Abstract: A toilet bowl sanitizing apparatus for sanitizing water in the toilet bowl. The toilet bowl sanitizing apparatus includes a toilet bowl sanitizing apparatus for mounting in a toilet. The toilet has a tank with an interior for selectively holding flushing water and a fill valve for controlling water flow from a water supply to the tank. A lever coupled to a float controls the fill valve. An upstanding overflow container is mounted in the tank and empties into a tank outlet. A trickle conduit is in communication with the fill valve for squirting water into the overflow container. The tank outlet is in fluid connection with a toilet bowl. The apparatus comprises a container which has a first end, a second end and a substantially hollow peripheral extending wall therebetween. The first end of the container has an opening therein and the second end is closed. A cap is adapted for mounting over the opening in the container. An intake pipe brings water into the container.
