Various aspects of this disclosure relate to toilet systems that include compositions to inhibit wastewater from freezing in a waste tank of a toilet. A first fluid treatment composition comprises a salt that is introduced into the waste tank. A second fluid treatment composition is a solid composite that also comprises a salt and that is introduced into a urinal in fluid communication with the waste tank.

Transportable unit for forming a straight parallelepiped-shaped residential space, provided with a bottom and a covering, and upright walls extending in between them, which walls can be converted between aparticularly retracted-transport position and aparticularly extended-operational position, in which the unit has a larger height, wherein the unit is equipped as a sanitary unit having a series of toilet bowls, urinals and/or showers.

A portable restroom includes an automatic continuous flushing feature and a touchless flush request sensor. An automatic light provides welcome lighting in darker locations. An electric fan increases ventilation and reduces odor and temperature in the restroom. Sensors monitor various levels and usage of consumables. A processor monitors the sensed data and wirelessly alerts a service provider when the restroom needs service. A flushing bowl is placed in the commode opening to hide the waste within the tank. The flushing bowl includes a relatively small opening in a forward portion of the inner bowl surface for waste to pass through. A spray nozzle for directing water over the interior of the bowl is provided to minimize the chance that waste sticks to the inner bowl.

A portable toilet has a seat and a waste receptacle mounted to a frame to allow use as a toilet in conventional fashion. The waste receptacle is pivotally mounted to the frame to allow the forward end of the receptacle to be lifted to spill the contents into a conventional building toilet. A pour spout extends from a rearward end of the waste receptacle. The frame, seat and the waste receptacle are configured to place the waste receptacle at a proper height for personal use and for pivoting the waste receptacle to spill the contents thereof into the conventional building toilet. A water flush system is provided which includes a water supply and nozzles mounted to the waste receptacle for cleaning the contents there-from. The water supply may be provided by connecting to a building water faucet, or by mounting a tank and pump to the portable toilet.

Display cabinet of hydrosanitary devices and/or associated products configured to contain and keep a first hydrosanitary device and/or associated product in a first predefined position and/or spatial orientation and including a body having a first portion and a second portion reciprocally movable to define at least: an opened configuration of said body, wherein said first hydrosanitary device and/or associated product results visible and/or accessible from outside the body, and a closed configuration of said body, alternative to the opened configuration, wherein said first hydrosanitary device and/or associated product results enclosed inside said body and/or not visible, and/or inaccessible, from outside the body; said display cabinet being configured to be transportable along with said first hydrosanitary device and to be stably positionable on a resting surface in an exhibition environment; said body being configured to simulate an application context of said first hydrosanitary device and/or associated product.

A triangular shaped portable toilet. Three toilet sides are connected to a triangular shaped toilet floor. A door is connected via hinges to one of the toilet sides. A triangular shaped roof is connected to the three toilet sides. A waste holding tank is connected to the floor and to two of the toilet sides. In a preferred embodiment, multiple portable toilets are arranged side-by-side to maximize space efficiency.

An autonomous toilet may include a waste receptacle having a receptacle opening, a seat extending at least partially around the receptacle opening, the seat being configured to support a user of the autonomous toilet, a plurality of driven wheels configured to urge the autonomous toilet across a surface, one or more sensors configured to sense one or more conditions of a surrounding environment, and a controller communicatively coupled to the one or more sensors and the plurality of driven wheels.
