Thetford Seperation Kit – SK 220

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.
