Bathroom Dehumidifier Buying Guide
Bathroom Coverage Area
The coverage area is how a dehumidifier can effectively extract moisture out in a room. The volume is measured in a few different ways, including square foot, cubic foot, or square meters outside of the United States.
Before purchasing a bathroom dehumidifier, it's essential to check the features and to get an estimate of the volume of your bathroom. To do this, you find the measurements for the length, width, and height. Then, you take the numbers and multiply them (L x W x H=V in cubic feet).
“ cubic measurements take all three dimensions into consideration. This will tell you the volume of a given area”
- Paul Bianchina, Contractor/Author 
Also make sure to get a dehumidifier for bathroom use that exceeds the volume of your room. If you purchase a dehumidifier that is too small or right at the size of your bathroom, it may not work efficiently enough to do the job.
The capacity will dictate how much water the best dehumidifier for bathroom use can hold before you have to clear it. The best dehumidifier for bathroom use will have one of those larger water tanks requiring you to need to empty it less frequently.
To figure out how often you would have to discard the contents of the container, look at the tank capacity rating for the dehumidifier you are considering. Then, look at the dehumidifying rate discussed below. So, for example, if a unit has a 20oz tank and removes moisture at a rate of 9oz of moisture per day, the container will require emptying every two days.
This number shows you how much moisture the dehumidifier can pull from the air in a room in one day. You would see this measured as oz per day, gallons in one day, or pints every 24 hours. To get an accurate understanding of how much humidity needs removal, you should use a hygrometer to measure the humidity level in your bathroom .
A hygrometer is an often inexpensive tool for effective measuring of humidity in a room. Using this tool, you can calculate the actual dehumidify rate needed to extract the excess moisture from your bathroom.
“Indoor air dehumidification can be used [to prevent mold], in which dehumidified air is circulated through a cooling coil, where water is condensed and drained.”
- Michal Krzyzanowski, World Health Organization Europe 
Self Draining Capabilities
The best dehumidifier for bathroom use is usually designed to provide self-draining capabilities. Usually, by way of a hose connecting to the water tank, which allows it to drain automatically rather than storing in the container.
If you plan on running the dehumidifier continuously throughout the day and night, this is an important feature as well. If not, you will have to monitor the container regularly and discard the water manually.
Size and Weight
Size and weight limitations will be highly subjective to your specific needs and what you like. If you have designed a small bathroom in your house but do not have a large space, the ideal unit is a more compact and small dehumidifier. Remember that a smaller unit will also mean a smaller water tank and generally a lower rate at which the unit can dehumidify a room.
Yes, it is safe to leave dehumidifiers operating while you shower so long as no electrical wires are exposed.
It would be best if you emptied the water tank of dehumidifiers when it becomes full. This will be different for every unit and will also depend on how much moisture is pulled from the air. It is ideal to look at the dehumidifying rate and the tank size to calculate how often you like to discard the tank's content. Also, consider looking for a continuous draining option that self drains.
The size of the dehumidifier you need for your bathroom will depend on the moisture level in the air and how large the room is. One of the first things to calculate is how much moisture needs removing using a hygrometer.
Next, calculate the volume of your bathroom. If you have one large bathroom, you have to remove more moisture from the air. If such is the case, you also need a larger bathroom dehumidifier to reduce humidity in the air. Look for Energy Star certified appliances for larger dehumidifiers to save on your energy bills .
Yes, dehumidifiers will help with mold in the bathroom. A bathroom mold forms due to excess moisture in the air, and it also surfaces on walls and wood. One portable dehumidifier will remove the excess moisture easily in rooms and improve ventilation. It will help in creating a less hospitable environment for mold and prevent mildew from forming. It will also enhance the quality of air in any room.
Some tips to decrease humidity levels in your bathroom include shorter and cooler showers and opening windows and doors to prevent steam from being trapped. For some people who have an exhaust fan in their bathroom, this can also help improve ventilation.
One of the few effective things you can also easily do is wiping down excess moisture on mirrors. Also, wipe down other surfaces after taking a shower is still essential to improve air quality. Doing these things, along with using a portable dehumidifier for bathrooms, will also help to keep moisture in check.
