-
Traditional dry-flush toilets bag every single use — liquid and solid together. You burn through expensive proprietary refills fast, and you're effectively paying to seal urine in plastic. The S1 diverts liquid into a separate 6.5 litre bottle and only seals solids. That's up to 80% less bag use, dramatically lower running costs, and far less plastic waste. It's the first dry-flush toilet with urine diversion built in.
-
The S1 uses two separate batteries: one for the sealing mechanism and one for the urine level indicator.
1. Sealing mechanism battery
The sealing mechanism runs on the included rechargeable Li-ion battery.
- Charging: Connect the supplied 12V power supply unit (Input 100–240VAC, Output 12VDC/2A) to the power input socket at the back of the toilet.
- Powering on: Use the power switch on top of the battery box.
Safety warnings
- Fully charge the battery before first use.
- Only use the CompoCloset-approved charger.
- Do not connect the power input directly to a source exceeding 12.6V, such as a vehicle alternator or a LiFePO4 battery. For those, use the CompoCloset Li-ion 10–24V DC charger.
2. Urine level indicator battery
The indicator light needs its own 9V battery, which is not included.
- Installation: Remove the two screws on the battery box and fit a fresh 9V battery.
-
Each liner roll gives ~25 uses. For 2 people with regular use, that's roughly every 1–2 weeks. Swap takes under a minute — no tools, no mess. Refills are available on CompoCloset.co.uk
-
The urine bottle holds 6.5 litre. For two people you will empty it every 1-2 days. The LED indicator tells you when.

Good news — you don't need to buy the full S1. The S1 Dry Flush Adapter Kit converts your existing Cuddy or Cuddy Lite into a sealing toilet. Plug-and-play, no permanent modifications required.
-
If you run out of bag liners the S1 has a built-in backup mode — it converts to a standard urine-diverting toilet You're never left without a working toilet.
