The actual container is more commonly referred to as a "portable toilet" or "restroom trailer" rather than a "container of toilet." These are complete units that frequently have a toilet, sink, and occasionally a shower. They are frequently utilized in outdoor events, building sites, and other locations with restricted access to conventional plumbing. While some portable restrooms are standalone units that can be delivered and set up on location, others are standalone units that are designed to be transported on trailers.
