💧 WET BATHROOM WALLS AFTER A SHOWER? 🚿
Even with the exhaust fan running, excessive moisture on bathroom walls could indicate a ventilation problem!
We recently evaluated a bathroom with a 50 CFM exhaust fan that struggled to remove moisture during hot showers.
🔧 A few things to consider:
✅ Fan Size – Is your exhaust fan sized properly for the space?
✅ Ductwork – Undersized or restrictive ductwork can significantly reduce airflow, even with a larger fan.
✅ Makeup Air – Proper airflow into the bathroom is just as important as exhausting humid air.
✅ Run Time – Keep the fan running for 20–30 minutes after showering.
💡 The SKY Engineering Takeaway: Bigger isn’t always better! Proper fan sizing, duct design, and airflow are all essential for effective ventilation.
At SKY Engineering, we know that good HVAC design makes a difference, whether it’s a small residential bathroom or a large commercial facility!
