The Takeaway:

1. Our Pick: Gurin Mini Thermo Dehumidifier

2. Runner-Up: Eva-Dry Petite Dehumidifier

3. Also Great: Pictek Small Dehumidifier

Bathrooms are an obvious place where you might need a dehumidifier.

After a shower, it can sometimes take hours for the dampness to fade entirely from the air. This, of course, makes the perfect breeding ground for mold and bacteria.

If you don’t do something about it, your bathroom can turn into an unhealthy environment or become a problem that you’ll have to spend big bucks fixing later on. Then, a small dehumidifier for bathroom use is an inexpensive way to nip this problem in the bud. 

What to Look for Best Mini Dehumidifier for Bathroom

Here, you want something extremely small, with an extraction capacity measured in ounces rather than pints, because moisture is generally only a concern when the shower or tub is used. 

It also needs to be quiet and energy efficient. If this last requirement isn’t met, you’ll be trading one problem for another, having a drier bathroom at the expense of a skyrocketing electric bill. Not good. 

Considering those requirements, our top pick is the Gurin Mini Thermo Dehumidifier. It excels in all the categories we consider key for a device designed for use in a room where you spend a fair amount of time. Because it’s so quiet, you’ll barely know it’s running.

We’ll go into more detail below, together with other top contenders in this market segment.

Our Pick: Gurin Mini Thermo Dehumidifier

There’s a lot to like about Gurin’s Mini Thermo Dehumidifier model. It has all the key features you’d expect in a unit of this size and class:

  • A sixteen-ounce reservoir is sufficient for two or three days of continuous operation.
  • An auto-shutoff feature when the reservoir is full.
  • An indicator light to give you a visual marker when the reservoir is full.
  • An easy-empty tank.

It shares specifications with competitors in many respects, but its quietness sets the Gurin apart. You must put your head right next to it to hear it running. This is courtesy of its Whisper Quiet Technology and its design around “The Peltier Effect,” which is a highly efficient compressor build. You generally see this technology in circulatory fans attached to wood-burning stoves, which makes it interesting.

Since we’re talking about small bathroom dehumidifiers, you’ll spend a fair amount of time close to the device, so its noise level (or lack thereof) really matters. A somewhat noisy machine wouldn’t be a deal-breaker for many, but it would certainly not be a selling point.

These machines we reviewed are relatively functionally similar, so details like efficiency and noise matter. The Gurin matches the feature set of the Comforday unit (as we’ll see below), but it’s also quieter, ultimately putting it in the top spot.

Runner-Up: Eva-Dry Petite – Small Bathroom Dehumidifier

The Eva-Dry 1100 Petite Dehumidifier makes a solid product. Otherwise, it wouldn’t be on our list of top small dehumidifiers for bathroom use.

It is a relatively basic unit, however. This will be an excellent choice if you’re not interested in bells and whistles. Its simple and straightforward design makes it easy to use. Small enough to fit almost anywhere, easy access reservoir for dumping the water extracted, and it sips power.

There’s a lot to like here, and it hits all the necessary requirements; it just doesn’t shine at any of them. Even so, a solid, reliable little unit, attractively priced, and absolutely deserving of a spot here, just not the top one.

Also Great: Pictek Small Dehumidifier for Bathroom

​Pictek’s Mini Air Dehumidifier has all the same basic features you’d expect to find in a unit of this size, and it comes with the added security of its renowned customer service.

This isn’t the kind of unit you’d expect to have a major problem with, but since all of these devices are functionally similar, the smallest details count. Pictek’s customer service is reported as slightly better than Eva-Dry’s, which is why it noses out the Eva-dry model.

The two units look and function almost the same way, though, and again, there’s a lot to like about the unit. Its seventeen-ounce reservoir is sufficient for bathroom use, and the device is well-made and will last a long time.

It’s easy to use, too. Truly a “set and forget” kind of machine – just don’t forget to check and empty the reservoir every couple of days!

Honorable Mention: Comforday Portable Dehumidifier

The Comforday dehumidifier unit is above what you’d expect in a small bathroom dehumidifier. These units tend to be basic and short on features, which is why the indicator light, to act as a visual cue when the reservoir is full, is such a welcome and noteworthy addition.

Even better, the unit is comparable to the rest on this list, so the thoughtful addition doesn’t cost you anything, making it a solid win. The company is well known and respected, and their mini dehumidifier is quiet, reliable, and only sips power, making it an excellent all-around choice.

What Is the Best Small Dehumidifier for Bathroom 2024?

There are several excellent small dehumidifiers for bathroom use on the market, and most of them tend to have a pretty similar set of features. Because of this, the smallest of details can be the deciding factor in terms of which one is best. In this case, the major features you’re looking for are compact size, efficiency, and quiet operation. All items reviewed here meet those requirements, but the Gurin Mini Bathroom Dehumidifier truly shines and stands apart.
