A Clean White Double-Bowl Sink Built for Hard Countertops

This Karran quartz undermount sink delivers two equal bowls in a crisp white finish, designed to mount beneath granite, quartz, or solid surface countertops in kitchens requiring a 36-inch base cabinet or wider.

Key Features

• Equal 50/50 double bowl configuration with matching 14-1/4 inch bowl length and 9-inch depth on each side.
• Quartz composite construction for a dense, hard body with a consistent white color throughout.
• Undermount installation into granite, quartz, or solid surface countertops only.
• cUPC and IAPMO certified for code compliance in residential kitchen installations.
• Minimum 36-inch base cabinet required for proper fit.
• 3-1/2 inch drain openings sized for standard kitchen waste fittings.

Two Bowls That Keep Kitchen Tasks Separate

A 50/50 split means both sides carry the same footprint and depth, so neither bowl is an afterthought. One side can hold a soaking pot while the other stays clear for rinsing produce or prepping ingredients. The equal configuration also makes it straightforward to swap tasks between sides without one bowl always being too shallow or narrow for the job at hand. Both bowls sit at 9 inches deep, which is enough depth to submerge a large stockpot or a sheet pan for soaking without water spilling over the rim.

White Quartz That Reads as Part of the Counter

White is the finish that disappears into light-colored countertops and cabinetry, letting the rest of the kitchen lead visually. This sink is made from quartz composite, a dense engineered material with the look and weight of natural stone and a color that runs through the body rather than sitting as a surface coating. The result is a finish that holds up to daily use without looking worn at the edges or showing chips the way a glazed or coated surface might. Against a white or light quartz countertop the sink transitions cleanly, with no visible rim above the surface to interrupt the counter line.

Where This Sink Fits Best

This sink is the right choice for a kitchen remodel or new build where the countertop is being fabricated from granite, quartz, or solid surface material and the aesthetic calls for a clean, bright white basin. Because it is undermount-only, it requires a countertop that supports undermounting, and it is designed for new countertop installations rather than drop-in replacement of an existing cutout. Designers specifying a white-on-white or white-and-stone kitchen will find the quartz body and the flush undermount install work together cleanly. Cabinet shops planning the rough opening should allow for the 36-inch minimum cabinet width and verify the 32-3/8 by 19-1/4 inch overall footprint fits the planned layout before the counter goes in.
