Karran QU-720-GR Undermount Sink For New Countertops

Karran QU-720-GR undermount sink is a quartz gray double 50/50 bowl sink designed for new kitchen countertops where an undermount installation is planned from the start. The external bowl dimensions of 33-1/2 inches wide by 20-1/2 inches deep by 9 inches high define the cutout envelope, so the sink fits standard kitchen base cabinet layouts that can accommodate this footprint. Internal bowl dimensions of 14-3/8 inches by 17-1/4 inches by 9 inches and 14-3/8 inches by 16 inches by 9 inches set the usable space in each bowl, giving installers clear sizing for dish, pot, and pan handling within a double equal configuration. The waste opening of 3-1/2 inches matches common kitchen drain fittings, which simplifies alignment with plumbing components during layout. A quartz gray finish positions this sink visually for projects using stone countertops where a neutral tone is required.

Quartz Double Bowl Details That Support Daily Use

• The sink is manufactured from 80 percent crushed quartz plus 20 percent acrylic resin, which creates a quartz sink structure suited to solid, rigid undermount support beneath stone countertops.
• A 1-1/4 inch by 3/4 inch machined resin matrix rim surrounds the sink, providing a defined bearing surface that supports consistent seating against the underside of the countertop during installation.
• The sink bowl surface has a matte finish, which gives the working area a non-gloss appearance that coordinates with many stone surfaces and helps hide minor water spotting during everyday use.
• The double 50/50 bowl layout creates two equal work zones, so users can dedicate one bowl to washing and the other to rinsing or prep work within the defined internal dimensions.
• All external dimensions are approximate to 1/4 inch, giving fabricators a clear tolerance range to follow when creating cutouts or digital files around the specified 33-1/2 by 20-1/2 profile.

Undermount Installation And Countertop Fit Considerations

Undermount installation is required for this sink, so the bowl hangs from the underside of the countertop rather than resting on top, producing a clean edge at the cutout. The sink may not be top mounted, which directs fabricators and installers toward an undermount-only design when planning cabinet and countertop coordination. This sink may be undermounted to all stone products, which allows it to pair with a range of stone countertop materials in kitchen projects. A 1/8 inch overhang is recommended at the countertop edge above the sink, giving a small reveal that helps control water at the rim, but the sink can also be flush installed for a different edge detail using the same machined rim surface.

How This Quartz Double Bowl Sink Fits Real Projects

Where This Double Equal Bowl Undermount Sink Works

This quartz gray double 50/50 bowl undermount sink is intended for new countertops, so it fits remodels or new builds where the fabricator is cutting stone specifically for this unit. Because it can only be installed in new countertops and not in existing countertops with an existing sink cutout, it is suited to projects where cabinets, stone, and plumbing are being coordinated together from the layout stage. The ability to undermine to all stone products means it integrates into kitchens using a variety of stone countertop choices while still relying on the same rim and bowl geometry. The equal internal bowl sizes, at 14-3/8 inches wide in each bowl with the specified depths, define work zones for kitchens that need balanced left and right bowl functionality. A quartz gray color helps the sink visually align with many stone shades in residential or light commercial kitchens.

Details That Support Accurate Fabrication And Installation

The 1-1/4 inch by 3/4 inch machined resin matrix rim provides a consistent, machined edge for fabricators, which aids in setting a uniform reveal or flush edge along the full perimeter during undermount installation. External bowl dimensions of 33-1/2 inches by 20-1/2 inches by 9 inches, held to approximately 1/4 inch, give counter shops clear targets when programming CNC equipment or laying out manual templates around cabinet and clearance constraints. Internal bowl dimensions of 14-3/8 inches by 17-1/4 inches by 9 inches and 14-3/8 inches by 16 inches by 9 inches inform drain placement, faucet offset planning, and workflow design from left to right. The waste opening of 3-1/2 inches ties directly into standard kitchen drain sizing, so plumbing rough-ins can be aligned to that center point. Digital templates for CNC machines are available at the manufacturer website, which supports repeatable cutout shapes and rim reveals around the sink geometry. The matte finish on the bowl surface offers a consistent visual reference line along the cut edge of the stone, helping installers line the sink to the opening during final positioning.
