Installing Brick Grill Island on your Backard

Building a brick grill island in your backyard is a great way to create a unique outdoor cooking space. This project is not for the faint of heart, but if you’re up for the challenge, it’s definitely worth it! 

In this guide, we will show you how to install a brick grill island in your backyard. This project requires some basic masonry skills and tools. The most important thing is to take your time and

follow the instructions carefully. With a little effort, you will be able to create a beautiful and functional outdoor cooking area that will be the envy of your neighborhood.

How to Build a Brick Grill Island

In order to build a brick grill island, you will need the following tools and materials:

  • Trowel
  • Chisel
  • Hammer
  • Mortarboard
  • Mortar Mix
  • Shovel
  • Bricks
  • Weber or Another Charcoal Grill

Making The Base

After you’ve selected the perfect location for your backyard paradise, it’s time to start building! The first step is to create a level surface for your brick grill island. You can do this by excavating the area to a depth of about 6 inches and then adding a layer of gravel. Next, you’ll need to install some form boards around the perimeter of the excavation. These will act as a mold for the concrete base of your grill island. Once the form boards are in place, you can mix and pour the concrete. Be sure to smooth it out so that it will be even when dry.

Adding The Bricks

Once you have your grill island frame in place, it’s time to start adding the bricks. The type of brick you use is up to you, but we recommend using a fire brick or a refractory brick. You’ll need about two hundred bricks for this project. If you’re using a refractory mortar, mix it according to the instructions on the package. If you’re using a regular masonry mortar, mix it with one part Portland cement and four parts sand.

To start, apply a layer of mortar to the first course of bricks with a trowel. Then set the bricks in place, tapping them gently with a rubber mallet to seat them evenly in the mortar. Repeat this process until the entire first course is complete. Use a level to check that the first course is level before moving on to the second course.

Continue adding courses of bricks, checking for level as you go. When you reach the desired height for your grill island, stop adding courses and allow the mortar to cure for at least 24 hours before using your new grill island.

Finishing Up

The final touches for your brick grill island are adding the shelves and side tables. Start by building the shelves for the side table using 2x4s and 3/4″ plywood. Cut the plywood to size and then attach it to the 2×4 frame using construction adhesive and 1-1/4″ screws. Repeat this process to build the other shelf. Once the shelves are built, you can attach them to the side of the brick grill island using construction adhesive and bricks.

To finish up, add the side tables to your brick grill island. Cut two pieces of 2×4 lumber to size and then attach them to the top of the brick grill island using construction adhesive and 1-1/4″ screws. Cut two sheets of 3/4″ plywood to size and then attach them to the 2×4 frame using construction adhesive and 1-1/4″ screws. Once the side tables are built, you can finish them off by attaching a piece of trim around the edge of each table top.

Tips and Tricks

Before you purchase your supplies or begin installation, it’s important to take some time to plan the design of your grill island. You’ll need to consider the size and shape of your backyard, as well as any existing features or structures that could impact the placement of your grill island.

Once you’ve determined the perfect spot for your grill island, you can begin gathering the supplies you’ll need for the project. In addition to bricks, mortar, and grilling equipment, you may also need:

  • A level 
  • A tape measure
  • Shovels 
  • Wheelbarrows 
  • Trowels 
  • A level line 
  • A straight edge 
  • Brick laying tools

With all of your supplies on hand, you’re finally ready to begin installation. The first step is to create a level base for your grill island. This can be accomplished by excavating a small area of grass or soil and leveling it with a shovel. If you’re working with an existing concrete patio or deck, you may be able to skip this step.

Once your base is level, you can begin laying bricks. Start at one corner of the base and work your way around in a spiral pattern. When setting each brick, be sure to use mortar in between joints to ensure stability. You may also want to use a level or straight edge to check each row as you go, keeping things even as you work.

As you near the top of your grill island, it’s time to start thinking about ventilation. To ensure proper airflow while cooking, be sure to leave space for at least one hole near the top of the structure. This will serve as an outlet for smoke and heat while also allowing you to add fuel without opening the entire structure.

Finally, once all bricks are in place and mortar has had adequate time to set, it’s time to add grilling equipment. Mounting brackets can be attached directly to brick surfaces using masonry screws designed for the task. Then simply add your favorite grill, smoker box, or side burner and get ready for hours of outdoor cooking enjoyment!


Building a brick grill island in your backyard is a great way to entertain guests and enjoy outdoor cooking. Follow these instructions to ensure that your project is successful.

First, determine the size and shape of your island. Next, prepare the area where the island will be built by leveling the ground and excavating any sod.

Next, lay a bed of gravel to serve as a foundation for the island. Then, begin building the walls of the grill island by stacking bricks on top of one another. Be sure to use mortar between each brick to create a strong bond.

As you build up the walls, create openings for vents and doors. Once the walls are complete, finish the project by installing a metal grill or cooking surface on top of the island. Add countertops around the perimeter of the island for food prep and serving space.

Enjoy your new backyard entertaining space!
