Why You Need Ventilation in Your Bathroom

The bathroom sees a fair amount of activity during the day. The obvious uses are of course using the toilet and taking a shower or bath. These two daily activities can be quite wearing on your bathroom walls and your home. A proper ventilation system will not only save your home’s structure, but it will help eliminate any excess gases in the air—of the humid and odorous type.  

What You Need to Know About Ventilation

A bathroom ventilation system is important, no matter your bathroom size. It’s a myth that larger bathrooms don’t need a ventilation system. Just because your bathroom has square footage, doesn’t mean that the gases in the air are evaporating or leaving the room any faster in comparison to a smaller bathroom!


Every bathroom needs a ventilation system that is appropriate to its size. Our HVAC experts are trained to give you advice and install a ventilation system that has the right CFM for your room—that’s cubic feet per minute—so that air is ventilated out at the necessary speed. An HVAC expert will also check the sones on a ventilation fan, which refers to the level of sound the fan emits. The lower the sones, the quieter the fan is when it is turned on.


There are also a variety of ventilation fans to choose from, some with just the basic features of venting air out, but some with features such as an added light or night-light. This works well for smaller bathrooms that need a multipurpose system. In bathrooms that are larger, they are also fans that have a combined heating and light system. This is perfect for keeping you warm after a shower and providing extra lighting for your bathroom needs.

Where Does the Ventilation System Go?

An HVAC expert will take a look at your bathroom and house structure to determine where your ventilation system should be installed and where it should vent. Someone who is doing the job without the experience, may end of venting the system into an attic, which is ineffective and can do more damage than good. At Applewood Air, we make sure to install your ventilation system to the outdoors, using the shortest distance possible between the fan and the outdoors to maximize the airflow. The ventilation fan will need to be installed in the ceiling because humid air and odours will naturally rise to the highest point of the room—making them easier to vent out.


Ideally, the ventilation system should be nearest the place that has the most humidity and moisture emitted, which of course is the shower or bathtub. If it can’t be placed here for reasons like electrical work, it is recommended to place the ventilation system as close as possible, or even near the toilet. An HVAC expert can help you decide the placement of the ventilation fan for the best results.


Knowing When It’s Time To Get One


If you don’t already have a ventilation system in your bathroom, now is the time to get one.


Without a fan and ventilation, your bathroom is especially prone to moisture build up, leading to mildew and mold. Save yourself the cost of mold and mildew removal from the walls of your bathroom by contacting our Applewood Air HVAC experts.  We are happy to take a look at your bathroom and provide ventilation systems based on our observations.
