The air travels through ductwork that is connected directly to the ceiling vent. Another duct runs from the housing to the exterior of the home, again being, the roof, or overhanging soffit. The blower motor then propels the air from the housing unit through the ductwork connected to the exterior of the home.
You can mount a bathroom vent in two places: the wall or the ceiling. Ceiling vents should be routed through the roof or siding, but not into the attic. Installing a bathroom vent costs $240 to $560.
Bathroom fan installation requires outside ventilation. If the bathroom exhaust fan or venting fan isn't accessible through an attic, you'll need to vent through a sidewall of your house. If you're venting a bathroom fan through an external sidewall, then you'll need a wall mounted bathroom exhaust fan.
The most common configuration is to feed 2" PVC down from the ceiling within the wall behind the toilet. The vent pipe connects into the toilet drain pipe. The sink drain pipe and the tub/shower drain pipe are vented with 1.5" pipe that branches off from the 2" PVC mainline.
The best bathroom exhaust fans connect to your home's existing vent ducts and channel the moist air outside. Some types of bathroom fans only vent moist air to the space in between your ceiling joists or into an attic.

Air shall not be exhausted into an attic, soffit, ridge vent or crawl space.” It's always a good idea to also check local building code and the local building department. For proper bathroom ventilation it is best to run the ductwork from the bathroom exhaust fan vertically through the roof or out the side gable wall.
Did you know that bathroom exhaust vents discharging into your attic can cause mold? Moreover, it can cause water stains on your ceilings that could lead you to believe you have a roof leak. Bathroom vents should always be vented to the exterior of your home and it is required by code.
Apart from pushing cooled air into your room, air vents also draw warm air from your room back into the air ducts. This warm air is then transported back to the air conditioner, which is cooled again, maintaining an efficient air conditioning cycle.
Yes, the toilet and sink can share the same vent, as can the shower. It's common to have one main vent pipe for multiple fixtures, although you might need a larger pipe. You should check with local building and plumbing codes to confirm you'll have adequate piping for your home.
Signs that your bathroom needs more ventilation are:
Stuffiness when you enter the room. Mildew on walls or tiling. Stains forming on walls or ceiling. Smells that linger for a long time.
A duct on a bathroom exhaust fan needs to terminate so that the exhaust air goes all the way to the outdoors. That could be through a roof, a gable end, or a soffit.
Yes, every bathroom needs to be ventilated. It is required by code in many places for building contractors to ensure adequate ventilation in bathrooms. They do not always do so.
The easiest way to check if the van is ventilating properly is to take a Kleenex or single square of toilet paper and place it along the fan while it's running. If the fan holds up the paper and keeps it attached, then it's working properly.
Additionally, vents placed near the floor are at a greater risk of being clogged with dust or other debris. This can further restrict airflow and may even create a situation where mold and mildew growth can occur. When vents are placed near the ceiling, air is able to more freely circulate throughout the room.
Fresh air intake vents are simply the way your home takes in fresh outside air, making sure the air inside your home isn't overtaken by contaminated or toxic air. It is an air duct that starts in the space where the furnace is located – usually the basement – that leads to an outside vent.
Because warm air rises, it tends to accumulate near the ceiling in these spaces. To maintain an even temperature throughout the room, return air vents should ideally be positioned higher on the walls or near the ceiling to capture the rising warm air effectively.
Bathroom exhaust fans must be vented through the roof or the side of your house. Plan the location for the bathroom exhaust fan so that the duct has the shortest and most direct route to the roof or wall vent.
To fulfill the local exhaust airflow requirements of ASHRAE 62.2 (2010) and the International Residential Code (IRC 2021, Section M1507), bathroom fans should have a mechanical exhaust capacity of ≥ 50 cfm for intermittent operation or ≥ 20 cfm of ventilation when operated continuously.
The moist air will fuel the growth of mold and mildew on the roof framing and the sheathing that covers the timbers. Wood rot is an absolute certainty over time if you dump bath exhaust into an attic. This moist air must exhaust to the exterior of your home. This is non-negotiable.
Behind or within the Wall: In most cases, the vent pipe for a toilet should run vertically from the toilet's waste pipe (known as the closet bend) and extend upward to connect with the main vent stack or a branch vent line that ultimately exits through the roof of your home.
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.
