A portable toilet is a toilet that can move. 

Many of these are chemical toilets. They have a tank to hold waste. They use chemicals to stop bad smells. Some chemicals hide the smell. Other chemicals use biocides. Biocides are things that stop bacteria from growing. This helps keep the air fresh. 
There are other kinds too. Some use a gel to hold liquid in a bag. These are called WAG bags. Other types use a dry way to work. They might use a compost pile to treat waste. Some people use a commode chair. This is a chair with a small pot. It helps people who cannot move well.

Many portable toilets work using chemicals. 

People have used portable toilets for a long time. One early version was the close stool. This was built as a piece of furniture. You can still see these in museums today. For example, a velvet close stool used by William III is at Hampton Court Palace. During World War II, some planes used a type called an Elsan chemical closet. The Bomber Command Museum of Canada says these were not popular with the crews. In the United States, some travelers carried portable toilets in their cars. This happened before the Civil Rights Act of 1964 when public toilets were segregated. 
There are many specific types of these tools. Some are urine-diversion dehydration toilets, or UDDTs. These are often made of plastic or plywood. They are dry toilets that do not use much water. Some people use a collection agency to take the waste away. Others use a compost pile to treat it. 
Portable toilets connect to many parts of our lives. Grand Canyon guides have used ammunition boxes as toilets since 1974. They use these for rafting trips on the Colorado River. This is recorded by the Museum of Northern Arizona in Flagstaff, Arizona. You might also hear old slang terms for them. One old term is a "thunder-box." This was used a lot in British India. Another funny name is "The Johnny on the Spot." This name means the toilet is always there when you need it. 
A portable toilet is any type of restroom that can be moved from place to place. 

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. 
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. 
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. 

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.
