Automatic flushing, lid raising and seat raising arrangements for toilets include a tank top having optical sensors integral therewith so that standard flush tanks and tops may be used with only the tops being slightly altered to accommodate the optical sensors. The flushing arrangement is readily mountable on standard overflow pipes and provides automatic flushing while also allowing manual flushing. The lid and seat raising and lowering actuators are arranged in a single unit readily attachable to a standard toilet bowl using substantially standard lids and seats.
