A sunken fire pit lives or dies by its insert. Drop a flimsy bowl into a paver-lined pit and you’ll be replacing warped steel by spring. The five picks below are rings and bowls that hold up when set into ground-level or in-ground builds. Before you dig, read up on fire pit basics, the fire pit table format, what size fire pit do i need? a sizing guide, gas vs wood burning fire pit, and smokeless fire pit design so your excavation matches your hardware.
How We Evaluated
I assessed steel gauge, rim diameter, air-vent geometry, and rust behavior against ASTM G154 UV-exposure benchmarks and each maker’s stated warranty. Wall thickness and heat-cycling tolerance mattered most, since sunken installs trap moisture against the metal.
1. SoulMate Outdoor Fire Pit Ring — the true in-ground insert
This one wins for sunken builds. The SoulMate ring runs 40 inches on the outer rim and 36 inches inner, so it drops cleanly into a paver or stone surround with a mounting lip. Solid steel construction and a smokeless twin-wall air system pull secondary combustion up through the rim. No floor means water drains straight into the gravel base you’ve dug, which is exactly what an in-ground pit wants. If your project is a real sunken seating well, this is the shape you build around.
2. Fire Beauty Fire Bowl with Spark Screen — the full kit for shallow wells
Fire Beauty bundles a steel bowl with a spark screen, log grate, and poker, so a shallow sunken well gets everything at once. The screen matters when your pit sits low and embers ride the wind toward seating. The bowl floor holds ash but needs drilled drainage before you sink it, or rain will pool. Good for a paver ring where you want a contained bowl rather than an open ring. Review how to clean a fire pit before the screen and grate collect a season of creosote.
3. GasOne 23-Inch Wood Burning Fire Pit — the compact backyard drop-in
At 23 inches, the GasOne fits tight patios and small paver circles where a 40-inch ring won’t clear. It’s built from alloy steel and runs wood, so a modest excavation with a gravel bed handles it. The narrow diameter concentrates heat, which suits two or three chairs rather than a crowd. The honest trade-off is capacity. If you host six people, size up. For a corner of a small yard, this compact footprint sinks in without dominating the space.
4. OutVue 26-Inch Fire Pit with Grill and Lid — the cook-and-cover hybrid
OutVue adds a swing-away grill grate, a lid, a waterproof cover, and a poker to a 26-inch wood-burning bowl. The lid and cover earn their place in a sunken install, since a low pit fills with leaves and rain fast. Use it as a fire pit table surface with the lid on, then cook over the grate when you want it. It ships as a bowl, so drill drainage before you sink it. Best for anyone who wants one piece doing fire, food, and a flat top.
5. Zzuvjoy 36-Inch Fire Pit Ring — the ventilated smokeless ring
Zzuvjoy runs a 36-inch steel ring with air vents feeding a smokeless burn. Like the SoulMate, it’s a rim rather than a bowl, so it suits an in-ground build with a drainage base. The vent placement pulls air low and pushes cleaner combustion, which cuts the smoke that hangs in a sunken well with poor airflow. It’s a large gathering ring, so plan a wider seating radius. A solid alternative if the SoulMate is out of stock.
Comparison Table
| Pick | Size | Type | Key extra |
|---|---|---|---|
| SoulMate | 40 in outer / 36 in inner | Smokeless ring | True in-ground lip |
| Fire Beauty | Standard bowl | Wood bowl | Screen, grate, poker |
| GasOne | 23 in | Wood bowl | Compact alloy steel |
| OutVue | 26 in | Wood bowl | Grill, lid, cover |
| Zzuvjoy | 36 in | Smokeless ring | Air-vent geometry |
How to Build a Sunken Fire Pit Around Your Insert
Excavate at least 12 inches below grade and lay 4 to 6 inches of gravel for drainage. A ring insert like the SoulMate or Zzuvjoy sits on a retaining course of fire brick or paver blocks rated for high heat. Keep the burn surface a minimum 10 feet from structures per common ASTM fire-clearance guidance. Bowls need drilled weep holes so trapped water can’t rust the floor from below. Slope the surrounding grade away from the pit so runoff never pools in the seating well.
Rings vs Bowls for Sunken Installs
Rings win for permanent in-ground pits. With no floor, water drains through the gravel base and the steel dries between uses, which slows rust. The SoulMate and Zzuvjoy are ring inserts built for this. Bowls like the Fire Beauty, GasOne, and OutVue contain ash and travel well, but sunk without drainage they hold moisture against the metal. If you want portability later, choose a bowl. If the pit is a fixed landscape feature, choose a ring.
Frequently Asked Questions
Do I need drainage under a sunken fire pit?
Yes. Dig 4 to 6 inches of gravel below the insert so rain drains away instead of pooling. Standing water rusts steel from below and can crack surrounding pavers during freeze-thaw cycles.
Are ring inserts better than bowls for in-ground pits?
For fixed installs, yes. Rings have no floor, so water drains through the base and the steel dries out. Bowls trap moisture unless you drill weep holes before sinking them.
How far should a sunken fire pit be from the house?
Keep a minimum 10-foot clearance from structures and overhanging branches, in line with common ASTM fire-safety guidance. Sunken pits sit low, so ember drift near seating is the bigger concern.
Can these steel inserts handle freeze-thaw cycles?
Solid and alloy steel rings tolerate heat cycling well, but standing water is the enemy. Proper gravel drainage below the insert prevents the moisture that drives rust and warping over winter.
Which pick suits a small patio?
The 23-inch GasOne. Its compact alloy-steel body drops into a tight paver circle and concentrates heat for two or three chairs without dominating a small yard.
Do smokeless rings actually reduce smoke in a sunken pit?
They may help. The twin-wall air vents on the SoulMate and Zzuvjoy feed secondary combustion, which burns off particulate. Airflow in the seating well still matters, so avoid enclosing the pit on all sides.
Bottom Line
The SoulMate 40-inch ring is the pick for a genuine sunken build. Its no-floor design drains through your gravel base and the 36-inch inner rim seats cleanly into stone. Choose the OutVue 26-inch if you’d rather have a portable bowl that grills, covers, and doubles as a flat top. One honest caveat: every bowl here needs drilled drainage before you sink it, or trapped rain will rust the floor within a season.
