Safety First
Before you start digging or laying bricks, choose a safe and practical location:

3. Tools and Materials You’ll Need
Tools
- Shovel or spade
- Measuring tape
- Level
- Tamper (or a flat object for compacting soil)
- Wheelbarrow (optional, for moving materials)
Materials
- Gravel or crushed stone (for the fire pit base)
- Sand (optional, for leveling)
- Fire-resistant bricks, pavers, or retaining wall blocks
- Fire ring insert (optional, for added durability and safety)
- Construction adhesive or heat-resistant mortar (optional for securing bricks)
4. Planning the Fire Pit Size and Shape
Standard Dimensions
- Diameter: 36–48 inches wide is a good size for a backyard fire pit.
- Height: Aim for about 12–18 inches tall for the walls.
- Depth: Dig 6–8 inches below ground level for a stable foundation.
Shape Options
- Round Fire Pit: The most common and easy-to-build shape.
- Square Fire Pit: A modern alternative that’s just as simple to construct.
5. Step-by-Step Instructions
Step 1: Mark the Fire Pit Area
- Use a measuring tape to determine the size of your fire pit.
- Mark the perimeter with spray paint, string, or a garden hose.
Step 2: Dig the Foundation
- Dig a circular or square hole within the marked area, about 6–8 inches deep.
- Remove all grass, roots, and debris from the area.
- Use a tamper or the flat side of your shovel to compact the soil, creating a stable base.
Step 3: Add the Base Layer
- Pour a 2–3-inch layer of gravel or crushed stone into the hole.
- Spread the gravel evenly and tamp it down to create a solid foundation.
- Optional: Add a thin layer of sand over the gravel for added leveling.
Step 4: Lay the First Layer of Bricks
- Arrange your bricks, pavers, or blocks around the edge of the foundation.
- For a round fire pit, slightly angle the bricks to follow the curve.
- Use a level to ensure the first layer is even and stable.
- Adjust the bricks as needed by adding or removing gravel underneath.
Step 5: Build Up the Walls
- Add additional layers of bricks, staggering the joints like a brick wall for added stability.
- If desired, apply construction adhesive or heat-resistant mortar between layers to secure them.
- Continue stacking until the walls are 12–18 inches high.
Step 6: Optional: Install a Fire Ring
- Place a metal fire ring insert inside the brick structure for added protection and durability.
- Ensure the fire ring fits snugly against the inner walls.
Step 7: Finishing Touches
- Fill the gaps between the fire pit and surrounding ground with gravel or sand to keep the area neat and prevent weeds.
- Clean the surface of the fire pit with a damp cloth to remove dust and debris.
- Add outdoor chairs or benches around the fire pit to create a cozy seating area.
