Proper ventilation in bathrooms is essential for a healthy environment. Ventilation can be placed in two ways either by windows or by mechanical devices like exhaust fans. Windows may not be suitable at all time, but with the help of exhaust fans balanced atmosphere can be maintained by reducing the formation of unwanted odors and moist air in the bathroom. In order to throw out moist and dust air, an external vent on outside is provided. Varieties of exhaust fans are now available in the market. The model ranges from simple to large having timer switches and lights. Some are designed in order to mount on walls and others on ceiling. So, let’s look at the process for installing the exhaust fan in your bathroom.
Complexity Level: Moderate
Time Required: 2-3 hours
- Wire strippers
- Electrical tester
- Jig saw
- Exhaust fan unit

- Dryer vent clamps
1. Determine the model and area you need for installation
Varieties of exhaust fans are available now. There are fans which have allergen reducing filters, lights, timer switches etc. Some fans can be fixed only on ceiling and some others on walls. A good exhaust fan has the warranty of minimum 6 months. An area that offers proper rout for venting should be selected.
2. Wiring options required for exhaust fan
- After the completion of installation, wiring should be done.
- If wiring is already there, then it’s well and good. In this installation process, both light and fan will run at same time.
- If separate switch is needed for performing the functioning of fan and light, a three wire cable is needed in order to join the device and existing switch with each other.
- Additional cable wires are essential for units having lights and heaters.
3. Proper care should be taken in installation process
- Unit should be installed only after making sure that all power panels are switched off.
- The area where you need to mount the unit should be properly examined. If there is any insulation, remove it.
4. Venting of the exhaust fan
While installation, venting is an important part to be considered. Improper venting may cause formation of condensation within it. This condensation creates a leakage around the unit and it affects the surroundings. In order to avoid this, don’t transfer moisture directly to the attic. Roof vent can be prevented while venting through nearest soffit. It can be connected by using plastic ducts which are flexible. Condense formation can also be avoided by insulation wrap.
