A ventilated toilet includes a bowl with a rim including a rim conduit with a plurality of flush apertures that open to the bowl. A drain conduit communicates with a waste outlet of the bowl and includes a stack outlet for communicating with an associated waste stack. A trap is located in the drain conduit between the waste outlet of the bowl and the stack outlet of the drain conduit for containing liquid that blocks airflow through said drain conduit. A neck is located adjacent the rim of the bowl and includes a neck conduit in communication with the rim conduit. A water tank is connected to the neck and includes an internal space for holding water that is in communication with the neck conduit. A lid covers an open upper end of the tank. A flush valve is located in the tank and selectively opens to allow flow of water from the internal space of the tank to the neck conduit. An overflow tube is in communication with the neck conduit and includes an open upper end that is located above a water level of the internal space of the tank. An exhaust blower includes a blower inlet and a blower outlet. A blower inlet conduit connects the blower inlet to the internal space of said tank, and the blower inlet conduit includes an open upper end that is located above the water level such that the open upper end of the blower conduit is spaced-apart from the open upper end of the overflow tube. The blower outlet is in communication with the drain conduit downstream from the trap between the trap and the stack outlet. A check valve is located between the blower outlet and the drain conduit for preventing odorous air from flowing upstream into the blower outlet, wherein said check valve is adapted to selectively open when said exhaust blower is activated.
