That alone is insufficient. Think about the bathroom: the air will be hot and very humid. The walls would have to be way too hot to have a dew point that isn't reached when then hot&humid air cools down at the wall.

So you are left with reducing the humdity by airing out in some way (with windows, with a very non-airtight building, or using automatic ventilation). Or, of course, you can use a dehumidifier.
