Why Do You Need to Ventilate a Bathroom?

Bathrooms need ventilation like kitchens and laundries. They do not have windows and can quickly accumulate harmful gases and odors, which can be extremely dangerous to those in the room. 

Not only that, if a bathroom is not properly vented, it will reduce its effectiveness as a shower or steam room.

A bathroom without ventilation doesn’t only smell bad but is very dangerous. In a kitchen, sometimes fumes can get pushed into the rest of your house, and that’s not good for anybody. 

However, two very dangerous chemicals don’t need any ventilation; formaldehyde and ammonia are both used in toilet bowls, so it will be safer to keep the air moving out of your room.

The bathroom exhaust fan removes hot, moist air from the room so it can be replaced with cool, dry outside air. In addition to removing moisture and heat, ventilation also removes potentially harmful chemical compounds such as carbon dioxide, ozone, and nitrogen oxides from the bathroom air. 

A ventless bathroom just recycles the same old air which odors, moisture, and pollutants have contaminated.

Some of you may be thinking, “well, what about on a cold winter day?”. On a cold winter day, the bathroom exhaust fan helps the room warm up faster. This is because it replaces old, cold air with new hot air. And this doesn’t just work for bathrooms; all rooms in your house need an exhaust fan.

Small bathroom ventilation ideas

Small bathroom ventilation ideas are probably something you never thought about until now. Clean air starts with good ventilation, but you can still have a beautiful room to bathe in without it. 

You might want to make your bathroom completely acoustically dampened if the sound is an issue for you. After all, many bathrooms are used as bedrooms in some cases.

This idea is for a room with a window. If you have no access to an outside wall, it might be impossible to use this option. 

First, open your window during the day for a few hours at a time when you can. A little air won’t hurt anything in most cases, and opening the window allows fresh air, which will help dilute whatever is in there. 

After a few hours, at least open it again, and then shut the window and tape over the outside with some plastic or something to keep rain from coming in. There are some other ideas. They are-

• Install a window where possible
• Use electric heater 
• Install a bathroom extractor fan
• Use dehumidifier
• Install a screened shower

How to Ventilate a Bathroom without Windows?

Many bathrooms lack windows. It’s just not possible to accommodate them all, so this leaves the problem of ventilation without proper airflow. So, you can follow the ways that will help you to ventilate your bathroom without windows. 

Step 1: Bathroom fans are one option if your bathroom doesn’t have a window or an outside vent. A fan installed in the bathroom ceiling will pull moist air out of the room and exhaust it through the roof.

Step 2: If the bathroom is centrally located with windows on two walls, you can open both windows partially when the bath is in use and leave them open until the room air feels dry or you can buy an exhaust fan to help speed up this process. With both windows opened slightly, enough air will move through the room to allow the moist air to escape.

Step 3: If the bathroom has only one window, open the window just slightly, about an inch or two, when using the bath and close it as soon as you are done. This will allow enough air to replace the warm, moist air that leaves with it.

Step 4: A fan can be used during the bath, as well as afterward. The bathroom should have a fan that is vented to the outside of your home. This pulls moist air out as it comes off the body and out through the roof.

Step 5: Install an energy-efficient electric heater in the bathroom if there is no warmer place for you to bathe. This will help dry the room quickly.

Step 6: If there is no window, there will be no cross ventilation to pull the moist air out of the bathroom. A dehumidifier can help dry out the room after you’ve used it; running it for an hour or two after your shower should do the trick.

Step 7: Install an exhaust fan in the bathroom. An exhaust fan is the same kind of fan that you would find in your kitchen or any other room in your house. They work almost the same way except they are vented to the outside of your house rather than to an inside wall.
