Definition

The chamber in a fireplace that contains the fire. It is usually lined with firebrick so it can withstand the extreme heat that it is exposed to. Manufactured fireplaces have fireboxes made of sheet metal.

Things you need to know

A firebox not only has to withstand the extreme temperatures of a fire, it must also be able to withstand the expansion and contraction that happens when the firebox heats up and cools off.

Cost Considerations

A factory-built fireplace costs about $2,000 to $5,000, making it a more affordable option than adding a masonry fireplace, which can cost $10,000 or more. It is also less expensive to repair.

Costs vary greatly by region (and even by zip code). To get free estimates from local contractors, please indicate yours.
