Hello,
a practical question for you all. I hope this is the right forum section for it? If not, please feel free to move it, thanks.
We have an interior bathroom, so without a window. There is a ventilation fan that always turns on when the skylight is switched on. After bathing or showering, I sometimes feel the ventilation time is too short if I don’t leave the skylight on longer. Are there any guidelines that might help balance room size, duration, and humidity?
Best regards, Gerda

Hi Gerda, you can find information about this in the regulations of DIN 18011 and DIN 18022. For example, a bathroom without a toilet must be 4.5m² (48.4 ft²) or a bathroom with a toilet 5.5m² (59.2 ft²) in size. From there, you can also calculate how large your ventilation fan should be to remove moisture from the room.

Angelia-13 Feb 2014 15:05I once lived in an apartment like that, and to be honest, the interior bathroom never really smelled good, not even with a proper exhaust fan. I was relieved when my new apartment had a bathroom with a real window. Although it was just a skylight, it was still better than relying solely on ventilation fans.

Yes, a bathroom without a window is really inconvenient. You basically have to keep the door open all the time and keep the light on while bathing. I can’t provide exact figures; you’ll need to consult a professional for that.
Good luck with it.
