FireScapes' portable outdoor fireplaces can be installed anywhere that you can safely connect to LP or natural gas – such as your porch, deck, patio or poolside. Manufactured stone with white, creams and grays. Approximately 1/2" gray mortar between stones. Honed, blue-gray slate cap. The design of a 2 1/2" space between the inner and outer walls keeps any material that can be applied with motar safe from the heat of the fire. The suspended floor creates a natural draft like a fireplace, and in turn keeps the undercarriage cool and safe to burn on any outdoor surface.
