Dehumidify Your Bathroom in 10 Easy Steps

Home Health Living has compiled a list of 10 handy ways to cut moisture and dehumidify your bathroom, and we look at what causes condensation.

A relaxing hot bath at the end of the day is a great cure for everyday stress, but our bathroom habits could be doing more harm than good.

Bathroom Humidity

Humidity in the bathroom is caused by condensation and can lead to various problems: promoting bacteria and mold growth, causing paint or wallpaper to peel and potential slippery hazards. The problem is worse for bathrooms without adequate ventilation, especially those without windows or fans. Bathroom mold and grime can be a pain in the neck to clean- not to mention a health hazard, being a common trigger for asthma and allergic reactions. It’s important to therefore dehumidify your bathroom to prevent these problems from occurring.

What Causes Condensation

Condensation occurs when warm, moist air (ie. steam) comes into contact with a cold surface, typically while the bath or shower is being used. The cold surfaces in a bathroom cause the warm air to condense into droplets of water. In a bathroom, typical cold surfaces include the window, walls, ceiling and mirror.

How To Dehumidify Your Bathroom

With a few easy steps you can reduce the moisture and dehumidify your bathroom.

1. Windows
Open any windows in the bathroom after you have a bath/shower. If it isn’t too cold, leave a window open while you are in the shower.

2. Use a dehumidifier
A dehumidifier works by drawing in moist air, removing the moisture, and then blowing out the dry air back into the room. The moisture is retained in the dehumidifier to be emptied. This is an effective way to reduce moisture in the bathroom.

3. Fan
If you have a fan, switch it on after your bath/shower.

4. Heater
If you have heating in your home or even in the bathroom, or you have an electric towel rail, turn it on before using the bath/shower. By heating up the bathroom, the walls and mirror will be warmer, which will reduce the likelihood or amount of condensation.

We recommend the following best-selling heated towel rail:

Amba RWH-CB Radiant Hardwired Curved Towel Warmer, Brushed

5. Damp Towels and Mats
Remove any damp towels and mats from the bathroom and let them dry outside.

6. Double Glazed Windows
Single glazed windows tend to be colder and so create more condensation. This can be reduced by double glazing your bathroom window.

7. Defogging Mirrors
Condensation on the bathroom mirror adds more moisture to the room. You can either wipe your mirror dry with a cloth, or you can purchase a mirror with a built-in defogger. This keeps the mirror warm and prevents condensation from occurring. If you can’t buy a new mirror with a built-in defogger, we recommend purchasing the defogger separately, such as this one:

Radimo MD16x24 Mirror Defogger, 16″ x 24″

8. Wiping
Wipe down any water on the floor, walls, vanity and shower with an old towel, to keep the room as dry as possible.

9. Time Your Showers
Think about giving up your long hot shower/bath. By reducing the time you spend in the shower, this will reduce condensation.

10. Filling Your Bath
When filling your bath, run the cold water first and then the hot water to reduce steam.

These easy steps will help you dehumidify your bathroom. By focusing your efforts on increasing ventilation, maintaining an adequate temperature and making a few adjustments to your bathroom habits, you will reduce the moisture levels in your bathroom and prevent the common problems associated with bathroom humidity and condensation.
