Small bathrooms are even more difficult to work with than other bathrooms because they tend to get extremely humid. In a small environment, running the shower just for 10 minutes can create a whole lot of steam and humidity. \
Moist, humid air can cause mold to grow and create moisture buildup that leads to ceiling discoloration. This means that managing moisture and keeping the bathroom dry is essential. \
Fortunately, there are multiple ways to do this. A strong bathroom exhaust fan works wonders to keep the room dry and remove moisture from the air. \
A fan works best, but any ventilation will help keep the bathroom dryer. If there is a window, crack it open slightly when you take a shower and leave it this way for a few minutes afterward. \
Also, don't close the bathroom door tightly and then take a shower. Leave it open whenever you can, and open it just a crack when you need privacy. \
You can also simply place a fan of any kind in the bathroom. If there is no ceiling fan, try a small table fan or a standing fan. \
The moving air will help dry everything off and provide ventilation. Any kind of moving air is helpful for keeping spaces dry. \
A dehumidifier is literally made to remove humidity from the air, so of course, this will work extremely well to keep the space dry. However, these little machines can be somewhat expensive, so you can always try more affordable alternatives if needed. \
Hanging moisture absorbers are designed to remove moisture from the air, and they are much more affordable than dehumidifiers. \
If you're looking for a more DIY solution, just get ahold of some rock salt. This stuff acts as a natural dehumidifier, and it's pretty affordable, especially when compared to your other options. \
