Really. Urine and solids never mix, so there’s no sewage smell to start with. Cuddy also pulls air through a carbon filter with its built-in fan. At worst you’ll notice an earthy smell from the coir. The urine bottle will smell when you open it to empty it. That’s urine for you.

Cuddy is our original self-contained composting toilet for long trips and full-time use: agitator, urine indicator light, carbon filter, multiple venting options. Cuddy Lite is the same no-smell separation, simpler and budget friendly. S1 is for people who never want to see or handle anything. It comes two ways: as the S1 12V, which wires into your rig’s 12V system with nothing to charge, or with its own battery.

Liquids: pour down any toilet, dump station, or by a mature tree. Solids: always check the rules for your location. Usually solids from composting toilets may be bagged and put in a regular trash bin.

Liquids every 2–3 days for two people. For solids: Cuddy every 2–3 weeks, Cuddy Lite every 8–12 uses (tie off and swap the bag), and the S1 every 2–3 uses. Compare that to a chemical toilet: every 2–3 days for everything, at a designated dump point.

Yes. There’s no flush water to slosh around. The urine bottle has a one-way valve, so nothing comes back out on rough roads. Just secure the toilet so it can’t slide. Our portable toilets are used on sailboats, narrowboats and overland rigs.
