Undermount Sinks

A Karran undermount sink is a quartz composite and stainless steel sink that installs beneath the countertop surface, creating a seamless transition between the sink and counter. Karran is best known for pioneering the only undermount sink system designed to work with laminate countertops — something traditional undermount sinks can't do.

Yes — but only with the right system. Karran developed a patented undermount system specifically engineered for laminate counters, making them the leading choice for homeowners who want the seamless look of an undermount sink without switching to stone or solid surface countertops.

Quartz composite is an engineered material made from approximately 80% crushed natural quartz combined with acrylic resin. The result is an extremely durable, non-porous surface that resists scratches, stains, impacts, and heat. It absorbs sound better than metal sinks.

Karran's stainless-steel models use T304 stainless steel with an 18/10 chromium-nickel composition, which helps resist rust, staining, and corrosion over time.

Significantly quieter than stainless steel. The dense composite material absorbs sound from dishes, silverware, and running water, making the kitchen feel calmer during use. It's one of the most-noticed differences customers report after switching from stainless.

Routine cleaning is simple — soap, water, and a soft sponge. The non-porous surface resists bacteria and staining, so no special products or sealing are needed. For tougher buildup, a mild non-abrasive cleaner works well. Avoid harsh abrasives or bleach-based cleaners on a regular basis.

Karran undermount sinks typically cost more than basic stainless steel options, but less than premium fireclay or copper sinks. Pricing varies by model, size, and features (workstation accessories, color, configuration). Request a free quote and we'll provide accurate pricing for your project.

Karran undermount sinks are compatible with virtually every countertop material — laminate (their signature offering), quartz, granite, marble, acrylic solid surface, and concrete. The undermount installation is coordinated with the countertop fabrication for a precise, watertight fit.
