A portable restroom includes an enclosed interior including a door, a waste tank, a commode disposed within the enclosed interior and coupled to the waste tank, a power source, a microprocessor coupled to the power source, a door sensor positioned to sense whether the door is open or closed, and a door lock sensor positioned to sense whether the door is locked or unlocked. Sensors can be provided to sense the closed status of the door and the status of the door lock. Additional sensors can monitor various levels and usage of consumables. The microprocessor monitors the sensed data and wirelessly alerts a service provider when the restroom needs service. A payment receiving means can be provided to the portable restroom and coupled to the microprocessor so that a user can provide payment for access to the portable restroom.

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.

A housing for a portable sanitary fixture having at least one floor part, at least one roof part, a plurality of side walls, and a plurality of support posts. The floor part is connected to the roof part and/or at least two side walls to each other via at least one support post. The housing has at least three, preferably at least four, and preferably four support posts of which at least one is hollow, and at least one electrically operated functional device or at least one part of at least one electrically operated functional unit is held in an interior of the support post.
