Abstract: Provided are toilet ventilation systems. A toilet ventilation system may use an air conduit to facilitate removal of air from a toilet bowl into a toilet tank via an overflow tube. The air conduit may connect the toilet tank and a ventilation fan. The toilet ventilation system may include a ventilation valve coupled to the air conduit and configured to open into a room environment. The ventilation valve may be coupled to a flush handle via a ventilation valve connector. Engaging the flush handle may open the ventilation valve into the room environment. The toilet ventilation system may also include a drainage connector configured to couple the flush handle to the overflow tube that may be connected to the toilet bowl via a drainage tube.
