Is a Bathroom Dehumidifier Right for You?

Dehumidifiers regulate any humidity that may be lingering in the air. Too much humidity can cause numerous problems in your home, and for your health. Something we explore in more detail in our dedicated guide. 

Excess moisture in the air causes dust mites, mould, and hazardous toxins that can be harmful to your health and well-being. 

Humidity can worsen any respiratory illnesses, such as asthma, and can cause allergies to accelerate. If you have noticed during the warmer months that your allergies will not go away, then this is most likely the cause.

This is especially if you notice that your bathroom feels muggy, even with the fan running. Small living spaces such as bathrooms with limited ventilation, are common areas where moisture can build up, even in dry climates.

The Benefits of a Bathroom Dehumidifier

There are amazing benefits to owning a dehumidifier, and here are a few reasons why you should consider investing in one for your home. 

Quiet Running. The first reason is that dehumidifiers are typically quiet, making it easy to run without disturbing anyone who might be sensitive to sound. 

Natural Cooling. Another good reason to own a dehumidifier is that if you do not have a central air conditioning unit in your home (not too common in the UK), dehumidifiers can cool down a room without needing to invest in a cooling unit that will increase your energy bills. 

Energy Efficiency. Leading on from the previous advantage, dehumidifiers are also energy-efficient, which means you won’t be spending too much to keep the unit running. This makes them more environmentally friendly and reduces your carbon footprint. 

Odour Reduction. Dehumidifiers can reduce any odours that might be lingering in your home if they have a carbon filter. Bathrooms without ventilation can cause a musky, mildew smell. Which can be bothersome to those that are smell-sensitive. 

Mould Reduction. These devices also reduce the possibility of mould spores growing on your ceiling, walls and tile grout. Mould spores are extremely toxic, and thrive in high humidity, so a dehumidifier is useful for removing those dangerous toxins. 

Clearer Skin. A dehumidifier can also help reduce acne in teens. An overabundance of moisture in the air can cause skin to break out from oil in the skin over-producing. Not only that, dust mites, and any other hazardous toxins in the air can cause skin to become irritated.

Do I Need a Bathroom Dehumidifier?

Dehumidifiers are perfect investments for your home, depending on the climate levels. If you are not sure if you actually need one, a method of determining whether or not one is needed is by purchasing a hygrometer. 

You want to aim to have at least 30% to 50% levels of humidity in your bathroom, and a hygrometer tells you exactly what you are looking for. 

If your humidity levels are above 50%, it is definitely needed. If the humidity levels fall below 30%, you will need a humidifier. 

Most modern-day dehumidifiers come with a built-in hygrometer. That way, you can determine whether or not you need to be running the dehumidifier.

A good tip is never close the doors on your shower after use, allowing the air to circulate and avoid mould build up.

How to Choose the Perfect Bathroom Dehumidifier

There are a variety of different options that are available when it comes to dehumidifiers. Whichever option you choose also needs to align with the situation you are dealing with. 

This includes the size of the space you are working with, and the levels of humidity you are experiencing. 

Space. With a bathroom generally being on the small size compared to other rooms in the home, you should, in most cases get away with a bathroom dehumidifier with a 15L capacity, this would suit any 12 x 15 (feet) bathroom for example.

Budget. Of course, budget plays a big role for most of, but you can expect to pay anything from £40 for a reasonable bathroom dehumidifier.

Automatic Shutdown. You don’t always know when the tank is full, or you might not be home. Having a model that shuts down when the water tank capacity is reached is important for your safety as well as the functionality and durability of the dehumidifier.

Most models featured here have this feature.

Additional Features. Some units on the market are wall mountable, so your pets or kids don’t knock the unit over. There are also dehumidifiers with a continuous drainage pipe that can easily be connected to a drain or go out your bathroom window. 

Some models do offer remote control use, so you don’t have to be physically next to the unit in order to turn it off or adjust the settings. Some even come with smartphone control.


Should a bathroom dehumidifier run constantly?

The answer to this question is no, a dehumidifier does not need to run constantly in order to work efficiently. You should only run your dehumidifier when the humidity level in your bathroom runs above 50%. 

Is it ok to run a bathroom dehumidifier overnight?

Yes, it is safe and ok to run your dehumidifier overnight unattended. Most models available on the market have an automatic shut off option, so you will not wake up the next morning to find water overflowing onto your floor. 

Another reason why it is okay to run your dehumidifier overnight is that dehumidifiers are usually noise-resistant. You will not have to worry about your unit making too much noise, causing difficulty trying to sleep.

How often should I have to empty my bathroom dehumidifier?

Emptying your bathroom dehumidifier’s water basin is all determined on the situation you are dealing with. If your humidity levels are above 50% and your water tank capacity is smaller, you might need to drain the container twice a day. 

Larger units might be every two days. It might be more beneficial for you to buy a unit that includes a drainage pipe attachment, that way you can stick it in the bathtub or out a window, and not have to worry about having to drain it.

Should you open your windows when using a bathroom dehumidifier?

The answer to this one is no, you should not open your windows when using a dehumidifier. Depending on the climate outdoors, this will cause your unit to start pulling in additional moisture from the air. 

This results in your needing to drain your unit’s basin more frequently, causing the dehumidifier to become less efficient. By opening a window, you are letting more humidity into the house. A dehumidifier cannot control outdoor temperatures.

Should I run a fan with a dehumidifier?

Yes, it is perfectly fine to run a fan while your dehumidifier is working. It will have no impact on how your dehumidifier runs or the humidity level in the room.

What should I set my bathroom dehumidifier’s settings to?

The optimal relative humidity level is between 30% and 50%. If the humidity is higher than that, it can breed dust mites, mildew, and mould, as well as trigger allergies and asthma.

Do bathroom dehumidifiers work in a cold room?

Most dehumidifiers operate best at normal room temperatures. Colder temperatures might cause the unit to stop functioning correctly. This is due to humidity levels being too low. 

What other steps can I take to reduce the humidity in my bathroom?

You can help reduce humidity in the bathroom by following these steps: 

  • Ventilation covering cracks in windows, doors, or any other areas where moisture might be leaking in can overall help reduce the humidity that you are feeling in your home
  • Fixing leaky pipes. Fixing any leaks in your bathroom will help reduce any moisture from entering the environment. Leaky pipes can cause mould to grow, which can cause respiratory issues. 
  • Install Exhaust Fans – Places like the bathroom, acquire a lot of humidity. Whether showering or using the bath, especially with multiple people in the house, all adds dampness to the air. Installing an exhaust fan to an exterior wall can help suck out much of the moisture.
  • Never close the door on the shower after use as mentioned earlier in the article. Keep it ventilated.

Does a heated towel rail reduce humidity?

Yes, central heating by way of a heated towel rail does reduce humidity. Central heating warms up the air of a house so it reduces its relative humidity, but as it circulates around the bathroom and cools down its relative humidity increases although the absolute amount of moisture in the air stays the same.

Can a bathroom dehumidifier dehydrate you?

The answer to this is no, a bathroom dehumidifier will not dehydrate you. They are only designed to absorb moisture from the air. If you are experiencing dehydration, it is more than likely due to a lack of water, dry air, climate, a food allergy, or illnesses.
