How does a composting toilet work?

A separating compost toilet has three main pieces: separating insert, urine canister, and a solids container. All of these work together to make sure your camping toilet is dry and smell free! The separating insert funnels the urine into the canister, while the solids are kept separate in their own container lined with a bag and a drying litter material. To learn more, you can check out our page:  "How Does a Composting Toilet Work?". 

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. Women may need to sit up straighter or closer to the front. For more tips on this, you can read our article here. 

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?

Nope! Trelinos are urine diverting toilets which keep everything as dry and smell free as possible. As long as you are using a good litter material to cover your solids, they should be dried out and have no smell which means you don’t have to empty the bags after each go! Depending on the size of your Trelino®, the bags hold between 3 and 12 number 2’s.

 

Which litter / cover material should I use to dry the solids?

There are a variety of different sprinkles you can use in your solids container.
We recommend small animal litter or coconut coir. While these are our top suggestions, there are still numerous alternatives that our customers use. For more detail on these options, you can read our page "Consider Your Litter".

Do I need a fan?

A fan counteracts condensation, accelerates the drying process of the solids and ensures that fragrances quickly dissolve into thin air. This makes it particularly suitable for long emptying cycles or if your Trelino® is used by several people. Due to its compact dimensions and short emptying cycles, the small Trelino® options do not need a fan.

What happens when I have diarrhea?

Diarrhea is not a problem when using a composting toilet. Actually, having one so close should help you in those emergencies. You only need to sprinkle on more litter after the fact to help absorb any extra liquid.

Where do I dispose of the contents?

The urine canister and solids container can be emptied independently of each other. The urine can easily be disposed of in a toilet connected to the sewer system. Just pour and flush.  Diluted, it is also suitable as fertilizer for your home garden. The bag with the solids can be disposed of similarly to a diaper or dog poo bag. We recommend checking local regulations for disposal guidelines. Conditionally, composting is also possible. 

Which bags should I use to line the solids container?

You can start by using the 10 bags that we include in your Trelino® order. These are thicker bags made from recycled materials that will make sure your waste stays in the bag and doesn’t leak through. You can also use bags made from compostable material if you are looking to compost your waste. 

How do I clean a composting toilet?

Cleaning a composting toilet is as simple as its use. You can use diluted vinegar, citric acid, or even microorganisms to clean your Trelino®. There are just 3 easy cleans that your toilet would need. 1) Spray and wipe down the toilet “bowl” and seat as needed 2) Every 2-3 days empty then rinse out the urine canister with your cleaning solution. 3) When full, just lift up the bag in the solids container. 

What makes Trelino® so special?

The value in our product comes from our high standards of production and a conscience towards our partners, suppliers and employees.We want to do justice to everyone in our supply chain and our company by producing the toilets in Germany, under fair conditions. 

We also have committed to high standards of production. To take a stand against disposable culture, we have designed and built our toilets for longevity. Made from high-quality plastic, each Trelino® is meant to far outlast lesser made products.

Completely satisfied!

After long deliberations, many videos and lots of forum reports, the decision was made. A composting toilet is needed, namely a Trelino L for our Adria Compact Supreme DL. Ordered and turbo delivered. Everything 1A, both the information on our questions and the delivery. Old toilet out, new one in, everything adjusted with turntable and everything can be completely dismantled again. Then another longer test in our house and '.. we are super satisfied. It is actually as described in the many videos. Little effort, no smell. It takes two or three days to find out how to sit, how to care for and how to add the bedding, but it really isn't rocket science. And the service was just great. After our test, my friend immediately ordered one. This is also installed and our friends are very satisfied. So thumbs up from us👍👍 and thanks for the support and the good product👍 Peter (translated to English)

Perfect for us

Purchased this to take the edge off camping. Meets our sense of aesthetics, multiple uses for it besides the obvious. Easy to clean. Could only be better if there were some handles to make moving it around easier. Well done.

Great addition to my rig!

I went from collapsible toilet to a 5-gallon bucket in my campervan. Once I started traveling for 3-4 weeks at a time, sometimes at Hipcamps and Harvest Hosts, I knew I needed to think about a longer term solution that kept the smells at bay. This Trelino toilet is amazing! I can go a few days before emptying and there are NO smells. I'm so happy I was able to upgrade!

Appreciated the customer service!

We started out with the Medium, and found that it didn't hold as many number twos as we expected, which was disappointing since we LOVED everything else about the system. Customer service worked with us to make upgrading to the Large an affordable option (they understandably don't accept returns on used toilets). We're super grateful for their responsiveness and find the L to be a perfect toilet solution for our small truck bed camper. Aesthetically pleasing and functional. Can't ask for more!

Well-made, but there is much room for improvements.

The Trelino Original is possibly the best-made toilet in its class. It is well designed, sturdy and looks very nice. I found disappointing in several areas, especially in light of its high cost. First, the wooden lid is much too light, somewhat flimsy and has no finish. Second, it needs to be hinged so it can be raised and not removed. Finally, as it stands, it is difficult to move. A pair of recessed handles on the sides would address this. Would I recommend it to others? Probably, but not before the changes I listed are made.

Hello,
Thank you for taking the time to leave your feedback, we are always happy to receive constructive criticism.
As far as the cost, all our Trelino products are designed and manufactured in Germany, ensuring high standards in craftsmanship and sustainability. For example, the wooden lids themselves are handmade in a local workshop. This production does lead to higher costs. We don’t put a finish on the lids so that they can be stained to match interiors. Once a finish is applied, then the color cannot be changed.
Thank you for your feedback on the handles. This is a feature that we have been considering, so we are happy that we have been able to get more feedback on this so that we can keep improving.
-Your Trelino Team

Great Product

I recently bought the wooden-seated RV version of the Trelino toilet. I put it into my trailer located in Oregon mountains near Idaho border. At $750 it was not cheap. But it is a solid product and works well. So much easier than the cheaper Walmart products which have much less thought built into them. It is worth the money.

Very well made and excellent design. I have a cassette camping toilet. The Trelino is so much easier to use and much easier to dispose of the waste.

Unexpected tryout

While we have not yet had a chance to tryout our Origin L on the road we have had a chance to use it.
A week before Christmas we had a sewer line break in our home (not actually inside but outside...Thank God!!). 3 weeks and $5600.00 later we have working plumbing again. Our Trelino was put to the test and performed admirably. Went to the pet store and got some Aspen shavings and coconut coir. As long as the toilet was closed it was odorless but take off the top, and while not overpowering, one couldn't help but know what it was full of. Just a matter of adjusting amounts of litter and I'm sure we can do better.
All in all I think we have a winner and can't wait to "take it on the road".

no stress

love this toilet, best investment for my van travels. no stress about toilet things anymore. super straightforward design & easy to use. i got the largest toilet, it would be nice for the outside to have handles on either side for easier handling, the entire toilet is hard to carry if i need to remove it from inside the van.

Love it!

Perfect fit for our life

We just received our Trelino Origin L composting toilet and have placed it in our RV. This allows us to conquer two things: 1) we can go off-grid for longer time periods and 2) we're using a LOT less water with the composting toilet. So far, it is easy to use, easy to set up, and has not had odour. We think we're going to like this change!

Trevino origin L toilet

Love the size. Well made. Fits perfectly in our van wet bath. Only con is urine container and blue bladder under cover seems to hold or absorb urine smell even with cleaning with vinegar/ water solution.

Thank you for your review! To help with the smell on the urine container, I would recommend a few tricks to try out. You can try switching to a citric acid/water solution. Then if there is lime build up which could be causing the smell, you can use the same solution but a little more concentrated in order to tackle that build up. And finally, if you do have the time, once you are done cleaning you can give your container some time to air dry before putting it back into the body of the toilet.

Fantastic toilet - Works just it says it does

We had a Natures Head and were constantly fighting with the dump of the number 2 as had to lift the whole bottom of toilet, after removing the lid. Living on a sailboat space is limited and this was a chore. With the Trelino and the use of a bag it has changed our lives. No more dreading the number 2 change. LOVE OURS.
