Common materials for composting toilets

Composting toilet materials


Most composting toilets are made of plastic. Due to its versatility, the material offers many advantages and is therefore very popular.

Plastic toilets are very easy and effective to clean. Due to their water resistance, you can even rinse them out with a garden hose if you are in doubt about heavy soiling.

One disadvantage of plastic is that the material can become brittle or discolored in the long term due to exposure to sunlight. In addition, plastic is also less robust than wood, for example, depending on the type of production.

Possible uses: Ideal for use in vans, RVs and smaller living spaces where weight and space are limited. Also, great if you want to move the composting toilet, such as when used in a tent.


Separating toilets made of wood give their place of use a wonderfully natural charm. They are environmentally friendly and fit well into natural environments. Due to their weight, separating toilets made of wood have a special stability.
