How tall should a raised hearth be?
Considering this, does a hearth have to be raised?
The perimeter of the hearth should be clearly defined by either using a raised edge or by raising the level of the hearth in relation to the floor. The hearth should extend at least 150mm out from the stove at the sides and 300mm in front.
Regarding this, what is a raised hearth?
A hearth is a fireplace's brick or stone floor. Some fireplaces are designed so that the hearth extends out into the room. A sitting-height hearth is simply a hearth that extends out into your room and is built up, or raised off the floor, to a height that is comfortable for people to sit on.
Granite is the best fireplace hearth material for solid fuel burning fires. However, to withstand the heat, you need to get one that has been 'slabbed'. This means that it has been cut into pieces and mounted in concrete to give it space to expand as it heats up.
