6 Best Cassette Toilets for Vanlife

Did you know using a cassette toilet can eliminate the need for a larger black water tank or any RV plumbing? Read on to learn why cassette toilets are a good option for vanlife.

It’s an age-old debate… Is a luxury such as a cassette toilet really worth the money and space it takes up in your van? There’s always plenty of outdoor space or public toilets to get the job done, right?

However, imagine this. You’re camping in freezing temperatures and the thought of opening up that sliding door to go to the bathroom outside seems unbearable. Or maybe you’re stealth camping in the city and there’s no toilet in the vicinity.  What’s your plan?

Personally, having a toilet in my van is a must. In my first van, I chose to install a fully plumbed RV toilet. But in my second van, I’ve opted for the popular cassette toilet.

A cassette toilet is a bit different from other options of portable toilets

With a cassette toilet, a toilet is installed over a small, removable waste tank. Once you’re done using it, the waste moves into the portable waste tank, instead of going into a black holding tank. Once the waste tank is full, you take it out through an exterior service door and empty it into a standard toilet or authorized dumping station. You can then put the small waste tank back into your van.

Unlike other plumbed toilets, a cassette toilet eliminates the need for a larger black water holding tank or any RV plumbing. It is also much more convenient to install and use than a regular composting toilet.

Cassette Toilets Buyer’s Guide

Buying the best campervan cassette toilet is an investment that needs to be done with a lot of research. Checking product warranties, additional features, and price comparisons are essential to your buying decision. 

Here are a few things to keep in mind before you dive into shopping for a cassette toilet to meet the needs of your campervan.

What to Look for in a Cassette Toilet

The top three things you need to look for in a Cassette toilet are:

1. Holding Tank Capacity

An essential part of making your buying decision is looking at the holding capacity of a cassette toilet. If you’re travelling with multiple people, you’ll want to consider a larger tank so that you don’t have to empty it as frequently.  However, keep in mind that a large full tank can become heavy and difficult to dump.

2. Transportability

Added wheels and carrying handles are a plus for transporting waste from the waste tank and dumping it. These features should be a make or break for your buying decision.

3. Leakage

Look for toilets with lid-locking seats or sealed valves to prevent potential dripping.

Added Features

Waste Level Indicator

A waste level indicator is a nice feature to consider in your cassette toilet. It displays how full your waste tank is, so you don’t have to go through the pain of manually checking it.

Emptying Spout

An emptying spout makes cleaning easier. This feature is a must-have if you don’t want to come in contact with waste while cleaning your cassette toilet.

Using and Maintaining a Cassette Toilet

Using a cassette toilet is quite similar to using a regular toilet. It contains a regular seat and a bowl, so you can comfortably sit, release, and flush once you’re done.

However, as simple as it sounds, there can be limitations to using a cassette toilet. 

Here are some tips you can follow for optimum usage:

  • Dump the wastewater tank frequently. A full tank can become heavy and difficult to dump.
  • Clean the toilet regularly to prevent odors. 
  • Toilet cleaning chemicals tend to work best for cleaning cassette toilets. They break down contents and control odors. However, they contain toxic substances, and gloves must be used while handling them.


Can you poop in a cassette toilet?

This is a personal decision but you definitely CAN. A cassette toilet functions quite similarly to a traditional RV toilet, which means it can easily hold liquid as well as solid waste.

How often do you need to empty a cassette toilet?

This depends on the holding capacity of your cassette toilet and how many people you’re traveling with. Many choose to wait until the indicator level in the cassette toilet shows full. However, it is recommended that you empty the waste tank every 1-2 days in an authorized dumping station. A full tank will make the process of emptying the cassette pretty difficult.

Can you put toilet paper in a cassette toilet?

A specific RV toilet paper must be used in a cassette toilet. Regular toilet paper can lead to blockages or even clogged tanks. An RV-toilet paper is thin and fast dissolving and eco-friendly. 

It’s recommended to use the Thetford Aqua-Soft Toilet Tissue, which is 2-ply, highly absorbent, and specifically designed for RVs.

Key Takeaways

While buying a cassette toilet sounds like a no-nonsense decision, many things need to be considered before you make your purchase. 

Our top picks for cassette toilets include the:

  1. Dometic Portable Cassette Toilet
  2. SereneLife Outdoor Portable Toilet and 
  3. Porta Potti White Thetford Corp

So make sure you consider these, along with others mentioned above.
