The Best Fire Pit Rings and Inserts
The cheapest real fire pit there is: a rolled steel band that lines a hole in the ground. Ranked on thickness and interior diameter, with the legal threshold marked.

A fire ring insert is a rolled steel band that lines a pit, above or in the ground. It holds the fire together and stops the walls collapsing inward. Expect 2 mm steel, 30 to 36 inches of interior, and a price a fraction of any manufactured pit the same size.

- Nothing to break. It is a rolled steel band
- Contains the fire and stops the pit walls collapsing inward, which is the actual job
- Costs a fraction of any manufactured pit of the same diameter
- No smoke reduction of any kind. This is an open fire
- Painted carbon steel will rust, so plan on replacing it eventually
- At 30 in of interior you are within inches of the 3 ft recreational-fire threshold
A yard with room to dig, and someone who wants an open wood fire and nothing else.
You have neighbors close enough to care about smoke, or you live where open burning needs a permit.

- A genuinely large fire for very little money
- The same simple construction as the 36 in
- 36 in of fuel area is at the recreational-fire limit, so read the rules page before you dig
- More fire means more clearance, and 25 ft from a structure is not negotiable in most codes
Acreage, a rural lot, or a property where the nearest structure is a long way off.
You are in a subdivision. This size is where permit questions start, and the answer is often no.

What a ring is actually for
Two jobs, and neither is the one people assume. First, it contains the fire: a defined edge means the fire stays where you put it and embers have a wall between them and the lawn. Second, and less obviously, it retains the pit. Dig a hole for a fire, burn in it for a season, and the sides erode and slump inward until you have a shallow dish. A steel liner stops that permanently.
What a ring does not do is reduce smoke, raise the fire off the ground, or provide any mechanism whatsoever. It is a band of steel, and that is the whole appeal: nothing to fail, and a very large fire for very little money.
Size is where this gets legal
The International Fire Code defines a recreational fire as one with a total fuel area of 3 feet or less in diameter and 2 feet or less in height. Below that, most jurisdictions permit it without a permit. Above it, you are conducting open burning, and open burning usually requires one.
| Ring | Outer | Interior | Against the 3 ft limit |
|---|---|---|---|
| Sunnydaze 36 in | 36 in | 30 in | Comfortably inside |
| Sunnydaze 42 in | 42 in | 36 in | Exactly at the line |
The interior is what holds the fuel, so the interior is the number that matters. A 42 in ring is a 36 in fire, which is 3 ft.
Being exactly at the line is not the same as being over it, and the 42 in ring is a legitimate purchase on acreage. It does mean that if a fire official ever measures it, there is no margin — and it means any variation in how you load it can push the fuel area past the definition. On a suburban lot, the 36 in ring is the sensible choice for reasons that have nothing to do with the fire and everything to do with the paperwork. What a recreational fire is.
Installing one
- 1Site it first, against the 25 ft clearance from any structure or combustible material that IFC 307.4.2 sets for a recreational fire. That is a 50 ft circle of open ground, and it rules out a lot of yards.
- 2Dig to the ring's height or a little less, so the rim sits at or slightly above grade. Buried too deep and the fire is starved of air.
- 3Line the base with sand or gravel, several inches, for drainage. A ring that fills with water rusts from the inside and turns to a pit of ash slurry.
- 4Set a border of non-combustible material — pavers, stone or gravel — a couple of feet wide around it. It keeps grass back from the heat and gives you somewhere to stand.
- 5Do not build a mortared surround unless you know what you are doing. Trapped moisture in wet concrete or fieldstone can flash to steam. Surfaces and pads.
Ring or bowl?
A ring gives you a much larger fire for much less money and commits you permanently to a spot in the ground. A bowl moves, needs no groundwork, and gives you a smaller fire. If you own the property, have the room, and want the biggest fire your rules allow, the ring is simply the better product — and it is the one that has been used for the purpose longest.
If you rent, or the yard is small, or the pit will need to move, an above-ground bowl is the answer instead. And if you are carrying it anywhere at all, a packable camp pit is a different tool again.
- Decorative cut-out fire rings as a primary pit
Star and moon cutouts look good and they let embers out at ground level. On a dry lawn that is the exact failure you are trying to prevent. Buy a solid ring and a spark screen.
- Anything over 36 in of interior in a subdivision
3 ft of fuel area is where a recreational fire stops being one under the code definition. Above it you are conducting open burning, which usually needs a permit. The definition.
- Ranked on published steel thickness first, then interior diameter against the 3 ft recreational-fire threshold.
- A metric thickness figure (2 mm) is more useful than a gauge number and both rings here publish one.
- What we did not do: install or burn either.
