Once you've finished your shower or bath, simply get a towel and dry those surfaces which might have gotten wet or have a visible condensation layer. Surfaces with regular moisture build-up tend to be the windows, mirrors and tiles/wall panels. Make sure you prioritise these when drying surfaces.
You really have only two choices; 1: towel down the shower when you are through and remove any wet towels, etc from the room and run the exhaust fan for an hour, or 2: leave the wet towels etc in the bathroom and use a dehumidifier.
Fit an extractor fan
If your bathroom has a window that can't open or doesn't have a window at all then this is a good alternative. A good tip is to leave the fan running with the bathroom door closed at least 15 minutes after your shower or bath to make sure most of the moisture has been extracted.
Use a dehumidifier placed at the highest setting possible to dry the floors. Place it in the center of the room and leave it on for at least 24 hours. Next, place fans around the room so the entire surface receives the blowing air.
Rock Salt. The most popular DIY dehumidifier is the one that works the best—rock salt. Rock salt naturally absorbs moisture out of the air, making it a great choice to use as a dehumidifier.
Purchase a portable dehumidifier
Small, portable dehumidifiers can be placed in the bathroom and used during and after your shower to reduce humidity. These can be used in conjunction with a whole home dehumidifier.
Keeping your shower doors closed at all hours of the day locks in moist air and can lead to mold. After you shower, the interior space is at its wettest point. Try to keep the doors open for a half hour or so until the steam clears. If you have a fan in your bathroom, make sure to turn it on and let the air circulate.
This is because a large amount of moisture is produced when you shower or take a bath, increasing the humidity level in the room. If your bathroom is not well ventilated, humid air will condensate on surfaces and lead to mould growth. Bathrooms contain surfaces that are prone to condensation.
Condensation forms when moisture is released into the air and mixes with water vapour. Once this makes contact with cold surfaces, the droplets form on areas such as mirrors and windows. After a shower or bath, water droplets form on the window, walls and mirror when the warm, damp air is cooled by these cold surfaces.
Try to take cooler showers when you can, and keep the door open to the bathroom when you can to increase the air circulation. Another effective way to dehumidify your home naturally is by turning on the bathroom's exhaust fan every time you take a shower.
DampRid crystals work immediately to absorb excess moisture from the air. The crystals harden and form a solid mass. Then they begin to dissolve and liquid will begin to drip into the bottom chamber. It may take a few days before liquid begins to drip.
To let moisture escape, leave your bathroom window open during showering and for at least 15 minutes after. If your bathroom doesn't have any windows, leave the door open instead. Some plants, including spider plants and snake plants, can also help remove moisture from the air.
Keep windows open after showering to dry your wet room, and install an extractor fan if you don't already have one. Another way to keep your wet room floors dry and prevent slipping is to use a dry mop to soak up any excess water after showering.
Bathroom waterproofing with liquid membranes is perhaps the easiest and cheapest modern method of waterproofing, which can be applied to any surfaces that come into contact with water or moisture.
Open a window
Opening a window is the easiest solution to allow the humid air to escape, replacing it with fresh, dry air instead. It's a good idea to do this before taking your bath or shower, as the condensation can escape straight away rather than lingering in the room.
Baking Soda: Baking soda is cheap and easy to find. It's great for small areas and helps neutralize odors while absorbing moisture. Use it in closets or cabinets.
Apply baking soda
The longer you let the soda sit, the better. At an absolute minimum it should be left for 30 minutes. By doing this, the baking soda will absorb the moisture and odours embedded in the mattress.
Plants are natural dehumidifiers because they absorb water from their surroundings through their leaves and release moisture back out through transpiration. This process helps regulate humidity levels and create fresh air in any space! And some plants are better than others.
