Gas fire pits come with a lot of advantages that make them a no-brainer choice over any traditional barbecue grill. It’s true that they require some work at first and need to be built into your backyard, but that shouldn’t be a problem since after you read this article, you’ll be able to make one yourself in your backyard as a DIY activity.

Of course, there are a lot of things to cover with this project and everything needs to be done the right way, which is why we dedicate this article solely to make sure every house is able to make their own gas fire pit with the least number of tools possible.

Enough talk and let’s get right into it with this new DIY project!


Before we get down to the actual procedure, we need to make sure a few things are set straight. One of the most important factors of making this gas fire pit is the location, as it can either be very helpful or very troubling throughout the process.

You’re going to pick a place in your backyard that is perfect for the kind of usage you’re going after. You can either set it on an existing patio, or just on the ground, either way the area in which you set it shouldn’t be obstructing movement and shouldn’t be in the very middle of the backyard.

Somewhere near the corner or the wall is a good place.

Things to Consider

How to Build a Gas Fire Pit

Now before we start building the gas fire pit, there are a few things you should be aware of.

Let’s talk about them!

First, the gas fire pit’s design features are just as important as the location.

The size of your fire pit should be big enough for barbecuing a good amount of food, but shouldn’t be too big that you wouldn’t be using all that space.

You can make your fire pit any shape you want, but you have to know that each shape has its own ups and downs. For me, I’d make it round for easy access from all sides.

You should also think about the materials that you’ll use to make it. The materials should be strong enough not to be eaten by the constant fire, and also shouldn’t be emitting toxic gases when in contact with it.

Let’s check out the tools you’ll need to make your gas fire pit.


  • Concrete Hardscape Block
  • DIY Gas Burner Kit with Control Panel
  • Lava Rock Or Other Filler Rated for Use with Gas Fire Pits (.5 Cubic Bag or Approximately 20 Lbs Recommended)
  • 1 Vent Block (Optional)
  • Exterior-Grade Concrete Adhesive
  • One AAA Battery For Burner Ignition
  • Vapor Barrier (If Building in Grass or On Pavers)
  • Level
  • Shovel (If Building in Grass)
  • Rake (If Building in Grass)
  • Mallet
  • Caulk Gun
  • 2 Adjustable Wrenches
  • 7/16” Wrench
  • Power Drill with Phillips Bit


Now that we’ve gotten everything out of the way, it’s time to actually start building the gas fire pit, follow along for a step by step guide into how you can do it yourself!

The only thing you can’t do yourself in this DIY project is actually the first step.

Step #1:

Have a certified technician install a natural gas line to the place where you’re going to build the fire pit.

Step #2:

Clear a 40” diameter circle from grass, roots, and anything that can obstruct the building of the fire pit. After that, dig out 2 inches of soil from the same circle, and fill it back up again until it is leveled. Add up to 2 inches of paver base.

Step #3:

Now it’s time to install the vapor barrier. After that, lay a ring of hardscape blocks in a circle, just make sure the interior diameter is anything more than 32 inches.

For the hardscape block, you should use 4-inch tall tumbled radius pavers.

Step #4

While keeping enough space for a control panel vent block, place the second ring of concrete block.

Step #5

Now it’s time to make everything stick together. To do that, slowly remove 1 block at a time and apply concrete adhesive. Put the blocks back where they were and apply some pressure to make sure they are stuck together.

Step #6

Now it’s time to assemble the burner you’ve got and carefully place it on top of the concrete block ring. Make sure the burner has at least 1-inch overlap over the ring so that it is secure.

Of course, you’re going to need to use the burner’s manual to make sure you’ve got everything right when assembling it.

Step #7

Now you should add a third layer of concrete block, this time over the burner you just installed. Follow the same previous steps and apply the adhesive to make sure everything is secure together.

After this step, all you have to do is light up your fire and gather everyone around for a nice barbecue.
