Clesana C1 Waterless Toilet – Swiss-Engineered, Chemical-Free Toilet System for Caravans & Off-Grid Living
Ready to ditch chemicals, water use, and dump points then the Clesana waterless toilet offers a completely different way to manage waste in your caravan, campervan, or off-grid setup.
Instead of flushing into a black tank, Clesana seals waste in heat-welded sanitary bags, locking in odour and mess so you can simply dispose of it in your general rubbish.
It’s a cleaner, simpler and more hygienic approach to going to the toilet on the road.
Engineered in Switzerland, used in demanding medical environments, the Clesana waterless toilet system is now available to Aussie travellers from Everything Caravans.
With no chemicals, no water, and no need to visit dump points, it’s an ideal cassette toilet alternative for anyone who wants independence and the least hassle when travelling or living off-grid.
Clesana is a brand built on Swiss engineering, medical-grade hygiene and a complete rethink on how to manage waste in mobile and off-grid environments.
Clesana technology was originally developed in Switzerland in 2009 as a safer toilet solution for hospitals, designed to protect staff from exposure to pharmaceuticals and pathogens. Instead of flushing, the system seals waste in heat-welded sanitary bags – no contact, no splashes, no aerosols, and no contaminated surfaces.
Clesana focuses on giving travellers, off-grid homeowners and remote workers a toilet solution that feels premium and hygienic. In Australia and New Zealand, Clesana is proudly distributed by Portable Innovations Pty Ltd, making this Swiss innovation easily accessible and fully supported locally.
When you choose a Clesana waterless toilet through Everything Caravans, you’re not just upgrading a toilet – you’re choosing a brand that has been engineered from the ground up for safety, cleanliness and sustainable off-grid independence.
How the Clesana C1 Waterless Toilet Works
The heart of every Clesana waterless toilet is a simple idea: instead of flushing waste away with water and chemicals, you seal it safely out of sight – and out of smell. Inside the Clesana C1, medical-grade, bio-based liner film forms a fresh “bag” for each use. After you’ve finished, you simply close the lid and press the button. The system then uses controlled heat and pressure (thermal welding) to seal the bag around the waste, creating an airtight, odour-proof package. There’s no black tank to empty, no chemicals to handle, and no liquid waste.
From the user’s point of view, the process is fast and intuitive. You sit and use the C1 just like a standard caravan toilet. When you’re done, you press the activation button and let the unit do its work – in just a few seconds, the waste is compressed, welded into a secure pouch, and automatically stored in the internal collection area. Once the collection area is full, you open the access hatch, remove the chain of sealed bags, and place them into your general rubbish. Because each package is hygienically sealed, there are no spills, splashes or unpleasant odours when handling or disposing of them.
This closed-bag system is what makes Clesana so different from cassette, chemical and composting toilets. By keeping waste completely contained from the moment of use to final disposal, the Clesana C1 offers a cleaner, more hygienic and more convenient way to manage toilet waste in caravans, campervans, tiny homes and other mobile or off-grid setups.
Key Benefits for Caravans & RV Owners
The Clesana waterless toilet is all about making life on the road simpler, cleaner and more independent. By sealing waste in individual, heat-welded sanitary bags, you eliminate the need for tanks, cassettes, chemicals and regular dump-point visits. That means no more timing your travel days around finding a dump station, no more dealing with hoses and cassettes, and no more worrying about smells building up in your van. Instead, you get a straightforward “use, seal, bin” routine that fits easily into everyday touring or long-term off-grid living.
Hygiene is another major advantage. Because the Clesana system seals waste in medical-grade liners, you never have to come into contact with raw waste or contaminated surfaces. Each use is isolated in its own odour-proof pouch, so there are no splashes, leaks or lingering smells when you empty the collection area. This makes the Clesana C1 especially appealing for families, full-time travellers and anyone with health concerns.
Clesana gives you greater freedom to camp where and how you want. With no reliance on water for flushing, no chemicals to buy and store, and no dump points to locate, it’s easier to free-camp for longer and explore more remote locations with confidence.
Whether you’re travelling for weekends or living in your caravan full-time, the Clesana waterless toilet helps you stay comfortable, self-sufficient and in control of your own waste management – without compromising on convenience or cleanliness.
Built to Last: Durability and Power
A major strength of the Clesana waterless toilet is how robust and reliable it is for real-world travel. Built to commercial-grade standards, the Clesana C1 is rated for over 22,000+ cycles, giving you years of dependable use in your caravan, campervan or tiny home.
The internal components are engineered to handle regular travel vibrations, temperature changes and day-to-day wear, so you can trust it to perform whether you’re on corrugated outback tracks or parked up by the coast. This durability makes Clesana a serious long-term alternative to traditional cassette and chemical toilets, not just a niche or experimental option.
Because the Clesana C1 is 100% waterless, there’s no need to plumb in a flush line, no moving water parts to maintain, and no risk of leaks from a flush tank or toilet bowl. This not only simplifies installation, it also frees up valuable fresh water capacity for showers, drinking and washing.
In practical terms, that means less time topping up tanks and more time enjoying your trip. Power use is modest and predictable, with each sealing cycle drawing a short burst of energy to complete the thermal weld. For most caravan and RV setups with a standard 12V system and a reasonable battery/solar arrangement, the Clesana waterless toilet integrates smoothly without putting undue strain on your power budget.
Day-to-day operation is designed to be as simple as possible. A single push button starts the sealing cycle, and clear indicators let you know when it’s time to change the liner roll or empty the collection area.
Maintenance is minimal, keep the unit clean as you would any premium toilet, replace consumable liners as needed, and perform occasional checks as outlined in the user manual.
With no valves to unblock, no chemical tanks to rinse and no cassette system to service, the Clesana C1 offers a hassle-free ownership experience that suits both casual travellers and full-time off-grid users.
Clesana vs Cassette & Composting Toilets
When you compare the Clesana waterless toilet with a traditional cassette toilet, the differences are immediate in everyday use. Cassette systems rely on water and chemicals to mask odours and break down waste in a holding tank, which then needs to be carried, tipped and rinsed at dump points. That process exposes you to splashes, smells and contaminated surfaces. By contrast, Clesana seals each use in an individual, heat-welded sanitary bag. There’s no black tank to handle, no chemicals to manage and no need to queue at dump stations – you simply place the sealed, odourless pouches into your general rubbish.
Composting toilets aim to reduce water use and chemicals, but they bring their own compromises. They typically require careful management of ventilation, bulking agents and moisture levels to control odour and ensure proper decomposition. In real-world caravan and RV conditions – with temperature swings, limited space and variable use – that can mean more monitoring, more maintenance and more potential for smells if things aren’t perfectly balanced. The Clesana waterless toilet avoids all of this by removing the composting process altogether. Each use is isolated and sealed in seconds, with no need to stir, vent or wait for anything to break down inside your van.
Chemicals and odour: No chemicals required, and odour is controlled by sealed bags rather than chemicals.
Water use: 100% waterless, freeing up fresh water capacity and simplifying your plumbing.
Waste handling: No heavy cassettes, no dump hoses, no compost bins – just sealed pouches that go into general rubbish.
Environmental impact: Bio-based liners, fewer dump-point trips and no risk of untreated waste entering soil or waterways.
Installation in your Caravan or RV
Fitting a Clesana waterless toilet into your caravan or RV is designed to be as straightforward as possible, whether you’re upgrading from an existing cassette toilet or planning a new build. Because the Clesana C1 is completely waterless, there’s no need to run water lines or redesign your plumbing system. In many cases, the unit can be installed in the same footprint as a cassette toilet, with some minor carpentry or cabinetry adjustments to secure the base and provide access to the liner roll and sealed-bag collection area.
For new builds and custom vans, the flexibility of the Clesana system opens up more design options. Without the need for cassette access, you can simplify the layout and reduce weight. The toilet no longer needs to be on an outside wall. Ventilation requirements are minimal compared to composting toilets, and because there is no standing waste in a tank, there’s less concern about odours seeping into your living area. A standard 12V electrical connection is required to power the thermal welding cycle, and your installer or auto-electrician can easily integrate this into your existing power system.
While confident DIYers may be able to install the Clesana C1 themselves by following the manufacturer’s guidelines, many owners prefer to use a professional installer to ensure everything is mounted securely and wired correctly for life on the road.
The team at Everything Caravans can provide advice on suitability for your specific van, layout considerations and recommended installation practices, or install the unit for you.
Specifications and What’s Included
To help you plan your build or upgrade with confidence, it’s important to understand the key specs of the Clesana waterless toilet. The Clesana C1 is designed with a compact, caravan-friendly footprint and a comfortable, household-style seat height, making it easy to integrate into most existing bathroom layouts. Its lightweight construction helps keep your overall van weight under control.
The Clesana C1 is engineered for longevity, with a design life of over 22,000+ cycles. The internal storage area holds a chain of individually sealed bags, and the exact number of uses you get before emptying will depend on how many people are using the toilet and how frequently. Bio-based, medical-grade liner rolls are specifically made for the system and feed automatically to create a fresh bag for each use. When the roll is finished, you simply follow the changeover process outlined in the user manual – a quick, clean task that doesn’t involve touching any waste.
When you purchase a Clesana waterless toilet through Everything Caravans, you’ll receive the C1 toilet unit itself along with the essential components needed to get started. This typically includes a starter liner roll, mounting hardware and user documentation with installation and operating instructions. Everything Caravans also stocks genuine Clesana consumables and accessories – such as replacement liner rolls and any recommended spare parts – so you can easily maintain your system for the long term.
FAQ
How do I dispose of the bags – is general rubbish really OK?
Yes. One of the biggest advantages of the Clesana waterless tiolet is that the sealed bags can be placed straight into your general rubbish. Each use is welded into an airtight, odour-proof pouch made from medical-grade, bio-based film, so there’s no risk of leaks, spills or exposure to raw waste when you’re handling it.
How many uses do I get per liner roll or per bag?
The Clesana C1 works by creating a fresh “segment” of liner for each use, then welding that segment into a sealed pouch. A single liner roll provides many individual uses, with the exact number depending on your settings and how the toilet is used (number of travellers, frequency, and whether you combine liquids and solids). In practice, most touring couples find that a roll lasts for multiple days or weeks of normal use, while families and full-timers will go through rolls more quickly.
What about smells, especially in hot Australian conditions?
Odour control is one of the standout strengths of the Clesana waterless tiolet. Instead of relying on chemicals to try to mask smells in a shared tank, the system prevents odours from forming by isolating each use in its own airtight, heat-welded pouch.
Is the Clesana C1 suitable for families and full-time travel?
Absolutely. The Clesana waterless toilet was designed from the ground up for regular, everyday use, not just occasional weekend trips. Its commercial-grade durability rating of 22,000+ cycles means it can comfortably handle the demands of family travel or full-time living, provided you keep up with normal maintenance and consumables. For families, the push-button operation and “normal toilet” feel make it easy for everyone to use without special instructions or complex routines.
What happens if I have a power issue or run low on battery?
The Clesana C1 needs power to perform its thermal welding cycle and properly seal each bag. The good news is that each cycle uses only a short, controlled burst of energy, so overall power consumption is modest for most caravan and RV setups. In normal use, a well-sized 12V system with decent battery capacity and solar charging will run the Clesana waterless tiolet comfortably alongside your other essentials.
How eco-friendly is Clesana compared to cassette or composting toilets?
From an environmental standpoint, Clesana approaches sustainability differently from both cassette and composting toilets. Cassette systems typically use chemical additives and discharge treated waste into dump points, where it ultimately ends up in treatment facilities or the environment. Composting toilets reduce or eliminate chemicals and water, but they store and process waste on board, which can be sensitive to temperature and moisture and may still require careful disposal to avoid contamination.
The Clesana waterless toilet uses bio-based liners that are designed to break down completely within 3–5 years under typical landfill conditions, significantly faster than conventional plastics. If you want a solution that minimises chemicals, protects the environment and still feels like a premium, modern toilet, Clesana is a outstanding choice.
