How to Ventilate a Bathroom Without Windows
In a home without windows, there are few options for ventilating the bathroom. If you have an exhaust fan in your bathroom, make sure it is vented to the outside of your house and not into another room. This will keep odors from wafting around your house and keep humidity levels down. You can also open a window or door while showering or bathing to allow fresh air into the room.
In this article, we will discuss how to ventilate a bathroom without windows. If you don’t have windows in your bathroom, you can install an exhaust fan. The fan will bring the air out of the building and into the room. This is better than having a fan that sucks air back into your house after heating coils have filtered it. Make sure to open a window or door while taking a shower or a bath to let fresh air into the room.
10 Methods on How to Ventilate a Bathroom Without Windows
1. General Ventilation
One of the most important methods of ventilating a bathroom is using a fan, which will suck out the air from the small room. The first step to do this is to have either an exhaust or intake fan installed. However, you cannot just have any fan installed without taking precautions because it might lead you to spend more time, energy, and money.
2. Using an Exhaust Fan
An exhaust fan is placed on the outside of your bathroom walls or ceiling for it to suck out air from the small room. It draws humid air into itself while pushing fresh air into the room, reducing humidity levels by 30% within minutes. This fan should run for 15 to 20 minutes. They are relatively cheap and inexpensive, but they do have disadvantages.
3. Using an Intake Fan
An intake fan works oppositely as an exhaust fan because it draws humid air from the small room. Intake fans are placed near the bottom of your bathroom walls or floor to bring fresh air into the room.
It draws humid air into itself while pushing out fresh air in the room, which reduces humidity levels by 30% within minutes. This fan should run for 20 to 30 minutes, and they are more expensive than exhaust fans, but they do have their advantages and disadvantages.
4. Using a Ventilation Fan
Ventilation fans are installed in your bathroom ceiling and can be used as both an exhaust fan and an intake fan. To use it as an exhaust fan, make sure to place it opposite the bathroom door or near where air enters the room, which will suck out humid air from the small room. This fan should run for 15 to 20 minutes.
To use it as an intake fan, make sure to place it near where air leaves the room or in a return duct in your bathroom ceiling for it to bring in fresh air into the room. This fan should run for 30 minutes, and they are more expensive than exhaust fans, but they do have their advantages and disadvantages.
5. Using a Window Fan
Window fans can also be utilized if you don’t have an intake fan or an exhaust fan already installed in your bathroom, which is placed over one of your bathroom windows to bring in fresh air through one side while pushing out humid air through the other side. This fan should run for 30 minutes, which is relatively cheap and inexpensive.
6. Open the Windows
If you don’t have an intake or exhaust fan already installed in your bathroom, then open the windows of your room to bring in fresh air into your bathroom while pushing out humid air outside, especially if it’s not raining on that day. This method is relatively cheap and inexpensive, but it does have disadvantages because the wind might affect your bathroom decorations or furniture if they’re not secured to the walls.
7. Leave the Door Open
Another way to ventilate a bathroom without windows is by leaving your bathroom
door open, which will bring in fresh air through the door and push out humid air into the rest of your home. This method is relatively cheap and inexpensive, but it does have disadvantages because you might forget to shut the door and create a draft leading to other problems such as rising energy bills.
8. Using a Dehumidifier
Another method for how to ventilate a bathroom without windows is to use a dehumidifier, which will suck out humid air from your bathroom. This method is relatively cheap and inexpensive, providing that you already have the machine installed in your home beforehand. Still, it does have disadvantages because it might be loud when working.
9. Using an Air Purifier
An air purifier works by using a HEPA filter to absorb odors and moist air from your bathroom. This method is relatively expensive, but it does have its advantages and disadvantages as well.
10. Installing an Air Exchanger System
An air exchanger system is also another way for how to ventilate a bathroom without windows, which involves the circulation of fresh outdoor air into your bathroom and stale indoor air out. This method is more expensive than other methods providing that you already have the machine installed beforehand in your home, but it does have its advantages and disadvantages as well.
3 Tips to Reduce Humidity Level in Your bathroom
As a result of increased air pollution, old or poorly installed or maintained heat exchangers can add more contaminants to the indoor air than they remove, which reduces this method’s effectiveness in reducing humidity levels in your bathroom. To reduce moisture levels in your bathroom without using an air exchanger system, here are three tips you can follow:
1. Insulate exposed exterior soil pipes that are exposed to cold weather. If exposed exterior soil pipes are not insulated, freezing water within these exposed pipes can increase humidity levels in your bathroom. Simply wrapping exposed soil pipes with 6 or 8 inches of insulation can reduce this problem.
2. Use exhaust fans wisely to reduce the level of humidity in your bathroom. Make sure all shower, bathtub, and sink enclosures are tightly sealed so that they don’t leak water vapor into the room when they’re not in use.
3. Reduce the humidity levels in your bathroom by running exhaust fans 2 or 3 minutes after every shower, bathtub, or sink use. This will ensure that the moisture generated during that activity has been exhausted from your bathroom.

Final Thoughts
Ventilating a bathroom is not difficult and can be done in many ways. There are products available to help you ventilate, such as air fresheners or even using your clothes dryer to suck out the odors from your laundry room vents. These will work if you also open up windows for ventilation when possible, but may not always provide enough airflow on their own.
