defined oval basin without taking excessive counter width, which suits compact and standard bath layouts. Its internal bowl dimensions of 16-1/2 inches by 13 inches by 6 inches deep create a functional depth for face washing and routine bathroom tasks while preserving counter space around the bowl for toiletries. Being suitable for undermounting to laminate, solid surface and granite allows the sink to move between entry-level laminate installations and higher-end solid surface or granite projects under one model number, which keeps specifications consistent when property grades vary. The bisque finish gives designers a warm-toned option that ties into cream or beige top materials, supporting coordinated color schemes in both residential and light commercial bathrooms that use quartz sinks as a visual anchor.

    Details That Support Heat, Cleaning, And Longevity

    This vanity sink is manufactured from 80% crushed quartz plus 20% acrylic resin, creating a quartz composite structure that supports a solid-feeling bowl under daily residential bathroom use. The material is guaranteed not to stain or crack from thermal shock and withstands temperatures of up to 530 degrees F, so brief contact with high-temperature items within typical bathroom scenarios does not compromise the basin. A completely nonporous surface prevents bacteria build up, reducing areas where moisture and contaminants might collect and supporting sanitation goals in multi-user bathrooms. The satin finish allows the use of all cleansers, including abrasive scouring pads, so cleaning staff can select stronger products or pads when addressing marks without being limited to mild agents. A 25 years limited warranty against manufacturer's defects replacement backs the long-term performance of the sink, which supports confidence when specifying it across multiple units in a larger project. Replacement for old WBSC part number KAA-306-WH-55 connects this model directly to an earlier stocking reference, simplifying transitions in existing specification lists.
