The Thetford Separation Toilet S220s represents a shift in how off-grid campers and motorhome owners approach waste management. This waterless toilet separates urine and solid waste at source, removing the dependency on chemical additives and fixed disposal points. Built with recycled plastic construction and featuring a 7-litre solid waste bucket paired with a 7.5-litre urine tank, it's designed for extended self-sufficiency without the bulk of traditional cassette systems. At 492mm seat height and weighing 6.8kg, it fits standard C220 mounting configurations.
How does a separation toilet work without water or chemicals?
The S220s uses a diverted bowl design that directs urine into a separate 7.5-litre tank whilst solid waste drops into a 7-litre bucket. The patented blade provides visual coverage whilst separation prevents ammonia formation, keeping odours minimal without chemical additives. Solid waste naturally dries, and the urine tank features mechanical level indication for straightforward monitoring.
Off-grid touring demands flexibility, and this toilet delivers on practicality. The ergonomically optimised bowl connects to both tanks through leak-free channels designed for reliable operation. You'll empty the urine tank in any standard toilet and dispose of solid waste hygienically using compostable bags. The mechanical level indicator on the urine tank removes guesswork, whilst optional ventilation (kit A0032629) adds active extraction for extended trips. Installation mirrors the C220 cassette toilet footprint at 498 x 394 x 580mm, with Door 3 access available as an optional fitting.
The waterless operation means no fresh water consumption and zero ongoing costs for sanitary fluids. Separation toilets extend emptying intervals compared to cassette systems because waste doesn't mix into a heavy liquid mass. You're free to camp where facilities are sparse or non-existent, and disposal becomes straightforward rather than dependent on specialised dump stations. This is practical sanitation for modern tourers who value independence without compromising on hygiene.

Frequently Asked Questions
How often do you need to empty the Thetford S220s separation toilet?
Emptying frequency depends on usage, but the 7.5-litre urine tank typically requires emptying every 2-4 days for two people, whilst the 7-litre solid waste bucket lasts considerably longer, often 1-2 weeks. The mechanical level indicator on the urine tank alerts you when capacity is reached. Because waste remains separated and solids naturally dry, you'll find emptying intervals are longer than traditional cassette toilets where everything mixes into a heavy liquid mass.
What's the difference between the S220s and a cassette toilet?
The S220s operates without water or chemicals and separates waste at source into two containers, whilst cassette toilets flush waste into a single holding tank using water and chemical additives. Separation toilets eliminate ongoing chemical costs, require no fresh water for flushing, and allow flexible disposal since urine empties into any standard toilet and solids dispose hygienically in compostable bags. This means you're not dependent on specialised dump stations.
Will the Thetford S220s fit my existing C220 toilet space?
Yes, the S220s is designed to fit the same mounting configuration as Thetford C220 cassette toilets. It measures 498 x 394 x 580mm with a seat height of 492mm, matching standard C220 dimensions. The toilet uses Door 3 access (available as an option) and the complete bowl installation makes fitting straightforward. If you're replacing a C220, the S220s drops into the existing space without requiring modifications to your bathroom layout.
Does the separation toilet smell without chemicals?
The separation design prevents ammonia formation because urine and solid waste don't mix. Solid waste naturally dries in the separate bucket, reducing odours significantly. The patented blade provides visual coverage when not in use. For additional odour control, you fit the optional ventilation kit (A0032629) which actively extracts air from the toilet bowl and vents it outside. Most users find separation toilets produce less odour than cassette systems with chemical additives.
Where do you empty the waste from a separation toilet?
The urine tank empties into any standard toilet, public facilities, or grey waste disposal point. The solid waste bucket uses compostable bags that dispose of in general waste bins or composting facilities where permitted. This flexibility means you're not restricted to dedicated chemical waste disposal stations required by cassette toilets. The leak-free connection on the urine tank makes emptying straightforward without mess, and the solid waste container handles hygienically with the bag system.
