Odor Removal: It helps to eliminate unpleasant odors, ensuring a fresh and comfortable environment.
Ventilation: A basement bathroom vent pipe facilitates the exchange of air, preventing stuffiness and ensuring adequate air circulation.

3	Drill a hole in the basement ceiling or exterior wall, using a hole saw that matches the diameter of your vent pipe.
