Thetford S220CS Separation Toilet

The S220CS is Thetford's separation toilet, built as a direct-fit alternative to a C220 or C260 cassette toilet in the same footprint. Rather than flushing waste into a shared cassette, it separates liquid and solid waste at the bowl: urine drains via a leak-free, automatically closing connection into a 7.5-litre tank with its own level indicator, while solids drop into a separate composting-style container behind a visual waste-covering blade that keeps odour and mess out of sight between uses. The tanks are moulded from recycled plastic, and the ergonomically shaped bowl is designed for comfortable use in the same space as a standard cassette toilet. It suits owners looking to move away from chemical-based cassette toilets toward a lower-water, lower-chemical separation system, and pairs with Thetford's optional electric ventilation kit, charcoal filter and compostable waste bags.

• Q: Can this replace my existing C220 or C260 cassette toilet directly?
  A: Yes, the S220CS is designed and marketed as a direct-fit alternative to the C220/C260 in the same installation space, though you should check your existing cut-out and plumbing/venting before ordering.
• Q: Does it need a power connection for ventilation?
  A: A passive charcoal filter is included/available, but Thetford also offers an optional electric ventilator kit for improved airflow and drying of the solids container, it's not compulsory but is recommended for full-time use.
• Q: Do I still need to use toilet chemicals with it?
  A: No, as a separation toilet it doesn't rely on chemical-based liquid holding like a cassette toilet; solids are managed with a compostable liner/bag and the urine tank is simply emptied and rinsed.
• Q: How often does the urine tank need emptying?
  A: That depends on usage, but the 7.5-litre tank has a built-in level indicator so you can check and empty it as needed rather than working to a fixed schedule.
