Composting toilets (like Cuddy) use natural processes to break down waste without water. Liquids and solids are kept separate: urine goes into a bottle, while solids mix with a natural bulking agent and begin to compost. An agitator helps keep things odor-free and easy to empty. Perfect for vans, boats, cabins, and tiny homes.
Dry flush toilets (like the S1) don’t compost. instead, each use is automatically sealed in a bag, locking away odors. Urine is diverted separately, and sealed packs are removed when full. Quick, hygienic, and low-maintenance, ideal for travel or when you want simple, mess-free waste management.
Camping toilets often fall short, but not Cuddy. With the size of a tiny chemical toilet, Cuddy offers special features that make your Life & Adventure easier.

Better Toilets for People & The Planet
Why not the best? Because even the best can always do better - and we're never going to stop innovating
We believe composting toilets are superior to chemical toilets in terms of user experience, safety and the environment.
We often get asked this FAQ!
No, composting toilets do not smell when used properly. They will not stink out your van, boat, tiny home, camper, or cabin. The composted material looks and smells earthy - like a forest floor.
When emptying the loo, there is no unpleasant odour, unless you’re one of those rare folks that don’t like forest floors.
Another common FAQ.
Yes, composting toilets need emptying but much less frequently than chemical toilets.
From our experience, composting toilets are much less unpleasant to empty than chemical toilets because they don’t have an unpleasant smell and the solids simply resemble dirt.
Always check the rules that apply to your specific location.
Usually, solids from composting toilets may be put in a biodegradable bag and disposed of in a regular rubbish bin. In general, the law permits disposal of human waste in this manner to due to the need to dispose of baby and adult diapers, as well as pet waste.
If you have a space to do so, you might consider continuing the composting process that Cuddy started. There are several resources for how to compost and use human manure. We like The Humanure Handbook as a starting point. Urine can also be used as a fertilizer - the Rich Earth Institute is a good resource about peecycling.
Our toilets are specially designed to make emptying as quick and easy as possible. The solids bin is simple to remove and empty, and liquids from composting toilets can be poured down a regular toilet or onto the nearest thirsty looking mature tree.
Yes, you can pee in a composting toilet.
Our composting toilets are designed to separate the pee from the poop to eliminate any nasty odours.
Yes, you can put a composting toilet in an RV. It is a great way to save water, space and not deal with nasty chemicals.
The solids section of Cuddy typically needs emptying every 2-4 weeks depending on how much it’s been used.
You can look into the chamber to check the level. We would advise emptying when the chamber is around two thirds to three quarters full.
The LED light will let you know when the liquids bin is ready to be emptied.
We don’t recommend this because food scraps will attract flies and other insects.
