Bathroom ventilation codes require a bathroom exhaust fan to vent to the exterior not the attic for health and structural reasons.

In attic bathroom vent fan.

The bathroom exhaust ventilation fan disperses air through an opening in the fan housing which is usually 3 inches in diameter and ideally faces in the direction of the ventilation system outlet. You should never exhaust the bathroom fan directly into the attic. Before you rush to the attic or go the roof to check for any leaks make sure the exhaust fan duct is properly insulated and run the fan more frequently for a prolonged period. Both bathrooms are vented by a single in line fan that has one exhaust vent running through the roof.

No you should not vent a bathroom fan directly into an attic. Bathroom fan sound levels sone rating refers to the sound level of a fan. Options for venting a bathroom exhaust fan include best to worst. It seems like such an easy solution just leave a bathroom vent hose in an attic.

While insulating you can make some mistakes. Each bathroom has its own exhaust fan. Wall mount fans are mounted on an external wall of a home and are used if there isn t a way to vent through the roof as in the case of a bathroom on the first floor of a home. Let me tell you.

One in line centrifugal fan can be mounted in the attic to exhaust the moisture from two bathrooms. It s all outdoor air anyways right. Surprisingly bathroom fans are not required by some building codes. To avoid mistakes not running it at all consider installing switches with built in timers.

All municipalities have different requirements but some do not draw a hard line on requiring exhaust fans. Through the roof or an exterior gable wall. 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.

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. No you cannot vent your bathroom exhaust fan into the attic. Bathroom code does address the issue of moving odor and moisture laden air from the bathroom to the outside. Each fan vents separately out the roof.

Your attic is not a temperature controlled environment is never the same temperature as your living space and generally closer to the temperature outside. A 3 or 4 inch duct connects to the outlet on the fan housing and runs to a side wall or to the roof and connects to a vent cap that allows the exhaust to disperse outdoors. However you can vent a bathroom fan through an attic while it terminates on the roof or gable end. Ceiling fans vent either into the attic or outside through the roof.
