Bathrooms can feel like muggy tropical rain forests after you shower, and this can be a bigger issue than many people think. That humid air can affect your home’s comfort and air quality. Here are several reasons why bathroom ventilation should be approached as a necessity instead of just a luxury.
Mold and Mildew
The damp environment of a bathroom offers a great space for mold and mildew. If the excess moisture from bathing isn’t removed, you will soon see and smell the effects of this in terms of musty mold odor and mildew stains.
Opening the bathroom door might seem like an easy solution. However, this isn’t an optimal ventilation solution because it lets that moisture into the rest of the home to raise the overall humidity. This decreases indoor air quality by increasing the likelihood of mold and dust mites, which thrive in humid environments. Anyone sensitive to these common allergens will suffer.
Excess humidity also makes a hot day feel less bearable and makes the air feel sticky and unpleasant.
If you live in an older home, the bathroom ventilation system that came with the house could be doing more harm than good and you should schedule an inspection. Exhaust fans in these homes were often designed to vent humid air into the attic or between ceiling joists. This easily leads to mold in these areas, which can spread throughout the home. Installing a new bathroom ventilation system is in order if the current one does not exhaust the humid air outdoors.
In addition, you should have a ventilation system that moves air at the correct rate. This is determined by the size of the bathroom and, sometimes, the number of toilets, showers and other water features. For example, most small bathrooms can get by with a single ventilation fan that can move around 40 cubic feet of air per minute. The larger the bathroom and the more water fixtures you have, the more powerful ventilation you will need.
