How to ventilate a bathroom

By properly ventilating every bathroom in your home, you can not only eliminate unwanted odors, but you can also remove troublesome excessive moisture. Because the bathtub and the shower – especially the latter – a bathroom is subjected to a large amount of moisture. This is caused by the steam of a hot shower, for example.

It is also caused by condensation, the foggy mist you can see on your bathroom mirror after bathing. If this water is not removed in a timely manner, health-threatening mold and mildew will result. Excessive moisture and condensation can also cause other problems, such as rotting, in your home’s foundation.

Opening a window in your bathroom is undoubtedly the easiest way to ventilate your bathroom. Even if you just crack a window every time that you take a bath or shower, this will help to circulate the air and eliminate unwanted odors and moisture. Also, you should leave the shower curtain or door open after you bathe. This practice will also help to increase needed air circulation.

If your bathroom does not have an existing window that you can open, you can install one yourself. Or, you can talk to a reputable contractor about putting one in if you don’t want to tackle the project yourself.

According to the experts, your bathroom needs a specific amount of airflow in order to be properly ventilated. Minimally, the air in your bathroom should be changed twelve times an hour.

To figure out the cubic feet per minute (CFM) of air that is needed to ventilate your bathroom, you will need to measure, and then multiply the width of the room by the length by the height. Then, divide that number by five. The result will be the cubit feet per minute of air needed for your bathroom.

The most common way that you can circulate and replace the air in your bathroom is to install and use a ceiling exhaust fan. The advantage of an exhaust fan over a window is that a fan can be used year ’round without compromising your heating and cooling bills. You will need to make sure that the fan you choose is large enough to move the air in your bathroom sufficiently. That is, that the exhaust fan will meet or exceed the estimated CFM of your room.

In choosing a fan, make sure that you purchase a good quality motor. And, make sure that the motor is built to operate efficiently and quietly. Most exhaust fans are readily affordable and fairly easy to install.

Some exhaust fans have other options on them, such as motion detectors, night lights, and timers. Since the experts recommend that an exhaust fan be run for approximately twenty minutes after you leave a bathroom, a timer would be a good idea. A fan can easily fit into the fixture that currently houses the ceiling light in your bathroom.

To vent your exhaust fan to the outdoors, you can easily install a four inch vent that goes through an exterior wall to the outdoors. You can also install the same size of a vent through the attic to the roof to the outdoors too.

Wiring the exhaust fan in your bathroom isn’t really hard, but if you don’t know what you’re doing, then you should hire a licensed electrician for that part of the project.
