The apparatus comprises a toilet seat cover having independent fluid and gas conduits, a toilet seat and a runoff pan means, a control unit box and means for connecting the fluid and gas supply lines from the control unit box to said toilet seat cover. The toilet seat and the toilet seat cover and the runoff pan are pivotally connected by a hinge means and can independently move to an up or down position. Upon closing, toilet seat cover means are provided for automatically initiating the washing and drying cycles after each use. The control box unit further comprises an electric process unit including means to control and adjust the starting and finishing time of washing and drying cycles. The toilet system is sealed during the washing cycle to avoid splashing the fluid out of the toilet system.
