A portable toilet particularly suited to be a roll-out toilet positions a toilet with its holding tank at a rear wall, a sink at an opposed front wall, a urinal on one of the side walls and an access door through the opposing sidewall to provide access to the enclosure formed by the, front, rear and side walls. By connecting the drain from the sink to the urinal so that the water draining from the sink must pass through the urinal and then pass from the urinal to a toilet holding tank via a drain line connecting the urinal to a toilet holding tank the sink drain water is collected and will tend to wash and thereby clean the urinal.

There is provided a sanitary washing device. The sanitary washing device includes a wash water heating part, a jetting nozzle, and a controller. The wash water heating part includes a first heater and a second heater. A resistance value of the second heater is higher than a resistance value of the first heater. The wash water heating part heats wash water supplied from a water supply source by only the first heater and the second heater. The jetting nozzle jets the wash water supplied via the wash water heating part. The controller controls a power supplied to the first heater and the second heater.

A method of removing wastewater contained in a water retention tank of a grey-water management system for an aircraft toilet. The method removes the wastewater via a diaphragm pump having an undulating diaphragm. The diaphragm pump includes an inlet pipe connected to the retention tank, the diaphragm of the pump is actuated by electromagnetic or magnetic actuation so as to remove wastewater present in the retention tank through the inlet pipe of the pump to an outlet pipe of the pump.

A cold bathing water to toilet diverting apparatus includes a diverter that is configured to be fluidly couplable to a bathing water conduit. The diverter is positionable between a shut off valve and a spout each fluidly coupled to the bathing water conduit. An outlet conduit is fluidly coupled to the diverter. The diverter diverts water from the bathing water conduit and into the outlet conduit when the diverter detects water in the diverter having a temperature less than a threshold temperature. A storage tank is fluidly coupled to the outlet conduit to receive water from the diverter. An auxiliary conduit is fluidly coupled to the storage tank and is configured to be fluidly coupled to a toilet's water tank to allow the storage tank to supply water to the water tank through the auxiliary conduit.
