To replace a bathroom ceiling fan, turn off the power at the circuit breaker. Remove the existing fan by unscrewing it from the ceiling and disconnecting the wiring. Install the new fan by following the manufacturer's instructions, securing it to the ceiling, and reconnecting the wiring. Restore power and test the new fan to ensure proper operation and airflow.

Replacing a bathroom ceiling fan improves ventilation and air circulation. Proper installation ensures effective operation and reduces moisture-related issues in the bathroom.
