The bathroom is a wet room. Therefore, it is an environment conducive to the appearance of mold. In order to maintain clean and healthy walls, it is necessary to adopt the right gestures. Discover all the solutions to remove humidity in a bathroom before calling a professional.
Ventilate the bathroom to avoid humidity
If there is one essential gesture, it is to open the bathroom window every day to ventilate. 10 minutes are enough to renew the air in the room and eliminate humidity, especially after a shower or a bath.
Advice : if your bathroom does not have an opening to the outside, the solution is to create a current of air to avoid humidity. Do not close the door tightly, leave it ajar to let the room breathe as much as possible. And to create permanent ventilation, the trick is to drill a few holes at the bottom of the door, then dress them with a grid in the color of the door.
Ventilate well to remove humidity in a bathroom
Ventilation is as important as aeration. It is therefore advisable to install ventilation to circulate the air in the house. The main model is controlled mechanical ventilation, better known as CMV. In addition, this system proves to be the most effective in removing humidity in a room. The VMC captures the air from the home and rejects it outside.
On the other hand, there is the VMR (distributed mechanical ventilation) which has the advantage of being simple to install. The principle is the same as for the VMC, except that it is triggered automatically when the lamp is turned on.
On the other hand, the VMI (mechanical ventilation by insufflation) has a different system. Fresh air is injected before propelling the stale air out.
Finally, natural ventilation is also an alternative that should not be overlooked. The idea is then to install a low ventilation grille to introduce fresh air and a high grille to expel hot air.
Advice : in a humid room, there is necessarily a manual ventilation or a CMV. But the grates can be dirty. Over time, dust accumulates on the grille and clogs it. To remedy this, disassemble the grille and brush it with soapy water before rinsing and drying it. The hole can be cleaned with a dry cloth, but it is best to use a vacuum cleaner before putting the grille back in place.

Are chemical absorbers effective in removing moisture?
Chemical absorbers are a solution to make a room no longer damp. These processes use the absorbent powers of hydrophilic crystals. These capture moisture before liquefying it.
The only thing you have to do is empty the bin from time to time.
Watertight barriers on bathroom walls
Water attacks the walls of a water feature. To prevent this phenomenon, the origin of humidity and the proliferation of mould, it is advisable to integrate waterproof barriers. There are two methods for this:
- the injection of resin which creates a protective film at the foot of the walls;
- and the injection of silicone, easy to apply and ecological, which makes it possible to combat humidity even when it has already settled in the bathroom.
Remove sources of moisture
To have a healthy room, it is important to hunt for sources of humidity. Check the seals of the bathtub, shower or sink because they can generate small leaks and maintain humidity. Also make sure that your windows are properly sealed so that they do not let in either the water or the cold.
By the way, it is better to forget about the drying rack in the room, whether it is a folding model or hanging from the ceiling. This brings humidity into a confined room. Also remember to regularly change the bathroom linen such as towels and bath sheets, which represent contributions of humidity.
How to improve the insulation of the bathroom?
First, you should know that hot air is a barrier to humidity. However, it is not necessary to overheat the bathroom. It is enough to maintain a pleasant ambient temperature, around 19°C.
Then, it is essential to reduce heat loss. For this, the installation of double-glazed windows is a priority. And to reinforce the insulation of the bathroom and remove humidity, you can use extruded polystyrene panels, which are not afraid of water.
How to dry the air?
In the fall, the use of a heater can avoid humidity problems in the bathroom. The easiest way is to install a towel radiator or, failing that, a small auxiliary heater, checking its compatibility with a humid room.
Before washing, just turn on the heat source and then turn it off a quarter of an hour later, enough time to dry the air.
The right paint to fight humidity
If you are planning renovations in your bathroom, choose an acrylic paint. It contains fungicides, which limits the development of fungi and other moisture-related parasites. The paint is resistant, washable and gilded with an anti-mold and anti-grease protective film.
To note : there are also special humidity paints.
Use a dehumidifier
If none of the previous measures bear fruit or if you cannot carry out work immediately, the solution is to equip yourself with a dehumidifier.
If you do not have such a device, there is another solution. Place a moisture absorber bag in the cabinet where the bath towels are stored.
Call a moisture professional
Adopting the right gestures is not always enough. If the humidity persists, it may be wise to call in a professional. This expert will establish a precise diagnosis to detect the source of humidity in the room. He will also guide you on the most suitable treatment to overcome it and find a healthy bathroom.
