How to Build a DIY Propane Fire Pit for Cozy Evenings

A propane fire pit is the perfect way to extend those cozy evenings outdoors. The warmth and ambiance of an open flame create a relaxing and inviting space for you to unwind alone or socialize with friends and family. Propane fire pits are also easier to use and maintain than traditional wood-burning pits.

Building your own DIY propane fire pit is a straightforward project that can usually be completed in one afternoon with minimal tools and materials. The end result is a beautiful and functional centerpiece for your patio, deck, or backyard. Follow this guide to construct your own propane fire pit tailored exactly to your space and needs.

Choosing a Location

When selecting where to build your DIY propane fire pit, there are a few key factors to consider:

Safety

Make sure to choose a spot at least 10 feet away from your home, trees, seating areas, or anything else flammable. Check local fire codes for any restrictions on open flames in residential areas. Avoid placing it directly under tree branches or roof overhangs.

Wind Exposure

Pick an area that is somewhat sheltered from strong winds, which can disrupt the flames. Partially enclosed spaces like courtyards are ideal.

Viewing Angles

Position the fire pit so that it can be easily viewed and enjoyed from seating areas or high-traffic zones. Face it towards views you want to highlight.

Surface Material

Select a flat, hard surface like concrete, stone, or gravel that can support the weight of the fire pit. Avoid grass, mulch, or dirt that can become fire hazards.

Utilities

You’ll need access to a gas line or propane tank to fuel the fire pit, so a nearby external wall is optimal. Ensure adequate drainage if you will use a water feature.

Privacy

Fire pits create light and sound that may disturb neighbors, so pick a private spot sheltered from adjacent properties by fences, foliage, or distance.

Once you’ve selected the perfect spot, it’s time to start planning out the fire pit design.

Designing Your Custom Fire Pit

One of the best aspects of DIY propane fire pits is that you can completely customize the design. Consider the following elements:

Shape

Fire pit shapes include circular, square, rectangular, oval, and freeform. Circular is most common and provides even flame distribution.

Size

Standard fire pits range from 3-5 feet in diameter but can be scaled up or down to suit your needs. Bigger sizes allow for larger groups.

Wall Height

Typically 6-12 inches high to balance safety and visibility. Shorter walls increase accessibility while taller walls boost ambiance.

Materials

Choose durable, non-combustible materials like concrete, stone, brick, stucco, metal, or gravel.

Features

Optional extras like benches, lighting, spark screens, glass beads, burners, accessories, and water elements. Get creative!

Sketch out some initial concepts, measure your space carefully, and finalize the design plan before starting to build. This will ensure the custom fire pit fits the location perfectly and has all the features you desire.

Gather Tools and Materials

One advantage of DIY propane fire pits is that they require minimal specialty tools and materials that are readily available. Here is a list of the basic supplies you will need:

Fire Pit Kit

Prefab square or circular propane fire pit burners and frames are available in various sizes at home improvement stores or online. These provide the foundation.

Exterior Building Materials

Such as concrete pavers or bricks to construct the fire pit walls around the burner. You’ll need enough to build to your desired height.

Crushed Stone/Gravel

One or more tons of pea gravel or crushed stone to fill in the center for drainage and stability.

Sand

Used to level and fill smaller gaps between wall materials.

Trowel, Shovel and Level

For grading, moving materials and checking for an even surface. A hand tamper can also be useful.

Drill and Masonry Bit

If using concrete or stone, a hammer drill is needed to make pilot holes for anchoring and gas lines.

Wrench

For securing gas line connections.

Outdoor Adhesive

Use an exterior-grade adhesive or concrete binder to attach wall materials.

Gas Line/Hose

Copper tubing or a flexible gas line to connect the propane tank or gas supply to the burner.

Propane Tank

A standard 20 lb. tank is sufficient for most DIY fire pits. You can opt for a larger tank if desired.

Fire Pit Cover

A fitted lid or heavy-duty tarp to protect the fire pit when not in use.

Aside from these basics, you may also want to accessorize your fire pit with lighting, spark screens, log sets, glass beads, or other embellishments. Make sure any additions are fire-safe.

Prepare the Installation Site

Once you have all your supplies in order, it’s time to start the exciting process of building your own propane fire pit. Follow these initial site preparation steps:

Mark the Fire Pit Location

Use stakes and string to outline the diameter of your fire pit. This will guide the construction.

Excavate Ground

Dig down 4-6 inches to create a recessed foundation for your fire pit materials to sit flush with the ground.

Install Gas Line

Run copper tubing from the propane tank to the center of the pit area if possible.

Fill Bottom Layer

Add a 2-3 inch deep layer of crushed stone/gravel and compact with the hand tamper.

Level Surface

Check for an even surface using a long level in multiple positions across the circle. Adjust gravel as needed.

With proper site preparation complete, you’re ready to start actually building up your custom fire pit walls to finish it off.

Build the Fire Pit Walls

There are lots of possibilities when it comes to constructing decorative and functional walls around your propane fire pit burner. Follow these tips:

Place the Burner

Position your fire pit burner frame centered neatly in the dugout space.

Dry Fit the Materials

Arrange the concrete pavers, bricks, stone or other materials without adhering them first.

Create the First Row

Apply adhesive to the gravel base and attach your bottom row of wall material in a circle.

Check Alignment

Verify the first row of bricks or other material is level and aligned properly before adding more.

Add Additional Rows

Lay each new row, staggering the seams and gluing into place. Let adhesive fully cure before the next row.

Leave Space for Gas Controls

As you build up the wall, don’t block burner controls. Leave gaps if needed.

Finish the Top Edge

The rim can be flat or you can angle the last row inwards slightly to finish it off.

Fill Interior Base

Pour crushed stone into the center open space to provide drainage under the burner.

Insert Burner

Place the prefab burner assembly on top of the gravel base in the center.

Take care to keep the fire pit walls as even and securely adhered as possible. Well-constructed walls not only look great but also safely contain the fire.

Install Gas Line and Burner

With the structure of your DIY propane fire pit complete, the final major task is installing the gas line and connecting it properly to the burner system.

Connect Tank to Shutoff Valve

Attach the propane tank to a shutoff valve using gas-rated fittings. This allows you to control fuel flow.

Run Line to Fire Pit Center

Lay flexible copper tubing or stainless steel gas line from the valve to the middle under the burner.

Attach Elbow Fitting

Use a 90-degree elbow fitting to route the gas line up vertically into the burner connection.

Secure Gas Line

Anchor the gas line in place at regular intervals so it doesn’t shift. Avoid kinks.

Apply Leak Detector

Spray leak detector solution on all connections and fittings to check for tight seals. Fix any leaks detected.

Test Burner Ignition

Once all connections are secure with no leaks, test lighting the propeller and make any flame adjustments.

Proper gas line installation provides safe, reliable fuel delivery to your propane fire pit burner. Always refer to the manufacturer instructions as well.

Finish the Fire Pit Surroundings

Put the final touches on your DIY propane fire pit with these optional finishes:

Fill Gaps

Apply sand between narrow wall material gaps for a flushed appearance.

Add Gravel/Stone

Spread pea gravel or crushed stone around the outer fire pit walls for a polished look.

Install Flat Stones or Pavers

Arrange stone or concrete pavers around the pit walls to create a patio surface.

Plant Landscaping

Surround the fire pit with gravel, plants, flowers, bushes or other landscaping.

Add Seating

Arrange chairs, benches, stools or log rounds around the perimeter of the fire pit.

Include a Spark Screen

Attach a mesh spark screen over part of the fire pit to prevent embers without obstructing flames.

Install Fire Pit Lid

Use a fitted heavy-duty cover to place over the fire pit when not in use.

Add Lighting

You can install low-voltage LEDs or tiki torches to illuminate the space at night.

Take time styling the area around your fire pit with plants, materials, seating and lighting to get the look and functionality just right. Now it’s time to start enjoying your new space!
