The Outdoor Plus Gravity is a square, wood-burning smokeless fire pit aimed at buyers who want a more architectural alternative to a basic round fire bowl. The manufacturer currently lists the Gravity in 20-inch and 36-inch sizes and identifies the featured version as Corten steel.
What is the Gravity Smokeless Fire Pit?
The Gravity is part of The Outdoor Plus Smokeless Fire Pit lineup and is categorized by the manufacturer as a square outdoor fire feature. It burns wood rather than gas, so there is no gas-line or propane-cylinder decision involved in the standard Gravity configuration discussed here.
The defining visual feature is the geometric metal body. Corten weathering steel gives the fire pit an intentionally changing surface rather than a painted finish that is meant to stay visually identical year after year.
20-inch vs. 36-inch Gravity: which size makes more sense?
The manufacturer currently offers two nominal Gravity sizes, so the decision is less about choosing between different technologies and more about deciding how much visual scale you want the fire pit to carry.
| Choice | Best starting point for | What to verify |
|---|---|---|
| 20-inch Gravity | More compact contemporary layouts where the fire feature should complement the seating area instead of dominating it. | Confirm the current specification sheet and required clearances before finalizing furniture placement. |
| 36-inch Gravity | Larger patios where the square fire pit is intended to become a stronger architectural focal point. | Map the full product footprint into the project and leave room for manufacturer-required operating clearance. |
What should you expect from Corten steel?
Corten is weathering steel, so a changing exterior is part of the design. The surface develops a natural weathered appearance as the material is exposed outdoors. Buyers should expect variation rather than a perfectly uniform factory color.
This matters around light-colored stone, pavers and concrete. During weathering, runoff and surface residue can affect nearby finishes, so placement deserves the same attention as the fire pit itself.
The Outdoor Plus warranty documentation also makes an important distinction: fire pits carry a manufacturer warranty period, but natural weathering on Corten products is not itself warrantied. In other words, the evolving finish should be treated as part of the material rather than as a cosmetic defect.
Does “smokeless” mean the Gravity creates no smoke?
No. The Outdoor Plus classifies the Gravity as a Smokeless Fire Pit, but it is still a wood-burning appliance. A responsible expectation is reduced visible smoke under favorable burning conditions, not zero smoke in every situation.
Wood quality, moisture, startup conditions, wind and how the fire is managed all influence what you see above the pit. Dry, seasoned firewood is the sensible starting point for buyers trying to get the cleanest practical burn from a wood fire.

Who should buy the Gravity—and who should skip it?
- Choose Gravity if your patio uses straight lines, masonry, concrete or contemporary furniture and you want the fire feature to reinforce that geometry.
- Choose Gravity if you prefer the ritual and flame character of real wood instead of an instant gas flame.
- Choose Gravity if you like Corten precisely because its appearance changes outdoors.
- Skip it if instant on/off control and minimal ash cleanup are your top priorities; a gas fire feature will fit that ownership style better.
- Skip it if your local rules or current burn restrictions do not permit wood-burning fire pits.
What warranty applies to the Gravity?
The Outdoor Plus’s current warranty document lists a 1-year warranty for fire pits. Warranty coverage is for qualifying manufacturer defects and is subject to the manufacturer’s terms, exclusions and original-purchaser requirements. The same document states that natural weathering of Copper/Corten Steel products is not warrantied.
