The short answer is, yes, you do need an exhaust fan in your bathroom. Because bathroom appliances create so much moisture, these spaces are prime targets for household water damage. Over time, moisture seeps into the walls and may cause structural issues, mildew, or mold growth. We will work with you, though, to find an exhaust fan that works with your existing design, so you get both the look and functionality you need at the end of your bathroom improvement experience.
