Best Bathroom Dehumidifier (2020 Reviews)

People buy dehumidifiers for a variety of different reasons, the most common of which is to reduce humidity. One common place where a lot of people need dehumidifiers is the bathroom. Buying a dehumidifier for the bathroom is something that can not only prevent the spread of mold and mildew in the bathroom itself, but can also indirectly affect the humidity in the rest of your home, since the bathroom’s moisture often affects the humidity levels in other rooms as well.

The great thing about small dehumidifiers is precisely the fact that you can move them around and use them for multiple different purposes. The bathroom, however, is one place where not all small dehumidifiers work too well. That’s because the bathroom is quite different than other rooms in the house.

For starters, the humidity levels in the bathroom are significantly higher than they are in any other room. Particularly for big families where this room is used regularly for several activities, including bathing and using the shower, the humidity present can easily reach undesirable levels due to the abundance of steam. And this is something that not every dehumidifier for bathroom use can deal with in an efficient manner.

Another point that is specific to wet rooms is that a dehumidifier for a bathroom needs to be resistant to water splashes and getting slightly wet. There are a lot of great portable dehumidifier models that can easily get irreparably damaged by a random splash of water, thanks to their design. So, picking up a dehumidifier for your bathroom involves considering not only its power level, but its overall design as well.

The size of the appliance is something that’s also very important for this type of dehumidifier – bathrooms are generally not the biggest rooms in the house and you can’t just ignore the size of the appliance like you could with a dehumidifier for the basement, the garage or even the living room.

There are, of course, a myriad of other choices and considerations that need to be kept in mind, but they are in play with every dehumidifying appliance, regardless of where you want to locate it – the brand, the overall quality, any additional features, and so on.

But, to jump from the theoretical to the more practical side of things, below we have compiled a review of the top 5 bathroom dehumidifiers that we could get our hands on, which are available right now. These are not the only models suitable for a wet room – but these are the 5 products we’d suggest as an answer to any general question about bathroom dehumidifiers. Give them a look and maybe one of them will catch your eye:

Our Recommendations

​Winner: ​​SEAVON Small Bathroom Dehumidifier

​It won’t come as a surprise to anyone that is at least a bit familiar with dehumidifiers, that SEAVON make an appearance on our list. Their small bathroom model is excellent in areas of up to 110 square feet and pumps up to 9 ounces or 250 ml of moisture from the air in the span of every 24 hours. 

The capacity of its water container is 16 ounces or 500 ml, so you will need to remove and empty the tank about once every 2 days. Fortunately, this model also has an auto shutoff function that goes into effect once the water tank is full, so there is no risk of overflowing.

Thanks to the thermoelectric peltier module technology that this model also utilizes, as well as its energy efficient 25W ETL certified adapter, this is a very quiet model that won’t disturb your visits to the bathroom, nor your day-to-day life or sleep should you choose to use it outside of the bathroom as well.

  • Energy efficient dehumidifier

  • ​Average water tank capacity, suitable for smaller rooms

​​​Runner-Up: ​Vremi Energy Star Mini Dehumidifier

​​​Securing second place as our runner-up, we have a Vremi dehumidifier which features an exceptional 30 pint water tank. This model successfully removes up to 30 pints of moisture from the air every day, making it very effective for any small to medium sized room, including wet rooms. ​

This dehumidifier is slightly larger than the other units we have reviewed, but we think it makes the perfect choice if your bathroom is consistently wet and humid or you simply have a larger bathroom. The benefits are that it will extract moisture from the air so much quicker than a smaller unit, allowing it to run for a shorter amount of time.

​This Vremi model is very easy to operate and handle, as well as to move around when you need to. ​Its efficient, quiet and powerful - so whether you suffer from excess humidity in your shower room or simply want your towels to dry a little faster, this model is for you.

  • ​Very powerful
  • ​Perfect for any small to medium sized space
  • Might be overkill for very small bathrooms

​​​​Pro Breeze Electric Dehumidifier

​Next up is this Pro Breeze mini dehumidifier. You may be wary towards its size and power level, but this model by Pro Breeze is great for small areas like bathrooms, wardrobe rooms, cabinets and other small spaces with poor ventilation but high humidity levels. 

It works great in areas that are anywhere up to 110 square feet or 20 square meters in size. This model also uses the ultra-quiet whisper technology and thermo-electric cooling (meaning that there is no compressor), which makes it great even for a small bedroom, since it is exceptionally quiet.

It is a very easy to operate machine that also has the auto shutoff option for when its water tank is full, as well as an indicator light that warns you when this is about to happen. With dimensions of 24 x 14.2 x 12.4 cm and a weight of under a kilogram, you can easily place and position this appliance anywhere you want and just let it work.

​​​​​​Ivation IVADM35 Small Dehumidifier

​Progressing down this list we have this Ivation unit that also utilizes the thermo-electric peltier module technology. This compact yet powerful dehumidifier removes up to 20 ounces of moisture from the air per 24 hours of operation. It reaches its optimal efficiency at a temperature of approximately 86°F (30°C) and a relative humidity level of ~80%. The capacity of this model’s water tank is 68 ounces, which means that you will need to remove it and empty it about once every 3 days.

This unit ​is slightly larger than other units on test with its dimensions of 14.1 x 7.2 x 9.6 inches as well as its medium weight of 6.85 pounds. However, thanks to the lack of any moving parts, it is exceptionally quiet and won’t bother you either in your shower room, nor elsewhere in your home, should you choose to use it in different rooms as well.​

​​​Eva-Dry Edv-1100 Electric Petite Dehumidifier

​​​​Finally we have this Eva Dry portable mini dehumidifier. It has a very classical design and also uses the Thermo-electric Peltier module mechanism instead of a compressor. This model includes a water tank that has a capacity of 8 ounces. A LED indicator lets you know when the water tank is full and the dehumidifier shuts off automatically to prevent any accidents. 

This is a small and compact device with its dimensions of 8.6 x 11.8 x 6.5 inches, but it successfully eliminates any musty odor, bacteria, fungus, moisture, and damp patches that can form in your bathroom, as well as prevent mold or mildew from forming in the first place.

​Just as with the other models we have tested, this model is very quiet​ as there is no internal compressor present due to the type of technology (thermo electric) used. ​

The appliance uses no chemical substances, which not only makes it environmentally friendly, but is also quite important for a bathroom, where chemical odors and spillage can be unpleasant.

​How To Choose The Best Bathroom Dehumidifier

Bathroom extractor fans do a great job of removing excess moisture from your bathroom - but the problem is that they usually only run when the lights are on. Likewise, opening a window to assist in dehumidifying isn't always an option if you live in a colder climate or during winter.  

For this reason, we recommend the use of a bathroom dehumidifier to remove the excess moisture that is always present after a hot bath or shower. Doing so will help your towels to dry faster and make your bathroom environment much more pleasant as well as assist in preventing bathroom mold through the removal of excess humidity. Simply put, better air quality for your home.

This buying guide will help you to find the perfect bathroom dehumidifier for the job - simply review each section for a better understanding of what you're looking for. Alternatively, you can find out more about how dehumidifiers work.

Size (Square Feet)

Most small dehumidifiers are capable of operating in an area roughly 110 square feet (1200 cubic feet) in size. If your shower room is considerably larger, we recommend buying a slightly larger model such as the Vremi we recommended above which will cope with the additional air volume. Remember that your bathroom extractor fan will always be assisting in dehumidification and moisture removal whenever it is running. 


Bathroom dehumidifiers are smaller than other types of dehumidifier as your bathroom is usually one of the smallest rooms in your home. 

​Because of this, they're also cheaper than large, full size models and can often be purchased for less than $100. The cheaper the model, the less features it will contain so bear this in mind as you choose between performance and cost.

As mentioned, larger bathrooms and those which are constantly in use will usually require a bigger dehumidifier with a greater capacity which are priced at around the $200 point. If you want humidity control capability, you will also have to purchase a larger model. 

Noise Output

Due to their smaller size, these models are much quieter in operation than your average full-size model. They are not silent, but they should not disturb you if you choose to leave them running whilst you're using your bathroom.

​As a rough guide, we would say that most of these machines ​are no louder than a small space heater or a fan running on a slow speed setting. As we've mentioned, this low noise level makes these models the ideal choice for smaller rooms such as closets or en suite​ bathrooms​ as well as very small bedrooms.

Power Consumption

​Every compact dehumidifier utilizes energy-efficient thermoelectric technology. This is great news for consumers as a thermoelectric dehumidifier is perfect for small spaces such as a bathroom.

​The duration that you will need to run your dehumidifier will depend upon the size of your bathroom and the level of relative humidity.

​For this reason, it is important that you buy an energy efficient (energy star) model which will keep your energy bills low. All of the wet room dehumidifiers ​that we have tested have a low demand for power, but anything ​with an upper limit of around 200w energy consumption will be fine. It is also important to note that more powerful models will be able to dehumidify your bathroom faster.

Water Reservoir Capacity

Each of these dehumidification appliances is designed to collect and store the water that they remove from the atmosphere. The amount of water that can be collected before the reservoir requires emptying will depend upon the overall size of the dehumidifier.

If your bathroom is particularly humid and is full of condensation, we would suggest buying a model with a larger water tank to avoid having to empty it throughout the day.
