Bright White Finish And a Clean Undermount Fit

This Karran quartz double-bowl kitchen sink installs beneath quartz, granite, or solid surface countertops and delivers a crisp, all-white basin in an equal 50/50 split designed for everyday kitchen use.

Key Features

• Equal 50/50 double bowl configuration, with each basin mirroring the other for a balanced workflow.
• White quartz composite material built from natural quartz and acrylic resin for a dense, durable body.
• Undermount installation into quartz, granite, or solid surface countertops, requiring a 36-inch minimum cabinet width.
• 3-1/2 inch drain opening in each bowl for standard drain and disposal hardware.
• cUPC certified for compliance with North American plumbing standards.
• Pallet quantity of 20 sinks suited to builders, contractors, or cabinet shops outfitting multiple kitchens at once.

Equal Bowls for a Split Kitchen Workflow

Two identically sized basins let one side handle soaking or food prep while the other stays clear for rinsing or cleanup. Neither bowl dominates the layout, which works well for households and rental units where workflow habits vary. The undermount profile keeps the countertop surface unbroken at the rim, so wiping debris straight into either bowl takes no effort. Both basins share the same 9-inch depth, which gives enough room for pots and pans without turning the cabinet below into a plumbing obstacle.

A White Quartz Body Built for Hard Use

White is the sink finish most likely to read as part of the countertop in a light kitchen, and quartz composite supports that look with a consistent color that runs through the material rather than sitting only at the surface. The natural quartz and acrylic resin makeup produces a sink that holds up to the impact and thermal demands of a working kitchen. The 3-1/2 inch waste openings are the standard size for kitchen drain hardware, and the cUPC certification confirms the sink meets North American plumbing code requirements. Because this is an undermount-only design, it suits quartz, granite, and solid surface countertops; laminate or tile counters require a different mounting approach.

Who Reaches for This Sink

Cabinet shops, general contractors, and multifamily builders who need the same reliable white sink across multiple kitchens will find the pallet quantity practical. A white double-bowl sink also fits well in a single-family remodel where the countertop is light or neutral and the homeowner wants a clean, simple basin without a visible rim line. Designers specifying a bright, unfussy kitchen finish will find the 50/50 split more versatile than an offset or single-bowl configuration. The 36-inch minimum cabinet width is a standard base-cabinet spec for this sink class, so it slots into most kitchen plans without a custom build.
