Can I discard the barrier liners in my general waste (red bin)?
Yes. These barrier liners are designed for safe disposal in household rubbish. Always dispose of waste responsibly, in line with local council regulations, with respect and care for others.
Can I discard the barrier liners in green/organic waste bins?
No. Barrier liners must be placed in a general waste (red lid bin). The Clesana C1 is a chemical-free toilet and uses barrier film to hygienically seal waste and should not go in green bins.
Are the sanitary bags odour-proof?
Yes. At room temperature, the bags remain odour-proof for 2–4 weeks. In hotter
conditions (above 30°C), we recommend disposal within 48 hours.
Is the toilet ready to use again straight after "flushing"?
Yes, once the sealing cycle is complete, the toilet is ready to use again.
Can the C1 handle more than human waste?
Yes. The C1 can hygienically seal feminine products, nappies, and even food scraps —
making it ideal for off-grid and caravan toilet use. Avoid inserting sharp objects or hot ashes, and don’t exceed the fill line.
Is the toilet 12V only?
Yes. The Clesana C1 waterless toilet operates on 12V DC. It is not compatible with 240V mains power unless a validated converter is used.
How much weight can the toilet support?
The C1 supports up to 150kg when the lid is closed.
Can I retrofit the C1 and replace my cassette toilet?
Yes. The C1 is a great cassette toilet alternative and can replace many existing models. Some layouts may require minor modifications — see our install guide or speak with a certified installer.
Can the C1 be connected to 240V mains power?
Not directly. The C1 requires a validated converter for mains use, and none have been certified for long-term 240V operation at this stage.
Can I power the toilet with a battery?
Yes. The C1 can be powered by a mobile 12V battery system. It’s not a portable toilet
in the traditional sense, but a fixed, battery-compatible unit suitable for mobile setups.
DoI have to seal the bag after every use?
No. You can use the toilet multiple times per bag as long as you don’t exceed the fill line.
Is the absorber powder required?
Not required, but helpful. The absorber turns liquids into gel for easier handling and better hygiene — especially when using the same bag overnight.
