We have been using this indoor toilet almost daily since the beginning of April 2018 and are very satisfied with it. The system is ingenious and easy to handle. What more could you want! No consumption of water, but free fertilizer, which we, but also our plants in the garden, are happy about. It is a pity that this product did not exist before. We can fully recommend this indoor toilet. Thanks to the developers.

To be honest, I was a little sceptical at first whether it would really work. But what can I say? It’s better than I expected. We immediately bought the model with electric exhaust air and there is absolutely no odour whatsoever. It’s funny that something like this hasn’t been around for a lot longer, because then we wouldn’t have had to buy expensive chemicals for the chemical toilet over the years. By the way, we have disposed of that by now... So thanks again for the great idea!

We bought the composting toilet for our garden at the beginning of spring on the recommendation of a friend, so that we don’t always have to walk so far. Construction as well as the first emptyings were easy. So far we are more than satisfied and our garden is happy with the organic fertilizer.
Kerstin P.
I have owned a composting toilet for about 4 months and I am completely satisfied. I use it as an indoor toilet without exhaust air and it works wonderfully, without unpleasant odours. In the beginning I had some doubts, but these were quickly dispelled. A big praise to the manufacturers, great workmanship and quick feedback in case of questions!

  • How do I use a TROBOLO®?

    Using a TROBOLO® differs little from using a conventional toilet. The sitting position is identical to that of a regular toilet – this applies to both men and women. Thanks to the contact-free separation system the body only touches the toilet seat. Merely urinating while standing should be avoided as the urine cannot be fully separated in this case.

  • Are odours generated during usage?

    Since unpleasant odours only develop when faeces come into contact with urine, the TROBOLO® separation system prevents a mixing of the excretions. Remaining odours and any arising moisture are also absorbed by litter which is not required in a TROBOLO® with an electric exhaust system.

  • How do I empty my TROBOLO®?

    All TROBOLO® models can be conveniently opened from above to remove the two separate containers located inside. After opening the TROBOLO®, the inside containers are sealed tightly with the help of the closures through a simple pressing or screw mechanism, which renders them air- and liquid-tight. The final step is to remove the containers which can then be transported to the emptying location.

  • What is the function of the separation system?

    By separating the excretions, odours are reduced to a minimum and the subsequent disposal of toilet waste is made easier. Unpleasant odours arise only when urine and faeces are combined which is why it is possible to do without toilet chemicals that are harmful to the environment.

Your advantages with TROBOLO®
Odourless separation system
Odourless separation system

Odours are effectively prevented and reduced to a minimum by separating the urine from solid excrements.

Hygienic usage
Hygienic usage

Using a TROBOLO® is just like using a regular toilet. The separation system functions without any contact so that the body only comes into contact with the toilet seat.

No water
No water

By eliminating the need for water flushing, the TROBOLO® system prevents generation of waste water and thus protects the environment.

No chemicals
No chemicals

Due to the TROBOLO® separation system, the use of chemicals is unnecessary. Human excrements do not become hazardous waste, which would require cost-intensive and environmentally harmful disposal.

Easy disposal
Easy disposal

The TROBOLO® separation system enables separate disposal of solid and liquid precipitates. Like used diapers, solid waste can be disposed of together with inlays. The external liquids tank is emptied as waste water.


With great attention to detail, every single TROBOLO® is made by hand, and the different wood grains make it unique.
