Bathrooms are typically one of the most humid rooms in the house. And it’s no mystery why. The shower creates a huge amount of moisture each and every time it is run.
But unchecked humidity in the bathroom will eventually lead to mold growth.
And though mold in the shower is easy to see, it’s all the other mold growing in dark spaces as well as on your towels, toothbrushes, and other items in the bathroom that makes it so disgusting.
Not only disgusting, damaging.
Mold can do a huge amount of damage and in a very short time. Areas like window frames and drywall can experience mold rot very quickly when mold is left to increase.
If you have a bathroom that doesn’t have an exhaust fan or maybe it does but it just can’t keep up with the level of moisture and condensation that you seem to be experiencing,
There is an option that will help reduce the humidity in your bathroom and it’s one that doesn’t carry that high of a price tag.

What I’m talking about is a small bathroom dehumidifier.
Dehumidifiers work well in bathrooms. Not only does a dehumidifier easily reduce the moisture in the bathroom,
Being close to a sink or shower makes the maintenance of emptying a dehumidifier or running a continuous drain hose much easier.
Bathrooms in most houses generally do not come in over 40 square feet.
And the smallest portable compressor dehumidifiers typically cover around 250 square feet.
So a dehumidifier can keep the air in the bathroom very dry.
Will a dehumidifier keep mold from in the bathroom?
A dehumidifier will help keep mold from growing because moisture in the air is essential for mold to take root.
And that is exactly the point of a dehumidifier, to remove moisture from the air.
But If you want to eliminate the chances of mold growing in your bathroom, you will have to address other standing water issues on a regular basis as well as running a dehumidifier.
What is the best dehumidifier for a bathroom?
In our opinion the best bathroom dehumidifier is the Medea 1500.
It is not only small enough to completely dry out a bathroom, it is large enough to use in a laundry room, bedroom, or kitchen.
It also has a built-in pump and a washable air filter. A couple of things hard to find on a small bathroom dehumidifier.
Being such a small room, the bathroom actually has a few good options for what you might consider to be the best bathroom dehumidifier.
Desiccant Bathroom Dehumidifiers
Desiccant humidifiers come in small mountable units that can be placed on the wall out of the way.
They do not require the typical maintenance of emptying a dehumidifier. Nor do they have to have any type of pump or garden hose ran to them.
The only maintenance is that they are recharged once every couple of months.
These small bathroom dehumidifiers are perfect for helping dry out a medium to a small amount of humidity.
They are all so perfect for closets, pantries, and other small areas
The downside is there is no measurable way to reduce the humidity.
So they will require a separate hygrometer to actually keep tabs on the humidity level inside of the bathroom.

A small portable bathroom dehumidifier
A mini dehumidifier works exactly the same way as a full size portable dehumidifier.
The only difference is that it is much smaller and works in a smaller room.
And even though these dehumidifiers are small, they still can dry out the air in a room that is 250 average square feet.
That means you will not have any problems drying the air out in a room the size of a bathroom.
And it also means that you will have a great small dehumidifier to use in your laundry room, kitchen, or bedroom.
The benefit of using a traditional bathroom dehumidifier is that they or much more exact and can be set to reach a specific humidity level when desired.
They also have features like Auto shut off when the tank is full, and humidistats to shut the machine off when the desired relative humidity is reached.
There is maintenance involved in the form of emptying the bucket when it is required.
But there’s also the option of hooking a continuous drain line in order to avoid ever having to empty the machine.
But just like a humidifier, they have to be cleaned regularly to avoid mold and bacteria from taking root in them.

Q & A
What can happen if you have excess humidity in the bathroom? Mold, damage?
Having excess moisture in the bathroom can cause a lot of damage. Specifically mold damage.
When you’re having a problem with excessive moisture in the bathroom, you will eventually discover that you have mold growing.
And when it becomes visible in the shower, you can be sure that it has found a whole host of dark places to take root as well.
High unchecked humidity in the bathroom will eventually lead to mold feeding on your wood surfaces, window frames, baseboards, etc. and can lead to significant damage.
Other areas you may find mold growing:
- Ceiling tiles, wall tiles
- Carpet and rugs
- Gypsum board (drywall) and the insulation inside the walls. Drywall typically bows out when it’s full of moisture and the paper begins to peel.
Once mold has become a problem in the bathroom, the spores from the mold will be everywhere from your towels, toothbrushes, as well as your pillows and bedding if your bedroom is adjacent.
When do you need to use a bathroom dehumidifier? Winter, summer?
The summer months news typically when you find the higher levels of humidity outside and when you have the most problems controlling the humidity inside.
But humidity inside of the bathroom can be an issue in the winter also when the outside air is cold and it is coming in contact with the warm inside air via the window.
You have probably noticed condensation on your windows during the winter.
The condensation will lead to mold just as fast as any other type of moisture.
So controlling the humidity in the bathroom can be a all year endeavor
Where would you put a dehumidifier in the bathroom?
Finding the space in a bathroom for a dehumidifier is not the easiest thing to do, especially if you, like me, live in a house with a lot of females.
The ideal spot for a dehumidifier in a bathroom would be on an elevated spot on the sink countertop.
That way you could run a small hose to the sink from the dehumidifier and not have to continuously empty it.
The same concept would work well for the shower too. An elevated spot next to the shower would give you excellent access to either emptying the dehumidifier we’re running a continuous drain hose to the shower drain.
Desiccant dehumidifiers come in small portable units easily hung on the wall next to the shower.
Desiccant dehumidifiers do not extract nearly the amount of water as a traditional mini compressor humidifier, so using more than one in the bathroom is a good idea.
Does a bathroom dehumidifier use a lot of electricity?
The amount of electricity that a bathroom dehumidifier uses depends on the level of humidity and the runtime of the dehumidifier to extract the humidity everyday,
You can expect a small dehumidifier to use as much as 30 Watts and a larger dehumidifier to pull as much as 70 Watts.
How loud are bathroom dehumidifiers?
Bathrooms are pretty loud spots in my house, it’s not uncommon to hear the radio blasting, shower running, and hair dryer is going at the same time.
Dehumidifiers can be compared to the level of noise you would get from a window air conditioner. Around 65 db.
But the bathroom is not exactly in use as much as the living room or a bedroom.
What’s the difference between desiccant bathroom dehumidifiers and mini dehumidifiers?
Desiccant dehumidifiers absorb humidity much like a sponge. They also never have to be emptied or run with a continuous drain hose.
They are also much quieter.
Desiccant dehumidifiers for small spaces like bathrooms and closets, or easily mounted to the wall or hung from a hook.
You probably know “desiccants” as the little silica gel packets that come and everything from shoe boxes to keeping gerbil snacks fresh.
Desiccant dehumidifiers are the same concept in a much larger version.
Traditional compressor dehumidifiers extract moisture from the air exactly the way that a window air conditioner does. It pulls air in with a fan, drags it pass a series of condenser coils that capture the moisture and then releases the air back into the room dry.
A mini compressor dehumidifier can extract moisture from a room as big as 200 or even 300 square feet.
That’s much more then you will be able to achieve with a small desiccant dehumidifier.
But there is also maintenance to be considered with compressor dehumidifiers.
If you do not go the drainage hose method, you ‘ll have to empty the bucket for the dehumidifier to run.
And the potential of having standing water is much higher. Dehumidifiers must be cleaned often to avoid mold growing in the machine.
They can also be quite loud.
But One mini portable dehumidifier is big enough to use in the bathroom, bedroom, laundry room, and kitchen.
Will a dehumidifier soak up water?
A dehumidifier will make it easier for water to dry and is often used to help clothes to dry faster on hangers.
But it is primarily a device to remove moisture out of the air.
Although it will help considerably to reduce the capacity for mold to grow, it will not soak up standing water, nor will it wipe down or squeegee off shower walls, or condensated windows.
Bathroom dehumidifier versus an extractor fan
Installing a dehumidifier is as simple as plugging it in and turning it on. But you will have to empty the bucket on a continual basis and keep the machine clean.
Which to be fair is a much easier endeavor when you are next to a sink or a shower.
On the other hand, a humidity extractor fan just has to have a switch flipped on. No other maintenance involved.
But installing a humidity extractor fan will take much more than plugging it in.
It will require cutting a hole in the ceiling, and hardwiring it into your existing electrical grid.
Though the bathroom can be one of the most humid rooms in the house
Dehumidifiers are devices that can do a great job of remedying that problem.
Small dehumidifiers that you can benefit from using in your bathroom come in both desiccant and compressor type.
Desiccant dehumidifiers use chemicals to soak up moisture in the air. They are very inexpensive and work well for light to medium humidity.
They are also very safe and require very little maintenance. The only maintenance that you will have to keep up with using a desiccant dehumidifier is keeping it charged.
A small compressor type bathroom dehumidifier uses refrigerator cooling coils to condense the moisture in the air.
The water that is captured through the condensation process either goes into a bucket that has to be emptied or can be drained through a continuous drain line.
Compressor dehumidifiers can extract much more moisture out of the air then desiccant dehumidifiers are capable of.
Traditional bathroom dehumidifiers also I’m more likely to come with bells and whistles like built-in hygrometers, auto shut off when the tank is full, and auto defrost if the temperature is lower.
Desiccant dehumidifiers will require a separate hygrometer in order to be able to keep tabs on your relative humidity.
