Trelino Canister is Reliable

I found the Evo M urine canister easy to use as it never leaked and the handle was secure for carrying and emptying. The seal in the lid kept odors from escaping. Trelino customer service is great!

Love it, outstanding toilet.

if there was one thing I would change on the urine canister I would have it bevel up to the lid for easier dumping and cleaning..

The No-Nonsense Straight Poop on Composting Toilets

Got it—here’s a tight, no-fluff version:

The **Trelino Evo** is the first budget composting toilet that actually makes sense in an RV/van/off-grid cabin. Two chambers keep things simple: liquids to a sealed, opaque bottle; solids to a lined bucket. After each use, add a small scoop of dry material (fluffy coir works best). Setup takes minutes, cleaning is a quick vinegar-water spritz, and the smooth surfaces don’t hold odor.

**Why it works:** don’t mix, keep it dry. Separation prevents urine funk; the cover layer keeps solids aerobic. The gasketed bottle is discreet and smell-tight.

**Pros:** fast setup, low odor, easy cleaning, budget-friendly.
**Cons:** you must empty liquids routinely and keep cover handy.

**Bottom line:** Set the habit, and it disappears into the background. I recommend the **Trelino Evo**.

Trelino Evo Medium

This is my second Trelino toilet that I am using in my new van build. Obviously I loved my first toilet because of its simplicity, low environmental impact and functionality.

This time Trelino charged me for my entire order to be shipped to my van builder but did not ship my entire order. I am dissatisfied with customer service as there is no US telephone customer service. While Trelino eventually resolved their shipping error, the resolution was cumbersome and prolonged due their lack of any direct customer service presence in US. The only communication option is via generic email made even more untimely by the large time zone difference. I would not order directly from them again unless they offered direct customer service in US.

Very good quality

The unit is compact, very sturdy, and easy to use. Stable and no smell issues. I'm looking forward to a long happy relationship with my new loo!

Not Crappy

I bought this small unit for my Honda odyssey. It is the perfect size both in width and height. I am 5'11" and weigh 244 lbs, yet I have no problem to use this in the privacy of my van. It has been a game changer especially late at night or early in the morning when I am stealth camping. Clean-up is easy-peasy... Turtle6565 recomends....

Must Have Extras

this is a must have in the back up category because without it you will have spray and clean up, odor, etc. the unit is not useable (in my view) without it so I’m happy they sell extras!

Outstanding quality, simple, effective

Super happy with purchase of large compost able toilet from Trelino. Using in my rv when I go visit my dad as there is no viable septic where he's located. Comfortable, and as a female I HIGHLY appreciate that it is ergonomically designed to meet my basic needs. Functional, high quality, and a good price.

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!

YES! Simple and effective

We have been using our Trelino living Full-time in our truck camper for the past 2 years, and we’ve overfilled it on a number of occasions. But no more! Now we know when it’s time to dump without having to open the top. It just works. Thats it.

Excellent product

Great product, sturdy and plenty of capacity.

Gave it a try star because of price and the rubber diverter doesn’t sit securely and felll into the urine tank! Otherwise works like intend!

It’s great, does what it’s supposed to do

Not value for price

For what this cost it should be as good as original and this definitely not German engineering. Looks like something from dollar tree. Not very happy. M Hemmens

Hello Mike,

Thank you for taking the time to leave your feedback. This white urine canister is for the Small Origins. It looks like you have the Medium Origin. The spare Medium urine canister would be the same blue item as the one that is included with your Medium Origin.

We would be happy to help get you the correct item for your toilet! Also to get any feedback on how we can better differentiate the two items on our product pages.

Best,
Your Trelino team

Best Camping Toilet

After trying a few different types and after reading a great review from Treeline Review by Sia Lizard, I bought this great camping toilet. I'm a firm believer in the KISS concept, this one is a no brainer. Sleek and compact, soft close lid, no leak urine container and easy to manage poop container, this is a dream to have in my camper van. Feel free to adventure anywhere, this toilet allows you to be out there without worrying about where to go.

Too flimsy

The membrane closures are too flimsy and keep falling through the hole. Not fun having to fish them out of urine or lose them while dumping.

Work well

These work well. I thought it would be nice to have an extra.

Pretty Great.

Overall, I think these things are great and customer service is very responsive. I would have given it five stars except this review is after having to have it replaced because the original cracked after just a few uses. But they replaced basically with no questions asked. I just sent them an email with some pics and they got back to me right away. I had a new toilet within a week. Thanks.

No more worries!

The meter lets you know when the urine part of the toilet needs emptied. Prevents any chance of over flow. I was skeptical, but it works. A

EXCELLENT!!!

Thank you so much for creating the urine canister lid with membrane, it was much needed for I that part had fallen out of my van and was therefore lost forever. I was so excited when I heard that you were making replacements. Thank you for taking care of your customers and God bless you all!

Work well

Way more convenient than huge industrial strength trash bags!

Awesome

After using one that used water in a waterless area it is the best!

Works great

Great little addition to make sure you don’t have than unexpected overflow. Easy install and works as described

Nice that the membrane closures are available. Nice that they work so well at making this toilet odor free. Not so nice that they don’t tell you they need replaced every few months. Wish I knew this when I ordered the toilet, as it would have saved me the $20 shipping fee.

Game Changer

I no longer have to worry about how full my pee jug is! This is the best thing you can add to your toilet. The days of overflowing pee jugs is over!
