Ever been on the campsite and need to use the bathroom?
Having a toilet in your camper van or RV has always been a source of debate among owners.
But for me, the best toilet has always been the one that's easiest to use, and you don't really notice.
That's why after years of testing different kinds of toilets — whether it's a flush, compost, or cassette toilets — I've decided that that Trelino Evo Series is the best camping toilet.

Evo S Portable Composting Toilet
Compact & Super Light
The Evo S is the smallest toilet in the Evo series. It's ultra-light, compact, and can fit almost anywhere in your van.
Compact, odor-free, eco-friendly. It's perfect.
Specifically, the Trelino Evo S. Here's why:
1) Compact + Portable
The Trelino Evo S doesn't take up much space on the van. It's a small cube. At 33.0x39.0x29.6 cm, I can almost guarantee you have the space for this in your van.
Since it only weighs 8.6 lbs, you can move this thing basically any time, anywhere. It's really the ultimate portable toilet for vanlife.
No headaches trying to find space, or trying to move the Trelino toilet.
The best part is that when I'm on the move, I can store the toilet & nothing moves around when I'm driving. It's unbelievable how compact this thing is, without any sacrifices.
2) Surprisingly Odor-Free & Hygienic
Let's get to the brass tacks here. No one wants their van to smell like an outhouse. Honestly, I can't think of anything worse.
The odor you're expecting comes from mixing liquids and solids (I'll let you figure that one out).
Because the Trelino Composting Toilet Seperates #1 from #2, it becomes extremely easy to avoid that rotten, sewer smell from taking over your van.
You can take it a step further and add litter to the toilet for that little bit of extra safety from odor.
Trelino is releasing their own litter that you can use in your toilet, but any litter will do. If you want to learn what brands they recommend, you can read their blog here.
3) Durable & Thoughtful Construction
This isn't flimsy camping gear. Trelino clearly thought about real-world conditions when designing the Evo S. It's rugged, durable, and built to withstand bumps, knocks, and rugged terrain.
I've taken it on countless trips, and it still feels as solid as day one. It's leak-proof, spill-proof, and built from sturdy materials that can handle repeated use and frequent transport.
Knowing I can rely on this toilet season after season is a big confidence boost when I'm far from home.
4) It Has a Ton of Reviews
It's not just me. People who own the Evo S can't stop talking about how much they love it. From seasoned campers to van-lifers, the reviews consistently highlight its compact size, odor-free experience, and remarkable durability.
I checked dozens of reviews before pulling the trigger, and seeing feedback like "Great product, very sturdy and well made" and "The best camping upgrade I've ever bought" made the decision easy.
The praise is widespread and well-deserved. Once you experience it yourself, you'll understand Trelino has such a high rating on Trustpilot
5) Easy Waste Disposal
One of the main questions everyone has before trying a compost toilet is "Okay... what do I do with the stuff?"
Turns out, Trelino's Evo S makes it way easier than you'd think. Since it seperates #1 from #2, there's only really two things for you to do.
For solids, you just line the container with a compostable bag. Once it's full, tie it up and toss it in the trash or a compost facility — totally hygienic, totally contained.
Liquids can be dumped in any approved site (like RV dump stations or public toilets), and the whole thing rinses clean in minutes.
Let's recap what I love about Trlino:
- Portability The Trelino is so small and light.. you almost won't believe it. It's a truly portable toilet.
- No Scent Because of the separate tanks and compost system, this Trelino leaves no smell.
- Durable While there's no specific lifespan, they're made from high-quality materials and will go the distance.
- Tested & Trusted There's hundreds of happy customers. Take a read through the reviews and see for yourself.
Bottom Line
The Trelino Evo S Portable Composting Toilet is the rare camping gear upgrade that makes your trips genuinely better.
Compact, clean, and completely odor-free. You really have to give it a try and see just how much of a difference it makes.
