Simple and Hygienic Emptying
To empty the waste tank, detach it from the toilet and carry it to the nearest approved waste disposal point. Twist the integrated emptying spout outwards, unscrew the cap and press the vent button. Allowing air into the tank helps control the flow and reduces the chance of splashing while you pour the contents away.
The separate waste tank also makes routine cleaning and maintenance easier, particularly when you use the toilet on a boat or in a compact recreational vehicle.
Toilet Additives and Paper
For reliable operation and optimum performance, Thetford recommends using its specially formulated toilet additives together with rapidly dissolving Aqua Soft toilet paper.
The toilet additives help prevent unpleasant odours, suppress gas formation and keep the inside of the waste holding tank clean. They also support the breakdown of solids, helping reduce the risk of blockages when you empty the tank.

Important Information
Always dispose of toilet waste at an approved waste disposal point. Follow local regulations and use suitable toilet additives and rapidly dissolving toilet paper to help protect the system.
Check the available storage space before purchase. The toilet measures 330 mm high, 383 mm wide and 427 mm deep, and you should allow additional room for removal and cleaning of the waste tank.
Boat Hut Insight
On a boat, the best place for a portable toilet is often the spot you can reach at night without stepping outside. Before buying, measure the route to that storage location as well as the cupboard itself. A toilet that fits perfectly inside may still be awkward to remove through a narrow cabin doorway, especially when the waste tank needs carrying for disposal.
Helpful Usage Tips
- Measure both the storage compartment and the route you will use to remove the toilet.
- Keep the toilet level during transport to reduce the risk of spills.
- Use the recommended additive at the correct dosage for the waste tank.
- Choose rapidly dissolving toilet paper to help reduce the risk of blockages.
- Empty the waste tank before storing the toilet for an extended period.
- Clean and rinse the waste tank regularly, especially after use in warm weather.
