Abstract: Apparatus for venting odors from the toilet bowl by using a fan installed on one side of the toilet bowl. The odors are discharged under the toilet in the drain pipe through an appropriate extension ring designed to allow transit of discharged air. Easy installation of the mechanism requires only unbolting the toilet from the floor, placing the extension ring, base extension board and a new wax ring on the drainage flange, rebolting the toilet in place and making the connection to the fan.
