Trelino® Evo L • Composting toilet

Haven’t had the pleasure of using the evo L … but there was a light blemish on the side as I removed the packaging, which leads me
onto the choice of plastic used for the outer casing.

It just seems very brittle and easily marked so one drop it will smash to pieces, so durability and it looking nice is at question here.

I am very pleased with my purchase, I haven’t tested it out yet but will be soon.

Lots of use with the EVO. It works great and is sturdy to sit on as a seat or a toilet. But there is no hand holes or handles to pick it up and move it around, You have to push it to move it and the rubber feet are sticky on vinyl floor watch the mess. If you try to lift it the top assembly comes off and its very fiddley to to replace.

I bought this toilet to replace our messy chemical option, hoping for an easier, less unpleasant emptying process, more flexibility on where to dispose of waste (rather than always hunting for an ELSAN point), and a more eco-friendly solution. Technically, it does meet those goals, but unfortunately, the downsides are so glaring that I’m left feeling massively let down—and honestly, ripped off.

First off, the price. At £500, what you’re essentially getting is two small buckets inside a larger one. This is absurd. If you’re considering a composting toilet, I strongly suggest watching a YouTube tutorial and making one yourself. There’s really nothing here that can’t be recreated for a fraction of the price—and with a DIY approach, you might actually build something better.

Next, the capacity. We bought the “large” size for two people living in a van full-time, yet the urine container needs emptying daily to avoid overflowing. The longest we’ve managed is 2.5 days. While daily emptying might sound manageable, the real issue is that you can’t actually see when it’s getting full without taking off the entire lid and seat, which is awkward and cumbersome. And if you do have an accidental overflow, brace yourself. You’ll need to disassemble and clean every individual piece—a far messier job than with a chemical toilet. I’ve never cleaned a toilet so much in my life.

And the design oversight. This feels like it was designed without any thought to real-world use—especially by women. There’s no flush mechanism, which I expected with a composting toilet, but this design flaw becomes a problem during menstruation. The urine-separation hole is tiny (just big enough for a fingertip) and ends up collecting blood that doesn’t drain through. This means you’re left cleaning the hole every single time, poking at it with toilet paper or a finger. For a £500 “mess-free” toilet, this is beyond ridiculous.

Then there are all the small annoyances that feel like they should have been ironed out at this price point. The handle on the urine container gets wet unless you hold it back while emptying. The compost bucket lid won’t click shut when there’s a bag in it. These might be minor, but together they add up—and I expected better from a premium product like this.

Yes, it’s eco-friendlier. Yes, you can empty it in more places. But in every other way, it falls short.

I haven’t been able to make much sense of Trelino’s refund policy, but I assume there’s little hope given it’s been used. Save your money; this is not the easy, clean solution it promises to be.
