How concrete fire pits handle heat

Most pieces use glass-fiber concrete (GFRC), a thin shell reinforced with glass fibers. It looks like stone at a fraction of the weight of poured concrete. A stainless steel burner pan keeps the gas flame off the shell. The concrete is made for outdoor rain, sun and cold.

Choose your shape, size and color

Choose round for a circle of chairs, square for four-sided seating or rectangular for a sofa. A concrete fire bowl suits a pool wall; a concrete fire pit table adds a flat top at coffee table height or dining height. Sizes range from 24-inch bowls to 96-inch troughs. The Outdoor Plus offers 18 colors cast all the way through. American Fyre Designs offers seven colors, plus reclaimed-wood looks. Grand Canyon Gas Logs offers three stock colors. Most concrete pieces here come from The Outdoor Plus, with 80 of the 140 pieces, and American Fyre Designs, with 54.

Propane or natural gas?

Most pieces offer either fuel; a few tables are propane only. Your order sets the fittings. Compare gas fire pit choices, or choose a concrete fire pit on natural gas to connect to your house gas line without a tank. A few smokeless models burn firewood instead.

Frequently asked questions

Does concrete make a good fire pit?

Yes, when it's cast for the job. These reinforced shells give you the look of cast stone in a lighter form. In the gas models, a stainless steel pan holds the flame above the concrete, with no ash left behind.

Will a concrete fire pit crack?

Ordinary concrete can crack when trapped water becomes steam under a direct wood fire. These reinforced shells are built for heat and weather, with the gas burner in a separate steel pan. Keep the pan dry with a cover or lid between fires.

Can I put a fire pit on a concrete patio?

Yes. A concrete patio or pavers suit these gas models, with no falling embers and the flame contained above the surface. Set yours level, follow the manual's distances from walls and overhangs, and keep the gas line or hose out of walkways.

Can I make my own concrete fire pit instead?

You can, but a wood fire directly on poured concrete can crack it. Water trapped in blocks or river rock can turn to steam and cause bursting. A metal liner and gravel drainage matter. These cast gas features keep the flame above the shell instead.
