Workshop stove hearth

If you have a concrete or other masonry floor then a hearth is still a good idea to give a visible delimited zone around the stove. This means that you can easily keep the hearth clear from combustible materials that could otherwise come close to the stove.
If you have a wooden floor (or another type of combustible floor) then you need to protect the floor from the heat of the stove. This can be effectively done with a thick hearth of non combustible material such as slate, flagstones, concrete, etc. We recommend that the hearth extend 150mm to the sides and back and 300mm to the front of the stove.
