Is it finally time to install some extra quality of life in your bathroom? In a series of articles we will give advice on the most important things to keep in mind when planning for your new sauna.


Magnus Karlsson works at Tylö's customer service department and responds daily to questions about everything related to sauna installations. He emphasizes ventilation as an important factor that many people tend to forget about in the planning process. 

- When you’re building a sauna, ventilation is key. If you do not plan for it from start, it may cause you problems that are difficult to straighten out afterwards, Magnus says.

 Ventilation in a sauna has a dual function; to keep the air fresh and to spread the hot air in the sauna. It is therefore important already from an early stage of planning to decide where to place the vents, since this affects the design of the entire sauna room.

 - The ideal is to place the in-air under the heater and the out-air as high as possible on the opposite wall, that way you spread the heat most efficiently, Magnus says.

Keep this in mind when planning the heater’s location, so that you don’t choose a wall facing, for example, a shower room or an exterior wall, but rather choose a wall facing the bathroom. 

- It is important to keep the entire ventilation within the bathroom; the air must both be taken in and let out there. If you instead let out the sometimes humid sauna air to the rest of the house you risk disturbing the regular ventilation, Magnus says.

 In wintertime you can however gladly let the sauna door stay open after you have completed your bath and let the excess heat warm up the rest of the house, this way you take maximum advantage of the hot air.
