It is possible to order a hearth made to your own specifications to cover an existing cut out in a carpet or flooring. 1. Simply measure the length and depth of your current cut out 2. Measure the overall height from the floor of the hearth 3. Remember to always mention if the hearth will be used for gas Fireplaces, Electric Fireplaces, or for a solid fuel appliance (either a log burner or burning coal or logs) as this will affect the way the hearth is constructed. 4. Bespoke hearths should not cost a fortune as they are often made from the same if not less material then standard sized hearths. We recommend that you shop around for prices and select a supplier who is actually making the hearth rather that a middle man.
