It’s not that hard to build a basic outdoor fire pit. You can do it in an afternoon, with a little elbow grease and less than $100.
TOOLS
- shovel
- level
MATERIALS
- retaining wall blocks (we used about 36)
- metal fire pit ring
- 7” square concrete pavers or fire brick for the bottom of the pit (we used about 15)
STEP 1
Plan Location and Layout
A fire pit should be built at least 15 feet from any structure and close to a water source. Ideally, you’ll want it on level ground; it’ll make building it much easier and sitting around it more comfortable.
STEP 2
Determine the Size
The size of your fire pit will be determined by your metal fire ring. Place the ring and retaining-wall blocks on the ground to figure out the size of the fire pit. Mark the outside of the circle with the edge of a shovel.
STEP 3
Dig a Hole
Move the retaining wall blocks out of the way and dig inside the marked hole. Make the hole at least 7” deep.
STEP 4
Line Hole With Sand
Add a 1” layer of all-purpose sand in the hole and tamp it down flat. You may want to use a level to make sure it's all on the same plain.
STEP 5
Add Base Row
Lay the bottom row of blocks inside the hole. Place the outside of the block on the very edge of the sand.
STEP 6
Place Metal Ring
Place the metal ring on the sand inside the base row of blocks.
STEP 7
Insert Bricks Into Fire Pit Floor
Lay the pavers or fireplace bricks in the bottom of the fire pit. Cover as much area as possible.
STEP 8
Add Pea Gravel
Fill the gaps between the blocks and the pavers with pea gravel.
STEP 9
Place Remaining Rows of Blocks
Stack the outer blocks to your desired height. Stagger the seams of each layer.
