Spring is around the corner, and if your feed looks anything like mine, everyone is talking about outdoor living spaces. Fire pits are trending hard right now — and for good reason. They are one of the highest-impact, lowest-cost backyard upgrades you can do yourself.
Here is how to knock one out this weekend.
What You Need
- 36 retaining wall blocks (roughly $2-4 each at any hardware store)
- Gravel — one bag of pea gravel, one bag of crushed stone
- A shovel and a level
- Optional: fire-rated adhesive, steel fire ring insert
Total cost: $75–$150 depending on your area. Compare that to $800+ for a contractor.
The Build (3-4 Hours)
Step 1: Pick Your Spot
At least 10 feet from any structure, fence, or overhanging branches. Check local fire codes — most cities have specific setback requirements. Not sure about your area? Snap a photo of your yard and ask an AI assistant for guidance (more on that below).
Step 2: Dig the Base
Mark a circle about 36-44 inches in diameter. Dig down 6 inches. Keep it level — this matters more than you think. A wobbly fire pit looks amateur.
Step 3: Lay the Foundation
Pour 3 inches of crushed stone. Tamp it down. Add 1 inch of pea gravel on top. Level again.
Step 4: Stack the Blocks
First ring goes right on the gravel. Use a level as you go. Most people do 2-3 rings high. Stagger the joints like brickwork. Optional: use fire-rated adhesive between layers for permanence.
Step 5: Fill and Finish
Fill the interior base with a couple inches of pea gravel for drainage. If you bought a steel ring insert, drop it in now. Backfill around the outside with dirt or decorative stone.
That is it. Light a fire tonight.
Common Mistakes to Avoid
- Using regular concrete blocks — they can crack or even explode from heat. Use retaining wall blocks or dedicated fire pit blocks.
- Skipping the gravel base — water pools underneath, blocks shift, you rebuild next year.
- Building on grass — the grass underneath will die and create a mud pit. Always dig down to bare soil.
- Ignoring drainage — if your yard slopes, water will pool in the pit. Grade the base slightly or add extra gravel.
When to Call for Help
Not every project should be DIY. If you are dealing with gas line hookups, retaining walls on slopes, or are unsure about local building codes, get a professional opinion first.
Not sure whether your project is a DIY job or a pro job? Fixy can help you figure that out.

It is like having a contractor friend in your pocket — minus the $150 consultation fee.
Wrapping Up
A fire pit is one of those rare projects where the effort-to-reward ratio is absurdly good. A few hours of work, under $150 in materials, and you have a backyard gathering spot that will get used all year.
