Start a fire and what happens next is magical. Once a fire is lit in your backyard, that's where the party goes. And today, there are more choices in hearth products than ever before. Outdoor fireplaces, permanently installed, on your patio or outdoor room, bring the same kind of charm and ambiance as they do inside. Usually made of stainless steel, these fireplaces can be surrounded by granite, tile, stone or any material that complements your home's architecture and style. Outdoor fireplaces usually don't require a chimney and can use either natural gas, propane or wood.
