Do you need ventilation in a bathroom?

A Bathroom Fan Is Good for Your Health and Wealth! Bathroom ventilation is almost always required for any home, whether the ventilation is coming from a window or a fan. Bathrooms trap moisture and steam inside them, which not only causes mold, mildew and unpleasant smells; they also create unhealthy conditions that can lead to health problems. By installing bathroom exhaust fans, you can prevent many of these problems. To add value to your home, make sure to install bathroom exhaust fans when first building or remodeling. Not only will this make your home more attractive during showings, it will also be safer when your family lives there.
