If you prefer a concrete fire table, we offer two ways to fuel them: natural gas and propane. Inside each, you’ll find nonflammable lava rock and decorative beach stones over a burner mechanism. Our aluminum propane fire pits contain pumice stone and lava rock. If you order the natural gas concrete fire table, it works similarly to a gas fireplace; if you’re used to a propane grill, you’ll have no problem managing a propane fire table or fire pit. We even sell an additional decorative propane tank enclosure as a companion to our concrete fire tables to discreetly cover your propane tank. Our fire tables don’t require wood or kindling of any kind, and you don’t have to clean or store a stainless steel bowl. Just keep in mind that because the stones are designed to be in our fire tables and fire pits permanently, our fire tables aren’t designed for cooking. To keep leaves and other debris out of your fire table, it’s also a good idea to cover it when it’s not in use, after you cool it down.
