Cuddy FAQs


  • Anywhere you like!

    Cuddy is perfect for vans, campervans, RVs, Tiny Homes, off-grid cabins, boats and more.

    Its size, shape and portability make it suitable for anywhere you need to poop.

    Check out some example toilet use cases for Cuddy and Cuddy Lite.

  • Cuddy's internal fan runs off of 12V, and includes the parts to be hard-wired via a 5.5 x 2.1mm plug, or you can plug it into the mains with an adapter. If you want to move Cuddy around, that's easy too. You can get a 12V DC port plug merit plug adapter, or a USB to 12V Cable with a 5.5 x 2.1mm plug. Cuddy can go just about anywhere and is very efficient, drawing less than 0.3 amps.

    It is ok if Cuddy is not connected to power all the time.

    Cuddy does not need to be connected to power while in storage. For the "pee full" indicator, Cuddy uses a 9V battery (not included).


    Watch Cable Options for my Cuddy for more information about Cuddy’s power requirements.

  • A compost medium like coconut coir is our favorite. Add the medium the solids bin covering the bottom of Cuddy's agitator arms, and off you “go”!  

    Learn more about different mediums to use in composting toilets.

  • No, composting toilets do not smell when used properly. They will not stink out your van, boat, tiny home, camper, or cabin.

    The compost material looks and smells earthy—like a forest floor. When emptying the toilet, there is no unpleasant odor, unless you’re one of those rare folks that don’t like forest floors.

This product is fantastic, I’ve travelled a lot in various camper vans and can honestly say that no toilet facility has come close to being as well designed all the convenience without the chemicals love it! 😊

Awesome! Zero smell!!!

I was skeptical that any composting toliet wouldn’t smell. But, wow! The Cuddy has NO ODOR at all. The Cuddy is so easy to use and to empty, far easier than our former cassette toliet, which smelled like a sewer ever since formaldehyde, as a component of toliet chemicals, was outlawed. Since we go to very hot places we decided to routinely add 4 Polident denture cleaning tablets to the urine bottle after each time we empty it. Doing so eliminates any slight odors. And, the tablets are cheap, $6.00 for 120 tablets. We also decided to buy another urine tank to extend the time in between urine dumps, in case we weren’t somewhere we wanted to dump the urine. Not a big investment but offers more peace of mind.The Cuddy is very solidly built. Its functional simplicity demonstrates a design which is clearly very well thought out.The customer support is amazing, calming my pre purchase anxiety by answering lots of questions about whether or not this toliet was too good to be true.The price is more than fair, especially when considering the other non bucket sophisticated toilet alternatives. Plus it has the smallest foot print of the composting toilets, a key need in our Sprinter van. Yet it doesn’t feel small when using it.We put it in a sliding drawer that fits underneath our bed. Cuddy’s coiled power cord makes it easy to use with our sliding drawer. This is one example of the thought put into the toliet’s design.The toliet hole through which one poops is huge, no chance for messy accidents. The gently tilted tray area that channels urine into its bottle is also large, both great functional design features.The fan uses extremely little power and is almost silent. We don’t see the need to vent it externally, since it doesn’t smell without doing so.The carbon filter is easily replenished, something that is needed very infrequently.The agitator is super easy to use and its placement in the front of the toliet is ideal for use in our sliding drawer.The toliet lid is designed in such a way as it could open flat to a wall behind the toilet, another key space saver.Getting out the urine canister couldn’t be easier. Emptying it is as simple as opening up the lid, pulling out the urine container and unscrewing a small lid. The poop container also just lifts out from the open lid, so much easier than other toilets.It’s a great toliet and a great company. I’d definitely buy it again.

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!
