Nothing beats drawing a nice hot bath after a long day. The candles are lit, your favorite album is on and the bubble bath has been generously applied. Yet nothing kills the mood quite as quickly as looking up to see mold and mildew growing on your walls and ceiling.

Despite bathrooms being temples of cleanliness (student dorms and bachelor pads excluded), they can often be plagued by black mold. The combination of humid air hitting cold surfaces results in condensation, which in turn provides fertile ground for mold to grow. If left unchecked mold will not only be an unsightly feature of your bathroom but can rot furnishings and can trigger allergic reactions, asthma, and other respiratory problems.

In order to tackle these issues in your bathroom, you first have to control the humidity. One of the most effective ways to control excess moisture is to utilize a dehumidifier, especially if your bathroom is poorly ventilated or it’s just too cold to open the window! 

By extracting moisture from the air, dehumidifiers are excellent tools for preventing mold and keeping your bathroom spick and span. In order for a humidifier to work at its best, be sure to choose one suitable for the size of your bathroom. For large spaces, we recommend the Midea, while the Pro Breeze is a great budget option for smaller spaces.       

When selecting our top recommendations, we analyze Consumer Reports to determine which dehumidifiers are best suited for the bathroom as well as reviewing genuine customer reviews to verify real users are satisfied with their performance. 

1. Midea 2019DOE

With a tank that can carry up to 50 pints of water, the Midea 2019DOE has the fantastic ability to maintain a healthy humidity of around 45%-55%. Since there are many settings, such as desired humidity and rate of usage, once you find the perfect settings, they will be preserved with the innovative auto restart feature. Now, even with power disruption such as a power outage, your dehumidifier will return to its set functions. 

Producing a low amount of sound (51 decibels), the dehumidifier will fade into the background noise, and carry the same volume level as a quiet conversation. Since the tank is included and set up right away, the only maintenance needed is draining the tank every so often when it fills up. With a standard .75-inch garden hose inserted into the socket in the back of the humidifier, gravity will drain the water and allow the machine to keep functioning properly. Not only is the tank installed for immediate use, but there is a reusable air filter that works to ensure better air quality without breaking the bank.

  • Tank Size: 50 Pints
  • Room Size Suitability: 4,500 Square feet
  • Weight: 33.5 pounds
  • Special Features: Turbo mode (high fan) and timer mode

What we love

  • The white noise adds a calming ambiance
  • Has 4 wheels and handles for easy moving around rooms
  • The sleek, white design blends in with modern decor
  • Easy assembly in about 15 minutes means faster dehumidifying

We don't like this as much

  • We’d like to see a timer function for this device for more precise operation
  • The tank gets heavy when it is full since it's a large size

2. Pro Breeze Electric Dehumidifier

Small but powerful, the Pro Breeze Electric Dehumidifier is portable and very easy to use. The tank included in the dehumidifier holds up to 9 ounces of water a day and can manage the humidity in a room up to 215 square feet. When the machine collects the maximum amount of water and needs draining, it will automatically shut off, and an LED light will turn on, notifying you. When draining, the water tank easily separates to be poured out. 

The Pro Breeze Electric Dehumidifier is quiet, making no more noise than a whisper, therefore providing great air quality while staying out of mind. Not only is it quiet and compact, but it requires very little energy, and is great for your personal electric usage, all while being much more eco-friendly than other dehumidifiers.

  • Tank Size: 1 pint
  • Room Size Suitability: 215 square feet
  • Weight: 2.4 Pounds
  • Special Features: Ultra-quiet Peltier technology

What we love

  • The unit is curved, giving it a unique design
  • Great for tackling mold in smaller rooms
  • Good for removing window condensation
  • The tank is a nice purple shade, which is a good accent against the white body

We don't like this as much

  • The tank is small, which means emptying it much more often
  • This unit is ideally used in small bathrooms, whereas larger ones may not receive the proper coverage

3. TOSOT 20 Pint Dehumidifier

The TOSOT 20 Pint Dehumidifier works flawlessly in spaces up to 1,500 square feet. In 24 hours, this tank can remove up to 20 pints of water from the air, making your bathroom a much more comfortable space to spend time in. When the tank is full of water, the dehumidifier will beep to remind you it’s time to drain. A unique feature of the TOSOT Dehumidifier is the different ways in which you can drain the tank. If you want to drain the bucket of water, the spill-proof bucket can be lifted out directly and emptied from the machine. Though, if you don’t want to carry the heavy 1-gallon capacity bucket, you can connect a hose and drain the water that way. 

On the control panel, you can choose a target humidity for the automatic shutoff. While it’s working, the panel will show the current humidity level, and simply shut off when it hits the target range. In nonstop mode, there is no automatic shutoff at a target, and the machine will continue to run until you adjust it.

  • Tank Size: 20 pints
  • Room Size Suitability: 1500 square feet
  • Weight: 33.9 pounds
  • Special Features: Target setting means automatic shutoff at your desired humidity level

What we love

  • At each setting, the decibel level of the sound is as light as rainfall
  • The air filter included is washable and easy to remove
  • Available in different sizes with larger tank capacities
  • Built-in overflow protection to prevent spills from occurring

We don't like this as much

  • The plug to the hose attachment can be tricky to remove
  • We’d like to see a remote control feature for those who want to adjust the settings while in the bath

4. Vacplus 30 Pints 1,500 Sq. Ft. Dehumidifier

This compact, functional dehumidifier works to remove up to 30 pints of water from the air each day. When it fills up, the indicator light will turn on, and, to make it easy on your preferences, you can either take out the tank to dump it or use the included hose to drain it. Since daily life is ever-changing, there may be days where you need to run the dehumidifier for longer than others, and other times where you don’t need it running at all. 

To minimize the daily contact with the machine itself, it is possible to set a 24-hour timer to program it to turn on and off when needed. Using only a small amount of energy, the dehumidifier is also kind to your energy bill, proving that it can be cost-effective to make your bathrooms more comfortable. There are some optional modes included, such as a drying clothes mode, which will dry your wet clothes with the touch of a single button!

  • Tank Size: 30 pints
  • Room Size Suitability: 1,500 square feet
  • Weight: 20.9 pounds
  • Special Features: Drying clothes mode and an included drainage hose

What we love

  • Target humidity can be set in order to save energy with auto-shutoff
  • The filter can be vacuumed or wiped clean
  • Has compact wheels that make it easy to move to different rooms
  • Great for drying towels after showers

We don't like this as much

  • Due to the use of a compressor, the sound may be slightly more noticeable
  • The drainage tube may leak if not attached tightly enough

5. Afloia Electric Home Dehumidifier, Portable Dehumidifier

The Afloia Electric Portable Home Dehumidifier is a great, portable dehumidifier that works to quickly improve air quality and create a better overall indoor environment.

The Afolia Home Dehumidifier is capable of removing 11 ounces of water from the air daily and has a removable tank for easy drainage. 

When the tank is full, the dehumidifier will automatically turn off in order to prevent overflowing or damage. Operating at a low volume of 35dB, it will be easy to keep the machine running all day and not even notice it’s there. Manage musty smells, water condensation, smelly clothing, and damp walls or corners by running the easy-to-use Afloia Electric Portable Home Dehumidifier!

  • Tank Size: .65 pints

What we love

  • Very compact, making it ideal for not taking up a lot of space in small rooms, such as the bathroom
  • Comes in a sleek white and light blue design
  • The LED light will turn on to indicate when it is on or off

We don't like this as much

  • Though the LED light is useful, it is bright
  • Designed for smaller rooms, this dehumidifier may not work as efficiently in larger rooms

6. Ivation 13-Pint Small-Area Desiccant Dehumidifier

The Ivation 13-Pint Small-Area Desiccant Dehumidifier is a wonderful addition to any home to remove moisture from the air, prevent odors and mold, as well as providing warm air. Though the machine is small and compact, it is very capable of quickly dehumidifying spaces up to 270 square feet. 

Using the control panel on the top of the machine, it is possible to set humidity controls, as well as power levels and overall functioning. With an on/off button, a mode button to switch between low, high, and sleep modes, and a humidity button to set the desired humidity target, the controls for this dehumidifier provides you with all the utility you would need.

Some other options available include the ability to change the brightness of the LCD screen, setting a timer to easily manage usage times of the machine, and swing mode, which is able to adjust the movement of the air vents in order to help clothes dry faster. For drainage, there are two options to empty the tank, as you could either take the tank out or use the included hose to drain out of the spout.

  • Tank Size: 13 pints
  • Room Size Suitability: 270 square feet
  • Weight: 13.96 pounds
  • Special Features: Easy-clean filter and Anti-tilt shutoff

What we love

  • Special desiccant rotor works to provide better dehumidifying features
  • Has a handle for easy moving
  • The machine will automatically shut off if there is a threat of tipping over
  • LCD display with change from Fahrenheit to Celsius for easy use

We don't like this as much

  • Since it does produce heat, it may be less convenient to use in the hot months
  • We would like to see the ability to use a standard garden hose to drain the tank, as the included hose is not compatible

7. Pure Enrichment® PureDry™ Mini Dehumidifier

The Pure Enrichment® PureDry™ Mini Dehumidifier is a sleek, attractive dehumidifier that works to remove moisture from the air and add a modern touch to your home décor. In the front of the machine, the design is a rounded white frame, showing a slit in the bottom for a view of the tank, allowing you to watch the water level. At the back of the setup, there is an on and off switch, a LED light to indicate when it is on, as well as another LED to show when it is full. 

Under the vent on the back is a transparent blue tank that allows you to track how well it is working in your room and when it is going to need to be drained. Either way, when the tank fills, the LED light will turn on indicating it needs to be emptied, and the machine will automatically turn off to reduce the risk of overflowing.

  • Tank Size: 1.6 pints
  • Room Size Suitability: 110 square feet
  • Weight: 3 pounds
  • Special Features: Transparent water tank for easily monitoring water level

What we love

  • Includes an AC power adapter

  • Works year-round to combat the seasonal changes in humidity
  • Amazing for small, compact spaces like a bathroom

We don't like this as much

  • An option to set preferred humidity level would be welcomed
  • Air comes out of the top, which means the dehumidifier needs a bit of clearance above it

8. Eva-dry Edv-1100 Electric Petite Dehumidifier

Known for producing significantly less noise than other dehumidifiers, the Eva-dry Edv-1100 Electric Petite Dehumidifier is great for improving air quality while also providing a great night sleep with its whisper technology. Simple to use, all you need to do is plug in the dehumidifier and switch the button on. Due to its small size, it is easy to place in any small room or bathroom while quickly working to remove large amounts of moisture from the air. 

With a tank that will hold up to 16 ounces, you can leave the machine running all day and drastically improve the air quality. When the bucket fills up, an LED light will turn on and the machine will shut off to prevent overflow, and the tank can be easily removed from the front of the dehumidifier.

  • Though it is small, it works as fast and as well as other, larger dehumidifiers
  • Because of its tall design, the tank is easy to carry and drain

We don't like this as much

  • The dehumidifier must be drained manually; a drainage hole for a hose would be welcome
  • Though it is simple to drain, the pour hole is small, which means it takes a bit longer to fully empty


Where should a dehumidifier be placed in a bathroom?

Since your dehumidifier is there to take moisture out of the air, it is important to place it somewhere where there is a lot of access to the moisture in your bathroom. For instance, a counter placement closer to your shower may be a more effective location to remove excess shower steam than placing the dehumidifier on the floor.

The filter, in any case, should have at least 12 inches of space between it and a wall or the bottom of an overhead counter. This way it is able to run much more efficiently as it isn’t cut off by any obstructions. Some dehumidifiers are small, and some are larger, which will affect their ideal placement.

How often should I empty the water tank in my Dehumidifier?

Each dehumidifier will have a different size tank, which affects the number of times you may need to empty it. It also depends on the amount of water in the air or the number of people using the bathroom for showers and baths. Luckily, many dehumidifiers have an auto-shutoff feature or an LED light that turns on when the tank is full, making it easy for you to know when to empty out the water.

Is it safe to take a shower when a dehumidifier is in operation?

Because dehumidifiers are electric and some emit hot air, it is significantly safer to keep them off while in the shower. This way, you reduce any risk of your machine short-circuiting or overworking and overheating. If you want to keep it on, it isn’t impossible, but it’s important to keep the cord and machine as a whole away from potential splashing or water spray as you take a shower. Just like any electrical device, water isn’t an ideal thing for your dehumidifier to come into contact with, but it can still be run if monitored.

Which Dehumidifier is best for you?

Choosing the correct dehumidifier may require a bit of research, but the right one will transform the humidity levels in your home and make it much more comfortable for you and those in your home. Assess important factors, such as budget, room size, tank size, amount of people using a bathroom, and special features when choosing a dehumidifier.

If you have a big bathroom with a lot of people using it, a dehumidifier with an auto-shutoff, a big tank with the option for draining with a hose, and the ability to set a target humidity is very important. Though it may be more expensive, it is going to save time and function better in the long run. On the other hand, if you have a smaller bathroom with only one or two people using it, it may be more budget-friendly to get a smaller, portable humidifier.

No matter your bathroom conditions, there is a perfect dehumidifier out there, and buying it is going to transform the humidity and comfort of your bathroom.
