Materials
- 36 retaining wall blocks (4 x 12 x 8 inches)
- 1 steel fire ring insert (30 inches diameter)
- 1 round grill grate (adjustable or 24 inches diameter)
- 6 bags of gravel (40 lbs each)
- Shovel, level, and tape measure
Instructions
- Mark a circle about 40 inches wide in your desired area. Remove grass and dig 3–4 inches deep for a stable base.
- Pour in gravel to create a level and fire-safe foundation, tamping it down firmly.
- Arrange the first layer of retaining wall blocks in a circle, fitting them snugly together. Then add two more layers, staggering the seams for strength.
- Place the steel fire ring inside the block circle for added safety and durability.
- Set the grill grate on top or slightly inside the ring. You can adjust for height or add removable sticks as simple skewer rests.
Notes
Choose heat-resistant blocks and a coated steel ring to prevent cracking. You can easily remove the grate when not grilling, transforming the pit into a traditional fire feature for gatherings.
