A double wall fire pit pulls cool air between two steel layers and pushes it back out as secondary combustion. Less smoke, more heat. Before you buy, cross-check our guides on smokeless fire pit design, stainless steel fire pit longevity, what size fire pit do i need? a sizing guide, how to clean a fire pit, and the eternal gas vs wood burning fire pit debate. Five picks below, ranked by airflow engineering and steel gauge.
How We Evaluated
I ranked each unit on wall-gap airflow design, steel thickness, corrosion resistance per ASTM B117 salt-spray benchmarks, and real backyard fit. Portability and cover inclusion broke ties.
OutVue 36 Inch Fire Pit with 2 Grills - 3-in-1 Wood Burning Fire Pit Table for Outside Patio & Backyard
Pros
- 3-in-1 design replaces bonfire, grill, and patio table
- Swivel grills adjust to any height and rotate 360 degrees
- Holds 20 lbs of wood for strong, long-lasting fires
- Mesh vents prevent sparks from escaping while improving airflow
- Comes with fire poker, cover, and replacement part support
Cons
- No customer reviews yet to confirm durability claims
- 36-inch footprint may overwhelm small patios or balconies
- Assembly requires not tightening screws until all pieces connect, which takes patience
This fire pit solves the biggest problem with outdoor entertaining: where do you put everything when the fire goes out? Instead of dragging out a folding table or letting your patio look like a storage yard, you flip the lid and suddenly have a 36-inch round table that seats up to 8 people. We love that it thinks past the bonfire moment and gives you a piece that works for Saturday morning coffee, Sunday afternoon grilling, and evening s'mores without rearranging your deck.
The swivel grills are smarter than most fixed grate designs. You can rotate them away from the flames to keep food warm, swing them over high heat for searing, or remove them completely when you just want a cozy fire. The geometric cutouts aren't just decorative either; they let air flow through to keep the fire strong while casting shifting light patterns across your patio stones after dark.
If you want a backyard fire feature that earns its space by doing three jobs without looking like a gimmick, this one delivers.
Styles it works with: Modern Farmhouse, Industrial, Rustic Contemporary, Transitional Outdoor
Best placed in: Center of patio seating area, backyard firepit zone with Adirondack chairs, poolside gathering space, large deck with outdoor dining setup
May not suit: Apartment balconies or small patios under 10x10 feet where 36 inches dominates the space, homes with toddlers due to open flame and hot surfaces, HOAs or municipalities with strict open fire regulations
Buy it if:
- You host outdoor gatherings regularly and need flexible seating and cooking options
- You want one piece that works spring through fall instead of seasonal storage juggling
- You have a patio or deck with at least 8x8 feet of open space for safe fire clearance
Consider waiting if:
- You want to see verified customer reviews before committing at this price point
- You need a specific finish color and want to wait for more options
Skip it if:
- You live somewhere with year-round fire bans or strict smoke ordinances
- You need a compact fire pit under 30 inches for a small balcony or courtyard

1. HGD 19.8 Inch Smokeless Firepit — the pack-and-go patio winner
This one wins for anyone short on space. At 19.8 inches, the HGD stainless steel body runs the classic double wall secondary-burn loop, drawing air up through the base and venting it through the top rim. That cuts visible smoke noticeably once the fire reaches temperature. It ships with a grill grate, so it doubles as a camp cooktop. Stainless resists rust better than painted steel under repeated freeze-thaw. The trade-off is capacity. Small logs only, and a tight burn chamber that needs refueling often. Best for balconies, campsites, and solo evenings.
2. Fruyyzl Smokeless Fire Pit Ring Insert 48 Inch — the big-gathering liner
At 48 inches, the Fruyyzl is a ring insert, not a standalone bowl. You drop it into an existing masonry or stone pit to add the airflow holes that make double wall combustion work. Durable steel construction with a perforated inner wall feeds oxygen to the flame for cleaner burning. This is the pick for large built-in pits where a small portable bowl looks lost. No grill, no cover, no legs. You supply the surround. If you already poured a fire ring foundation, this upgrades it cheaply.
3. OutVue 36 Inch Fire Pit with 2 Grills — the full-kit backyard hub
The OutVue arrives as a complete set. A 36-inch wood-burning bowl, two grill grates, a lid, a poker, and a round waterproof cover. That bundle is the reason it earns a spot. You’re not buying accessories separately. The 36-inch diameter seats a proper log stack for group nights. The included cover matters for corrosion, since standing water is what kills painted steel fastest. Assembly takes patience, and the finish is coated rather than stainless, so keep it covered off-season. A strong turnkey choice for families.
4. BPS 36″ Smokeless Metal Fire Pit Ring — the drop-in insert with heft
The BPS pairs a 36-inch outer ring with a 30-inch inner steel insert. That double-layer gap is the airflow engine, channeling oxygen up the walls for a cleaner burn. Like the Fruyyzl, it’s an insert meant for an existing surround. The 6-inch difference between outer and inner diameters gives a solid air channel. Metal construction holds up to repeated high heat. There’s no cover or grill in the box. If you want a mid-size ring with a generous burn chamber, this fits between the compact HGD and the oversized Fruyyzl.
5. SoulMate 35-Inch Outer/31-Inch Inner Fire Pit Ring — the tight-gap efficiency play
The SoulMate runs a 35-inch outer and 31-inch inner ring in solid metal steel. The narrower 4-inch wall gap accelerates airflow velocity, which can improve secondary combustion at the top rim. It’s a round rim insert for masonry surrounds, same install logic as the BPS and Fruyyzl. Heavy-duty steel resists warping under sustained heat. No grill or cover included. Choose this if your existing pit opening lands near 35 inches and you want the tighter, faster-burning geometry over a wider air channel.
Comparison Table
| Pick | Size | Type | Extras |
|---|---|---|---|
| HGD | 19.8 in | Standalone bowl | Grill grate |
| Fruyyzl | 48 in | Ring insert | None |
| OutVue | 36 in | Standalone bowl | 2 grills, lid, cover, poker |
| BPS | 36 in / 30 in | Ring insert | None |
| SoulMate | 35 in / 31 in | Ring insert | None |
How to Choose a Double Wall Fire Pit
Start with format. A standalone bowl like the HGD or OutVue works anywhere. A ring insert like the BPS, Fruyyzl, or SoulMate needs an existing surround. Measure your opening first. Then check the wall gap. A wider channel, roughly 5 to 6 inches, moves more air volume, while a tight 4-inch gap moves it faster. Both feed secondary burn.
Steel type drives lifespan. Stainless resists rust without paint. Coated steel needs a cover, since standing water triggers corrosion per ASTM B117 salt-spray findings. Wirecutter and Apartment Therapy both flag cover inclusion as a real value marker.
Standalone Bowl vs Ring Insert
A standalone bowl gives you legs, a floor, and often a grill or cover in one box. That’s the OutVue and HGD path. You unbox, assemble, and burn. A ring insert is just the airflow rim. It’s cheaper and lighter, but you supply the stone, block, or masonry surround around it. That’s the BPS, Fruyyzl, and SoulMate route.
Match the choice to your yard. Renters and campers want the bowl. Anyone with a poured fire ring foundation wants the insert. Sizing matters more for inserts. A 48-inch Fruyyzl won’t seat in a 36-inch opening.
Frequently Asked Questions
How does a double wall fire pit reduce smoke?
Cool air enters the base, heats between the two steel walls, then vents through top rim holes. That superheated oxygen reignites unburned particles, called secondary combustion. Dry, seasoned wood matters. Wet logs still smoke regardless of airflow design.
Is stainless steel worth it over coated steel?
Stainless resists rust without paint, which matters through freeze-thaw cycles. Coated steel performs fine if you keep it covered and dry. Standing water drives corrosion fastest, per ASTM B117 salt-spray benchmarks. The HGD is stainless. Cover the coated bowls.
Can I put a ring insert in any fire pit?
Only if diameters match. Measure your surround opening before buying. A 48-inch Fruyyzl needs a large masonry pit, while the 35-inch SoulMate suits standard block rings. Mismatched sizing leaves gaps that ruin the airflow loop.
Do these need a special base or gravel?
Standalone bowls with legs sit on paver or gravel to protect grass and decking. Ring inserts rest inside a non-combustible surround. A few inches of gravel improves drainage and airflow under the fire either way.
How often should I clean the ash?
Empty ash after every two or three burns. Buildup blocks the base airflow holes that feed secondary combustion. Wet ash also accelerates rust inside coated bowls. See our full how to clean a fire pit walkthrough for stainless care.
Will a double wall pit work with a grill grate?
Yes. The HGD and OutVue include grates directly. Ring inserts don’t, but many aftermarket grates fit standard 30-inch to 36-inch openings. Cooking heat may reduce smokeless efficiency slightly since food drippings interfere with clean combustion.
Bottom Line
The HGD 19.8 Inch stainless bowl wins for portability, rust resistance, and an included grill, making it the safest all-around buy for tight patios and campsites. Step up to the OutVue 36 Inch if you host groups and want the lid, cover, and dual grates bundled. Both cut smoke well with seasoned wood. Ring inserts like the BPS and SoulMate save money, but only if your existing surround diameter matches. Measure first, then buy.
