Can a Clesana C1 replace my cassette toilet?
In many motorhomes, campervans and caravans, a Clesana C1 can replace an existing cassette toilet—but it is not always a simple one-for-one swap. A good conversion starts with the vehicle, the available space and the existing electrical and structural details.
Why owners make the change
The Clesana C1 is a waterless bag toilet. Instead of storing waste in a cassette, it seals each use into a hygienic liner bag. For many owners, the attraction is greater independence from disposal points, no black-water tank and a clean, familiar seating position.
The six checks that matter
1. Space and clearances
We check the available floor area, wall clearances, seat height and whether the lid and unit can be used comfortably. A room that looks large enough can still have a door, shower screen or furniture edge that affects the fit.
2. Existing cassette opening
Removing a cassette toilet can leave an external service-door opening, fixings or exposed surfaces. The plan needs to cover how these areas will be made secure, weatherproof and visually tidy.
3. Floor and wall condition
The mounting surface must be sound and suitable for the installation. Previous fittings, water damage or hidden services can change the scope once the original toilet is removed.
4. Electrical supply
The C1 needs a suitable electrical installation planned to the manufacturer’s current instructions. Cable routing, protection and the vehicle’s existing electrical system must be assessed before work begins.
5. Access for use and service
A successful installation is not only about making the toilet fit. There must also be sensible access for fitting liners, normal cleaning, inspection and future support.
6. The way you travel
Your touring style matters. Tell us how many people will use the toilet, how long you stay off-grid and where the vehicle is used. This helps us discuss consumables and whether the C1 is the right choice for you.
What happens during a professional conversion?
- We review photographs and vehicle details.
- We confirm the likely fit, any visible complications and whether an in-person inspection is needed.
- We agree the installation scope and price before work begins.
- The existing toilet is removed carefully and the surrounding area is assessed.
- The C1 is installed and connected in accordance with the current manufacturer instructions.
- The unit is checked and you are shown normal operation and consumable replacement.
Can I install it myself?
Clesana recommends purchase and installation through a designated specialist dealer so correct installation, optimum function and the service process are protected. The work can involve vehicle electrics, hidden services and alterations to the washroom structure, so it should only be undertaken by someone competent for the complete scope.
Always use the current official Clesana C1 installation manual. Do not work on live electrical systems or make assumptions about hidden cables, pipes or structural panels.
