Propane tank enclosure in GFRC concrete: a 16-inch cast stone cube with a lift-off lid
The Outdoor Plus propane tank enclosure in GFRC concrete hides your fire feature’s propane tank. This 16-inch-square cube stands 21 inches tall. Made in the USA, its glass fiber reinforced concrete feels and looks like cast stone at a fraction of the weight. It has small feet, a lightly pitted surface, and 18 concrete colors, including ash, limestone, and black.
The thick lid lifts off for tank changes. The box doubles as a low pedestal; no bowl is included. The hose runs unseen from the tank inside to your fire pit. Prefer steel or copper?

FAQ
How does this GFRC enclosure hide a propane tank?
It is a 16 by 16 by 21-inch concrete box with a removable lid — the 20-pound tank sits inside, the hose exits to your fire feature, and what guests see is a clean cast-concrete cube beside the seating. Lift the top off for swaps; SKU OPT-LPHIDEGFRC.
Removable top versus access door — why choose this one?
The lid-off design gives you the whole 16-inch opening from above: tanks lift straight out, regulators connect in open view, nothing threads sideways through a doorway. The trade is that the top must stay liftable — do not set potted plants and drinks on it permanently.
How many finishes can I get the tank enclosure in?
Eighteen listed GFRC finishes, running Ash through Vanilla — Black, Bronze, Chestnut, Chocolate, Copper, Limestone, Moss Stone, Natural Gray, Pearl, Rustic Gray, Rustic White, Silver, Slate and more. That palette exists so the OPT-LPHIDEGFRC can match the concrete feature it serves.
What is GFRC, and why use it for a tank cover?
Glass fiber reinforced concrete — cast concrete strengthened with embedded glass fiber, delivering the stone-look mass of poured concrete at far less weight. For an enclosure that gets placed by hand next to finished landscaping, and matched to concrete fire pit features, it is the obvious material.
Does a fire bowl or burner come with it?
No — the spec says bowl not included, and the enclosure itself produces no flame. It is the quiet half of the system: the fuel hides here while a separate TOP bowl, table or burner does the burning. Pair it at order time so finishes align.
Can the tank connect to a feature several feet away?
Yes — that is the normal arrangement: the enclosure sits discreetly to the side while a whistle-free hose runs to the feature’s valve. Your installer determines routing and length; keep the hose protected from traffic and heat, and the OPT-LPHIDEGFRC just looks like sculpture.
Is it safe to enclose a propane tank in concrete?
Designed correctly, yes — this enclosure is purpose-built for LP storage with a removable top rather than a sealed cavity, and your installer will site it to local LP rules: upright tank, reachable valve, ventilation preserved. It hides the tank; it never imprisons it.
