As long as I do it, I have no problem. But eventually the offspring will shower themselves and you can imagine how much value a teenager places on dampness and mold :p
Yes, that's right. You can always still install a decentralized ventilation system in the bathroom... Or link Internet access to ventilation... That should work. The consistent enforcement will be more of the problem.
Insanity, I'm glad about the [Kontrollierte-Wohnraumlüftung], we actually never ventilate the bathroom and bedroom manually in winter. Humidity constant at 45%. Only the kitchen I have to ventilate constantly, we cook a lot and our recirculation extractor hood is useless for odors...[Kontrollierte-Wohnraumlüftung] too...
