The TROBOLO KitaBœm is made of FSC®-certified 23 mm thick solid pinewood, in consideration of constructive wood protection which serves to prevent waterlogging and is therefore very robust and durable. The surfaces have been pre-treated to such an extent that they can be directly coated. The interior construction is made of FSC®-certified 18 mm thick alder plywood. The separation system is made of durable plastic and its surface has been sealed.

This is how our customers rate us at Trusted Shops

The Trobolo stands in our nursery school in the outdoor area for the kids. We bought some extra children’s seats, too. Has been in use for several months now and works brilliantly, everything ends up where it should. We do have to sort out the emptying ourselves, but thankfully it’s quite quick to do so and ultimately, it’s a lot faster than constantly having to run inside to do your business.
We decided to go for the Kersaboem due to financial reasons. Because the ongoing costs for a portaloo are mental in the long run!!! The set-up was as described: easy, but it did take me more than 20 minutes, but then again, I did do it by myself. We’ve been using it daily for a week now. Absolutely amazing! No more of this portaloo stink and all that plastic. I’ve also emptied it once already, it wasn’t necessary yet, but I still wanted to try it out. I was expecting worse and even my daughter didn’t run away. Didn’t think that this little odour would develop, simply by separating the urine. The emptying didn’t take longer than 2 min.
Renate W.
We got the composting toilet for our garden at the beginning of spring following the recommendation of a friend so that we don’t always have to walk as far. The set-up as well as the first few times emptying it were easy. So far, we’re more than satisfied and our garden is happy about the organic fertiliser.

  • 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.
