Tanks & Accessories

Having a fresh and new waste tank is truly recommended over the years, the seals can dry out and bacteria can accumulate if it has not been properly maintained. We have replacement tanks for the most common models from Thetford and Dometic. Models such as C200, C220, C250/260, C400, C500, C2/C3/C4 & Dometic waste tank. Are you unsure which one you have? There is a label on your current tank and also on your toilet where you can see which model you need to replace. If your toilet is called Thetford 263 CS, then the cassette C250/C260 is what you should have. If you have an older tank with no label, you can take a picture of the tank and email it to us, and we will of course help you. Scroll down and see below!
