Choosing the right toilet for a caravan or off-road hybrid is one of those decisions that seems minor on paper but becomes very important once you’re actually living in the van. As more travellers push further off-grid and look to reduce reliance on dump points and chemicals, alternative toilet systems have become far more common. Three names consistently come up in buyer conversations: the Thetford Separation toilet, the OGO Origin composting toilet, and the Clesana C1 waterless sealing toilet. While all three aim to solve the same problem, they approach it in very different ways, and each comes with real-world trade-offs that matter once you start touring.
The Thetford Separation toilet is often the most practical option for the majority of caravanners because it delivers meaningful improvements over traditional cassette toilets without introducing unnecessary complexity. By separating liquid and solid waste, odour is dramatically reduced and the need for chemical additives is largely eliminated. From a user perspective, it still feels like a normal caravan toilet, which means there is almost no learning curve. Servicing and maintenance remain familiar, access panels and footprints are consistent with existing Thetford systems, and day-to-day use doesn’t require any special routines. This balance between improved hygiene, reduced smell and practical usability is why many modern caravan manufacturers are now standardising separation toilets in new builds. In our 2026 caravan range, the Thetford Separation toilet is fitted as standard because it provides the best overall ownership experience for most customers, particularly those who want a reliable, low-fuss system that works just as well on powered sites as it does off-grid.
The OGO Origin composting toilet appeals to a different type of traveller. It is designed for people who are committed to long off-grid stays and are comfortable managing a more involved waste system. Composting toilets separate liquid and solid waste, then rely on airflow, agitation and bulking medium to manage solids over time. When set up correctly and used consistently, they can work well, but the experience is highly dependent on user behaviour and ventilation quality. In real-world use, composting toilets tend to suit slower travel styles where the van stays in one location for longer periods. For owners who move frequently, stop overnight, or don’t want to think about waste management as part of their daily routine, composting toilets can feel like more effort than expected. They are a good fit for a specific type of off-grid user, but they are not always the most practical solution for general touring or family use.
The Clesana C1 waterless toilet is positioned as a premium, convenience-focused option. Instead of separating or composting waste, each use is sealed into a high-barrier liner, effectively locking away odour and contact with waste. From a day-to-day user perspective, this is often the cleanest and most hygienic experience available in a caravan toilet. There is no compost medium to manage, no liquid container to empty, and no traditional dump point routine. This makes the Clesana particularly appealing for families, guest use, or situations where multiple people are using the van. The trade-off is that the system relies on proprietary liners, creating an ongoing consumable cost and the need to manage stock when travelling remotely. The unit also draws electrical power during sealing cycles, which needs to be factored into the caravan’s electrical design. For owners who value convenience and cleanliness above all else, the Clesana C1 is an attractive option, but it comes with higher upfront and ongoing ownership costs.
In practical terms, the differences between these three toilet systems show up in everyday touring rather than on specification sheets. The Thetford Separation toilet tends to offer the best balance of simplicity, hygiene and reliability for most caravan owners, which is why it has become the standard fitment in our 2026 caravans. Composting toilets like the OGO Origin reward careful setup and consistent habits but are less forgiving of casual use. Sealed-liner systems like the Clesana C1 offer exceptional cleanliness and odour control but introduce ongoing consumable costs and higher system complexity.
There is no single “best” caravan toilet for everyone, but there is a best choice for how you travel. For most touring families and couples who want minimal fuss, predictable servicing and a modern, off-grid-capable solution, separation toilets represent the most balanced option. That is exactly why we chose to engineer our 2026 Cub caravans around the Thetford Separation system as standard. It delivers the everyday usability people expect from a premium caravan, without asking owners to change how they camp or manage their waste.
