Factors such as your sauna's dimensions, windows, and type of heater (electric or woodburning) will determine the heated volume of your sauna. Note that the larger your sauna is, the more power is required by your heater to achieve bathing temperatures.
Preferred measuring system:
Knowing whether your sauna will be exposed to the seasons goes a long way when selecting a heater that will perform well all year long.

Select your sauna type:
An insulated sauna will have better heat retention than a non-insulated sauna, a factor which can affect a heater's performance.
Will the walls and ceiling of your sauna be Insulated?:
Glass has a higher thermal mass than wood and must be compensated for when selecting a heater.
Are there any windows or glass doors in your sauna?
The dimensions of a glass pane in a sauna directly correlates to the thermal mass of said glass panel.
How many windows or glass doors are in your sauna?
Tile and stone has higher thermal mass than wood and must be compensated for when selecting a heater.
Are there any tile, stone, or other non-wood wall or ceiling surfaces in your sauna?
The dimensions of a tile, stone, or other non-wood surface in a sauna directly correlates to the thermal mass of said tile, stone, or other non-wood surface.
How many tile, stone, or other non-wood wall or ceiling surfaces are in your sauna?
