Choosing the right Thetford cassette toilet doesn’t have to be confusing — but with several models on the market, it can feel overwhelming if you’re new to motorhome or caravan life.
In this article we’ll break it all down in simple terms — what each model does, which one fits your setup, and how to make the right choice for comfort, convenience, and reliability on the road.
What Is a Cassette Toilet?
A cassette toilet is a built-in Campervan or Motorhome toilet with a removable waste tank (called the cassette) that you empty at designated waste disposal points. Unlike portable toilets, cassette toilets are permanent, more comfortable, and designed specifically for caravans, motorhomes, and campervans.
Thetford are one of the most trusted brands in Europe — known for durability and wide parts availability.

How to Choose the Right Model — Quick Checklist
Are you replacing an existing cassette toilet?
Stick with the same model family where possible to avoid cut-outs and trim work.
Do you have onboard water?
Yes → C220 or C260
No → Choose C200 variant with onboard flush tank
How often will you empty the cassette?
If it’s weekly or more often, the C260’s wheeled cassette is worth it.
Comfort vs Space?
Premium vs compact toilets are often a trade-off — pick based on your bathroom layout.
