Standard units have on-board LPG gas water heating providing copious amounts of hot water for showers and wash hand basins. If internal heating, drying, and lighting is required you need only plug in a small power supply (240v 13amp). Units can also be supplied equipped with toilets and clothes drying compartments in addition to the shower facility.
We also offer shower units with all-electric water heating (instead of LPG). These require a 32amp or 63amp 240v electrical power supply (model dependant) which simply plugs into the trailer; this provides all the hot water, space heating and lighting requirements.
