What Is a Cassette Toilet?

A cassette toilet is a compact toilet with a removable waste tank. Instead of a large black tank, waste drops into a sealed cassette that you carry to a dump point. This flexibility makes cassette toilets popular in small rigs and in any RV with cassette toilet features. Many travelers choose these setups because they are reliable and very easy to manage.

How Do Cassette Toilets Work?

To understand how does a cassette toilet work in a caravan, it helps to look at the key parts involved.

How It Works: Overview

When you flush, waste moves from the bowl into a sealed cassette tank below. The tank locks into place and can be removed from an exterior access door.

Flush Mechanism

The flush uses either:

  • A manual pump

  • An electric button

This sends clean water into the bowl.

Waste Cassette

The sealed waste tank holds liquids and solids. It includes a handle and wheels in some models.

Valve

A blade valve separates the toilet bowl from the waste tank. You open it before use and close it after flushing.

Indicator Light

Most units include a light that turns on when the cassette is almost full.

These parts create a simple system. This ease of use supports our goal to bring comfort and smart design to every journey.

How to Use a Cassette Toilet

Before Use

Fill the cassette with the right chemicals and a small amount of water.
