Are you wondering how to build a Finnish sauna of your own? Read these tips already before you begin the building so you’ll know how to start your project.

  1. Consider where your sauna should be located. Will you build your sauna inside your house, or would a backyard sauna be more appropriate?
  2. Think about how you intend to use your sauna. How many people will be bathing at once? Saunas often accommodate three or four people at a time. Take your time when considering the kinds of situations where you would like to use your sauna.
  3. Always work with professionals when planning a sauna. Saunas need to be both insulated and waterproofed. Remember: professionals should always design the layout of the sauna and the plans for its ventilation and electricity—as well as its construction. See here a selection of sauna companies and experts in sauna construction.
  4. Carefully consider your choice of sauna heater so you can be sure to purchase a heater that is appropriate for your preferences and needs. Do you want a wood-burning heater or an electric heater? Both will require professional help to install. An electric heater requires a high-voltage outlet, and a wood-burning heater requires a chimney and firesafe conditions. It’s also a good idea to think about what kinds of sauna temperatures and löyly you prefer.
  5. Be sure to consult with professionals when planning your sauna. Building a sauna requires special care and professional skills.

Here is a brief overview of the sauna build process:

  • The structures around the sauna are sealed against water and moisture to prevent damage. The floor of the sauna needs to be waterproofed, and it’s a good idea to install a floor drain. The sauna should be installed in such a way that no water comes in contact with untreated wood. You should use water-resistant materials in the sauna, including for the sauna’s structural elements.
  • The sauna must have good air circulation, and the ventilation system must comply with local requirements. Good airflow ensures that there will be enough oxygen in the sauna. Is there a ventilation system in the building already? How to handle air intake and exhaust? If you will be using a mechanical ventilator or other ventilation system, ensure that it is working properly.
