Installing a sauna: space, ventilation and electricity
A sauna typically occupies 3 to 5 square meters. Ideally, it should be placed near a water source, as alternating between heat and shower is an integral part of the ritual.
Three technical points deserve your attention:
- Ventilation : essential for renewing the air, extracting heat and controlling humidity outside the cabin.
- Insulation Good insulation limits moisture infiltration into the walls and reduces energy consumption.
- The power supply : a powerful model often requires a dedicated circuit, sometimes three-phase.
Allow for a ceiling height of at least two meters and leave a 5 to 10 cm gap between the cabin walls and the wall. Practical tip: leave the door open after use to prevent mold. If you have limited space, there are solutions for creating a compact space for your home sauna without compromising comfort.
