        If you live in a cold climate changing duct work to insulated flex ducting may be of help.

        With all the warm and moist air that goes through the 4" fan line, a lot of it is going to condense back into water. Not much you can do except route the 4" line so that most of it runs downhill to a gable or soffit exit point. Insulating the vent hose can help, but since it eventually will open to a 4" exit hole to the outside cold, it will still condensate and run back into the house if the majority of the hose runs uphill.

        I would make sure the duct line goes UNDER any insulation in the attic. This will help steam to not condense also. We have a vent in our main floor shower/bath room, and it is pretty level goes out to a soffit area and under the insulation. Have never had a problem with moisture.

        The right size vent fan (for the space) is important too, as it needs to move the volume of moist air fast.
