How to Illuminated Quartz Countertops

Illuminated quartz countertops can be a beautiful addition to any home. With their built-in LED lights, these countertops provide both form and function, adding style and lighting to kitchens and bathrooms. Installing illuminated quartz is relatively straightforward, but does require careful planning and some technical know-how. This comprehensive guide will walk you through everything you need to know to successfully install illuminated quartz countertops in your home.

Selecting the Right Illuminated Quartz

The first step is choosing the right quartz slab for your needs. There are a few key considerations when selecting illuminated quartz:


Thicker quartz materials tend to diffuse light better, resulting in a more even glow across the surface. Most illuminated quartz slabs are either 3/4″ or 1-1/4″ thick. The thicker quartz does cost more, but provides superior illumination.


Lighter quartz colors like whites and off-whites showcase illumination the best. Very dark colors can obscure lighting effects. Look for shades like vanilla, almond, and pearl that will allow internal LEDs to shine through.

Pixel Size

Illuminated quartz contains small LED diodes embedded in a grid pattern. The closer the pixels are spaced, the more uniform the lighting. Aim for 1-inch on-center spacing or less for optimal results.


Higher lumen LEDs emit brighter light. Look for quartz panels using at least 150-200 lumen diodes to ensure adequate brightness.

Once you select the right slab, it’s time to map out the installation.

Planning the Installation Layout

Taking careful measurements and planning the installation is crucial for a successful illuminated quartz project. Follow these steps:

Measure the Space

Record the precise dimensions of the countertop space. For seamless results, the quartz will need to be cut very accurately.

Make a Template

Some quartz fabricators can create a cardboard template directly from your measurements. This allows you to test fit in the space and identify any issues before cutting the real quartz.

Determine Seams

Minimize seams for the most seamless look. But take into account the size of the quartz slab. A single slab is usually about 55-65 inches long.

Map Electrical

Diagram all electrical components like outlets, switches, and lighting. This will guide the wiring plan.

Pick Edge Profile

Choose a low-profile finished edge to prevent LED hotspots. Pencil or thin bevel edges work best.

With careful planning and measurements, you’re ready to prep for installation day.

Preparing for Illuminated Quartz Installation

Proper preparation is a must for a smooth installation. Follow these tips before install day:

Clear the Space

Remove everything from the existing countertop. Have the base cabinets cleared out and ready.

Gather Supplies

Make sure you have all required materials and tools on hand before starting. See the installation supplies checklist below for details.

Turn Off Power

Shut off power to the kitchen/bathroom at the breaker before working with electrical.

Install Support Bracing

Quartz slabs require proper bracing every 18-24 inches along the underside.

Ready Electrical

Have wires ready to connect the LED lights to power. Follow local building codes.

With the prep work complete, it’s time for the fun part – installing the illuminated quartz!

Step-by-Step Illuminated Quartz Installation

Follow these key steps to properly install illuminated quartz:

Clean the Base Cabinets

Wipe down the countertop base to remove dust and debris before setting the quartz.

Set the Quartz Slab

Carefully lower the quartz onto the cabinet base. Have helpers to lift the heavy slab.

Make Connections

Attach LED wires according to the manufacturer’s instructions. Connect to power.

Apply Adhesive

Run a zig-zag bead of adhesive along the top of the base cabinets.

Set Quartz in Place

Carefully lower the quartz into place on top of the adhesive.

Clamp Edges

Use C-clamps along the edges to hold the quartz securely as the adhesive dries.

Clean Up Adhesive

Scrape away any excess adhesive squeeze-out with a putty knife once dry.

Caulk Seams

Apply a thin bead of clear silicone caulk along seams and edges if desired.

And that’s it – your new illuminated quartz countertops are installed! Admire the gorgeous glow.

Illuminated Quartz Installation Supplies

To make your install go smoothly, be sure you have these supplies on hand:

  • Quartz slab
  • Latex or polyurethane adhesive
  • C-clamps
  • Clear silicone caulk and caulk gun
  • Shims and adjustable braces
  • Putty knife
  • Shop vacuum
  • Electrical supplies like wire, wire stripper, wire nuts
  • Level
  • Safety gear – gloves, eye protection, etc.

Operating and Maintaining Illuminated Quartz

Once installed, follow these tips to keep your quartz counters looking beautiful:

Clean Regularly

Clean with a mild soap and water. Avoid abrasive cleaners that can dull the finish.

Repair Damage

Small chips and cracks can often be repaired with color-matched filler. Consult a pro.

Avoid Heat

Use trivets and hot pads. Illuminated quartz can be damaged by excessive heat.

Check Connections

Make sure wires are secure. Loose connections can interrupt lighting.

Replace LEDs

LEDs typically last 35,000-50,000 hours. Replace individual diodes as needed.

With proper care, your illuminated quartz countertops will provide stunning style and function for years to come! The glow adds ambiance and elegance wherever installed.

Frequently Asked Questions About Illuminated Quartz Countertops

How much does installed illuminated quartz cost?

Installed costs range from $80-$150 per square foot based on quartz quality. The LED lighting adds about $10-20 per square foot.

What thickness should I choose?

3/4″ quartz is standard, but 1-1/4″ provides the most uniform illumination. Go thicker if budget allows.

What lighting effects are possible with illuminated quartz?

Many systems offer adjustable brightness and colors like warm white, bright white, and colored LEDs. Some allow special effects like alternating colors.

Can the lights be controlled separately from the main kitchen lighting?

Yes, most illuminated quartz allows the LEDs to be controlled on a separate switch or dimmer for complete control.

How durable is illuminated quartz?

Quartz is very resilient. The polymer resins create an extremely strong surface that withstands wear, scratches, and heat. Illumination panels are designed to last for decades.

Can illuminated quartz get wet?

Absolutely. Quartz is non-porous and waterproof, making it ideal for kitchens and bathrooms. Just wipe up spills quickly to keep the surface pristine.

Is illuminated quartz eco-friendly?

Many quartz manufacturers use recycled materials in production. LEDs consume very little energy, so illumination has minimal environmental impact.


Installing illuminated quartz countertops creates a stunning focal point and sets your kitchen or bath design apart. While the installation process requires careful planning and precision, the remarkable results are well worth the effort. With proper selection of the quartz material, adequate preparation, and adherence to sound installation techniques, you can enjoy the beautiful glow of illuminated quartz counters that will last for many years.
