Abstract

The present invention extends to wagons with a bathroom module and standalone bathroom modules. A bathroom module includes a water heater connected to a sink, a shower, and a toilet. The bathroom module further includes a protective layer on the exterior and an exhaust fan to facilitate the management of moisture that may build up within the bathroom module. The bathroom module can be connected to various systems provided by a wagon, such as water, gas, electrical, A/C, heat, and sewer systems connected to external sources. Alternatively, the bathroom module can standalone and include its own water, gas, electrical, A/C, heat, and sewer systems connected to external sources. Thus, when paired with a companion wagon, the bathroom module may be installed or removed as desired.
