Before you start installing a bathroom ceiling fan there are some things you need to remember. You should first know how much room the fan will occupy and whether or not it will fit in the room. Also, you should know about noise levels and ventilation. These factors will help you choose the right fan for your bathroom. Once you have these details, you can calculate the size of the hole in your ceiling.

Installing a Bathroom Ceiling Fan

Inline fan

An inline bathroom fan is a convenient and effective way to increase ventilation. Inline fans are quieter and more efficient than traditional fans. They are also much more powerful that bathroom fans, which is great for bathrooms with long run ducts.

Depending on your design, you can mount inline fans directly to the ceiling. They typically have two ducts: an external one that connects to the roof vent and an internal one. The intake vent will draw air from the ceiling and the other will blow it out of the roof vent.

CFM rating refers to the amount of air that an inline bathroom ceiling fans can move. This is measured per minute in cubic feet. A fan with a CFM rating less than 50 or 80 will work well in a bathroom that is less than 100 feet square. A fan that can move at least 80 CFM is recommended for bathrooms with a jetted tub.


Proper ventilation is crucial from a bathroom ceiling-fan. Bathroom fans were often vented into the attic before the 1970s. However, building codes now require proper venting to the outside. Ventilation problems such as mold and moisture can be caused by improper venting. A bathroom fan should be vented via an operable window in order to avoid such problems.

CFM ratings are important to ensure proper ventilation when choosing a bathroom ceilingfan. Also, make sure to check your local building codes and model code. My roofing company was contacted by a customer who wanted to know if ventilation could be installed in a 12×8 bathroom with an open beam ceiling.

The first step is to measure the ceiling hole and locate the vent fan housing. A reciprocating or drywallsaw are both options. Also, you should wear goggles as well as a respirator. Once you have measured the location, the housing can be fitted between the two joists. Once you have the housing, attach the flexible duct to the elbow attached to the vent fan. Stick the foil duct tape on the duct. Finally, thread the electrical cable through the connector and tighten the screw that will connect the two joists.

Sound Levels

It is important to know the sound level before buying a bathroom ceiling fan. The noise level of a bathroom fan is measured in sones. The fan will be quieter the lower the sones. If you want a fan that won’t disturb you while you’re bathing, consider a 0.3-sone model. It will produce the same sound as a refrigerator’s hum.

Bathroom ceiling fans come with a variety of noise levels and sound effects. These levels can also be measured in sones which are industry standards for sound intensity. In general, bathroom fans produce sounds between 0.3 and 4.0 sones. A refrigerator hum produces a single sone, while an annoying fan produces four.

Bathroom ceiling fans producing a high volume are usually deemed loud. Many people are cautious about turning them on. While this is a valid concern, the noise level of bathroom exhaust fans depends on several factors. For example, noise from a 4.0-sone fan can cause noise disruption in bedrooms and hallways.


To install bathroom ceiling fans in your bathrooms, you can hire a contractor. A contractor may have to add new wiring and ductwork, depending on how big your bathroom is and what type of fan it is. He may also need to access your roof vents and attic. Before you begin, make sure that the drywall and other materials are secure.

While bathroom fans can be installed yourself, it is possible to get professional help if your electrical wiring is not in order. There are electricians available in your area that can help you choose the right fan for your space. They can also advise you on how much CFM and ductwork you will need.

Measure the vent area before you begin installing it. You need to locate the vent fan housing between two joists, close to the reference hole. Consider any nearby obstacles. Once you know where the intake port is located, you can dig a hole. Use a level to help you locate the joist or stud.

Inspect the installation site for any damage that may have occurred during construction. If there is any, make corrections before proceeding with your fan installation.

Bathroom ceiling fans are UL listed and meet all applicable safety requirements in order to protect both consumers and workers.
