Karran Quartz Undermount Sink for a Clean White Kitchen

This Karran single-bowl undermount sink brings a crisp white finish to kitchens built around quartz, granite, or solid surface countertops. The quartz composite body pairs with an undermount installation that keeps the counter surface unbroken from edge to bowl.

Key Features

• Single bowl configuration with a 29-inch interior length and 9-inch depth for generous, uninterrupted capacity.
• Quartz composite material offering a dense, consistent body in a bright white finish.
• Undermount installation into granite, quartz, or solid surface countertops, requiring a minimum 36-inch cabinet width.
• 3-1/2-inch drain opening sized to accept standard strainer and disposal flange hardware.
• cUPC and IAPMO certified to meet North American plumbing standards.

One Deep Bowl, No Divider in the Way

A single-bowl sink suits kitchens where large items move through the basin regularly — sheet pans, stock pots, cutting boards heading into the rinse cycle. Without a divider taking up interior width, the full 29-inch bowl length stays open for oversized cookware. The 9-inch interior depth adds working room without requiring you to reach over a high rim. White makes the interior easy to read at a glance, so debris and residue are visible rather than hidden by a dark surface.

Quartz Composite Built for the Counter

The sink is constructed from quartz composite, a dense material that holds its color consistently through the body rather than relying on a surface coating. The white finish reads clean and bright under kitchen lighting and coordinates naturally with white cabinetry, marble-look countertops, and painted or white-glazed tile. Because this is an undermount, the countertop edge finishes flush to the bowl wall with no rim on top, which simplifies wiping down the counter and keeps the installation looking intentional rather than utilitarian.

Where This Sink Fits Best

This sink works well in a primary kitchen where a single large basin handles everything from prep to cleanup, or in a kitchen renovation where the countertop is being fabricated new. It is sized for a 36-inch base cabinet, which is a common kitchen sink cabinet width, and mounts into granite, quartz, or solid surface countertops. It is designed for new countertop installations rather than retrofitting into an existing cutout. The cUPC and IAPMO certifications satisfy code requirements across most North American jurisdictions, which matters for permitted remodels and new construction alike.
