Nowadays, bathrooms and toilets are usually enclosed within the main house. This has led to much speculation, even among scientists, about whether the doors should be closed or left open when not in use.
Firstly, to understand whether it is better to close or leave open, it is necessary to understand the characteristics of the bathroom. Bathrooms are usually damp and, especially if they include a toilet, can harbor a lot of bacteria. The constant moisture also leads to mold in the bathroom. Therefore, when the main door is left open, the damp bacteria from inside the bathroom will spread to other areas of the house.
The expert opinion is that
It is advisable to close the main door of the bathroom to prevent damp bacteria and mold from spreading through the main door to the rest of the house. However, it is recommended to open the bathroom window or use a ventilation fan to maintain air circulation and prevent stuffiness, while also helping to keep the bathroom dry and well-ventilated.
Opening the main door of the bathroom may also allow unpleasant odors from the bathroom to spread to other rooms in the house, causing discomfort. This can also lead to additional health issues for other family members, especially for those susceptible to digestive diseases. There are numerous bacteria that are not visible to the naked eye but are concentrated in the bathroom. Therefore, if you don’t close the door, these bacteria will spread throughout the house, polluting the air. Many households have the bathroom facing the kitchen, which further affects the overall hygiene of the house.
Moreover, during the summer, if the family is using air conditioning in other rooms, closing the bathroom door will prevent the cool air from escaping into the bathroom.
To keep the bathroom well-ventilated and clean
Many bathrooms do not have windows or exhaust fans, so people tend to leave the main door open when the bathroom is not in use to let it dry. However, this is not recommended as it is much safer to have windows or exhaust fans for ventilation. Furthermore, opening the windows and turning on the fan not only helps with ventilation and odor control while you are taking a shower, but also keeps the air fresh and clean inside the house.
Therefore, it is best to modify the bathroom design and add a window or exhaust fan before closing the main door when the bathroom is not in use.
In addition, avoid drying wet clothes or towels in the bathroom. It is also important to keep the bathroom clutter-free.
Use a lidded trash can in the bathroom to prevent the spread of bacteria and make sure to clean it regularly.
