The diverter does the work
Urine-diverting

The diverter does the work

Urine goes one way, solids the other. Because they never mix, there is no sewage and no smell, no chemicals needed.

Agitation & Aeration
Built-in agitator

Agitation & Aeration

The front-mounted agitator mixes solids. Faster breakdown, smaller volume, fewer empties — two people get 2–3 weeks of full-time use.

Nothing to see here
Drop zone & LED

Nothing to see here

A solid cover hides the solids bin, and the largest drop zone in its class means no awkward aim. The LED urine indicator tells you when to empty, so you never find out the hard way.

Install it or take it with you
Portable or permanent

Install it or take it with you

Cuddy mounts flat against any wall and the lid still opens fully — it fits where others can't. Or leave it loose and carry it to the next campsite.

The science, simply explained

How it
actually works

Urine diverted automatically
01

Urine diverted automatically

The built-in diverter sends liquid to a dedicated 6.5 litre bottle. Liquid and solid never mix.

Coco coir accelerates breakdown
02

Coco coir accelerates breakdown

A layer of coco coir in the solids bin kickstarts natural composting and controls moisture.

Agitator mixes & dries
03

Agitator mixes & dries

A front-mounted handle turns the agitator, cutting volume and speeding up decomposition.

Fan + carbon filter = no smell
04

Fan + carbon filter = no smell

A 12V fan pulls air through refillable activated carbon. Odour goes away from the seat, not toward you.

Very quick and easy to shop. I actually have 2 other composting toilettes. One was VERY spendy. The shopping as well as usage experience was very much worth it.

We love our Cuddy Lite for our "shack on a puddle" that is our version of a cabin on a lake. its perfect for our inconsistent use with the included bags. We are looking forward to the self sealing adapter next year. Thanks Compo Crew!

Thanks Leah!

Great lid, very nice and really sturdy. I step on it to climb onto my bed and it doesn’t move. I don’t regret this purchase at all.

Thanks Alex! Your set-up looks great!

After looking at reviews of many kinds of toilets for out camper build we decided the Cuddy looks like the best one for us, so we bought one.

Last night I wanted to show our Cuddy Compo toilet to someone. As I was carrying it to the kitchen I stubbed my toe, lost my balance, and went flying. I dropped the Cuddy and it sounded like it fell apart! I fell on it, cut my eyebrow and loosened a tooth.

When I checked the Cuddy only the lid was off. It was tight to get back on but it’s as good as new. You can’t tell it had a big adventure. I think that’s a good testament to high quality

Gerry Popplewell

Bottle works great no odor easy to empty, drain cap could be a little stronger, so far no complaints we love our Cuddy Lite.

Thanks Gerry! What a beautiful space you have! Looking good with the Bamboo Lid too!

Here at Beloved Cabin Homestead & Stay we have some of the more popular and recognized toilets made by six different composting toilet manufacturers.

After organizing 32 tiny houses festivals since March 2016, and hosting 1000’s of guests from around the world here on our homestead with our 11 unique getaways of tiny houses on wheels, yurts, geodesic domes and a bus conversion… we can say with honesty and much experience the CompoCloset is our most favorite portable composting toilet.

The CompoCloset combines all the best qualities of the 12 composting toilets we have here on our 16-acre homestead, while at the same time not including any of what we dislike about all the other composting toilets we own.

By far, the CompostClost is the most high-quality, convenient, reliable and portable composting toilet we have ever used over the past 15 years.

8 years into full-timing in a tiny trailer without a bathroom, Covid convinced me that we really should have our own private loo. We upsized to a 16'9" trailer with a toilet and shower, and replaced the flush toilet with a composting version before ever using it (black tank, ew). That was just over 2 years ago and we're so happy with Cuddy!

-It doesn't need to be vented (expect condensation, it's okay!). I don't love the idea of drilling more holes in my house. You can if you want to, but I didn't.

-It takes up less space than the flush toilet it replaced. My husband can sit without his knees hitting the door in our corner bathroom. Not having an awkward space to clean behind the toilet is a bonus. It's Velcro'd in place so I can remove it when I'm in deep cleaning mode.

-We're in the desert about 80% of the time. Water is scarce and expensive. Composting is a no-brainer.

-It really doesn't smell. As I don't trust myself not to get used to anything, every once in a while I have a friend- a real, brutally honest friend, the kind who'll tell me when I have spinach stuck in my teeth- do a smell check. Cuddy passes. One of those friends now has one in her van.

-Cleaning isn't a big deal. I'm not saying it's not a task, but it's not as gross as some might think, and having a water-free waste system is worth it to me. The body of the toilet itself is easy to keep clean on a daily basis, as it's mostly smooth surfaces without a ton of nooks and crannies. I empty the pee bottle as part of my morning routine, but it's usually less than half full at that point. After emptying, I pour in a small amount of white vinegar and swish it around. About once a week I do a more major vinegar and water rinse (water is precious). To empty the bucket, I put a composting trash bag over the whole thing, then turn it over to dump. In circumstances where we don't have access to trash services, I use the kitty litter scooping method and bury the waste. Every once in a while, I do the whole deep clean the bucket thing, which consists of spraying cleaner, letting it sit, using a stick to scrape what needs to be scraped, spraying cleaner again, then wiping it out. I don't actually think this is necessary, but I'm a bit of a clean freak. Of course I wear gloves while doing any of this.

-From a resale standpoint, nothing about the trailer had to be compromised. I capped off the water supply, put a plug in the toilet flange, and built a low plinth to set the toilet because the flange isn't flush with the floor. Any future owner can easily reinstall a flush toilet if that's what they want (and we can transfer Cuddy to our next home).

Long story short, we love Cuddy and will purchase another if we ever move into another camper and our current one goes with it!

Much better than the Trelino I used to have which was basically just a bucket

I’m an Off-Grid Upfitter, we travel in a 30’ Class A motorhome and our first upgrade was swapping out the OEM RV toilet for the Cuddy Composting Toilet. We've used composting toilets for over 6 years and were happy with our previous one however we are always looking to see what's out there and the Cuddy caught our attention due to some really outstanding features:
- Compact without feeling like a bucket: RV bathrooms are tiny, even in larger RVs but at 15" x 17" it doesn't take up much floor space.
- Wall-Hugging: The Cuddy’s got a clever hinge design so you can place it right up against the wall. No wasted space, no awkward angles.
- Pee Tank Light: Ever overflowed a pee tank in the dead of night? We have! The warning light shines bright before it overflows and has already saved us!
- To Vent or Not to Vent? We've tried both with no smell either way. We did eventually vent for more winter moisture control though.
- Opaque Urine Tank: It’s black and does not show off the urine colored content when you adventure out to dump it. Everyone loves a little mystery.
- Interior Solids Bin: Removing an interior solids bin rather than disassembling the toilet and taking out the base to empty was something we did not consider a big deal in our research but in real world use it made life a lot easier and saved time. A definite plus!

These toilets are great for smaller RVs like vans and truck campers we don't feel we had to make any compromises using the Cuddy instead of any other composting toilets

For anyone reading this that travels in a larger RV and your wondering why you would want to go this direction:
It frees your black tank making room for more grey water storage and we all know how fast the grey tank fills up!
No flushing required so your fresh water lasts longer.
These things are sturdy and well designed; We put it through the wringer, and it is holding up without any issues.
We love our toilet and feel confident recommending them to our upfitting clients.

Just what we needed; easy to use, NO SMELLS

This is the second Cuddy I’ve purchased. I installed the first in our garden office and loved it so much I decided to get one when we got our new RV! We found the Cuddy from the vanlife movement. It is only 24 lbs so easy for me to move, but that's not really necessary. It is small, but big enough to be comfortable.Unlike other composting toilets with agitators, Cuddy is easy to maintain. No picking it up to empty, no costly cassett. NO SMELLS! Cuddy has a sealed liquid container that is easy to lift in and out of the Cuddy. Just lift it out, then empty it in a regular toilet, or pour in an isolated area (which will kill weeds and deter unwanted animals.) I also like the addition of the LED for the pee bottle - no guessing when a scummy bottle is full and getting it wrong!The solids container is also super easy. We use sawdust, but others use coco coir, or bedding pellets. The agitator makes it really easy to mix without making a mess, and there's really no smell! We put the toilet paper into a seperate sealed container lined with a plastic veggiebag from the grocery store, and then into the garbage or compost pile.  Separating toilet paper is common in Mexico, the Dominican Republic, and Caribbean islands we have visited, so it's not a big deal. We dispose the solids right into the regular garbage. The bin is easy to lift out, dispose into a garbage bag, then right into the garbage. It can also be recycled in a long-term composter.Everything is really well thought out - the size, the seat, access hinges, Carbon Filter, urine diverter. And, their customer service is great. I had questions about the solids materials and they got back to me right away. They also have cute YouTube videos showing the Cuddy out in the wild.  Cuddy is just the best and I can't recommend it enough!

John digs road trips.

My wife and I tried it out for the first time on a two week road/ski trip to Colorado. We were also trying out our new homemade little travel trailer lol. I was a little nervous about composting toilets but the Cuddy worked great! The quality is good and it's easy to live with, empty, clean and all the things I was worried about. Looking forward to the next trip!

Common questions

We’ve heard it all

Does it smell?

No. Composted material looks and smells earthy, like a forest floor. Urine and solids are separated so no sewage smell is ever created.

Do I need to drill holes in my van?

No. Cuddy works without venting, thanks to its built-in fan and carbon filter. If you use it full time, we recommend venting it outside, or adding the Venting Carbon Filter if you’d rather not drill.

What goes in the solids bin?

A small amount of coconut coir or wood shavings to start the composting process. No chemicals, no special products.

What is the difference between Cuddy and Cuddy Lite?

Cuddy has an agitator and composting system, better for full-time and extended use. Cuddy Lite uses bags instead, with no agitator — simpler and great for part-time use.
