No, you cannot use dryer vent duct for a bathroom fan. The two types of ductwork are not interchangeable and serve different purposes. Dryer vent duct is made of metal and is used to exhaust hot air and lint from clothes dryers.
Bathroom fans are usually vented through the soffit or roof and require a plastic or metal exhaust duct.
- Disconnect the power to your dryer at the circuit breaker box
- Remove the lint screen from your dryer and set it aside
- Pull your dryer away from the wall so that you can access the vent duct behind it
- Cut a hole in the side of the vent duct using a utility knife
- The hole should be big enough to fit your bathroom fan’s exhaust pipe snugly inside of it
- Insert the exhaust pipe from your bathroom fan into the hole you cut in the vent duct, then use screws or duct tape to secure it in place
- Reconnect the power to your dryer at the circuit breaker box and turn it on
- Test your work by turning on your bathroom fan and making sure that air is being exhausted out through the vent duct

What Kind of Pipe Do You Use to Vent a Bathroom Fan?
There are a few different types of pipe that can be used to vent a bathroom fan. The most common type is PVC, or polyvinyl chloride. PVC is a plastic that is easy to work with and relatively inexpensive.
It is also resistant to corrosion, which makes it a good choice for bathroom applications. Another option is ABS, or acrylonitrile butadiene styrene. ABS is also a plastic, but it is stronger and more durable than PVC.
It is more expensive than PVC, but it may be the better choice for bathrooms in high-humidity areas.
Is It Ok to Use Flex Duct for Bathroom Fan?
No, it is not okay to use flex duct for bathroom fans. There are several reasons for this. First, flex duct is not rated for the high temperatures that are produced by bathroom fans.
Second, flex duct is not fire resistant and could potentially start a fire if it came into contact with any heat source. Third, the flexible nature of flex duct makes it more likely to sag over time, which could block the airflow from the fan and cause it to overheat. Finally, flex duct is not as durable as other types of ductwork and could easily be damaged by moisture or pests.
What Can I Use If I Don’T Have a Bathroom Vent?
If you don’t have a bathroom vent, there are a few things you can do to help improve the air quality in your bathroom. One option is to open a window while you shower to let some of the steam escape. Another option is to use an exhaust fan.
Exhaust fans pull the moist air out of the room and replace it with drier, outside air. If you don’t have an exhaust fan, you can try running a small fan in the bathroom while you shower to help circulate the air and remove some of the moisture.
How Far Can You Run Flex Duct for Bathroom Fan?
Assuming you are referring to residential ductwork, the answer is not very far. Flexible ductwork is not meant for long runs and starts to lose its shape and effectiveness beyond about 15 feet. If you need to run your bathroom fan ductwork more than 15 feet, you should use solid metal ductwork instead.
Difference between Dryer Vent And Bathroom Vent
There are a few key differences between dryer vents and bathroom vents. For one, dryer vents are typically larger in diameter to accommodate the high volume of air that is produced by a clothes dryer. Additionally, dryer vents are made of metal or other durable materials to withstand the heat produced by the appliance.
Bathroom vents, on the other hand, are typically smaller in diameter and made of plastic or other less heat-resistant materials.
Another key difference between these two types of vents is their location. Dryer vents are typically located on the exterior of a home, while bathroom vents are typically located within the interior walls.
This is because dryers produce much more heat and moisture than bathrooms, so it is important to vent them outside to prevent any damage or fire hazards.
Bathroom Vent Duct Size
Bathroom exhaust fans are vital for removing moisture and odors from the home. The size of the vent duct is an important factor in proper operation of the fan.
A small bathroom up to 100 square feet will require a 4″ diameter duct. A medium sized bathroom between 100-200 square feet will need a 5″ diameter vent.
Anything over 200 square feet will require a 6″ diameter vent.
Most homes have pre-existing ductwork that can be used for the installation of a new bathroom exhaust fan. If not, installing new ductwork can be a bit challenging.
It is best to consult with a professional to ensure proper installation and avoid any potential issues down the road.
4” Or 6” Duct for Bathroom Fan
The debate over what size of duct to use for a bathroom fan is one that has been around for years. There are pros and cons to both 4” and 6” ducts, so it ultimately comes down to personal preference. Here is a breakdown of the two options:
4” Duct:
-Easier to install than 6” duct
-Takes up less space in the wall or ceiling cavity
-Lighter and easier to handle than 6” duct
-Cheaper than 6” duct
6” Duct:
Conclusion
If you have ever wondered if you can use dryer vent duct for your bathroom fan, the answer is yes! Dryer vent duct is made of flexible aluminum and is available in a variety of sizes to fit your needs. It is also easy to install and can be done in just a few minutes.
