A bathroom exhaust fan may not be the most glamorous part of a renovation, but it’s one of the most important. Proper ventilation prevents mold growth, protects your walls and ceiling from moisture damage, and keeps the air fresh. 🚿💨
So, how do you choose the right exhaust fan for your bathroom? What features should you look for? How much does it cost? Let’s dive into the essentials.
❓ Why Do You Need a Bathroom Exhaust Fan?
Whether you’re taking a steamy shower or running hot water in the sink, your bathroom fills with humidity fast. Without a fan, that moisture has nowhere to go — and that’s where problems start:
-
🦠 Mold and mildew growth
-
🧱 Peeling paint and damaged drywall
-
🪞 Fogged-up mirrors
-
🧴 Musty smells and poor air quality
-
💸 Long-term structural damage
📍 In Chicago and across Illinois, building codes often require a properly vented exhaust fan in bathrooms without operable windows.
📏 How to Choose the Right Size Fan (CFM)
Bathroom fans are rated by CFM (cubic feet per minute), which measures how much air the fan can move. The larger your bathroom, the higher the CFM you’ll need.
💡 General rule:
1 CFM per square foot of bathroom space
(e.g., 70 sq. ft. bathroom = 70 CFM fan)
| Bathroom Size | Recommended CFM |
|---|---|
| Up to 50 sq. ft. | 50 CFM |
| 50–75 sq. ft. | 70 CFM |
| 75–100 sq. ft. | 90–100 CFM |
| Over 100 sq. ft. | 100–150+ CFM |
🧰 For bathrooms with separate tub and shower zones, consider additional airflow or dual fans.
🔇 Noise Level: How Quiet Should It Be?
Exhaust fans also have a noise rating, measured in sones. The lower the sone rating, the quieter the fan.
| Sone Rating | Noise Level |
|---|---|
| 0.5 – 1.0 | Very quiet (whisper-like) |
| 1.5 – 2.0 | Moderate |
| 3.0+ | Loud |
🛁 If you want a peaceful spa-like experience, go for a low-sone fan.
🌟 Features to Consider When Choosing a Bathroom Fan
Modern fans do more than just remove moisture. Depending on your budget and needs, consider these useful features:
-
💡 Light integration – Fan and LED light combo for small bathrooms
-
🌡️ Humidity sensors – Auto on/off based on moisture levels
-
⏱️ Timers – Prevents the fan from running too long
-
🛏️ Night lights – Soft glow for nighttime use
-
🧠 Smart controls – Connect via Wi-Fi or voice assistants
-
🔥 Heaters – Built-in fan heaters for added warmth in winter
🛠️ Types of Bathroom Exhaust Fans
There are several fan installation styles — the right one depends on your ceiling type, attic space, and remodeling plan.
-
Ceiling-mounted fans – Most common, vent air through attic
-
Wall-mounted fans – For homes without attic access
-
Inline/remote fans – Quieter, motor located elsewhere
-
