- 1-1/2 yds. of sand
- 200 sq. ft. of flagstone(optional)
The easiest way to construct a stone fire pit is with stacked granite blocks (or other nonporous stone). Since the blocks are stacked on top of each other without mortar, they don't need footings and can be set directly on a bed of sand. Use wide, heavy blocks for stability. The cost for 24 granite blocks (enough to make a basic fire pit) is about $200. Just follow our easy step-by-step instructions...
- Mark a circular area in the yard big enough for the fire pit and, if desired, a flagstone patio surround. Cut out the sod and scrape out enough dirt so that your flagstones will come out level with the grass after being bedded in a layer of sand. Spread an inch of sand over the dirt and rake it smooth, leveling out the area where the fire pit will sit.
- Pound a spike in the center of the fire pit area, then loop a string around it to measure the inside circumference. Three to 4 feet is a good interior size for fire pits. Lay blocks out around the circle, then level. If the stones are tight against each other, leave small gaps for air vents. Move the stones as needed for even spacing.
- Add the second layer of stone, straddling the joints of the first layer. If a stone doesn't sit flat, add more sand under the skewed stone in the first course, then tap or wiggle it flat.
- After stones are set, add a few inches of sand or gravel inside the pit to raise the level of the fire so it's easier to tend. If building a surround, set flagstones outside of the fire pit, then fill in gaps with strips of sod.
