Karran QU-720-BL Undermount Sink For New Tops

Karran QU-720-BL undermount sink provides a 33-1/2 inch wide by 20-1/2 inch deep footprint, giving a defined cutout size that helps plan cabinet layout and stone fabrication. The 9 inch external bowl depth supports deeper washing capacity while staying practical for everyday kitchen use. Twin 50/50 bowls deliver two separate work zones, useful for keeping cleaning and prep tasks organized. 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 define real working room in each side, aiding in choosing faucet reach and workflow around the sink. All external dimensions are approximate to 1/4 inch, which gives fabricators a clear tolerance when cutting stone. The sink is classified as a quartz sink, aligning it with quartz-focused kitchens. Its black color supports dark design schemes where visual continuity matters.

Key Quartz Sink Details That Support Work

• The sink is manufactured from 80 percent crushed quartz plus 20 percent acrylic resin, creating a quartz-based structure that supports use in everyday kitchen environments.
• A 1-1/4 inch by 3/4 inch machined resin matrix rim forms a defined mounting edge, which helps stone fabricators achieve a consistent undermount reveal around the sink.
• The bowl surface has a matte finish, giving a non-gloss working area that can visually mute water spots and blend with many countertop textures.
• The waste opening is 3-1/2 inches, matching standard kitchen drain sizing so installers can align it with typical strainer basket and plumbing components.
• This sink may be undermounted to all stone products, giving flexibility to pair it with a wide range of stone countertop materials in a project.

Undermount Installation And Countertop Fit

Undermount installation is required for this sink, directing fabricators to create a cutout that supports mounting below the countertop surface. The sink may not be top mounted, so planning centers on an undermount-only workflow. It can be installed only in new countertops, not in existing countertops with an existing sink cutout, which guides project timing and replacement decisions. This sink may be undermounted to all stone products, so stone shops can work with materials they already fabricate. A 1/8 inch overhang is recommended, providing a target reveal that helps achieve a clean edge, yet the sink can also be flush installed when a different aesthetic is desired. All external dimensions are approximate to 1/4 inch, giving room for practical on-site adjustment within normal fabrication tolerances.

Using This Quartz Sink In Real Kitchens

Where The Karran Quartz Double Sink Fits

This Karran quartz double bowl sink is part of the quartz sinks class, fitting projects that call for a quartz-based basin rather than metal. Its 33-1/2 inch by 20-1/2 inch external size suits kitchen layouts designed around a wider sink run. The twin 50/50 bowls provide equal compartments, which supports workflows that separate washing and rinsing or cleaning and prep. External and internal depths of 9 inches give bowl capacity that can comfortably handle pots and pans. The black finish supports designs using dark stone products, helping the sink visually coordinate with black or contrasting countertops. Because it may be undermounted to all stone products, this sink aligns especially well with granite, quartz, and similar stone installations in residential or light commercial kitchens.

Details That Support Consistent Install Results

The 1-1/4 inch by 3/4 inch machined resin matrix rim creates a precise edge that helps stone fabricators route or cut matching openings for repeatable undermount results. An undermount-only design focuses installation steps on one method, which streamlines shop procedures. The 3-1/2 inch waste opening is sized for standard drain fittings, reducing selection complexity when pairing it with strainer baskets and plumbing. A recommended 1/8 inch overhang gives installers a consistent target reveal that looks clean and helps control water flow toward the sink. Flush installation is also supported, so designers can specify a zero-reveal edge when that detail better matches the project. All external dimensions being approximate to 1/4 inch allow fabricators to work within practical tolerances while still hitting the intended layout and reveal.
