How to Wall Mount Quartz Countertops

Wall mounting quartz countertops can create a beautiful, modern look for your kitchen or bathroom. Quartz is an engineered stone that is very strong and durable, making it a great choice for wall mounted installations. With proper planning and preparation, you can successfully install wall mounted quartz yourself.


Quartz countertops have become increasingly popular in recent years due to their stylish appearance and extreme durability. Made from ground quartz crystals combined with resins and pigments, quartz is non-porous, stain and scratch resistant, and can withstand high temperatures.

Wall mounting quartz countertops can help create the illusion of a larger space, while also allowing for easier cleaning underneath. It provides a streamlined, minimalist aesthetic. With the right tools and techniques, quartz can be mounted securely and safely on the wall as a single slab or in multiple pieces.

Before beginning the installation, it’s important to choose the right type of quartz and purchase the necessary brackets and supplies. Properly measuring and preparing the wall surface is also crucial for a successful end result. With patience and care, you can have stunning wall mounted quartz countertops that will last for many years.

Considerations Before Installing Wall Mounted Quartz

There are several important factors to consider before installing wall mounted quartz countertops:

Selecting the Quartz

  • Choose an engineered quartz product specifically designed for wall installations. Some quartz formulations are too soft or flexible for mounting. Consult with quartz manufacturers to ensure the product can be mounted.
  • Select a color, finish and thickness you find visually appealing. Thicker quartz (2cm or 3cm) is best for wall mounting.
  • Measure the dimensions of your wall space carefully to determine exactly how much quartz you need to purchase.

Structural Integrity

  • The wall must be structurally sound to support the weight of the quartz. Wall mounted slabs can weigh over 100 pounds.
  • Steel stud walls may require additional reinforcement to properly bear the load. Consult an engineer or contractor if unsure.
  • Wall anchor bolts must be securely fastened to adequately support the quartz weight. Choose high quality, heavy duty brackets and fasteners.

Moisture Protection

  • Properly seal the wall and protect underlying materials from moisture damage.
  • Any plumbing or electrical lines on the wall must be relocated before installing quartz.

Safety Concerns

  • Overhead installations should be out of the reach of small children to prevent injury.
  • Properly cured adhesives and mechanical fasteners are vital to prevent quartz from detaching and falling.

Aesthetic Layout

  • Decide if you want a single slab or multiple pieces for visual interest.
  • Measure and map out exact quartz dimensions and positioning.

How to Install Wall Mounted Quartz Countertops

With careful prep and the right techniques, you can achieve stunning results:

Prep the Wall

  • Remove existing countertop or wall materials as needed to expose the bare wall.
  • Inspect wall structure and reinforce if necessary per engineer recommendations.
  • Seal the wall with a waterproof membrane for moisture protection.
  • Mark precise stud locations for proper bracket placement.

Cut and Polish the Quartz

  • Have quartz slab factory cut to your specifications if possible.
  • Cut and polish edges using a wet saw with diamond blade.
  • Sand and buff all cut edges completely smooth.

Mount the Brackets

  • Choose high quality brackets designed specifically for quartz.
  • Attach brackets securely to wall studs using lag bolts.
  • Ensure top of brackets align to proper quartz height and position.

Adhere the Quartz

  • Clean back of quartz and wall surface thoroughly.
  • Apply adhesive (construction glue or silicone) evenly.
  • Carefully mount quartz onto brackets, pressing firmly for strong adhesion.
  • Allow adhesive to fully cure per manufacturer instructions (usually 24-48 hours).

Finish the Installation

  • Apply color-matched caulk around all edges for a seamless look.
  • Clean and polish the quartz surface once mounted.
  • Seal any cracks or crevices between wall and quartz.

FAQs about Wall Mounted Quartz

Is wall mounted quartz safe and secure?

Yes, with proper installation using the correct adhesives, brackets, and support, wall mounted quartz is extremely secure and safe. Good preparation is key.

How much weight can my wall support?

Most standard interior walls can support 50-100 lbs per square foot. A 2 cm thick quartz slab equates to about 7 lbs per square foot. Ensure your wall meets structural requirements.

What’s the best adhesive for quartz?

Silicone or construction adhesives specifically designed for stone work best. Avoid standard glues which can discolor and fail over time.

Can quartz crack when mounted to a wall?

It’s unlikely, but poor installation or inadequate wall support could lead to cracks. Take precautions to reinforce the wall and use the proper brackets.

Do I need special tools for cutting and drilling quartz?

Yes, you need a diamond-tipped blade wet saw for cuts. Use a diamond-tipped masonry drill bit for any necessary holes. Never cut quartz dry.

How far apart should I space the mounting brackets?

As a general rule of thumb, brackets should be spaced every 16 to 24 inches. Follow manufacturer recommendations for exact specifications.


With the right planning, prep work, materials, and technique, installing stunning wall mounted quartz countertops is an achievable DIY project. Carefully reinforcing the wall, selecting quality quartz, utilizing heavy duty brackets, and proper adhesion will result in safely secured, beautiful quartz that will last for decades. Take the time to properly measure, mount the brackets, and securely adhere the quartz. Wall mounted quartz is a gorgeous focal point that can completely transform a room.
