I have a relatively small bathroom and there is no fan to suck up the steam from the shower. We've been leaving the window open but that .
If your bathroom does not have an exhaust fan, you can expect a heavy mist inside the bathroom when you take a shower. An exhaust fan pulls this moisture out .
No window, but the bathroom does have an AC vent which works.. . There are old homes without windows or fans and they aren't illegal .
At the first day I move in, I realized that the vent fan in the bathroom is not working
