Building a DIY Fire Pit (Step-by-Step)

Step 1: Mark the DIY Fire Pit Area

Start by defining the layout of your fire pit space.

Placed a stake in the center of the desired area
Attached a rope and used it as a guide
Spray-painted a perfect circle on the lawn

We chose:

~14 ft diameter for the full seating area

This step helps visualize the final space and keeps everything symmetrical.

Step 2: Build a Concrete Border

To contain the gravel and define the space:

Cut MDF panels into thin strips using a table saw
Formed a circular mold along the spray-painted line
Secured the mold using stakes

Then:

Mixed and poured concrete into the mold
Worked section by section for better control

This created a clean, durable border that holds everything in place.

Tip: Keep the mold level to ensure an even, professional-looking edge.

Step 3: Level the Ground & Prep the Base

Before installing the DIY fire pit:

Marked the exact center of the circle
Added a layer of sand to level the ground
Smoothed everything out using a level

A solid, level base is key for both safety and appearance.

Step 4: Build the DIY Fire Pit Structure

For the main fire pit:

Used a 30” fire bowl as the core
Placed it at the center

Then built around it using:

Limestone retaining wall blocks

Details:

Approx. 33 blocks total
Stacked in 3 rows around the bowl

This creates a permanent, clean look while still keeping the fire contained safely.

Tip: You can often find fire bowls secondhand to save even more money.

Step 5: Fill the Area with Gravel

To complete the space:

Filled the entire circle with limestone gravel
Used about 1 cubic yard total

Why gravel?

Budget-friendly
Provides drainage
Adds texture and contrast

To save money:

Rented a flatbed truck
Picked up gravel from a local supplier instead of buying bags

This made a big difference in overall cost.

What I learned (important!):
Originally, we installed landscaping fabric underneath the gravel to prevent weeds and grass growth. While it helped initially, over time weeds and grass still pushed through—and it turned into constant maintenance.

So I changed the approach and added a thin layer of concrete underneath the gravel. This made a huge difference: No more weeds or grass growing through and almost zero maintenance now!

At first, I was concerned about drainage, especially during heavy rain. But even with torrential downpours, we’ve never had standing water—so it turned out to be a great long-term solution.

Step 6: Add Seating & Style the Space

To turn the DIY fire pit into a true hangout area:

Placed Adirondack chairs around the pit
Added hammocks nearby for extra lounging space

Now the area works with a fire or just as a casual seating zone.

This fire pit completely changed how we use our backyard.

Now we have:

A dedicated entertaining space
A cozy place to relax year-round
A visually appealing backyard feature

Even when it’s not in use, it adds structure and character to the yard.
