    Our Mission

    At CompoCloset, our mission is simple:

    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.

    But we're always developing new ideas...

    We've heard it all. Here's the honest version.

    No marketing spin — these are the real answers we give in support emails.

    Does it really not smell?

    Really. Smell comes from liquids and solids mixing — Cuddy and Cuddy Lite and the S1 keep them separate (with an optional carbon filter scrubbing the air). In a sealed van, you won't smell it. The urine bottle will smell when you open it to empty it, like any toilet would.

    Cuddy, Cuddy Lite or S1 — which one is for me?

    Cuddy our original self-contained composting toilet perfect for long trips and full-time use: agitator, urine-level sensor, carbon filter, multiple venting options. Cuddy Lite is the same no-smell separation, simpler, budget friendly — great for weekenders. S1 is for people who never want to see or handle anything: push-button dry flush that seals each use into a cartridge. Still unsure? Use the "Help me choose" quiz above.

    What do I do with the waste?

    Liquids: pour down any toilet, dump station or by a mature tree. Solids: Always check the rules that apply to your specific location. Usually, solids from composting toilets may be put in a bag and disposed of in a regular trash 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. Read more

    How often do I empty it?

    Liquids every 2–3 days for two people. For solids, we advise the following per model: Cuddy: 20-25, Cuddy Lite: 10-15, S1 Dry Flush: 2-4. Compare that to a chemical toilet: every 2–3 days for everything, at a designated dump point.

    Can I use it while driving / on a heeling boat?

    Yes — there's no water to slosh and the bins are sealed. Our portable toilets are used on sailboats, narrowboats and overland rigs.
