Outdoor hearths are a great addition to any home and are available in both small-scale and large-scale designs. Small-scale hearths may include chimineas, fire rings, portable heaters or grated burning barrels. Small hearths can cost anywhere from $200 to $600, depending on the design. Larger scale hearths can be erected on your patio as free-standing structures or can be attached to your patio for year-round use. Larger hearths are often made of colored brick or tile, and are more intricately designed than smaller hearths. Larger hearths can cost anywhere from $2,000 to $10,000 depending on the design of the hearth.
