Bathroom Exhaust Fan Venting Options

There are two common ways to route ductwork to vent bathroom air outside: through the ceiling and out through an exterior wall, or through the ceiling and out through the roof. (You can also buy a fan that vents directly through an exterior wall, but this typically requires running a new electrical line to the wall.) Of the two ceiling options, a vent through a wall is less likely to leak.
