> Mold is not a ventilation problem, but rather a moisture control problem. Keep the humidity down (especially with whole house dehumidifiers), and eliminate condensation points (by eliminating thermal bridging), and it goes away.

This sounds like one of those kinds of answers that only works with spherical cows in a vacuum.

If my shower were completely open and in the middle of the living room, perhaps. Alas, it's in a small private room that usually has the door closed while in use, and now we've circled back around to ventilation...

There are houses that are almost hermetically sealed, and do not have issues because they control temperature and humidity properly:
