A system and method for cleansing a cavity in a living body is disclosed. The system uses pressurized water from a plumbing system and directs a portion of that water into a douche pipe for cleaning the cavity. The system includes a shower attachment member that is configured to collect water from the plumbing. Also included is a douche pipe configured to direct the flow of water toward the opening of the cavity in a rearward axial direction so as to let the pressure of the water pull bacteria or infections directly to the opening for removal. The douche pipe includes at least one port that is oriented in a non-perpendicular orientation.
