I got the impression that you don't have to tape the door frames NOW, but save the tape (and your beautiful wallpapering job) for only if there is a need. Is this correct, as far as you know?
Thanks for any helpful input.
As far as which room to pick, why not be prepared to use both of them? Normally, I would say use the bathroom as the walls are somewhat reinforced by the presence of water pipes as well as having the benefit of being, well, the bathroom.
However,not knowing the layout of your home, it's impossible to make a cogent recommendation.
The important thing is that you make some kind of plan, and practice it with your family. Most people won't even take the most basic of precautions so you and yours will be miles ahead if the excrement ever contacts the rotating oscillator.
