Bathrooms are prone to moisture and humidity, which can lead to mold and mildew growth. A properly functioning exhaust fan is essential for removing excess moisture and maintaining a healthy indoor environment. If your bathroom’s exhaust fan is struggling to keep up, it may be time to replace it with a larger model.
This guide will provide you with all the information you need to safely and effectively replace your bathroom exhaust fan with a larger one.
Replacing a bathroom exhaust fan may seem like a daunting task, but it is actually a relatively simple project that can be completed in a few hours. By following the steps Artikeld in this guide, you can ensure that your new exhaust fan is installed correctly and operating efficiently.
Safety Considerations
When replacing an exhaust fan, electrical safety is paramount. Before starting any work, turn off the power to the fan at the circuit breaker. This ensures that there is no live electricity flowing through the fan or its wiring, preventing any potential shocks or accidents.
Testing the Circuit
To verify that the power is indeed off, use a non-contact voltage tester. This device can detect the presence of electricity without making contact with any wires. Hold the tester near the fan’s wires and if it lights up or beeps, there is still power present.
Repeat this process at the circuit breaker to ensure that the power has been successfully turned off.
Choosing the Right Fan
When selecting a new bathroom exhaust fan, there are several types available to choose from. Each type has its own advantages and disadvantages, so it’s important to understand the differences before making a purchase.
The most common type of bathroom exhaust fan is the ceiling-mounted fan. These fans are installed in the ceiling and are typically vented to the outside of the house. Ceiling-mounted fans are relatively easy to install and are available in a variety of sizes and styles.
Another type of bathroom exhaust fan is the wall-mounted fan. These fans are installed on the wall and are vented to the outside of the house. Wall-mounted fans are typically smaller than ceiling-mounted fans and are less visible.
A third type of bathroom exhaust fan is the inline fan. These fans are installed in the ductwork of the bathroom exhaust system. Inline fans are typically more powerful than ceiling-mounted or wall-mounted fans and can be used to ventilate larger bathrooms.
When choosing a new bathroom exhaust fan, there are several factors to consider, including the CFM rating, the noise level, and the energy efficiency.
CFM Rating
The CFM rating of a bathroom exhaust fan measures the amount of air that the fan can move in one minute. The higher the CFM rating, the more powerful the fan.
The CFM rating that you need for your bathroom will depend on the size of the bathroom and the number of people who use it. A general rule of thumb is to choose a fan with a CFM rating that is equal to or greater than the square footage of the bathroom.
Noise Level
The noise level of a bathroom exhaust fan is measured in sones. The lower the sone rating, the quieter the fan.
If you are looking for a quiet bathroom exhaust fan, choose a fan with a sone rating of 2.0 or less.
Energy Efficiency
The energy efficiency of a bathroom exhaust fan is measured in cubic feet per minute per watt (CFM/W). The higher the CFM/W rating, the more energy efficient the fan.
If you are looking for an energy-efficient bathroom exhaust fan, choose a fan with a CFM/W rating of 1.0 or higher.

Removing the Old Fan
To remove the old exhaust fan, follow these steps:
Disconnecting the Electrical Wires
- Turn off the power to the fan at the circuit breaker or fuse box.
- Remove the cover plate from the fan.
- Disconnect the electrical wires from the fan motor.
Removing the Fan Housing
- Unscrew the screws that hold the fan housing in place.
- Carefully remove the fan housing from the ceiling or wall.
Patching Holes
- If there are any holes in the ceiling or wall, patch them with spackling paste or caulk.
- Allow the patch to dry completely before painting.
Installing the New Fan
Once you have removed the old fan, it’s time to install the new one. This process is relatively straightforward, but there are a few things you need to keep in mind.
First, you need to make sure that the new fan is the right size for the opening. The fan should be slightly smaller than the opening so that it can be easily installed.
Next, you need to connect the electrical wires. The new fan will come with two wires, a black wire and a white wire. The black wire should be connected to the black wire in the ceiling, and the white wire should be connected to the white wire in the ceiling.
Once the electrical wires are connected, you can mount the fan housing. The fan housing will come with a few screws that you can use to secure it to the ceiling.
Finally, you need to seal the fan housing to prevent air leaks. You can do this by using a caulk gun to apply a bead of caulk around the edges of the fan housing.
Connecting the Electrical Wires
When connecting the electrical wires, it is important to make sure that the wires are properly secured. You can do this by using wire nuts or electrical tape.
Wire nuts are small plastic caps that are used to connect two or more wires together. To use a wire nut, simply twist the wires together and then screw the wire nut over the wires.
Electrical tape is a type of adhesive tape that is used to insulate electrical wires. To use electrical tape, simply wrap the tape around the wires.
Mounting the Fan Housing
When mounting the fan housing, it is important to make sure that the fan is level. You can do this by using a level.
Once the fan is level, you can secure it to the ceiling using the screws that came with the fan.
Sealing the Fan Housing
When sealing the fan housing, it is important to use a caulk that is specifically designed for sealing air leaks.
To apply the caulk, simply use a caulk gun to apply a bead of caulk around the edges of the fan housing.
Testing the Fan
After installing the new exhaust fan, it’s crucial to test it to ensure it’s working correctly. This involves turning on the fan and checking for proper airflow.
Turning on the Fan
- Turn on the bathroom light switch, which should power the fan.
- If the fan has a separate switch, flip it to the “on” position.
Checking Airflow
- Place a piece of tissue paper near the fan’s exhaust vent.
- The tissue paper should be drawn towards the vent, indicating airflow.
- Check the airflow at different points along the vent to ensure even distribution.
Troubleshooting
If the fan is not working properly, check the following:
- Power: Ensure the fan is connected to a power source and that the circuit breaker or fuse is not tripped.
- Wiring: Inspect the wiring connections to make sure they are secure and not damaged.
