The Thetford Separation Toilet S260S is a complete waterless toilet designed for caravans and motorhomes that separates urine and solid waste at source. This recessed wall-mounted system eliminates the need for flush water and chemical additives, making it ideal for off-grid touring and wild camping. With a 7-litre solid waste bucket and 7.5-litre urine tank made from recycled plastic, it provides a practical alternative to traditional cassette toilets while offering greater freedom from fixed disposal points.
How does a separation toilet work for motorhome off-grid camping?
The S260S separates liquid and solid waste without water or chemicals, storing them in individual containers. The 467mm seat height and ergonomically optimised bowl suits adults and children, while the side-operated blade keeps solids out of sight. Electronic level indication alerts you when the 7.5-litre urine tank needs emptying, which happens less frequently than cassette toilet servicing because liquids and solids are separated from the start.
Installation fits the same footprint as Thetford's C260 cassette toilet, making it straightforward to mount in existing spaces or new builds. The leak-free connection prevents spills when removing the urine tank, and the 4-pole electrical plug powers the electronic level indicator and optional ventilation. Weighing 7.1kg and measuring 488 x 340 x 603mm, it works with optional Door 3 access and Thetford ventilation kit A0032630 for active odour management.
Thetford also offers this system as a conversion kit for existing C220 or C260 cassette toilets, letting you switch to waterless operation without replacing the entire unit. The separation design means solids dry out and produce minimal smell, while the urine tank empties into any standard toilet or grey water outlet. This makes it suitable for longer trips without chemical costs or the need to locate specialist disposal stations, giving you more flexibility in where you travel and how long you stay off-grid.

Frequently Asked Questions
How often do you need to empty a separation toilet compared to a cassette toilet?
Separation toilets require emptying less frequently than cassette toilets because liquids and solids are stored separately. The Thetford S260S has a 7.5-litre urine tank and 7-litre solids bucket. Urine typically needs emptying every 2-3 days depending on usage, while the solids bucket lasts considerably longer as solid waste makes up around 20% of total volume. Cassette toilets require the entire mixed tank to be emptied more frequently at designated disposal points.
Does the Thetford S260S separation toilet smell?
The S260S produces minimal odour because separating liquids from solids prevents ammonia smell formation. Solid waste dries out and produces little odour when kept separate. The side-operated blade keeps waste out of sight and contains smells. For additional odour control, the toilet works with the optional Thetford ventilation kit A0032630, which actively ventilates odours away. No chemical additives are needed, so there are no chemical odours either.
Where do you empty the waste from a Thetford separation toilet?
The urine tank from the S260S empties into any standard toilet, grey water outlet, or down a drain. The solid waste bucket uses biodegradable bags and disposes like household waste in appropriate bins. This gives you more flexibility than cassette toilets, which require specialist chemical waste disposal points at campsites or service stations. The leak-free connection design prevents spills when disconnecting the urine tank for emptying.
Can you convert an existing Thetford cassette toilet to a separation toilet?
Yes, Thetford offers a separation toilet conversion kit for existing C220 and C260 cassette toilets. The conversion kit lets you switch from a water-flush cassette system to a waterless separation system without replacing the entire toilet unit. The S260S is also available as a complete toilet for new installations, modelled on the C260 cassette toilet footprint for straightforward fitting in existing spaces.
What are the dimensions and weight of the Thetford S260S separation toilet?
The Thetford S260S measures 488mm wide, 340mm deep and 603mm high. The seat height is 467mm from the floor, providing standard toilet height for comfortable use. The complete unit weighs 7.1kg, making it relatively lightweight for installation. The solid waste bucket holds 7 litres and the urine tank holds 7.5 litres. It requires a 4-pole electrical connection for the electronic level indicator.
