Choosing The Best Small Bathroom Dehumidifier

People buy dehumidifiers for a lot of different reasons and for ​several different environments. One popular place where a lot of people need dehumidifiers is the bathroom. Getting a dehumidifier for the bathroom is something that can not only prevent the spread of mold and mildew in the bathroom, 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 the bathroom is used regularly for a lot of things, including for bathing, the humidity there can easily reach unfortunate and unwanted levels. And this is something that not every dehumidifier for bathroom use can deal with in an efficient manner.

Another point that is specific to bathrooms is that a dehumidifier for a bathroom needs to be resistant to water splashes. 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 device is something that’s also extra important for a bathroom dehumidifier – bathrooms are generally not the biggest rooms in the house and you can’t just ignore the size of the dehumidifier like you could with a model 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 dehumidifier, regardless of where you want to put it – the brand, the overall quality, the extra features, and so on.

But, to jump from the theoretic to the more practical side of things, below we have compiled a quick list 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 bathroom – 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: ​​hOmeLabs Small Dehumidifier

​It won’t come as a surprise to anyone that is at least a bit familiar with dehumidifiers, that hOmeLabs make an appearance on our list as well. Their small bathroom model is excellent in areas of up to 150 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 tank is 16 ounces or 500 ml, so you will need to remove and empty it about once every 2 days. Fortunately, this dehumidifier 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.

Of course, this HODGSON isn’t just cool looking – it is very easy to operate and handle, as well as to move around when you need to. Its dimensions are 6.4 x 4.2 x 10.2 inches and its weight is just under a kilogram. With these dimensions you probably wouldn’t expect a lot of power, but this model surprises with its effectiveness.

It works great in areas that are anywhere up to 108 square feet or 20 square meters in size. This dehumidifier 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 dehumidifier anywhere you want and just let it work.

​​​​​​Ivation IVADM35 Dehumidifier

​Progressing down this list we have this Ivation model 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 model ​is slightly larger than other models 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 the bathroom, 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 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 odor, bacteria, fungus, moisture, and damp patches that can form in your bathroom, as well as prevent any mold or mildew from forming in the first place.

The dehumidifier 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 extra unpleasant.

  • Thermo-electric peltier module mechanism
  • Effective for its size
  • ​Limited by its capacity


So, these are our top 5 suggestions. Do any of them look like they will fit well in your bathroom? If we had to choose, we’d go with the hOmeLabs model, as it impresses with its impressive energy efficiency and its quality.

The other 4 options also have their great advantages, however, and if they fit your situation better, you’d certainly not go wrong with any of them. Some homeowners might even be better off with a larger 30 pint dehumidifier if they own a home with a sizeable bathroom.
