How to check a tank really fits
Two measurements and one question. Do these before you buy, because the commonest complaint in this category is a cylinder that technically fits and then cannot be connected or removed.
- The standard 20 lb cylinder.This is the barbecue bottle, and it is what almost every unit here is designed around. It is roughly 18 inches tall and 12 inches across, plus the valve and regulator on top — and the regulator is the part people forget, because the fitting needs clearance above the valve to connect at all.
- The cabinet door opening, not the cabinet. A base big enough inside is no use if the access door is narrower than the cylinder. If the listing publishes a door or access dimension, check it against 12 inches plus room to maneuver.
- Can you reach the valve with the fire lit? This is the one that matters. You must be able to shut the gas off at the cylinder without reaching across or under a burning fire. If the access is on the opposite side from the controls, think about where the unit sits.
Where a listing does not publish its dimensions — and the BALI OUTDOORS table does not — treat that as a reason to buy from a seller with a straightforward return policy rather than as a reason not to buy. Our cards say “Not published” wherever the maker is silent.
The shapes, and which hides a tank
| Shape | Tank goes | Notes |
|---|
| Square or round fire pit table | Inside the base cabinet | The mainstream hidden-tank answer |
| Rectangular dining-height table | Inside the base cabinet | Longest flame, suits a long seating run |
| Fireplace with a storage cabinet | In the cabinet, stated on some listings | Directional heat instead of 360 degrees |
| Low-profile tabletop fire table | Usually outside, on a hose | Too shallow for a cylinder |
| Portable fire bowl | Outside, on a hose | By design — it is meant to be carried |
| Fire pit table with a chair set | Inside the table base | Cheaper than buying both separately |
If you want the tank hidden and the unit portable, those two wishes fight each other: a cabinet big enough for a cylinder is heavy and not something you carry. Pick one. The genuinely portable units, cylinder on a hose and all, are on portable camping fire pits.
BTU, size and what you actually feel
Three of the picks here publish an output figure, and the numbers are worth reading properly. The Ciays and the BALI OUTDOORS both state 50,000 BTU; the Endless Summer rectangular table states 40,000 BTU across a 44 by 32 inch body.
Higher BTU is not automatically more warmth where you are sitting, because a wider burner spreads the same output over a longer flame line. A 50,000 BTU burner in a 28-inch square concentrates heat in a tighter circle; 40,000 BTU across 44 inches gives a longer, lower, more decorative flame that suits people sitting along one side. Decide from your seating, not from the bigger number, and note that wind steals more heat from a wide shallow pan than from a deep one — which is why wind guards exist.
The other figure to respect is certification. The Ciays listing states CSA listing; where a listing is silent on certification, we say so. For a gas appliance with a concealed cylinder, a third-party listing mark is the single most reassuring thing on the spec sheet, and it is worth paying a little for. The full range, certified and not, is on best propane fire pits and best fire pit tables.
Living with a tank inside the furniture
A concealed cylinder is tidier and it introduces three small habits worth having.
Do not block the cabinet vents. Manufacturers put louvers or openings in these bases deliberately, because propane is heavier than air and any leak needs somewhere to go. Do not stuff the cabinet with cushions, covers or garden tools, and do not seal the vents to keep spiders out.
Check the hose and regulator when you swap the cylinder. Every exchange is a natural moment to look at the hose for cracks and abrasion, confirm the connection is tight, and leak-test with soapy water at the fitting. A hose inside a cabinet is out of sight, which means it is also out of mind.
Close the cylinder valve, not just the control knob. The control shuts the burner; the cylinder valve isolates the gas. When the fire is out for the evening, close the valve — and for storage over winter, disconnect the cylinder and keep it outdoors and upright, never in a garage, basement or shed.
The siting rules are unchanged by the tank being hidden. Smokey Bear’s published guidance for an outdoor fire is to clear at least a 10-foot diameter around the site, stay at least 15 feet from vegetation and low-hanging branches, and keep vertical clearance of at least three times the flame height. If there is a roof, pergola or pavilion above the patio, read fire pits under pergolas and gazebos before you buy — a low-profile table is the right shape for that situation and a tall fire column is not.
And buy a cover. A fire pit table is a horizontal surface with a burner in it, which means it collects rain, leaves and grit, and the burner ports are the part you least want blocked. The Ciays includes a lid; for everything else, our covers page is the place to start.
A note on the cylinder you have just hidden
Concealing the tank in a cabinet is a design win and it does not change the physics: propane is heavier than air, so a leak collects in the cavity rather than dispersing upward. Keep the designed vents clear, leak-test the connection with soapy water before the first fire of the season, and read are propane fire pits safe for the rest of the storage and lighting rules.
