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! 

Bathroom size in the United States ranges from small (35 sq. ft.) to very large bathrooms (210 sq. ft.) You will see many dehumidifiers are recommended for far bigger spaces than that but you need to be aware that these recommendations are made without assuming the unit will be used to help dehumidify a bathroom.

When it comes to dehumidifying a bathroom, the Home Ventilation Institute recommends an extra 50 CFM for a dehumidifier to be effective. So, if you are planning to take a shower and want to remove moisture as quickly as possible, then you need a dehumidifier that has the ability to move a lot of air, which it’s standard with the larger units. So for most people looking for a bathroom dehumidifier with the ability to remove 30 pints of water is perfect, and for smaller bathrooms, you can get away with less with a smaller dehumidifier.

Whilst small dehumidifiers seem like the perfect fit for bathrooms, we would suggest looking at larger units if you really want to deal with a lot of moisture created in average to large-sized bathrooms as mini-units will find it hard work to remove enough moisture before it fills the room.

We want to provide you with useful guides that help you look beyond marketing hype, and the dehumidifiers below tick all the boxes for a dehumidifier that will do the job in the bathroom. 

1. Best for Most Bathrooms: Honeywell TP30WKN

The Honeywell TP30WKN didn’t get voted the best dehumidifier by Consumer Reports for no reason.

Honeywell has been in the game for many decades bringing both high-efficiency dehumidifiers and air purifiers to the market. With the TP30WKN they’re aiming at those with spaces of 1000sqft that need moisture removal but this unit is also perfect for the bathroom.

You might be saying to yourself “1000 sq. ft. is a little over the top for my bathroom”, but if you are planning to use your shower or bath, you will want a dehumidifier that can work quickly to remove the moisture from the air.

The Honeywell couldn’t be easier to use. The tank slides in/out with ease to empty and when it’s full, the unit will alert you and automatically shut off to make sure it doesn’t overfill and spill over. The interface on the top of the unit is also easy to operate. 

You can adjust your desired humidity level using the digital display, set the timer, engage sleep mode, and it lets you know when the filter needs washing. If all that isn’t enough to convince you, it also comes with wheels and a heavy-duty handle to easily move from room to room or around your bathroom.

SPECS & FEATURES

Moisture Removed (24hrs):30 Pints
Recommended room size:1000 sq. ft. 
Weight (in pounds / in kg):42.9 lbs / 19.5 kg
Special features:Auto Restart, Full Tank Alert w/ Auto Shutoff, Filter Clean Alert, Auto Defrost Control

What We Really Like:

👍 Has a continuous drain option if you have a hose attachment
👍 There are 2 fan speeds to select
👍 It has thermal overload and fuse protection
👍 Features an automatic defrost control

What We Think Could Be Better:

👎 Can seem quite loud on the highest fan speed
👎 Doesn’t have a low-temperature operation (41 degrees and below)

2. Best for Large Bathrooms: 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. Even with power disruption such as a power outage, your dehumidifier will return to its set functions. 

Producing a low level of noise (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.

SPECS & FEATURES

Moisture Removed (24hrs):50 Pints
Recommended room size:4500 sq. ft. 
Weight (in pounds / in kg):33.5 lbs / 15.2 kg
Special features:Turbo mode (high fan) and timer mode

What We Really Like:

👍 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

What We Think Could Be Better:

👎 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

3. Best for Medium to Large Sized Bathrooms: hOmeLabs 4,500

Another unit for those with larger bathrooms or for people like me that need it for different rooms but don’t want to fork out for a dehumidifier for each space, this Amazon top seller from hOmeLabs will take care of rooms up to 4500 sq. ft. 

It has the capacity to remove 50 pints of moisture in a 24-hour cycle by either collecting it in its tank or continuously through a drainage pipe that can be easily attached to the back. 

This Energy Star Certified dehumidifier doesn’t break the bank to operate, especially as it will clear the excess moisture from your bathroom in no time at all. 

There are a few cool features on this unit that makes it stand out from the rest. Not only has it got a timer, humidity level adjuster, filter alert, and turbo mode, but hOmeLabs have treated us to a Comfort Mode. When engaged, the unit will automatically set a comfortable and healthy humidity level based on the ambient temperature of the room. 

Ideal for a loooooong soak in the tub.

SPECS & FEATURES

Moisture Removed (24hrs):50 Pints
Recommended room size:4500 sq. ft. 
Weight (in pounds / in kg):40 lbs / 18.1 kg
Special features:1-24hr timer, Turbo mode, washable filter

What We Really Like:

👍 It has a washable air filter
👍 You can monitor moisture capacity through its tank window
👍 Comes with a 1-year warranty
👍 Has wheels and a handle for maneuverability 

What We Think Could Be Better:

👎 If a drain hose was included
👎 It’s larger than other models

4. Best for Medium Sized Bathrooms: TOSOT 20 Pint Dehumidifier

The TOSOT 20 Pint Dehumidifier works flawlessly in spaces up to 1,500 sq. ft. 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.

SPECS & FEATURES

Moisture Removed (24hrs):20 Pints
Recommended room size:1500 sq. ft. 
Weight (in pounds / in kg):33.9 lbs / 15.4 kg
Special features:Target setting means automatic shutoff at your desired humidity level

What We Really Like:

👍 At each setting, the noise level 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

What We Think Could Be Better:

👎 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

5. Most Stylish Design: Vacplus 30 Pint 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 depending on your preference 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!

SPECS & FEATURES

Moisture Removed (24hrs):30 Pints
Recommended room size:1500 sq. ft. 
Weight (in pounds / in kg):20.9 lbs / 9.5 kg
Special features:Drying clothes mode and an included drainage hose

What We Really Like:

👍 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

What We Think Could Be Better:

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

6. Best for Small Bathrooms: Ivation 13-Pint 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 provide warm air. Though the machine is small and compact, it is very capable of quickly dehumidifying spaces up to 270 sq. ft. 

Using the control panel on the top of the unit, 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 provide 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.

SPECS & FEATURES

Moisture Removed (24hrs):13 Pints
Recommended room size:270 sq. ft. 
Weight (in pounds / in kg):13.96 lbs / 6.33 kg
Special features:Easy-clean filter and Anti-tilt shutoff

What We Really Like:

👍 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

What We Think Could Be Better:

👎 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


The One Dehumidifier We Don’t Recommend: Pro Breeze Electric Dehumidifier

The Pro Breeze Electric Dehumidifier does have some pros. 

It’s portable and very easy to use. 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 problem is, in our tests, it didn’t really seem to do much at all. The price tag of the Pro Breeze tells you everything you need to know. It’s cheap and ineffective. This unit features in quite a few ‘Best’ lists from other sites, but we actually tested it in a real-world environment and were really let down by the results.

We would highly recommend spending a little more money and investing in a unit that won’t leave you high and (not) dry.

If you have a small space and have a super tight budget then choose the Pohl Schmitt instead – it is not only cheaper but it’s also A LOT more powerful.

SPECS & FEATURES

Moisture Removed (24hrs):1 pint
Recommended room size:215 sq. ft. 
Weight (in pounds / in kg):2.4 lbs / 1.1 kg
Special features:Ultra-quiet Peltier technology

What We Really Like:

👍 The tank is a nice purple shade, which is a good accent against the white body

What We Think Could Be Better:

👎 The tank is small, which means emptying it much more often


Frequently Asked Questions About Having a Dehumidifier in the Bathroom

🤔 Do I need a dehumidifier in my bathroom?

Many people will have no need for a dehumidifier as they will have adequate air flow using an integrated fan that will remove moisture before it can become a problem. But if your bathroom can’t access the outside then a dehumidifier can provide a fix to the problem. If possible you should always look to use ventilation as it’s far more effective and less cost long term than choosing a dehumidifier but we totally understand that fitting an exhaust fan is not something that is an option for everyone and if you do choose a dehumidifier for your bathroom then be sure to go for a unit that is effective as the Honeywell unit we reccomend.

🤔 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.

🤔 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.

🤔 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.

🤔 So… 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 are 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.
