Best Bathroom Dehumidifiers to Keep Your Bathroom Dry

Here are the best dehumidifiers for bathrooms to help eliminate moisture in your bathroom. Keeping your bathroom dry helps to prevent mold and mildew.

Bathrooms have the tendency to accumulate a lot of moisture, which can lead to humidity problems. Mold and mildew love high humidity areas.

That’s why you’ll find it growing in bathrooms and damp corners of your house. Mold and mildew are not only gross, but they can also be harmful, especially to people with allergies.

The good news is that you can eliminate most of the moisture with a good dehumidifier and make the bathroom or even the whole house dry and safe.

4 Best Dehumidifiers for Bathrooms

#1. MIDEA MAD50C1ZWS – Best Dehumidifier for Large Bathrooms

MIDEA MAD50C1ZWS Dehumidifier for up to 4500 Sq Ft with Reusable Air FilterMIDEA MAD50C1ZWS Dehumidifier for up to 4500 Sq Ft with Reusable Air FilterMIDEA MAD50C1ZWS Dehumidifier for up to 4500 Sq Ft with Reusable Air Filter

The Midea MAD50C1ZWS is one of the most powerful dehumidifiers you can have in your bathroom. Featuring 4500 sq. ft. coverage, it’s ideal for the bathroom, basement, bedroom or any other part of your house that has high humidity levels.

You can also adjust the level of humidity between 35% and 85% based on the room you place it in.


As mentioned earlier, bathrooms accumulate a lot of moisture. That’s why I recommend this model since it extracts 50 pints (about 8 gallons of water) within 24 hours.

Moist air is drawn in by the fan and run through the reusable filters to eliminate the moisture.

The moisture is drained into the tank while the dry air is then warmed and re-introduced into the room.

Water Tank and Drainage

The 1.6 gallons (6 liters) tank is sizeable, meaning you don’t have to empty it often. The tank even has a visible section that allows you to monitor the water levels.

Better yet, you also have an option to drain it continuously using a hose. This method uses gravity, so you don’t have to worry about purchasing an extra pump or paying a higher electricity bill.

Additional Features

Below are extra features that enhance the performance of this dehumidifier.

  • Auto-Restart – This feature allows the unit to restart itself in case there is a power outage. It also saves the settings in place before it went off, allowing it to run automatically even when you’re not around.
  • Clean Filter Indicator – This is a convenient alert system that reminds you when to clean the filters.
  • Turbo Mode – In this mode, the fan draws in a lot of air within a short time to get rid of excess humidity.
  • Auto-Defrost – If your room is too cold, the water in the dehumidifier may freeze on the fan, affecting the dehumidifier’s operation. The auto-defrost feature automatically clears this icing to allow the unit to keep functioning.
  • Timer Mode – If you don’t want the dehumidifier running 24/7, you can set it to work for a few hours, then stop. The timer ranges from 0 to 24 hours.
  • Auto-Comfort – In this mode, the unit automatically maintains the ideal humidity levels by extracting the necessary amounts of moisture from the air.
  • Smaller Options – If 50 pint is too large for your bathroom, you can also opt for the 20-pint or 35-pint models.

User Impressions

Most users acknowledged how powerful this unit is, especially in bathrooms and basements where humidity can get to high levels.

But they also noted that even though the tank is large, it filled up pretty fast, so you’re better off using the draining pipe instead.

Some users also complained about it being noisy and quite expensive to run. But the timer is convenient in reducing electricity bills.


  • Very powerful dehumidifier
  • Easy to set up and operate
  • Wide coverage


  • It’s expensive to run 24/7
  • It can be too noisy sometimes

#2. TOSOT 20-Pint Dehumidifier

TOSOT 20 Pint 1,500 Sq Ft Dehumidifier Energy Star, Super QuietTOSOT 20 Pint 1,500 Sq Ft Dehumidifier Energy Star, Super QuietTOSOT 20 Pint 1,500 Sq Ft Dehumidifier Energy Star, Super Quiet

If you’re looking for a smaller dehumidifier for just the bathroom or prefer the minimalistic design, this TOSOT model suits you. But they also have larger versions of this model.


This model extracts 20-pint (about 10 liters) of moisture from the air every 24 hours and covers up to 1500 sq. ft.

Considering most bathrooms are usually less than 100 sq. ft., this dehumidifier can work in the bathroom and the whole house.

Like in most dehumidifiers, the air is run through washable filters, where the water is drained into the tank while the dry air is blown back into the room.

Water Tank and Drainage

The Tosot 20-pint dehumidifier comes with a 1-gallon bucket, which fills in about 5 hours.

It also has a beeping alert system that lets you know when to empty the tank. But if you don’t want to empty it often, you can connect it to a drainage pipe using a standard 3.75-inch hose.

It also supports the use of a pump if drainage through gravity isn’t applicable.

Operation and Energy Efficiency

The manufacturer claims that this device is quiet, with 52 dB in noise levels. Well, that’s a tolerable noise level for a dehumidifier, and I didn’t find it too noisy either.

But we’ll see what other users have to say. Being Energy-Star rated, you can rest assured that this device will not drown you in electricity bills.


The filter needs to be washed after regular usage. But don’t worry about remembering when to clean it since there’s a reminder on the display screen.

Additional Features

Below are two more features that make this a powerful dehumidifier.

  • Auto-Restart – This feature allows the dehumidifier to keep functioning after a power outage without at the same settings you had in place prior to the outage.
  • Humidity Display – This unit displays the room’s current humidity, allowing you to set a target to the amount of moisture it should dehumidify. Once it gets to this humidity level, it will stop running. You can also opt to keep it running continuously regardless of the humidity levels.

User Impressions

Besides being quite efficient for such a small size, users also agreed that it wasn’t too loud. Most buyers used them for the bathroom, basement and for the whole house.

However, some found the tank too small for high humidity areas. There are some complaints about leaks, defective parts, and breakages within the first few months.

Luckily, it comes with a 1-year warranty, so reach out to the manufacturers in case of any of these issues.


  • Easy to operate and maintain
  • Quiet operation
  • It’s compact
  • It’s energy efficient


  • The water tank is too small

#3. Eva-Dry EDV-1100 Petite – Best Budget Dehumidifier for Small Bathrooms

Eva-dry Edv-1100 Electric Petite DehumidifierEva-dry Edv-1100 Electric Petite DehumidifierEva-dry Edv-1100 Electric Petite Dehumidifier

A bathroom dehumidifier doesn’t have to be expensive. If you only have less than $100 to spend on a dehumidifier, you should check out the Eva-Dry EDV-1100.

Does this mini dehumidifier really help to keep the bathroom dry? Let’s find out.


This unit extracts up to 8 ounces of water per day and has an approximate coverage of up to 1100 cubic feet. This makes it perfect for small bathrooms, apartments, laundry rooms, and closets.

Due to this coverage, you can’t use it to replace your whole-house dehumidifiers.

Water Tank and Drainage

This unit has a 16-ounces tank, which means that if your bathrooms have low humidity levels, you may have to empty it at least once or twice in 2 days. Unfortunately, it lacks an option to drain using a drain pipe. So you’re stuck with emptying it every couple of hours if your bathroom has high humidity levels.

The EDV 1100 is also pretty small, so carrying it, even with the tank full, won’t be a problem. 

Better yet, when the tank is full, it alerts you, and the unit shuts off automatically. Once you remove the tank, empty it, and place it back, it automatically resumes operation.

Operation and Energy Efficiency

With noise levels of 50 dB, this unit is relatively quiet. You can have conversations, listen to music, or have your quiet time as it runs.

The manufacturer also states that it draws 22 watts, which isn’t much compared to other appliances, such as bulbs. So, like with most small dehumidifiers, this unit will not make a significant impact on the electricity bill.

Additional Features

Unlike the other units that give you programmable features, this unit is as simple as it can get.

It only has an on/off switch and an LED light. This light is green when the dehumidifier is in operation and yellow when the tank needs to be emptied. And that’s it.

If you’re looking for more functionality or more coverage, check out the Tosot 20pint or the Midea 50-pint models.

User Impressions

The EDV 1100 has received many positive reviews (63%)) compared to other dehumidifiers of the same size. This shows that most people are impressed by its performance.

Most users loved its quiet operation, small design, and efficiency in bathrooms, RVs, and even boats.


  • Lightweight and very portable
  • Easy to use
  • Excellent value for money
  • Quiet operation


  • It has limited coverage
  • You can’t continuously drain the tank with a drain pipe

#4. Inofia 30-Pint Bathroom Dehumidifier

Inofia 30 Pint 1500 SQ FT Home Dehumidifier with Continuous Drain HoseInofia 30 Pint 1500 SQ FT Home Dehumidifier with Continuous Drain HoseInofia 30 Pint 1500 SQ FT Home Dehumidifier with Continuous Drain Hose

The Inofia 30-Pint is another compact dehumidifier that’s perfect for your bathroom. And unlike the Eva-Dry EDV-1100, it gives more control of the settings and draining options.


This unit extracts up to 4 gallons of water within 24 hours in a 1056 sq. ft. room.

It can also work in temperatures as low as 41 degrees F (5 degrees Celsius) thanks to the auto-defrost feature. This feature makes it the best dehumidifier for bathrooms, basements, garages, and all other rooms where temperatures tend to go close to freezing point.

Water Tank and Drainage

The Inofia 30-pint has a 0.5-gallon tank. I know this isn’t that large, considering it dehumidifies up to 4 gallons, but most rooms can’t have that much humidity daily.

The unit shuts off automatically once the tank has reached full capacity, and it’s pretty easy to remove when you need to empty it.

The manufacturer also provides a 5.65 feet hose that allows you to auto-drain the water from the tank.

Operation and Energy Efficiency

This dehumidifier works right out of the box. Just plug it in, and the air in your bathroom gets noticeably dry within a few hours.

What you’ll love most is the easy-to-use panel. You can set the dehumidifier to work continuously or select your ideal humidity level between 30% and 80%.

The humidistat helps the unit measure the current humidity in the room.

Once the room humidity gets to the set level, the dehumidifier will stop running and starts running again when the levels exceed your target.

The unit is also tranquil, with noise levels of 46 dB. It’s also certified as energy-efficient; so operating it in addition to other electronic appliances will not be a problem.


This dehumidifier is relatively easy to maintain. For starters, the filters need to be cleaned regularly. The auto-defrost I mentioned earlier is an automatic maintenance feature that prevents the icing up of the internal parts.

It has an Auto-Error Detection feature that shows an error code if the unit breaks down. You can check the corresponding fixing tips associated with the error code on the manual or contact customer care.

Tips for First Time Use

The manufacturer advises that you let the unit settle for at least 24 hours before plugging it in for the first time.

User Impressions

At the time of writing this, the Inofia 30-pint dehumidifier had 2600 reviews on Amazon, and 71% of those were 5-star reviews. This goes to show how well it solves most users’ humidity problems.

These reviews are from people in areas that receive lots of rain, people dealing with mold and mildew allergies, and people dealing with musty smells.

They loved how fast it changed the humidity levels and how quiet it was.

However, some users complained about its coverage area, but since we only need it for the bathroom, it’s more than enough for such spaces.


  • Lightweight and portable
  • Quiet operation
  • It has both manual and auto drain
  • It’s energy efficient


  • The water tank is quite small

Best Dehumidifiers for Bathrooms Buyers’ Guide

While you could get rid of excess humidity using fans or just opening the windows, nothing beats having a dehumidifier. Not only do they extract moisture, but the filters will also trap dust particles, making the air in the bathroom cleaner.

I may not have exhausted all the great dehumidifiers for bathrooms, but below are some of the things you should consider when choosing one.

Water Tank Capacity

This is one of the most critical factors. If you go for a tiny tank, you will have to empty very often, and if you for a huge tank, portability will be an issue. So it’s a matter of balancing the estimated amount of moisture in the bathroom and the tank’s size.

If your rooms are prone to humidity, a larger tank and an auto-drain option would be ideal.

Another benefit of larger dehumidifiers is that you don’t have to run them 24/7 to maintain ideal humidity levels.

Dehumidifying Rate

This is the amount of water/moisture a dehumidifier extracts every 24 hours. The largest model I reviewed here is the Midea, which is a 50-pint dehumidifier.

Now this one is ideal for very large bathrooms or laundry rooms. But for standard bathrooms, a 20-pint or 30-pint dehumidifier will do.


This is the area a dehumidifier covers at a time, and it’s measured in square feet or cubic feet.

The larger the bathroom, the more you’ll need a dehumidifier with wider coverage.

A standard bathroom is approximately 40 square feet, but it’s possible to have larger bathrooms. Most dehumidifiers have coverage of more than 500 square feet, so it’s easy to find one that will suit your bathroom.

Noise Levels

A good bathroom dehumidifier shouldn’t be too loud. You don’t want the sound distracting you or your guests. The ideal noise output should be 50 dB or lower, or simply the sound of a fan on low-speed settings.

Power Consumption

High-performance models can consume a lot of power, but they also extract moisture from the bathroom faster.

Smaller thermo-electric dehumidifiers, on the other hand, are slower and have little to no impact on the electricity bills.

If your room is prone to high humidity, a more powerful model would be better.

Again, due to the small size of most bathrooms, you don’t have to run them all the time, saving you money in electricity bills in the long run.

Extra Features

Additional features improve the performance of a dehumidifier and give you more control over how to use it.

One feature I think the best dehumidifier for bathrooms should have is the auto-defrost. Bathrooms tend to be quite cold, especially if you live in colder climates.

And dehumidifiers work by condensing the water to deposit it in the tanks. But if it’s too cold, this water turns into ice on the fan before entering the tank. The auto-defrost ensures this doesn’t happen.

Other features include the humidity settings, the humidity display, auto-shutoff for when the tank is full, and auto-restart, which saves the settings prior to a power outage.

Tips for Keeping Your Bathroom Dry

  • Besides getting a bathroom dehumidifier, below are more ways to prevent excessive moisture build-up.
  • Wipe and drain excess water after using the bathroom.
  • Make sure there are no leaks from the showers, water pipes, or even from the dehumidifier.
  • Ensure there’s adequate ventilation in the bathroom.
  • Avoid leaving wet laundry in the bathroom.


A dehumidifier is a must have for a bathroom since moisture tends to build up easily in the bathroom. Regardless of the size of the bathroom, or the moisture levels, there’s a dehumidifier suitable for you. The Midea 50-Pint Dehumidifier is excellent for huge bathrooms or as a whole-house dehumidifier, and the Eva-Dry EDV-1100 is great for very small bathrooms and those on a budget. The Inofia 30-Pint and TOSOT 20-Pint Dehumidifiers are the best for standard bathrooms.
