An exhaust fan is the most workable method to remove moisture from the air. It is best for a bathroom without a window. With fan technology, exhaust fans pull the excess moisture out of the air.

It will also help remove moist odors, help remove mirror fog, and remove rust on metal surfaces in your bathroom without a window. Exhaust fans will require an installation expert, but they will most effectively remove moisture from the air once installed.

When moisture is removed, it will not allow mold to grow and harm the things in the bathroom. Additionally, you can also place portable fans to keep the bathroom fresh.

2. Use a Dehumidifier

Will a dehumidifier work in a windowless bathroom? Yes, a dehumidifier will do the job. But How? It can remove the excess moisture in a bathroom without windows that do not have an exhaust fan installed.

Reducing humidity levels in the bathroom is a great idea for proper air circulation and better air quality.

A good humidifier will pull moist air from the area and blow dry air into the room to avoid breathing problems. Although humidifiers are expensive, they do the trick.

3. Wipe Down the Walls

Water droplets come onto your walls after a hot shower. With time, they will evaporate into the air, causing an increase in moisture and, therefore, mold growth.

Simply wiping down the moisture off the walls can be very beneficial for removing the musty smell. It is a long and wearing-out process, but it always pays off.

4. Invest in an Air Purifier

Air purifiers are suitable for any room, especially for bathrooms. They help circulate air around, which decreases excess moisture buildup.

An air purifier with an activated carbon filter also helps eliminate foul odors, especially in the windowless bathroom, where odors from the shower, bath, and toilet can linger.

Furthermore, air purifiers can improve indoor air quality by capturing tiny mold particles that might be in the bathroom if you don’t clean the floor regularly.

5. Use an Air Conditioner

Using an air conditioner is also a great idea to solve bathroom ventilation issues. They draw in air through the bathroom vent and cool it before releasing the cooled air back into the room.

It helps to get rid of moisture from the air inside the bathroom. The air conditioners also help remove heat from the air and keep the bathroom cool. Air conditioning helps to prevent mold and mildew growth.

6. Open Bathroom Door

Opening the bathroom door helps the air circulate better. Moisture gets dispersed out of the bathroom quickly, and fresh air enters the room.

Having fresh air entering the bathroom will help disperse the moisture. If your home is too humid, opening windows near the bathroom may help reduce excess moisture in your air.

7. Use a Ceiling Fan

Another method to help ventilate a windowless bathroom is using a ceiling fan. A ceiling fan will not help get rid of moisture from the air but it will still help to keep the bathroom ventilated by air circulation.

A ceiling fan is an excellent tool to help ventilate a windowless bathroom, even if the bathroom is not damp or muggy. A ceiling fan will not absorb moisture from the air, but it will still help ventilate the bathroom by circulating the air.

Also, putting damp towels in the bathroom is not a good idea. It will cause mold and bacteria to grow on it, which can spread to other areas of your home. So, make sure you dry your towels after every use.

Frequently Asked Questions

How long should I keep the bathroom fan on after the shower?

If you have a bathroom fan, it is always good to leave it on for at least 20 to 30 minutes after you shower. This will allow the air circulating in your bathroom to dry out completely.

This way, there won’t be any mold or mildew growing in your bathroom, and you will be able to enjoy the nice cool air that comes from the fan.

Are bathrooms without windows OK?

Bathrooms without windows are OK if you have a well-ventilated bathroom and do not expect the bathroom to be used often.

However, the bathrooms should have at least one window, even if small. This will allow some light in during the day and make it easier for people to see what they are doing there.

Why Does a bathroom vent need to be vented outside?

A bathroom vent needs to be vented outside because it is a cold air return. It means that the warm air inside the house will be sent back out through the chimney or flue and circulated throughout the home. It will also help keep humidity levels down in your bathroom.

Conclusion 

It’s likely that simply using one method won’t prove too effective, especially if you are a fan of everyday hot showers.

If that’s the case, you’ll have to mix and match and try multiple methods in conjunction. For example, try using an exhaust fan while making sure not to leave spills unattended. Try keeping the bathroom door open too.

Always try to ventilate your bathroom; it is dangerous to breathe in the moist air of your bathroom.
