I’ve just built a solid timber floored sauna and have purchased a free standing Narvi 20 wood burning heater for it. The firebox is only a mere 25mm (1”) off the floor (no inbuilt stand that raises the firebox). Struggling to find any info on thickness and materials for building the hearth. My presumption is given the lack of distance between firebox and timber floor, it’ll need to be quite thick.
Looking for suggestions.
