Options for venting a bathroom exhaust fan include best to worst.

Gable wall bathroom fan.

You may be able to configure a short route. I recommend that my clients vent their bath fans out a gable wall if at all possible when not using an hrv or erv that is. When venting a bathroom exhaust fan make sure to vent the air to the outside rather than into your attic where it can cause mold and mildew to form. However bathrooms that are further from an exterior wall will usually have a longer more complex route.

If you vent through a soffit where attic vents are often located the moisture will get sucked back up into the attic or roof venting. Through the roof or an exterior gable wall. Crawling in the attic revealed the connection of four bath fans into one long duct going to a gable vent. Ductwork is what will connect the fan to the outside.

To do so means that the duct would be run up to the vent. An exhaust vent fan can exhaust out through a gable end side wall or out through a soffit overhang. And of course a bathroom with a window doesn t require an exhaust vent. Keep mirrors from fogging up with a bathroom exhaust fan.

The resistance to the airflow in the long duct caused the air to back up in the nearest bathroom especially when more than one fan was on at the same time. The location of the bathroom will determine how extensive the ductwork will be. Condensation will run down and rust the fan and stain the ceiling.
