A portable toilet is any type of restroom that can be moved from place to place.

Some units are small enough for one person to carry. Larger models may require mechanical equipment, such as a truck and a crane, to move them. These devices are useful because they are self-contained. This means they do not require any pre-existing infrastructure. They do not need a connection to a sewage system or a septic tank.

Because of this independence, they are used in many different settings. You might find them at music festivals, construction sites, or film locations. They are also essential for camping, boating, and use in urban slums in developing countries.

Most portable toilets function as chemical toilets. This is the most well-known type of mobile restroom. These units collect human waste in a holding tank. To manage the environment inside the tank, they use specific chemicals. Some chemicals work by masking the odor of the waste. Other chemicals contain biocides, which are substances that stop odor-causing bacteria from multiplying. By hindering these bacteria, the chemicals keep smells to a minimum.

This method is common in enclosed plastic or fiberglass rooms used at large outdoor gatherings.

There are many specialized versions of portable toilets designed for specific needs. One type is the urine-diversion dehydration toilet, or UDDT. These are self-contained dry toilets often made of molded plastic or plywood. They separate urine from solid waste. Users often rely on a collection agency or a post-treatment process to reduce pathogens. This treatment might involve long-term storage or adding waste to a compost pile.

Another type is the WAG bag, which stands for Waste Aggregation and Gelling. These bags use a gel to immobilize liquid waste and surround solid waste in a plastic bag. They are used by the US Army and in wilderness areas.

Other designs serve very specific environments or people. On planes and trains, you might find either chemical toilets or vacuum toilets. For travelers in camper vans or caravans, portable camping toilets are common. These have a seat and a small waste tank. Small boats that lack built-in marine toilets can also use them. For people with limited mobility, a commode chair is a helpful tool. This is a chair that encloses a chamber pot. It is often placed next to a bed to help someone move around more easily.

Portable toilets have a long and varied history. One of the earliest forms was the close stool. These were built as pieces of furniture. You can still see them in museums, such as the velvet upholstered stool used by William III at Hampton Court Palace.

During World War II, bomber aircraft used a type called the Elsan chemical closet. However, the Bomber Command Museum of Canada notes that these were not popular with the flying or ground crews.

In the United States, some travelers carried portable toilets in their cars during the era of Jim Crow laws. This was because many public facilities were segregated by race before the Civil Rights Act of 1964.

Different cultures and groups have even created their own unique ways to use these tools. Since 1974, guides rafting on the Colorado River in the Grand Canyon have used ammunition boxes as portable toilets. These boxes typically feature a removable toilet seat. This practice is documented by the Museum of Northern Arizona. People have also used many slang terms for these devices. In the past, a "thunder-box" was a common term, especially in British India. Another phrase is "The Johnny on the Spot," which describes a toilet that is always conveniently available.

Today, portable sanitation is a broad field that connects to many different systems. Container-based sanitation is a system where full containers are regularly replaced with empty ones. This ensures that waste is collected and disposed of properly. From large-scale festival setups to small camping gear, these tools solve the problem of hygiene when permanent plumbing is unavailable. They allow humans to live, travel, and work in many different environments across the globe.
