Karran QU-690-WH undermount sink is a quartz single bowl sink designed for bar or prep applications where a compact, square bowl is needed. Its external bowl dimensions of 16-5/8 by 16-5/8 inches define the cutout and cabinet planning, helping installers size layouts accurately. Internal bowl dimensions of 14 by 14 by 8-1/4 inches create a deep, usable workspace, giving room for rinsing glassware or handling prep tasks without splashing as easily. The quartz construction provides a solid sink body, supporting a stable mounting surface in solid surface or stone countertops. A white finish allows this sink to coordinate with light-toned tops and fixtures, keeping bar or prep stations visually consistent. All external dimensions are approximate to 1/4 inch, which offers a small tolerance range during layout so installers can work effectively with field conditions.
This Karran quartz white single bowl undermount sink is designed for installation beneath the countertop, so the 16-5/8 by 16-5/8 inch external bowl dimensions guide the sink reveal and cutout sizing. All external dimensions being approximate to 1/4 inch offers a bit of tolerance when coordinating sink edges with countertop openings. The internal 14 by 14 inch bowl size and 8-1/4 inch depth define how far the bowl drops below the counter, which influences drain height and trap configuration during rough-in. A matte bowl surface finish supports a clean transition at the undermount joint, which helps the finished opening look deliberate when paired with stone or solid surface tops. The quartz material provides a stable body around the mounting perimeter, supporting solid attachment to the underside of the counter.
This Karran quartz white single bowl undermount sink fits bar and prep stations that benefit from compact external dimensions of 16-5/8 by 16-5/8 inches, so it can be worked into smaller cabinet runs. The square 14 by 14 inch internal bowl creates a centered work zone that suits straight runs or corner bar layouts, helping with faucet and glass rinsing placement. An 8-1/4 inch bowl depth supports typical bar sink use, giving enough capacity for rinsing pitchers or stacking glassware while staying workable above common drain heights. The matte finish on the sink bowl surface softens reflections, which supports comfortable use in task-lit or backlit bar tops. A white color tone allows the sink to coordinate with many light solid surface or stone counters, supporting cohesive design in residential or light commercial bar layouts.
The externally measured 16-5/8 by 16-5/8 inch bowl size, with all external dimensions approximate to 1/4 inch, gives installers a defined target with some tolerance when aligning the sink under the countertop.

The guarantee that it will not crack from thermal shock and withstands temperatures of up to 530 F supports routine bar and prep workflows, such as exposure to hot cookware or hot water, without damage to the sink structure.
