portable toilet or mobile toilet is a toilet that may easily be moved around. They may be toilets that can be brought on site, such as a festival, concert or building site, to quickly provide sanitation services. Others may be toilets within mobile vehicles, such as boats or caravans. Some are re-usable and may be moved on to further sites, others are easily installed but become permanent once in place. A major characteristic is that most types do not require any pre-existing services to be provided on-site, such as sewerage disposal, but are completely self-contained.A bathroom is a room in the home or hotel for personal hygiene activities, generally containing a toilet, a sink (basin) and either a bathtub, a shower, or both. In some countries, the toilet is usually included in the bathroom, whereas other cultures consider this insanitary or impractical, and give that fixture a room of its own. The toilet may even be outside of the home in the case of pit latrines. It may also be a question of available space in the house whether the toilet is included in the bathroom or not
