Warm Brown Tone, Deep Single Bowl, and a Farmhouse Profile Built to Last

The Karran QA-740-BR is a single-bowl apron-front farmhouse sink in quartz composite, finished in brown, that mounts beneath granite, quartz, or solid surface countertops. Its exposed apron front and generous bowl depth make it a natural anchor for kitchens where the sink is meant to be part of the design, not hidden behind cabinetry.

Key Features

• Apron-front farmhouse profile with the front panel sitting proud of the cabinet face for a classic farmhouse presence.
• Single bowl at 31 inches long and 9 inches deep, sized for large pots, sheet pans, and high-volume cleanup.
• Brown quartz composite body that integrates naturally with wood tones, warm stone, and earthy kitchen palettes.
• Undermount installation into granite, quartz, or solid surface countertops, keeping the counter surface flush to the bowl edge.
• Requires a minimum 36-inch base cabinet for proper fit and support.
• cUPC and IAPMO certified for plumbing code compliance across North American markets.

One Deep Bowl for the Full Range of Kitchen Work

A single-bowl farmhouse sink removes the center divider that limits how tall or wide a pot, tray, or cutting board can be, so this one handles the jobs a divided sink cannot: soaking a full sheet pan, washing a large stock pot upright, or bathing a deep roasting pan without tipping it sideways. The 9-inch bowl depth adds clearance for bulky loads without splashing, and at 31 inches across the interior, there is room to work rather than maneuver. This is a working kitchen sink built for volume, not just for appearance.

A Brown Quartz Finish That Earns Its Place in the Design

Quartz composite construction gives this sink a dense, stone-like feel and a surface that does not flex under load or ring when a pan drops in. The brown finish is a considered choice for kitchens built around warm wood cabinetry, terracotta tile, natural stone counters, or earth-toned palettes where a white or gray sink would read as a contrast rather than a complement. The apron front stays visible at the cabinet face, so the color registers as a design element, not just a utility fixture. Because the apron is exposed rather than hidden, the brown reads across the room and works with surrounding materials the way an undermount sink hidden behind cabinetry simply cannot.

Where This Sink Fits Best

Plan this sink into a new build or a remodel where the countertop is being fabricated from scratch. It is an undermount sink and requires a granite, quartz, or solid surface countertop for proper support. It does not drop into an existing countertop cutout, and it is not compatible with laminate or tile. The sink needs a 36-inch or wider base cabinet, and the apron-front profile requires a base cabinet configured to accept a farmhouse sink. Designers specifying for a rustic, transitional, or warm-contemporary kitchen will find the brown finish fills the color gap between a stark white and a cool gray without leaning heavily dark. Cabinet shops building a farmhouse-sink base should confirm the cabinet rough opening against the 34 by 21-1/4 inch footprint before cutting.
