Things to look for in a bathroom dehumidifier
When it comes to choosing the best dehumidifier for a bathroom, there are a few factors that you need to consider that differ from if you were buying one for another area of your home.
- Operational mode: While electrical dehumidifiers are super effective at removing excess moisture from the room fast, some potential safety concerns come with using them in the bathroom. Bathrooms, of course, are wet environments, which means you run the risk of electric shock or short circuits if your dehumidifier gets exposed to water. Even a minor splash could comprise the dehumidifier. Consider opting for a dehumidifier that uses an absorbency method such as gel or beads rather than powered by electricity.
- Size and capacity: Your bathroom is easily the most humid place in your home. However, chances are it is the smallest too. So, the first thing you need to do is determine the size of your bathroom in square footage. This will help you narrow down the dehumidifier capacity you require, as all dehumidifiers have a maximum room size.
Size-wise, if your bathroom is compact, then you don’t want a huge, bulky dehumidifier getting in the way. So make sure you take a close look at the dimensions. If you’re going to opt for an electrical version, then you will need to ensure that it’s big enough to service the entire area surrounding the bathroom, as we would advise placing an electrical appliance within your bathroom, especially when you’re showering or bathing. - Noise: Noise levels vary for dehumidifiers, but one thing is for sure, you don’t want to listen to anything too loud while you’re trying to relax in the bath. Look for dehumidifiers that have a decibel rating under 40, this is especially important if you’re looking for the best dehumidifier for the bedroom too.
- Auto-humidity: Bathrooms never stay in the same humidity because you’re in and out and doing different things. So, if you are going to opt for an electrical version, look for one with an automatic humidity setting. That way, it will kick in when it rises past a set level and stop running when it brings that humidity back down.
Is it safe to use a dehumidifier in a bathroom?
Using a non-electrical dehumidifier in a bathroom is completely safe. If your chosen dehumidifier uses a gel or beads to collect the water, then there is no problem. It’s a great idea because the bathroom is one area where humidity levels are always high, even if you’re not taking a shower. So by using a dehumidifier in the bathroom, you’re reducing the chance that mould and mildew will spread elsewhere in the house.
A non-electrical dehumidifier is the perfect way to reduce humidity in a house, especially in a bathroom – it's also ideal for preventing mould in wardrobes with ease.
Chris Michael, managing director at Meaco, a leading dehumidifier manufacturer, advises, “We don’t advise using a (electrical) dehumidifier in the bathroom because it isn’t IP rated, but positioning a dehumidifier as close to the bathroom as possible with the door open still can help to reduce moisture quickly.”
Electrical dehumidifiers also have cords and plugs not designed to be used in wet environments. Constant exposure to moisture can cause the corn insulation to fray or crack, which could increase the risk of electrical shock. Not to mention, draping cords are a trip hazard.
"Because I don't have the correct IP-rated electrics in place in my bathroom my only option was to seek a dehumidifier that is not mains-powered," says Tamara Kelly, w&h's lifestyle editor. "I decided on the UniBond Moisture Absorber AERO 360º and it does the job perfectly. My bathroom is only small but you'd be amazed at how much moisture the device captures. All you simply do is buy the refills every few months to keep it functioning at all times."

What kind of dehumidifier do I need for a bathroom?
When it comes to choosing the best dehumidifier for a bathroom, you first need to determine the right size. If your bathroom is small, opt for a non-electrical version using silica gel or beads to soak up the moisture. These dehumidifiers are super versatile as they’re small, compact, and can be placed anywhere.
If your bathroom is a little larger or you want to ensure the rest of your home stays within normal humidity levels, then opt for an electrical version. Be sure to purchase a dehumidifier that is the right size for the area.
To do this, measure the square footage of the area and cross-check against the manufacturer's specifications. You can then place the dehumidifier in a central position and leave it to work its magic. Just be sure to leave the bathroom door open when you’ve finished to release the moisture for the dehumidifier to remove.
In general, it’s a great idea to use a dehumidifier for bathrooms because it’s the ideal environment for mould, condensation, and dampness to occur. However, it is advisable to avoid using electrical dehumidifiers within the action room itself. The potential safety hazards associated with their use in these damp environments far outweigh the benefits of moisture removal.
If you do wish to use an electric dehumidifier, then always situate it outside the bathroom itself. You will still reap the benefits, and as a bonus, it will work to remove excess moisture from the surrounding areas, too as well as perform other functions like being able to use a dehumidifier to dry your clothes.
While some bathrooms have adequate ventilation to stop the moisture from causing dampness, mould, and condensation in your bathroom, sometimes they’re just not enough to stop the problem. Likewise, opening up a window is all good until winter kicks in and you’re shivering in the shower. Therefore it's also a good idea to have a solution in place, such as one of the recommended dehumidifiers above.
