18 Easy DIY Gas Fire Pit Ideas

Last updated on March 6, 2024

If you’re looking for a fun summer project, why not build a gas fire pit? These DIY tutorials will show you how to build one.

Building a gas fire pit is a relatively easy and affordable project that can be completed in a weekend. There are many different ways to build a gas fire pit, but most will require a manufactured fire pit kit, a propane tank, lava rock or fire glass, and a heat-tolerant material to cover the burner.

Important things to consider before making a gas fire pit:

A flat and fire-proof (non-combustible) surface to place it on.
Enough distance from the house (about 20 feet).
Clear area around the fire pit of about 6 feet.
Gas connection to the burner.
Spark ignition kit (preferably with a flame sensor.)
Proper ventilation.
Consider that you may need help from a professional.

These tutorials will provide step-by-step instructions on how to build your own gas fire pit, as well as tips on choosing the right materials and tools for the job.

With a little time and effort, you can have your very own DIY gas fire pit to enjoy for years to come.

Expected cost: $200

Materials:

Burner
Dante valve
Extended key
Reflective fire glass
1/2″ or 3/4″ gas fittings

These are all items that you will be hard-pressed to find at a local hardware store or Home Depot.

What you can find at a hardware store is all of the gas fittings you will need for the inside of your fire pit such as elbows, different lengths of pipe, etc. Every install is going to be a little bit different and whether you get 1/2” or 3/4” fittings will depend on what line you run to your fire pit.

We recommend running 3/4” up to the burner as it will give you a quieter fire pit.
