Trelino® Evo L • Composting & Camping Toilet

This toilet has transformed our travel in the van. No more chemical smell or looking for a place to dump the cassette. We love the design and functionality. Great product!

I’ve tested a lot of camping toilets over the years, and the Trelino evo L has blown everything else out of the water. Setup was literally “unbox, add coco coir, done.” No pumps, no chemicals, and most importantly no odor. The internal urine diverter keeps liquids out of the solids compartment, so nothing ever turns swampy, even after a full weekend of use. What surprised me most is how home like the seat feels. It’s ergonomically shaped, sturdy, and sits at a comfortable height, no awkward squats in the middle of the night. Emptying is a breeze: the pee bottle twists out with one hand, and the compost bin lifts straight up without drips or mess. Ten minutes and you’re road ready again.
The build quality is legit. At just over 10 lbs, it tucks behind my truck seat without stealing precious cargo space. If you’re chasing off grid freedom but refuse to compromise on comfort or your nose, Trelino is worth every penny. Highly recommended for campers, van lifers, boaters, or anyone who wants an eco friendly, odor free bathroom on the go!

Takes a few times to get the hang of where to sit (either forward or back) but then works great. Still experimenting with what type of media to use for #2. We go through quite a large amount of media in a day for two people in order to control odor. Still notice a bit of funky odor from #2 so we dispose of daily. Overall happy with the Trelino. Customer Service was excellent!

Probably the most amazing thing, NO STINK. If you follow the simple directions combined with good engineering (separate urine from fecal) and it just works. I use in my class B RV and it's SO MUCH better than dealing with the BLACK tank. Horrible, this is fantastic and highly recommend the product.

We are really liking our Trelino. Very simple to clean. Great design. A nice upgrade from the nasty carry on suitcase of poop that was the cassette toilet in our last camper.

First toliet arrived broken in a few spots. Customer service was quick to get a new one shipped out once I sent the broken one back. My main complaint is the high cost for such thin material. Removing the top, or opening the lid is a bit of a challenge due to the tiny little lip they give you. The separation portion works great. I just think for what it is, it could be priced better. I'd say it's a 3 star item with 5 star customer service.

This toilet was a life saver for me on a camping trip, it was excellent!

I LOVE the Evo L. It's the perfect size for our Sprinter Conversion and it sits out in the open without telling the world what it is. It has multiple uses - extra seating, ottoman, table, etc. I was torn between the Origin and the Evo but glad I chose the Evo L because it's the perfect height.

It's very sturdy plastic and disposal of both the solid and liquid containers are easy and non-smelly. I'm glad I chose the Trelino.

After much research, I chose the Trelino Evo L for my new travel trailer. I do NOT want to deal with black water. About two weeks after the Trelino was delivered to my home, my area experienced a historic flood which swept away the pumphouse of our well. A week later, another worse and catastrophic flood hit our area. I have been without water in my house for over two weeks, which means the toilets cannot be used. I am SO happy and grateful that I already had the composting toilet! It has made continuing to live in my house during this difficult time possible.

I love the height of the EVO L and with the Trelino® Vela • Privacy Flap for Composting Toilet Evo, it becomes the perfect urine only toilet for guests. I absolutely love the EVO L with the privacy flap. Thank you for listening to us and coming up with the privacy flap; urine only toilet. It is just the best!!!

This is my second trelino toilet. My first one was, the medium sized one. I up sized to the large one, being I live full time in my bus, the extra capacity is a win. Highly recommend, it looks great, blends in and doesn't SCREAM toilet😁

I highly recommend this composting toilet. I've had no problem with odors. I use saw dust and peat moss to cover the feces and it is virtually odor free. Like others I do wish they had an indicator to alert one that it's time to empty the urine, but it's simple enough just to check it from time to time. It's a sturdy, well built toilet and anyone who lives off grid or does a lot of camping will do well with this device.

We liked how our Trelino toilet made it easy to convert from a smelly cassette toilet on our camper van. The toilet is compact and sleek looking, it’s easy to use and to empty. In fact, we liked it so much we bought a second Trelino for our sailboat.

It does the job !

I haven't put it together yet! I'll let you know how it goes.

With two potty training toddlers having to stop at grungy truck stops and other shady places was killing our road trips. The trelino has saved the summer by making it easy to take with us on all of our trips. It fits perfectly into our truck camper setup too!

We have used Trelino in three of our camper van builds and recommend them to all who tour our vans at van shows and gatherings. We love them and will always use Trelino for our tiny bathroom needs.Thanks Trelino!

For our simple cargo van camper build, we bought a Trelino composting toilet which has worked out very nicely.

I enjoy my new L serious. They come in very handy when you have a problem with your plumbing. I have 1 at home and 2 at my camp. Enjoy them very much. Thank You.

The Trelino compost toilet is exceptionally well designed and incredibly easy to use. From setup to daily operation, everything feels intuitive, thoughtful, and user-friendly. The design is sleek and compact, making it a great fit for small spaces, and the overall functionality works exactly as intended. Emptying, cleaning, and maintenance are all straightforward, which is a huge plus for anyone new to composting toilets or looking for a low-hassle solution.

That said, the only reason I am giving this product four stars instead of five is the price. While the design and ease of use are excellent, I do feel the cost is quite high for the materials it is composed of. The product performs very well, but the pricing may be difficult to justify for some buyers when considering the material construction alone.

Overall, this is a high-quality, well-engineered compost toilet that delivers on usability and design. If price is less of a concern, it’s a solid and reliable option that I would confidently recommend.

We are absolutely loving our new large EVO! It’s a great height, we thought it might be too short when looking at the measurements but it is actually a very comfortable height, I’m 5’6” and my husband is 5’10”.

What we love the most though is the extra volume in the urine tank, I think it’s 2X the volume of the Medium EVO and much larger than any other separating toilet on the market. Not having to empty the urine tank as often or worry about overfilling is a huge deal for us.

Great product!!!

This is our third Trelino toilet. We put this Evo-L in our Sprinter van, adding to our travel trailer’s Evo-L and our truck camper’s Evo-M. Easy to use and clean. Solid construction and excellent design. Been using for more than 4 years. Extends boondocking by saving water. Forget your RV’s black tank. Highly recommend for all car, truck, van, and RV campers.

Saves water, money, time and trips to black tank dump. Only problem, it didn't come with a urinal plug for inside toilet. When your driving it can splash out of canister back up in into toilet. Plug should come with toilet in case you can't empty canister.

I notified team trelino about not receiving the plug with the toilet which was ordered at the same time as the toilet. Toilet arrived but no plug, waited in case it was sent separately. After a couple of weeks on November 13, I texted team trelino and got a reply from customer services that she would notify the warehouse to send it but as to now 2 weeks later nothing has arrived. Once I receive the plug and I’m able to use the evo large toilet I can give report on how well it works. I would appreciate if you would send the plug soon . Thank you

Price was a little high. There was a couple others that might’ve been comparable but with all the reviews I read it supposedly is going to be the best have not used it yet, but it looks well made and I like the way it looks.
