Even with these restrictions, our family still loves to sit around an evening fire. But we didn’t want to spend a small fortune on a pre-manufactured fire pit or a contractor built unit. We were also not sure where we might permanently want the pit located. So we needed something we could take down and move to a different spot without a lot of trouble or expense..
Fortunately, while cruising the isles of Home Depot recently, we saw concrete tree rings on sale for $2 a section. We borrowed a tape measure and quickly determined the rings might make a dandy low cost fire pit that would incorporate a small Weber grill (which we already owned) as an inner firepot, allowing a very controlled burn and positive air shut off to extinguish the fire when we were ready to call it a night.
Weber Smokey Joe Portable charcoal grill or equivalent 14" diameter grill. ($30 new)
4 sections of 14" inside diameter concrete tree ring ($2 to $3 each = $8 to $12 total)
6 sections of 24" inside diameter concrete tree ring ($2 to $3 each = $12 to $18 total)
2 cubic feet of small stones, pebbles, road gravel or decorative rock ($0 to $20 depending on how fancy)
Total cost $50 to $80 depending on your taste in stones.
