Karran QT-721-GR quartz sink provides a 34 inch wide by 22 inch deep top mount double bowl layout, so installers get a defined footprint that fits standard kitchen sink cutout planning while offering generous working space at the countertop. The 60/40 double-bowl configuration uses one larger and one smaller bowl, giving room for washing in the big bowl while reserving the smaller bowl for rinsing or other prep tasks during daily kitchen use. External bowl depth of 9 inches creates a deep working area, which helps contain splashes while handling larger pots and pans. Internal large bowl dimensions of 17-5/8 inches by 17-1/2 inches by 9 inches give a square, usable basin that supports everyday cleaning tasks. Internal small bowl dimensions of 11-1/8 inches by 16-1/8 inches by 9 inches supply a compact second basin, useful when a separate space is needed without enlarging the overall sink footprint.
The QT-721-GR is suitable for top mounting into any type of countertop, so it can be used with a range of counter materials without changing the basic mounting method. This drop-in style lets the rim sit on the counter, creating a defined perimeter that simplifies setting the sink into a prepared cutout. All faucets must be sink mounted, which directs drilling and layout to the sink deck rather than the countertop, helping installers coordinate faucet hole placement directly with the sink position. The requirement of no undermounting keeps this model in a single installation category, which streamlines planning for cutout size, support, and sealing around the top mount rim.
The large bowl size of 17-5/8 inches by 17-1/2 inches by 9 inches provides a primary workspace that suits scrubbing larger pans or stacking dishes, so one side can handle heavier cleaning tasks. The smaller 11-1/8 inches by 16-1/8 inches by 9 inches bowl serves as a secondary station, allowing separation of rinsing, food prep, or soaking without interfering with the main wash area. The 34 inch by 22 inch external footprint keeps both bowls within a standard range for many kitchen cabinet layouts, which helps align the sink with base cabinetry and nearby appliances. Heat resistance up to 530 degrees F allows contact with very hot water or brief placement of hot cookware in the basin, supporting typical kitchen workflows where items move quickly from stove or oven to the sink. Scratch and chip resistance in the quartz material helps the sink maintain its working surface as pots, utensils, and dishes contact the bowls repeatedly during everyday use.
The non-porous surface that prevents bacteria build-up keeps contaminants at the surface, so normal cleaning removes residue without needing deep treatment of the material. Uniform gray color throughout the quartz means minor surface wear does not expose a different substrate color, supporting a consistent appearance after years of use in an active kitchen. Quartz construction that combines natural and man-made materials gives the sink a solid, dense feel, which supports a stable base for dish racks or strainers resting in the bowls. Availability of the sink series in white, bisque, black, brown, concrete, and grey helps designers keep the basin visually tied to other fixtures, which matters when coordinating full kitchen projects. All external dimensions being approximate to 1/4 inch provides a tolerance reference that installers can factor into cutout planning, supporting accurate fitting of the top mount rim against the countertop.
The Karran QT-721-GR quartz sink has external bowl dimensions of 34 inches by 22 inches by 9 inches, giving installers a defined footprint for planning the countertop cutout and cabinet space.
The large bowl measures 17-5/8 inches by 17-1/2 inches by 9 inches, and the small bowl measures 11-1/8 inches by 16-1/8 inches by 9 inches, providing a 60/40 working layout.
The QT-721-GR quartz gray double bowl sink is suitable for top mounting into any type of countertop, so it is used as a drop-in unit with the rim resting on the surface.
