Pretty expensive for a low tech toilet

A couple things about the toilet, I like, and a few things really make me wish I could return it. I got the large one, thinking it would have some pretty decent capacity. It really has a small capacity, and may be good in a pinch, but for full time use, it’s too small. The pee jug fills up really fast, and there is no way to tell how full it is. You would think a peep hole, and a clear bottle would be good so you can actually see how full it is.

The pee bottle is also hard to dump, and the handle always falls down, inevitably covering the handle with pee. Not ideal.

I like the soft close lid, but everything else I was kinda disappointed about for a $700+ toilet.

Hello Zeb,

Thank you for sharing your detailed and honest feedback. I’m sorry to hear about the issues you've encountered with the toilet, particularly regarding the capacity and handle.

We are happy to try to address your points in more detail and improve your experience.

We are currently developing a level indicator that will be available in the shop in the first half of 2025. We understand that the lack of a fill level indicator makes it somewhat difficult to use and therefore recommend defining a fixed time to check (ex. daily in the morning). Another indication of the fill level is the changing sound when urinating.

A person can approx. .5-.75 gallons of urine every day. Everyone is of course different in this regard and for 2 or more users, there is even more of a varible. For cleaning purposes, we do usually recommend emptying the canister every other day, regardless of fill level.

Thank you for your feedback regarding your issues with the handle while emptying. Getting this type of user info helps us to improve our designs or create solutions.

If you have any further questions, please do not hesitate to contact us.

Membrane lifespan

We love our Trelino, however the membrane closure on the urine container doesn’t stay closed for more than a couple of weeks. We’re on our second one.

AMAZING!!

This toilet is everything we wanted and more! It has a sleek design and is simple, yet high end feeling.

Trelino large toilet

Seems like a good quality toilet, well built. However, I had it shipped to my mom's house and my younger siblings and mom were not happy with the expletive words on the packaging. I get that its meant to be funny, but for a professional company it dampened the excitement for this thing. Especially with my younger siblings seeing that. I can't imagine a professional company like chicago faucet or Delta doing the same... it seems like I got a meme toilet or a trendy one rather than a well built one.

Trelino Evo L

Absolutely love it. It is exactly what I wanted for my off grid living. Thanks.

The rubber pee valves are not like the original at the end they have a gap

Please advise if I've received 2 defective valves.

Hello Nancy,Thank you for your feedback and for bringing this to our attention. We’re sorry to hear about your experience. Could you please contact our customer service team at hello@mytrelino.com? To assist you as quickly as possible, we kindly ask that you include photos of the defective membranes in your email. If the item is indeed damaged, we will of course send you a replacement right away.
Please note that the membranes are always slightly open by design to prevent the membrane lips from sticking together. Additionally, this slight opening allows air to escape from the canister, preventing internal blockage when liquid passes through. Without this feature, there would be a risk of overflow. We hope this explanation helps clarify their functionality, and we look forward to resolving this matter for you promptly. Best regards, your Trelino Team.

Wished I Bought Trelino First

The Trelino Evo M is my third portable toilet for my camper van, and it’s by far the BEST! Its design is simple yet incredibly effective, making it a game-changer. No more lugging around a heavy, water-filled toilet or dealing with the unpleasant task of emptying and cleaning it. Trelino toilets are the ultimate solution for hassle-free camping convenience!

Trelino® Origin L • Composting Toilet for RVs

Simply the best

This toilet not only is the best but it looks the best. That’s all, there is no other competition even. 5 stars

Nice crapper!

I haven't used it yet but it looks really nice, fits like my porcelain throne at home.

Never Received Toilet

Never received toilet. Notified Trelino, they called once, I told them I never received toilet and never heard back. I'lll be disputing charge.

Game changer

I was camping, now I’m glamping. Love it!

Eco S

This has made trailer camper much easier. It also opened space in my 16’ Scamp where every inch counts. When it’s not being used, I store it under the bed to free up floor space. Never any oders.

Best pooper around!

My Ford Transit is my everyday vehicle. I travel with easy thoughts knowing I always have a place to GO.
This toilet separates the the pee from the poo. It keeps any odor in check. It is easy to empty and keep clean. Highly recommend.

I wish I could like this product

It’s honestly just really disappointing. It was so expensive and just not very good. The shape of the pee container makes it really awkward to empty, and the lidless poo container smells every time I open up the top lid. The membranes get pushed out of place sometimes when I put the lid back on, and sometimes they fall all the way in. It’s not because the membranes are bad, the whole thing is just not a good design. I’m afraid I’ve wasted my limited funds on this product.

Works Awesomely!!!

On the plus side, Trelino's design is lovely and discrete, compact and comfortable to use. It is the best solution I've found (and truly there aren't that many solutions). The poop basket with litter or wood chips works wonderfully well but the urine chamber retains odours even with daily disposal and with the recommended vinegar/water treatment (I keep experimenting on ratios). Also, for the very expensive bit of kit that it is, the thin underside surrounds of the top piece which one must handle when removing the top could be a bit thicker and more rounded for comfort and safety.

Nice travel toilet

This toilet is a great option for composting being able to throw away number two out daily is convenient. Having a fan option to control odors would be great addition. Another great thing to add to this would be a platform to rise it up a little and also be used for storage like a competitor toilet. Aesthetic of this toilet is much nicer

Not sure

Will be using next month. Will test it then

Great Simple Toilet

I think this will be May favorite camping toilet. I own two other camping toilets, the Clean Waste Go Anywhere and a Wrapping Green (now called the Trekker). The CleanWaste toilet I only take a long on long day trip in case needed or a quick & minimalistic overnighter. The Wrapping has been my go to toilet for years and has served me very well. The cons of both systems is the cost of bags. The Wrapping, while it has been awesome, has the added complexity of needing power & setup. I made my small battery pack but when the vehicle is packed, you can't just pull it out quickly for a rest stop.
I ordered the Trelino Evo L to have a lighter weight & simple setup. I got the L simply due to the more comfortable height after all no one gets younger. I made a Trelino accessory kit box using an Outdoorcrates OC7 gray box. My kit contains: 4 rolls of TP, 2 butt wipe packages removed from their container g in a small outdoor products mini dry box, 1qt nalgene of white vinegar, 1qt nalgene of urine neutralizer odor eliminator, 1 spray bottle of the urine neutralizer, & a 5L sea to summit bag & 1 cup scoup of a mix of hemp litter, fine coco fiber, & biochar I use as my litter.
When I received my Trelino, I set it up in my bathroom and used it for a week. Using 1 cup of vinegar in the bottle then spraying the urine collector area with the ordor neutralizer eliminated odors. I also purchased the urine collector red plug that was reinserted after use. My litter mixture above, 2 cups initial then 1 cup to cover worked to cover up any poop odor.
I like that I can put in a fresh bag 2 cups of litter & put 1 cup in the urine bottle when we leave for a trip. That way it is all ready to put out & use with no setup. We are overlanders who go on trips ranging from 1 night to 1 month at a time. I am glad the Trelino, being ready to go & so easy to use eliminates even having to use a shovel to dig a whole for a quick stop. I have a side mounted quick open g close privacy shower/toilet tent mounted to my roof rack so it & the Trelino make a quick rest stop.
