Octagon Fire Pit Form, 16 inches tall: a low eight-sided shell for your own finish
The Outdoor Plus Octagon Fire Pit Form is a raw hardie board shell, ready for stone or tile. Its eight flat sides give clean corners. Choose 36, 48, 60, 72, or 84 inches. At 16 inches tall, it keeps flames visible from outdoor sofas.
Order it for natural gas or propane. Light it with a match, or add electronic ignition and start it with a button. The stainless pan, burner, key valve, hoses, and air vent are inside; a bullet burner upgrade, fire glass, and burner ornaments are optional. Need a propane tank compartment? Try the 24-inch Octagon form with door. The Octagon fire pit form ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

FAQ
Why choose the Octagon Fire Pit Form over a square or circle?
Faceted geometry: the Octagon reads architectural from every seat, and its eight flat faces veneer as easily as a square while approximating a circle’s sociable shape. It is the pick when you want the finished pit to feel deliberately designed rather than default.
What sizes does the 16-inch Octagon Form come in?
Five footprints per the spec tab — 36×36, 48×48, 60×60, 72×72, and 84×84 inches — at 16 inches tall. The compact 36-inch Octagon suits courtyard patios; the 84-inch hosts a full ring of seating with fire at the center.
What is included beyond the shell?
The complete fire package: stainless steel drop-in pan, burner, key valve, whistle-free hoses, and a stainless steel air vent, matched to your Octagon’s size. The raw hardie board shell is ready for veneer — no separate component shopping required.
How is this different from the 24-inch Octagon with Door?
Height and access: this 16-inch Octagon keeps the fire low and lounge-friendly, while the 24-inch sibling stands taller and adds a built-in access door for reaching the valve and connections after finishing. Same eight-sided geometry either way.
Is this genuinely easier than building a fire pit myself?
Dramatically — the parts people underestimate (burner-to-pan sizing, ventilation, avoiding gas-line whistle) are already engineered into the Octagon Form. What remains is setting, veneering, and a licensed gas hookup: days of skilled work instead of weeks of research and rework.
What goes in the pan — glass or lava rock?
Either rated media works over the Octagon’s stainless burner: fire glass for sparkle and a modern read, lava rock for a natural, budget-kind look. Roughly a two-inch layer covers the burner; never substitute ordinary landscape rock.
Can we make s’mores over the finished Octagon?
Absolutely — its steady gas flame is the easiest s’mores fire there is: no smoke, no sparks, even toasting on all eight sides. Long skewers and drip control keep the media clean. See our gas fire pit range for more family-friendly formats.
