Campervan Conversion Crafter Motorhome Toilet Bathroom

Although not an enjoyable subject to discuss, the toilet is a very important part of any conversion. Giving some thought to how you’re going to dispose of the waste when on trips is important. Many people don’t realise there are a few different options available. We’ve included all options that would work in a larger campervan conversion like a Crafter or MAN

Finding the right toilet involves some compromise since there's no one-size-fits-all solution, but certain options might be a better fit for different people.

Cassette Toilet

A Cassette Toilet, like Thetford or similar, is a compact sanitation solution designed for motorhomes and campervans. This toilet system consists of two main components: a toilet bowl and a removable waste-holding tank, known as the cassette.

The toilet operates by using a small amount of water to flush waste into the cassette, which can be easily detached and emptied at designated disposal sites. Cassette toilets are the most common toilet type in motorhome conversions. You add green or blue chemical to the system to stop smells. 


  • Easy Maintenance: Simple to empty and clean
  • Water Independence: No need for lots of water
  • Size: Can fit into small wetrooms or bathrooms
  • Tiny amount of electricity required for the tank level indicator


  • Limited Capacity: Requires frequent emptying
  • You can only empty the tank at certain disposal points
  • Can be a smelly job to empty the tank
  • Can be heavy to carry when full
  • Not for Full-Time Use: Best suited for occasional use
  • Maintenance: Regular care for the cassette tank is essential
  • Uses chemicals to stop the smell - bad for the environment

Composting Toilet 

Composting toilets are eco-friendly alternatives that work by converting human waste into compost. These toilets utilise a natural decomposition process to break down organic matter.

Over time, the waste transforms into nutrient-rich compost that can be safely and hygienically disposed of or used as fertiliser. Composting toilets are waterless and do not require a connection to traditional sewage systems, making them a sustainable and off-grid-friendly option.

Modern composting toilets, like Separate or Simploo, are becoming more popular. These work by separating the liquid and solid waste. By separating the waste it prevents “sewage” which means there is little to no smell. In your campervan you would have a small 12v fan fitted which draws out any smells to the outside.

Vacuum Toilet

There are a few Vacuum toilets on the market. We will be focusing on the C1 toilet from Clesana. It is distinctive because it operates without water. After using the toilet, a fan creates increased air pressure, causing the waste to compress into a bag. This compressed waste is then sealed at the top, separated, and drops into a drawer. The Clesana C1 toilet operates on 12 volts.
