Outdoor Masonry Fireplace Dimensions

Outdoor masonry fireplace dimensions.

Outdoor fireplaces can be as small as four feet tall three feet wide and two feet deep. I suggest 4 solid block for this purpose. Once your concrete footing has cured for 24 hrs or more you will need to build a level base on which to construct your firebox. The rear wall of the firebox rises vertically from the floor of the fireplace and then begins to slant towards the fireplace opening just at the top of the gas logs.

The firebox depth does not include the thickness of the facing material you see when looking at the fireplace. While larger fireplaces complete with mantel and hearth built in seating and wood storage boxes can be as large as 15 feet tall 15 feet wide and 4 feet deep. No time calculating firebox dimensions or thinking about draft details your contractor can simply focus on their artistry.
