At 10.8 lb the Trelino® Evo L is easy to transport.

Area of application
With a comfortable seat height and large volume bins, the Trelino® Evo L is suitable for installation in RVs, Skoolies, large vans, off-grid cabins or tiny houses.

Odor neutrality
The separation and drying function of the toilet prevents unpleasant smells.

By dispensing with chemicals and water, the Trelino® Evo L is environmentally friendly and preserves natural resources.

Without water and chemicals, the Trelino® Evo L offers the freedom to travel independently of disposal stations.

Hygiene and cleanliness
Individually removable containers allow separate emptying and easy cleaning.

Leakage safety
Due to the solid workmanship, the exterior is leak-proof and protects against unpleasant mishaps on the road.

Water resistance
The exterior made of polyethylene is water resistant and therefore can also be used in the shower.

The Trelino® Evo L is a stable, robust and insensitive and dry separation toilet that accompanies you everywhere.

A fan can be installed for even faster drying of the solids. The hole in the separation toilet for the fan must be drilled yourself. We recommend a step drill 1.53 inches.

The body (made of acrylonitrile butadiene styrene, ABS) and container (made of polypropylene) are made of recyclable plastic and are resistant to aqueous chemicals.

Lid attachment
The lid, which is attached to the toilet seat, has an automatic soft close feature.

Clean design with a difference!
With the Trelino® Evo L, you can choose between two colors (white & dark grey).

Regional production
Production is carried out exclusively in Germany, taking into account high social standards.

How does a composting toilet work?

The inner workings of a composting toilet essentially consist of three parts: separator, urine canister and solids container. The separator leads the urine into the canister, while the solids end up in a bucket with a compost bag. You can also read a more detailed version in our blog post here.

What should I pay attention to when using it?

The correct sitting position is crucial for the best possible function of a composting toilet. For anatomical reasons, this differs for women and men. 

Why does a composting toilet not smell?

Odors are caused by the mixing of solids and liquids. Separating the excreta and then drying the solids prevents undesirable aromas. 

Do I have to change/empty the plastic bag after each use?

No! The whole point of using litter as a cover material to dry out the poo is that you can use the bag for several days and only empty it once full enough. Depending on the size, the bags hold between 3 and 12 number 2s.

Where can I get the litter / cover material to dry the solids?

You will be able to buy litter from us some time early next year. Until then or otherwise you can also buy good litter material from any garden or home improvement store. Find more info on our blog post about litter here.

Do I need a fan?

For other types of toilets, you might think about using a fan to counteract condensation, which accelerates the drying process of the solids and ensures that fragrances quickly dissolve into thin air. This is not necessary for your Trelino® because you would use a litter material after each use which dries out the solids and removes the smell. On top of that, the emptying cycles are quite frequent so you can very quickly dispose of your bag.

What happens when I have diarrhea?

Diarrhea is not a problem when using a composting toilet. Just use more litter to compensate for the liquid.

Where do I dispose of the contents?

Urine can easily be disposed of in a toilet connected to the sewer system. Diluted, it is also suitable as fertilizer for the home garden or the raised bed on the balcony. The bag with the solids is a case for the residual waste garbage can. Conditionally, composting is also possible. The urine canister and solids container can be emptied independently of each other.

Plastic bags and composting - how do they fit together?

For us, sustainability and environmental awareness do not end with disposal - we think beyond the garbage can. That's why we use renewable, organic materials for our solid bags that can be easily composted.

How do I clean a composting toilet?

Cleaning a composting toilet is as simple as its use. The household remedy diluted vinegar concentrate has proven its worth for most of the cleaning. Read more about it in our blog post here.

    So glad we were finally able to buy one!

    We saw the Trelino Evo L on the @DownToMob YouTube channel. I immediately wanted one! We typically camp in state campgrounds which have public bathrooms. I prefer to use my own in my camper. But every year we go to Colorado to elk hunt and are in the mountains for two weeks boondocking. We’ve always had the usual 2 pc camping toilet. Thankful to not have to use a log, but it was always a smelly hassle to deal with and very hard to handle to empty. As soon as I saw the Trelino on Phil’s channel I knew it was the answer I had been looking for!! We’ve used it on 2 campouts so far and I’m happy to say my hopes have been met! It is soooo easy to empty and clean, I’m loving it. I’m still learning what is the correct amount/type of medium to use, so far I’ve used the coco coir and been mostly happy with it. I’ve told everyone who camps with us about my new toilet, lol. Not the usual table talk, but they have been intrigued! Fantastic design, wonderful ease of use, couldn’t be happier!

    Birgit (United States)

    The best decision I made! Comfortable, easy to clean, enhances vanlife and camping! Now, I am even more relaxed!
    One wish, please add handles , would make it so much easier, to pull/ slide it out. Thx!

    The Best

    I had a composting toilet before, but it was very difficult to clean. Trelino has made it so easy to clean and it looks great.
