If you live in an area where there’s either high rainfall or which has a really humid climate, you are likely to suffer from humidity issues.
Many spaces and areas inside your home might be subject to high humidity, such as basements and bathrooms.
Of those two, bathrooms are unquestionably the most common area to experience a high humidity level.
There are many reasons why the air inside bathrooms has high levels of humidity, such as water problems, pipe leakage, clogged pipes, and many others.
Humidity can also occur for reasons such as not switching on the exhaust fan after a shower, leaving a puddle of standing water on the bathroom floor while cleaning, and not having enough air circulation in the enclosed space.
But the most common cause is that your bathroom is used for bathing in hot water, which creates steam, and that steam adds to the overall humidity level felt in the room.
Regardless of the reason, high humidity levels not only cause structural damage but can also adversely affect your health.
Of the numerous available solutions for getting rid of humidity in bathrooms, a dehumidifier is the most effective and efficient way of dealing with a humidity problem.
These handy little devices remove excess moisture from the air as well as preventing the growth or spread of mold and mildew.

Although the Pro Breeze electric dehumidifier is a winner product and an excellent dehumidifier for bathroom use, it does have a few downsides.
One of the major drawbacks of this product is that it isn’t energy efficient, which means that it will cost you a little too much in the long run.
In other words, it tends to be a little heavy on the pocket.
This dehumidifier model uses thermoelectric cooling technology which operates without a compressor. This makes the machine incredibly quiet, and to be honest, the operating noise level is so low it’s almost inaudible.
Another super useful feature of this machine is the handy water outlet present on the tank that allows you to drain the water without creating any mess.

Runner-Up: Honati Home Dehumidifier
The Honati Home Dehumidifier is the second-best option as a dehumidifier for bathroom use, with some of the most impressive and useful features. It comes with a 2000 ml water tank capacity that can easily remove about 750ml of moisture per day from your bathroom.
Like the previous dehumidifier for bathrooms, this one also features an auto shut-off function that greatly prevents an overflow of water or flooding in your bathroom.
Once the tank becomes full, the machine switches off, and the LED indicator light turns yellow to indicate that the water needs to be drained and replaced.
This dehumidifier is made of plastic and weighs only 5.64 lb, which makes it super lightweight, compact, easy to operate, and highly portable.
As good as this bathroom dehumidifier is, it is unfortunately really loud and noisy. There’s a constant noise of the motor that runs it, which can get really annoying, especially during times when you really want peace and quiet.
This also tells you this device does not Peltier technology for quiet operation, although this isn’t usually required of a dehumidifier for bathroom use.
Another drawback of this dehumidifier is that the plug that comes with it doesn’t always stay in place when you connect it to the unit.
It’s quite loose and keeps falling out, which greatly hinders the smooth operation of the product.
One of the best things about the Honati Home Dehumidifier is that it is eco-friendly and energy-saving – it has a very low power consumption level.
Basically, this dehumidifier model consumes very little energy and also doesn’t waste any electricity. This also makes it very cost-effective, thus preventing you from having to pay high energy bills.

If you’re particularly looking for a compact and user-friendly dehumidifier for your bathroom, this could be one of the best dehumidifiers for you. Although it tends to be quite noisy, it shouldn’t be that big an issue since you’ll be keeping it in your bathroom only.
So, the chances are that you probably won’t be bothered by the noise level as much.
But the thing is it also does a fantastic job of maintaining balanced moisture levels in your bathroom.
So you should still consider this as one of the best dehumidifiers in our roundup.
Alternatives: MIDEA MAD20C1ZWS Portable Dehumidifier
The MIDEA MAD20C1ZWS is an excellent choice as a bathroom dehumidifier solution, considering how it promises to promote a healthy environment and ensure better quality air in bathrooms. It helps to maintain the ideal humidity level that lies anywhere between 45%-55% and further also adjusts the humidity from 35% – 85%.
It comes with a 0.8-gallon capacity tank, which is the equivalent of 3,000ml of water.
This makes it an ideal solution for a large, medium, or small bathroom – it provides a coverage area of up to 1,500 square feet.
It is very easy to remove the tank, empty the water into the sink, and then replace it.
To make it even easier, the dehumidifier comes with a built-in socket where you can attach a 0.75-inch continuous drain hose to remove all gathered water without any intervention on your part.
So are there any reasons why this wouldn’t be the best dehumidifier for bathroom use?
While putting together this mini buying guide, we noticed it has two major drawbacks.
Firstly, it tends to be very loud because the fan motor produces a constant humming and vibrating sound.
Secondly, the inbuilt hose socket that comes with the tank for gravity-fed draining begins to leak exactly at the point where the hose connects to the main water tank.
It’s also a real shame this model doesn’t feature a continuous drain hose option.
Like many other top bathroom dehumidifiers, this one also features an auto shut-off function that helps you set the machine and then forget all about it.
It has a 24-hour timer, so it’s easier to control when it’s in use – this makes it very user friendly because it helps reduce your energy bill.
However, one feature that sets it apart from the rest is the ‘auto-restart function’ that prevents disruption caused by power outages. It does this by resuming the settings that you set earlier as soon as the power comes back on.
Additionally, this dehumidifier comes with a useful ‘auto defrost’ feature that prevents the water in the tank from freezing, which, in turn, is highly beneficial for the machine as it protects it from harm.
You will particularly love the reusable air filter that comes with this product, which prevents you from having to buy expensive replacement parts every now and then.
Despite a couple of drawbacks associated with this product, it delivers impressive performance by maintaining ideal humidity levels in your bathroom and offering massive capacity.
And it does this while still being Energy Star certified, which is impressive.
One thing that some of you might particularly like is that the water tank that comes with the machine is see-through.
So, every time you are in the bathroom, you can easily tell if the tank needs to be drained.
All these features make this a great dehumidifier – for bathroom use and maybe even elsewhere in your home.
It really is a great dehumidifier solution for larger bathrooms (and other rooms), for the price.
Hysure Direct Portable Dehumidifier
Small in size, but big on functionality, the Hysure Direct features a 700ml water tank capacity.
This provides a coverage area suitable for bathrooms in the 150-square feet range. It has been designed with a single-button control panel, which makes it very easy for users to operate.
One of the major benefits of this dehumidifier is its simple design that not only ensures a smooth and easy single-touch operation function – there’s no complex control panel – but it also significantly lowers the machine’s malfunction rate.
It is also super tiny and easy to hold and carry, making it really portable, handy, and convenient to use.
So you can also use it in other rooms where you want to prevent mold, mildew, and an overall smell of dampness from developing.
One of the main downsides of this dehumidifier is that it’s not very efficient for a large space- it can only remove up to 300ml of moisture per day.
This means that if your bathroom is bigger than average-sized bathrooms, it might not be a great option for you.
Another noticeable drawback is that the machine dehumidifies a space very passively, and the tank collects moisture at a snail’s pace. The chances are that you won’t have to drain the tank for up to 2-3 weeks, even in areas with a high humidity level, which is simply a sign that the product isn’t really doing a great job.
Putting aside the few drawbacks, the Hysure Direct will impress with its ultra-quiet Peltier technology that makes the machine incredibly quiet – almost noiseless.
Since this special technology doesn’t use a compressor, the noise produced by the motor is always below 33dB, which might make it the best dehumidifier for bathroom use if you really value your peace and quiet.
Additionally, it features an ‘energy-saving’ function – this makes the dehumidifier highly eco-friendly, energy-efficient as well as cost-efficient in the long run.
This unit, however, does not appear to have an Energy Star rating.
So what do you need to know about the second-best small dehumidifier in our roundup?
If you wish to buy this dehumidifier, do it only if you have small to standard-sized bathrooms.
This is because the bigger the bathroom, the more humidity there will be, and the more time it will take for the machine to collect moisture.
However, other than that, it is quite like the other dehumidifiers with almost the same functions and features.
LONOVE Portable Small Dehumidifier
The LONOVE Dehumidifier is the next product to be featured in our bathroom dehumidifier reviews and our overall fight against bathroom mold and dampness.
This is a wonderful product for your bathroom, where it aims to create moisture-free air, stop damp patches from appearing on your walls, and keep mold from growing.
This dehumidifier for bathrooms is extremely convenient and easy to use where all you need to do is take the tank out every time it is full, empty it into the sink, and then put it back in its place.
It has an auto shut-off function that further makes things easy by indicating through a yellow light that the tank has become full and needs to be emptied.
Furthermore, the machine is super impressive in terms of speed and takes just a few minutes to remove all the moisture from the air each time that you shower in the bathroom.
Overall this dehumidifier is a solid perform except for one minor drawback: it doesn’t have an auto-restart function.
That means every time there’s a power outage or power failure, you will have to manually switch it on again.
So, if you live in an area where there’s occasional power breakdown, you might not enjoy owning this otherwise great dehumidifier.
You should also consider its coverage area, and that’s a maximum of 1200 cubic feet or just over 112-sq feet, at a rate of 350ml of moisture per day.
Which really only makes it suitable for a medium or small bathroom – it lacks the capacity for anything else.
A standout feature of this dehumidifier is how unbelievably quiet it is. It can be so silent sometimes that you might even end up forgetting that there’s a dehumidifier sitting inside your bathroom.
Another impressive feature is the ‘one-button control’ function that just requires you to switch it ON or OFF as per your needs. This ultimately provides you with a hassle-free experience without having to follow any tedious and elaborate steps in order to get the machine running.
There are also two air inlets on this machine, one at the back and the other in the front. These inlets promote increased efficiency in terms of removing all the excess moisture from the air.
There’s no doubt that this is a worthy bathroom dehumidifier, one without any obvious flaws or downsides. From effective de-humidification to increased speed to creating a healthy environment, this product checks all the boxes.
It’s also super compact, lightweight, and easy to use, all of which make it ideal to have in bathrooms.
Which makes it a strong contender for the title of best dehumidifier for bathroom purposes.
Dehumidifier Buyers Guide
Knowledge is power.
And this is especially true when it comes to buying household consumer goods like a bathroom dehumidifier.
Basically, the more you know about dehumidifiers, the more informed a purchasing decision you can make.
It also prevents you from buying a model that you’ll have to return, or replace in several month’s time
That’s why we created this buying guide for you.
Types of dehumidifiers
Dehumidifiers all perform the same basic function – removing moisture from the air, reducing the humidity levels in a large, medium, or small bathroom.
But how they go about doing that varies from one model to the next.
So it’s important to understand the different types of dehumidifiers you can purchase.
- Heat pump – this type of dehumidifier uses a powered fan to passes moist air over a heat exchange coil, which forces the water to condensate i.e. turn into droplets. These droplets are then passed to the collection tank.
- Ventilator – these devices also use a fan, but instead of condensing the water, they simply use the fan to pump moisture-filled air outside. The mechanism used here is similar to that found in a vented clothes drier.
- Desiccant – these dehumidifiers usually a cartridge filled with a water-absorbent hydrophilic chemical. This basically captures moisture and stores it in a gel, or similar substance. Once full, you’ll need to replace the cartridge. Some desiccant dehumidifiers also feature a water collection tank, but only on more expensive bathroom dehumidifier units.
Bathrooms come in different shapes and sizes, from the compact types found in apartments, to bathrooms that are bigger than some apartments.
This means your dehumidifier needs to be bought with your bathroom’s square footage in mind and the average level of humidity in that room.
Basically, don’t expect a dehumidifier with a 250-sq ft capacity to be able to deal with 500-sq ft worth of moisture.
You’ll just burn the motor out.
A dehumidifier’s water tank capacity in this regard is typically measured in either pints or milliliters (ml).
But some measure this in ounces, just to further confuse you.
How much capacity do you need a dehumidifier to have?
As a guideline, bathrooms measuring 300 square feet, with a 60% humidity level, will require a dehumidifier with a 25-pint water tank capacity.
So you should use that as your baseline.
Bathroom dehumidifiers consume more energy than most other household products.
That’s why modern models come with an Energy Star rating which measures both their energy consumption and how many liters of water they can remove from your bathroom per hour.
So, the higher the energy factor – which should be at least 2.0 – the more efficient your bathroom dehumidifier will be i.e. lower power consumption.
Also, the bigger the dehumidifier the more energy efficient it tends to be i.e. removing more moisture for every kilowatt of power used.
Most modern dehumidifiers come with an Energy Star rating but always do your due diligence here.
Anything with moving parts is capable of making a whole lot of noise, so dehumidifiers are no different in that regard.
In fact, it’s become such an issue that many manufacturers are creating bathroom dehumidifier models with either a silent mode or with built-in “quiet operation”, usually based on Peltier technology.
You might not notice the noise coming from your dehumidifier while taking a shower.
But you definitely will if you’re trying to enjoy a relaxing bath.
A simple rule of thumb here is that smaller dehumidifiers tend to run that bit quieter.
It’s also worth noting that models with a top exhaust tend to be around 10dB louder than models with a side exhaust.
Continuous drain option
When the water collection container in your dehumidifier is full the device should auto shut off.
But the thing is you’ll still have to manually empty the container, replace it, and then get the dehumidifier running again.
A continuous drain option means a small attached hose will empty the water tank without you having to do anything.
Is there a downside here?
Yes, because the continuous drain hose will need to be situated within reach of an outlet drain, or you’ll have to fit a new drain to accommodate it.
Never, ever assume that you can eyeball the physical dimensions of something like a dehumidifier, and assume it will fit neatly into your bathroom.
That’s why carpenters always, “…measure twice and cut once”.
And, yes, you can roll some models of dehumidifier into and out of your bathroom…but that’s only if you can get it past the bathroom door.
So measure the intended spot in your bathroom for your dehumidifier.
But also make note of how much it weighs.
It might be described as “portable”, but so is a grand piano if you have six people lifting it.
Plus, the weight can almost double if and when your dehumidifier is loaded down with 75-pints of captured water.
It should go without saying that you should establish a budget before you go shopping for a dehumidifier.
And then stick to it like glue.
Because this will prevent you from being struck down with a case of SOS (Shiny Object Syndrome) before being charmed by a salesperson into buying a model that’s bigger than you need.
While also costing several hundred dollars more than you had intended to spend.
The good news is that you can get dehumidifiers for as little as $50, but buying the cheapest model of anything is rarely a good idea.
Especially when you’re trying to prevent mold and mildew from accumulating in your bathroom.
The amount of warranty coverage for a dehumidifier varies from a minimum of 1-year to a maximum of 5-years.
And it’s not always the most expensive models that come with the longest warranty.
Even though it really should be the case that the “best” dehumidifiers have the longest coverage period.
But that isn’t the world we live in.
So, if you want complete peace of mind, you will need to consider purchasing an extended warranty.
Don’t worry the online store/salesperson is going to try to sell you one anyway.
Bathroom Dehumidifier FAQs
Here are some commonly asked questions about dehumidifiers for bathroom, their effectiveness, where to place them, how to maintain them, etc.
What Are the Average Humidity Levels in the Bathroom?
The moisture level typically depends on where you live and the external environmental temperatures. However, the average humidity levels in a bathroom will be anywhere from 40% to 60%.
Bathrooms, in particular, tend to have the highest moisture level of any room in a home because of their basic function – people bathe there, so steam is created and condenses against cold surfaces it comes in contact with.
Where should a dehumidifier be placed in the bathroom?
A vented dehumidifier will obviously need to be located near an open exterior window, or connected to an external vent.
Other dehumidifiers should be situated towards the center of the room, but obviously not in close proximity to your bath or shower.
Wherever possible, keep your dehumidifier away from direct contact with walls or any fabrics.
How often should I empty the water reservoir?
This will depend on the type of dehumidifier you own.
A model with a continuous drain option will never need to have its water tank emptied – this happens automatically.
Heat pump/refrigerant models need to be emptied when their tank is full – a sure sign of this is that your dehumidifier automatically shut itself off.
Desiccant dehumidifiers, on the other hand, may or may not need their water reservoir emptied. That’s because some desiccant models use a gel cartridge that is simply replaced, while other models use a combination of a desiccant gel and a water tank.
Is it safe to leave my dehumidifier on while taking a shower?
It’s completely safe to leave your dehumidifier on while taking a shower as long as the device itself is not exposed to water or water splashes.
Leaving your dehumidifier on while taking a bath or shower is actually one of the best ways to have it work at peak efficiency – it’s actively removing moisture before it can even condense. This should dramatically reduce the amount of mold and mildew and condensation on walls or windows once you’ve finished bathing.
What are the benefits of using a dehumidifier?
The primary benefit of using a dehumidifier is a reduction of dampness in your bathroom. This then results in less mold and mildew forming, so your bathroom will also look and smell cleaner.
An additional fringe benefit is the prevention of damp patches appearing on the walls or ceiling of your bathroom. Dehumidifiers, however, do not purify the air in a room, contrary to the claims made on other blogs.
How long should a dehumidifier last?
Under normal circumstances, your dehumidifier should last as long as the initial warranty on the product i.e. 1-year.
Excessive use of a dehumidifier can shorten its overall lifespan, especially if the product is slightly smaller than it should be for the coverage required.
Should I close my bathroom vent when running the dehumidifier?
There’s no need to keep your bathroom vent open when using a dehumidifier but you can do so if you wish.
Just remember that you’re doubling up on energy consumption by running the dehumidifier and extractor fan at the same time.
So there’s little point in buying a product that’s Energy Star certified if you’re going to waste electricity running it when you don’t need to.
Dehumidifiers are one of the most efficient and affordable ways for getting rid of humidity in your bathroom.
One small investment means saying goodbye to mold and mildew…and even those funky smells that seem to linger forever.
