There are various reasons for buying or building a composting toilet yourself. In most cases, the space inside the vehicle plays a decisive role.

What is the argument for buying a ready-made composting toilet? 

  1. The place where your composting toilet will be located has enough space. This is the perfect starting point for you to start looking for a model that best suits your needs and requirements. In this case, you are spoiled for choice.

  2. You have neither the time nor the inclination to build a composting toilet yourself. Maybe you don't like manual work at all. In this case, buying a composting toilet is clearly the right decision.

  3. You find it difficult to plan a craft project from scratch. Before you can build a composting toilet, you must first consider and take into account many points. These range from size and volume planning to choose the right material and potential venting. If this is a horror to you, we recommend buying a ready-made composting toilet.

What is the argument for building a composting toilet?

  1. The spatial conditions at the installation site of your composting toilet are too small or too special for common models from the trade. This may be the case in small vehicles or in the case of special factory features, such as a built-in bench toilet, into whose conversion the new toilet is to be perfectly integrated.

  2. You love to take things into your own hands. As a passionate craftswoman or tinkerer, the construction of a composting toilet is an exciting project for you.

  3. You love and live individuality. An "off-the-peg" toilet is out of the question for you. Then a self-built unique piece is just right for you.
