Toilets & Sanitation

Caravan Toilets & Sanitation

Shop caravan and RV toilet chemicals, sanitation products and common toilet parts to keep everything working cleanly on the road. From cassette toilet treatments to maintenance items and replacement parts, the right products help reduce odours, improve waste breakdown, and protect seals and moving components.

Before ordering, check what toilet system you have (cassette or fixed holding tank) and choose treatments designed for that setup. Using the correct chemical and the correct dose helps performance and reduces build-up over time. If you’re replacing parts, identify the toilet brand/model and compare measurements so seals and fittings match properly.

For best results, keep seals clean, use the recommended treatment, and empty/flush regularly—especially in warmer weather. If you’re unsure what you need, start with your toilet type and the problem you’re trying to fix (odour, slow breakdown, seal leaks, or general maintenance).

What toilet chemicals do I need for a caravan cassette toilet?
Most cassette toilets use a waste tank treatment to help break down waste and control odours. Some people also use a rinse tank additive (if your toilet has a separate rinse tank). Choose products designed for cassette toilets and follow the dosing instructions.
It’s usually best to avoid harsh household chemicals and bleach in cassette systems because they can damage seals and plastics and may not be suitable for dump points or septic systems. Use caravan-specific treatments and cleaners where possible.
Empty as needed, but don’t let it sit too long—especially in hot weather. A regular rinse and clean helps prevent odour and build-up. If you notice smells or slow breakdown, it’s a good time for a deeper clean and seal check.
Common causes include incorrect dosing, not enough water in the cassette, seal wear, or build-up inside the tank. Try using the correct dose, add adequate water, and inspect seals. A cassette deep clean can also help.
Leaks around the cassette, difficulty operating the blade/slider, or persistent smells can indicate worn seals. Matching the correct seal to your toilet brand/model is important for a proper fit.
Many caravan toilet treatments are designed to be compatible with septic systems and dump points, but always check the product label. If you’re staying somewhere with strict requirements, choose septic-safe treatments.
Confirm the toilet brand/model (or compare the old part), and check measurements and connection style. For parts like seals, valves and caps, small differences can matter.
