Materials

  • 48 cinder blocks (8 x 8 x 16 inches)
  • 12 cap blocks (2 x 8 x 16 inches)
  • 6 bags of gravel (50 lbs each)
  • 1 bag of lava rocks (40 lbs)
  • Shovel, level, and safety gloves

Instructions

  • Choose a level spot at least 10 feet from structures or trees. Mark a square area roughly 4 x 4 feet and dig 3–4 inches deep.
  • Fill the base with gravel for drainage and pack it down until firm.
  • Lay the first layer of cinder blocks in a perfect square. Then use a level to ensure all corners align.
  • Stack the next two layers, alternating the block direction slightly to leave air gaps—this helps the fire breathe.
  • Add a final layer of cap blocks on top for a polished edge and more heat containment.
  • Pour lava rocks inside the pit to protect the base and distribute heat evenly.
