A White Quartz Bar and Prep Sink for a Clean, Finished Look

The Karran Q-315 is a single-bowl undermount bar and prep sink in white quartz composite, sized for bar stations, kitchen islands, and dedicated prep areas where a full kitchen sink is too large for the space.

Key Features

• White quartz composite construction delivers a consistent, bright finish from the rim to the bottom of the bowl.
• Single-bowl square layout at 14 inches by 14 inches inside the bowl, giving a clean, symmetrical workspace.
• Undermount installation designed for laminate, solid surface, and granite countertops.
• 8-inch inside bowl depth accommodates deep pitchers, prep bowls, and tall pots without overflow.
• 3-1/2 inch drain opening for standard bar and prep drain fittings.
• cUPC and IAPMO certified quartz sink meeting North American plumbing standards.

White That Works in a Bar or Prep Station

White is a strong choice for a secondary sink because it reads as intentional rather than utilitarian. In a white or light kitchen, this sink disappears cleanly into the design. In a darker kitchen or a contrasting stone counter, it anchors the bar area with a crisp accent. Either way, the matte white quartz surface keeps the look consistent whether the counter around it is light or dark. The square bowl shape reinforces that clean, architectural quality that suits both transitional and modern kitchens.

Quartz Composite Material and Finish

The Q-315 is made from quartz composite, a dense engineered material that combines the hardness of quartz with a uniform color that runs through the body of the sink. The white matte surface resists showing the minor scratches and water marks that would stand out on a glossy finish, making it a practical choice for a prep sink that sees frequent use. The bowl is 8 inches deep, which handles taller prep vessels without requiring a deeper cabinet cutout.

Where This Sink Works Best

This is a sink for a secondary station: a bar in an entertainment space, a prep bowl in a kitchen island, a compact vanity in a butler's pantry, or a small utility sink where a 21-inch-wide minimum cabinet is available. Because it is undermount only, it needs a countertop built to accept an undermount installation, such as laminate, solid surface, or granite. This is a sink to spec into a new countertop or a replacement counter, not a drop-in swap for an existing cutout. Designers specifying for a white kitchen will find the color coordinates cleanly with white cabinetry and most light stone or quartz countertop surfaces.
