Clesana C1 Waterless Toilet with Round Base

Total freedom. Zero compromise.

The Clesana C1 with Round Base is a new generation waterless toilet system designed for modern campervan conversions, off-grid builds, boats and expedition vehicles.

No water. No chemicals. No cassette waste.

Using advanced thermo-pressure sealing technology developed in Switzerland, the C1 hygienically seals waste into odour-proof barrier film bags, creating a cleaner and more convenient alternative to traditional campervan toilets.

Every use is automatically sealed and contained inside a hygienic multi-layer liner, eliminating the need for flushing water, chemical additives or messy cassette emptying.

This is sanitation reimagined for modern van life.

Designed for custom installations.

The Round Base version is designed for standalone floor mounting applications, making it perfect for bespoke campervan conversions, off-grid vehicles, tiny homes and marine installations.

Unlike traditional cassette systems, the C1 does not rely on external access doors, black waste tanks or plumbing infrastructure. Its compact footprint and flexible mounting options allow you to design your interior without compromise.

Minimal systems. Maximum freedom.

Cleaner by nature.

The C1 removes many of the frustrations associated with conventional campervan toilets.

No searching for disposal points.
No carrying chemicals.
No flushing water usage.
No unpleasant emptying process.

Instead, waste is securely sealed into hygienic odour-proof bags for simple disposal when convenient.

The result is a cleaner, more comfortable and more practical experience both on and off-grid.

Engineered for modern van life.

The Clesana C1 operates directly from a standard 12V electrical system and integrates perfectly with modern lithium and solar-powered campervan setups.

Efficient power consumption and minimal maintenance requirements make it ideal for extended travel and off-grid living.
