The Thetford SK220 Separation Toilet Kit transforms your existing C220 cassette toilet into a modern separation toilet without the need for a complete replacement. This conversion kit offers caravan and motorhome owners an eco-friendly alternative to traditional cassette toilets by separating urine and solid waste at source. The SK220 works completely without water, eliminating the need for chemical additives whilst providing longer intervals between emptying and greater freedom when choosing where to stop.
How does the Thetford SK220 improve off-grid camping?
The SK220 separation kit extends your self-sufficiency by separating waste into a 7.5L urine tank and 7L solid waste bucket, both made from recycled plastic. The urine tank features a mechanical level indicator and leak-free connection for easy emptying into any standard toilet, whilst solid waste dries naturally to reduce odours. At 3.5kg, the complete kit installs directly onto your C220 base with an ergonomically optimised bowl and blade cover for visual privacy.
Installation is straightforward with all components included in the complete bowl assembly, making the switch from cassette to separation toilet achievable in your own time. The leak-free automatic closing connection to the urine tank prevents spills during removal and disposal. Both tanks are constructed from recycled plastic, supporting environmental sustainability whilst maintaining durability for regular use. Optional ventilation (part A0032629) enhances the odour-free experience, though the separation design itself prevents ammonia formation by keeping liquids and solids apart from the outset.
This separation system offers distinct advantages over traditional cassette toilets for off-grid travellers. You'll spend less time searching for disposal points since the urine tank empties into any conventional toilet and solid waste goes in general waste. There's no ongoing cost for sanitary chemicals, and the separation prevents the characteristic cassette toilet mixture odour. The mechanical level indicator on the urine tank lets you monitor capacity without guesswork, whilst the blade cover maintains discretion and helps contain any residual smells.

Frequently Asked Questions
Which Thetford toilets does the SK220 separation kit fit?
The SK220 separation kit is designed specifically to convert any Thetford C220 cassette toilet into a separation toilet. It replaces the existing bowl and tank assembly of C220 models with a complete separation system including bowl, urine tank, and solid waste bucket. The kit does not fit other Thetford cassette toilet models such as C200, C260 or C400 series.
How do you empty the Thetford SK220 separation toilet?
The SK220 features two separate waste containers for disposal. The 7.5L urine tank has a leak-free automatic closing connection and empties into any standard toilet, bathroom drain, or suitable outdoor location. The 7L solid waste bucket uses biodegradable bags and disposes of in general waste bins. The mechanical level indicator on the urine tank shows when emptying is needed, typically extending intervals compared to traditional cassette toilets because waste separation prevents tank capacity being consumed by mixed liquids.
Does the Thetford SK220 need chemicals or water?
The SK220 separation toilet operates completely without water or chemical additives. The separation design keeps urine and solid waste apart from the moment of deposit, which prevents ammonia formation and the need for odour-masking chemicals. Solid waste naturally dries in its separate bucket, minimising odour without additives. This waterless operation eliminates ongoing chemical costs and reduces environmental impact compared to traditional cassette toilets that require regular sanitary fluid purchases.
Is ventilation required for the SK220 separation toilet?
Ventilation is optional but recommended for the SK220 to optimise the user experience. The separation design itself significantly reduces odours by keeping liquids and solids apart, preventing ammonia formation. Thetford offers a compatible ventilation kit (part number A0032629) that provides active air circulation to further minimise any residual odours from the solid waste compartment. Many users find the separation system adequate without ventilation, though installation improves comfort during extended off-grid periods.
What are the capacity and weight specifications of the SK220?
The SK220 separation kit weighs 3.5kg and includes a 7.5L urine tank with mechanical level indication and a 7L solid waste bucket. Both containers are manufactured from recycled plastic. The separation design typically allows longer intervals between emptying compared to equivalent cassette toilet capacities because waste remains unmixed. The urine tank's 7.5L capacity suits most couples for multiple days of use, whilst the solid waste bucket capacity depends on usage patterns and biodegradable bag management.
