Karran Quartz & Stainless Steel Sinks Designed for Style & Performance

Seamless Even in Laminate

Thanks to Karran’s patented resin-matrix rim and two-part epoxy seal, our sinks are the only ones engineered for leak-proof undermount installation in laminate surfaces, making custom, high-end style accessible on budget-friendly counters

Outstanding Value & Finish Variety

Karran delivers premium materials and a broad palette, quartz finishes like Concrete, Bisque, Brown; brushed stainless steel that outperforms similarly featured competitors like Elkay or Blanco (who offer fewer finishes and higher prices).

Cleaner, Quieter Experience

Karran sinks include sound-dampening pads, tight-radius corners, and rear-drain designs. A features often missing in competing brands. These translate into quieter, more hygienic kitchen workflows and easier daily maintenance.

Can I use a Karran sink with a laminate countertop?

Yes. Karran sinks feature a unique resin-matrix rim designed for seamless undermount installation into laminate, solid surface, or stone countertops creating a clean, integrated look without rim overhang.

What does the Karran sink warranty cover?

Karran offers a Limited Lifetime Warranty for residential installations, covering defects in materials and workmanship for the original purchaser as long as the product remains in place.

What is the best way to clean and maintain my quartz sink?

For daily cleaning, use warm water and mild dish soap with a soft cloth or non-abrasive sponge. To enhance its shine, apply a small amount of Luster Pro conditioning oil about the size of a quarter wipe evenly, buff, and wipe off excess.

Can acrylic sinks be repaired if damaged?

Yes. Karran provides specific guidance and resources for repairing damage to acrylic sinks including an FAQ and instructional video to walk users through the process.

Where can I find installation guides and resources for Karran sinks?

You can easily access installation instructions, technical PDFs, and how-to guides plus resources for architects and fabricators on our product pages or contact our knowledgeable customer support for assistance. 

What are the actual bowl dimensions and cabinet size requirements for your sinks?

Understanding sink dimensions is key to fit and functionality. For example, the Karran QU‑812 32.5″ undermount quartz sink offers an inside bowl measuring 30″ x 16‑¾″ x 9″, and requires a minimum 36″ sink base cabinet for proper installation. It includes rear drain placement to maximize under-sink storage.

What are the sink clips for, and how do I install them?

Karran sinks come with specially designed mounting clips to ensure a secure, seamless fit during installation. These clips attach underneath the sink rim and clamp onto the countertop helping the sink sit flush and level while the silicone sealant cures. For best results:

• Place the paper template included in the box onto your countertop and mark the cut-out area.
• After cutting the countertop, apply a bead of silicone sealant around the rim area.
• Attach the mounting hardware to the rails under the sink rim, making sure the hooked side of the clip faces outward toward the countertop edge.
• Insert the sink, then tighten the clips in sequence—front first, then the sides and back—to ensure a snug, watertight fit.
• Let the sealant set for 30–60 minutes before use.
  If you encounter any issues or missing parts, Karran’s customer service is very responsive and ready to assist.
