The Outdoor Plus Trilogy Fire Pit Form - 16” Tall - Ready to Finish

Trilogy Fire Pit Form, 16 inches tall: a low corner-shaped shell for your own finish

The Outdoor Plus Trilogy Fire Pit Form is a 16-inch-tall, ready-to-finish quarter-circle shell that fits a patio corner, with its curved face toward seating. Choose 48, 60, 72, or 84 inches. Finish its raw hardie board body with stone, tile, or stucco to match your space.

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. Using standard patio chairs? The 24-inch Trilogy form raises the flame. The Trilogy fire pit form ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

FAQ

What shape is the Trilogy Fire Pit Form?

A distinctive three-sided silhouette — the only triangular footprint in the Ready to Finish line. Finished in stone or stucco, the Trilogy reads as deliberate landscape sculpture, and its geometry tucks into corners and angled patio layouts where squares and circles waste space.

What sizes does the 16-inch Trilogy come in?

The spec lists 48-, 60-, 72-, and 84-inch footprints (part number pattern OPT-TGYRTF), with this listing covering the 16-inch-tall profile. Dimensions for each size are on the linked Trilogy spec sheet — worth a look, since the three-sided footprint measures differently than a square.

Does it ship with the fire system?

Complete: stainless steel drop-in pan, burner, key valve, whistle-free hoses, and stainless steel air vent, fitted to the Trilogy’s geometry. That matched-to-the-form engineering is exactly what is hard to replicate when building an unusual shape from scratch.

Is an unusual shape harder for my contractor to finish?

Not meaningfully — the Trilogy’s faces are flat hardie board planes that take tile, stone, stucco, or brick with standard methods. The three corners need mitering care, but that is trim work, not engineering. The dramatic result usually justifies the extra cuts.

What is the appeal versus just building a normal fire pit?

Anyone can search how to build a fire pit and end up with a circle of blocks. The Trilogy Form delivers something guests have not seen — an engineered triangular fire feature — with less labor than the ordinary DIY route, because the fire system arrives solved.

Which ignition and fuel configurations exist?

Liquid propane or natural gas, set at order, with Match Lit, Match Lit with Flame Sense (LC certified), Flame Sense with Spark, Low Voltage Electronic, and Plug and Play (CSA certified) ignition options per the spec tab. All arrive factory-configured in the Trilogy.

What media looks right in a triangular pit?

Fire glass plays up the Trilogy’s sculptural modernity — bronze or black glass against a stone veneer is striking — while lava rock keeps it grounded and organic. Either rated media works over the included stainless pan; see our gas fire pit collection for pairings.

The Ready to Finish Collection

A built-in look, without building from scratch — fire features you finish with stucco, stone, tile or brick to match your outdoor space.

Why Ready to Finish?

One Unit, Any Look You Want

Ready-To-Finish (RTF) fire features arrive as complete, ready-to-run units — burner, pan, ignition and vented enclosure already built — with a paintable, finish-ready exterior. Crafted from durable cement board, they give you the flexibility to personalize your outdoor space: dress the unit in stucco, stone, tile or brick so it looks custom-built into your patio, in a fraction of the time a masonry build would take. The stone-wrapped fire pit in the photo above is exactly that — an RTF form with a finish applied.

Finish It Your Way

The cement board exterior is made to be clad — stucco, stone veneer, tile or brick — so the finished piece matches your hardscape perfectly.

Built to Last

Durable cement board construction, made in the USA by The Outdoor Plus — long-lasting durability you can always count on.

304 Stainless Inside

Every RTF product features a 304 Stainless Steel pan and burner for enduring, reliable performance season after season.

Your Configuration

Choose your size, your ignition — from match lit up to plug & play electronic — and liquid propane or natural gas.
