Cassette Toilet vs Composting Toilet: Which Is Better?

OGO Composting Toiler allows for additional storage as it does not require access from the outside

When it comes to choosing the right toilet setup for your offroad caravan, the two main contenders are the cassette toilet and the composting toilet. Both have their pros and cons — and the better choice really depends on how and where you plan to travel.

Let’s break it down.

What Is a Cassette Toilet?

A cassette toilet is the standard in most caravans. It has a fixed bowl and a small waste holding tank (the “cassette”) that you can slide out and empty into a dump point.

✅ Pros:

• Simple to use – feels like a normal toilet.

• Easy to clean and maintain.

• Widely accepted at caravan parks and dump points.

• Compact and integrates well into most van layouts.

❌ Cons:

• Needs frequent emptying – especially for couples or families (every 1–2 days).

• Requires chemicals to control odour and break down waste.

• Dump points only – you need to find an appropriate place to empty it (not always easy in remote areas).

• Not great for extended off-grid stays unless you carry a spare cassette.

  
  

What Is a Composting Toilet?

A composting toilet separates liquids from solids. Solids are collected in a compost bin (often with coconut coir or peat moss), while liquids go into a separate bottle. No water, no chemicals.

✅ Pros:

• No chemicals needed – more eco-friendly.

• Can go weeks without emptying the solids (depending on use).

• Perfect for off-grid camping – you don’t need to rely on dump points.

• Often odour-free when used correctly.

❌ Cons:

• Bigger upfront cost (can be 2–3x more than a cassette).

• More space required – physically larger unit.

• More involved setup/learning curve.

• You still have to dispose of liquids more often (usually every 2–3 days).

• Some people are put off by the idea of dealing with composted solids, even though it’s much less gross than it sounds.
  

Which Toilet Suits Offroad Travel?

If you’re mostly staying in caravan parks or travelling short distances, the cassette toilet is convenient and familiar. It’s the “plug-and-play” option.

But if you’re planning remote, long-term, or fully off-grid travel, a composting toilet is hard to beat. Less emptying, no need for chemicals or dump points, and fewer restrictions.

Our Take at Offroad Grit

We fit cassette toilets as standard in most models, but we offer composting toilet upgrades for those who want true off-grid flexibility.

If you’re unsure, ask yourself:

• Do you like to free camp for a week or more at a time?

• Do you prefer to avoid caravan parks?

• Are dump points sometimes hard to find where you go?

If yes, a composting toilet might be worth the upgrade.

Final Thoughts

Both systems will do the job — it just comes down to how you like to travel.

Cassette = Easy and familiar.

Composting = Long-term, eco-friendly independence.
