Two ways to go
Composting
or dry flush?
Both are waterless, chemical-free and urine-diverting. The difference is what happens to the solids.
Composting = Cuddy and Cuddy Lite. Dry flush = the S1 Dry Flush Sealing Toilet, with its own battery or as the battery-free S1 12V.

We’ve heard it all
Here’s the
honest version
No marketing spin — these are the real answers we give in support emails.
Do they smell?
No, they really don't smell.
Urine and solids never mix, so there’s no sewage smell to start with.
Composting toilets use the composting process to cover and dry out the solids. Just think old dry dog poo - it doesn't really smell anymore. Learn more.
And the S1 - well it seals the #2s into high barrier bags - no smell escaping those.
Cuddy, Cuddy Lite or S1 — which one is for me?
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.
What do I do with the waste?
Liquids: pour down any toilet, dump station, or by a mature tree.
Solids: always check the rules for your location. In most places, the solids, like baby diapers, etc. may be bagged and put in a regular trash bin.
How often do I empty it?
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.
Can I use it while driving, or on a heeling boat?
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.
