Caravan toilet in comparison

Caravan Toilet

Caravan toilet – comparison –  that´s what this article is about. We will differentiate between the standard chemical toilets and  more and more frequently used composting toilets. Both have a similarly long history.

In particular, we will present the advantages and disadvantages of individual toilets. 

There are the following types of caravan toilets: chemical toilets and sustainable mobile home toilets. The chemistry toilets are still very common. However, these are no longer up-to-date for they use chemical additives, which pollute the treatment plant. In contrast to this, lasting camping toilets have become ever more popular. They work without chemicals and without water. If you are looking for detailed information about how a composting toilet works, then have a look here: How a composting toilet works.

mobile home toilets

In our shop, you will find many more suitable composting toilets for the motor home. Feel free to take a lot at it!

The caravan toilet is usually permanently installed. It should be ready for use at any time and offer a similar comfort to the toilet at home. This includes simple handling and maintenance of the toilet. 

1. History of the caravan toilet 

If one thinks of a caravan toilet, most think of the classical cassette toilet, which is a common standard in almost all caravans. The toilets from Thetford, Dometic, or Enders are probably the most common among chemical toilets.

In 1960 the American Frank Sargent invented the camping toilet. It was similar to the Porta Potti. In 1963 Sargent founded the Thetford company, which spread worldwide. In 1988, the classic cassette toilets came onto the market and moved into all motor homes.¹

At this point, we would like to express our gratitude to the Thetford company for equipping the motorhomes with toilets and thus making motorhome travel more independent and free.

Cassette toilets became generally accepted as mobile toilets.

The permanently installed cassette toilets are gaining ground compared to mobile chemical toilets because they are easier to handle. Only the cassette must be changed by an outside compartment in the mobile home. The rest of the toilet remains firmly installed in the motor home.

Composting toilet – alternative living mobile toilet

The composting toilet also has a long history. The development of the dry toilet began in Sweden at the end of 1930. In 1970 the dry toilet was also used in the USA, in national parks. Nevertheless, water toilets have gained acceptance. The composting toilet is hygienic, odorless, waterless, and environmentally friendly.

A simple dry toilet does not necessarily separate the solid and liquid components. A composting toilet separates the residues from each other so that the rotting processes do not take place at all. The urine can be used diluted in the garden as fertilizer. Of course, it can also be disposed in drains.

In the composting toilet, the solids are covered with spreading material, such as sawdust or bark mulch, which aerates and dries them out. This way, they can be collected for a longer period of time and are finally either put into the garbage can or onto the compost. Some also bury the solids when no other option is available. In this way, no animals can get at it and nature transforms the organic mass into the soil. The solids have a peaty structure, so it is not unpleasant to dispose of them. Because the excrement dries out, odors do not have a chance in the separating toilet.

Gradually, the demand for alternative toilet concepts for mobile use, such as for motor homes, boats, or camping, is increasing. The decisive difference is the created independence from supply and disposal stations. Separate toilets offer the possibility to stand freely for longer periods.

2. Advantages and disadvantages of the individual caravan toilet

1. Classic Cassette Toilet

A caravan toilet must be practical and therefore the cassette toilets developed in the ’80s became generally accepted. Instead of going into the sewerage system, everything is put into the cassette and collected there. The store is flushed down with water. The handling is similar to the toilet at home. Sit on it, flush – finished (for now). The big difference lies in the regular disposal of the collected feces in the cassette.


  • Cassette toilets are usually already built into the motor home. Thus also all connections are already present.
  • Nothing else has to be done during the toilet visits, except flushing.
  • Usual toilet use with flushing
  • Lower purchase price ~ 600,- €


  • The cassettes have a filling capacity between 17 l and 20 l. With 2 persons one cassette is full after about 2-3 days and must be emptied.
  • Due to the mixing of the excrements, odors are created which are covered with chemical additives.
  • Disposal and cleaning need to be carried out at special supply and disposal stations.
  • More harmful to the environment, since chemicals are used
  • Full – weight = over 20 kg
  • Water consumption
  • Follow-up costs for chemical additives and disposal

2. Bio Toi Caravan toilet

The Bio Toi has only been on the market since winter 2020. It combines the advantages of compost toilets, such as agitator and water resistance. It also offers other advantages. The solid material container is simply lifted out from above. The usual composting toilets have to be dismantled to remove the solids container. Furthermore, the Bio Toi is particularly compact, so that it fits into even the tightest installation situations. All materials are of high quality and durable. The opening to the solids container is larger than the two competitors, the AirHead and NaturesHead. This makes it easier to hit the solids container. The stainless steel look is of course a matter of taste. Despite the compact dimensions, the containers have a sufficient size. The urine canister is 10 l larger than the competition. The solid matter container with 15 l is a little smaller. Nevertheless, the 15 l volume is sufficient for about 30-40 sessions. The standard version has not only a crank but also a fan.

The toilet is built very narrowly and is suitable optimally for campers, boats, and caravans. It weighs 14.5 kg. The NaturesHead is suitable for fixed installations and wet rooms. An 8.3 l urine tank is built-in and the solids container is sufficient for about 60-80 sessions. The NaturesHead also has a crank and a fan.

5. Trelino L

The new Trelino L is a very compact waterless toilet, which fits even in cramped installation situations. This caravan toilet has also only been available since the winter of 2020, and its dimensions mean that it does not require more space than many narrow cassette toilets. An advantage is a lid that can be opened upwards, as this means that no additional space is required at the back.
