Where does a bathroom fan vent to?
Bathroom fans are vented via installed ductwork, either straight up to the roof with a roof vent cap, or they are vented out below the roof overhang. Ensure ductwork deposits the moisture out of the house and not into the attic, as this will cause mold and moisture accumulation.
Do bathroom vents have to vent outside?
Bathroom fan installation requires outside ventilation. If the fan isn’t accessible through an attic, you’ll need to vent through a sidewall of your house.

Are bathroom vents in houses connected?

How do air vents work in apartments?
Fresh air inlets are used to allow air into the building, where the air is routed through a system of air ducts into a supply fan. The fan boosts the pressure of the air and supplies it to the rest of the building. Exhaust fans in the ceiling are then used to expel old, stale air to the outside of the building.
Is it better to vent bathroom fan through roof or soffit?
Whether it’s new construction or a remodel, a bathroom vent should always vent through the roof instead of an eave, overhang, or soffit. The point of a bathroom exhaust vent, or any vent really, is to remove hot, moist air from the house. Over time, this can lead to mold, mildew, and other damage to the roof structure.
How do you know if you have soffit vents?
The only way to be sure is to crawl up into the attic and go near the roof edge to see if you can see any daylight indicating open soffit venting. You might see a little light where the roof sheathing meets the fascia board but that might be it.

Are all bathroom vents the same size?
Bathroom vent fans are rated for the amount of air they can move, measured in cubic feet per minute, or CFM. Standard fan sizing applies to bathrooms that are 100 square feet or less. The minimum allowed fan size is 50 CFM, so if your bathroom is, for example, only 42 square feet, you still need a 50 CFM fan.
