A toilet ventilation apparatus which can either be attached to an existing toilet in a structure as an after market product or manufactured in combination with a toilet. The toilet ventilator draws odors directly from the toilet bowl through an intake duct and exhaust manifold through at least one connector duct into a heat resistant draft box with said odor being expelled through an exhaust pipe into an outside environment. The toilet ventilator accomplishes this by incorporating the physics law of rising heat in order to create a draft to draw toilet bowl odors up and out. A motion detector switches on the heat source, possibly a light bulb, and a time delay keeps the heat source on and the apparatus functioning for a predetermined period of time. A draft could also be created by connecting to and utilizing the hot air in an attic. The exhaust manifold fits under the back of the toilet seat and rests under the toilet tank with spacers for added space and support of the tank. A gasket is disposed within the toilet's central opening which is centered within the manifold opening in order to prevent water leakage when it is transferred from tank to bowl via the openings and gasket. A seal can be attached to the underside of the toilet lid to further prevent the escape of odors not drawn in by the exhaust manifold. The draft box, preferably made of heat resistant sheet metal, can be placed either within an adjacent wall or above the toilet tank and perhaps housed in a cabinet for aesthetics. The exhaust pipe can vent either to the outside, within the adjacent wall or to the attic.
