Composting toilet vs cassette toilet: which is right for you?

When you’re on the road, out on the water, or just off-grid, having a reliable toilet system is crucial. The of two most common options for those seeking portable, eco-friendly toilet solutions are composting toilets and cassette toilets. Each type has its advantages and disadvantages, so how do you decide which is right for your situation?

In this article, we’ll compare composting toilets and cassette toilets, focusing on their features, pros and cons, and which one might be the better fit for your needs. Yes, we do have a favourite!

What is a Separating Composting Toilet?

A composting toilet is an eco-friendly system that uses a natural decomposition process to break down human waste. Instead of flushing waste away with water, composting toilets rely on aerobic bacteria to turn waste into compost. By separating liquids from solids, the composting process can take place efficiently, minimizing odors and reducing the volume of waste over time.

Air Head Composting Toilets, for example, stand out in the market due to their design and comfort, along with their specially designed rubber gaskets on the lid, seat, and bowl, which ensure a tight seal to prevent leaks and odors. The solid and liquid separation system further reduces odors while making the unit easy to maintain.

Benefits of Composting Toilets

  1. Eco-Friendly: Composting toilets are a sustainable option. They don’t require water, meaning they’re perfect for dry environments and reducing water consumption and storage. Additionally, the composted material can be used as a non-food based fertilizer, making it a true “zero-waste” solution.
  2. Odor Control: Thanks to the separation of liquids and solids, along with the included fan and vent which enables the composting process itself, composting toilets are surprisingly low-odor, and the odor which is there is a mild earthy smell. Which is a significant advantage when you’re in a confined space like an RV or boat.
  3. Cost-Effective: Since composting toilets don’t rely on water or chemicals, they can save you money in the long run. You won’t need to keep buying chemicals to neutralize waste, and you won’t waste water with every flush.
  4. Minimal Maintenance: While you do need to empty the solids container occasionally (every few weeks, depending on usage), composting toilets are generally very low maintenance. For example, Air Head’s composting toilets can be emptied without disassembling the unit, which adds to the convenience factor.
  5. Versatile Installation: Composting toilets can be installed in a variety of environments, including tiny homes, RVs, boats, and off-grid cabins. Air Head Composting Toilets, for instance, can be installed even in wet head/shower areas because of their water-resistant design, preventing water from entering the composting area.

Drawbacks of Composting Toilets

  1. Space Requirements: Composting toilets are typically larger than cassette toilets, as they require space for both the liquid and solid containers, as well as the composting material. In smaller RVs or boats, finding the right spot can be challenging.
  2. Power Consumption: Most composting toilets require a small fan to help with airflow, which uses some electricity. Although it’s usually a minor amount, it’s something to consider if you’re off-grid with limited power options.
  3. Initial Cost: Composting Toilets like Air Head are premium products with top of the line quality and materials, and as such they have a higher price point compared to a Cassette toilet.

What is a Cassette Toilet?

A cassette toilet is a more traditional portable toilet system, typically found in RVs. Unlike a composting toilet, a cassette toilet uses water to flush waste into a small, removable waste tank (the cassette). These tanks are designed to be emptied manually at designated dump stations or other approved areas.

Cassette toilets are often installed in compact spaces and are known for their portability and ease of use. They operate much like a household toilet but on a smaller scale.

Benefits of Cassette Toilets

  1. Compact Design: Cassette toilets are typically smaller than composting toilets, making them a good fit for RVs, boats, and other small spaces where every inch counts.
  2. Ease of Use: Since cassette toilets mimic traditional toilets, there’s not much of a learning curve. Users simply flush like they would at home, making it a familiar and comfortable option.
  3. Less Maintenance: There’s no need to worry about composting or separating liquids from solids. You just need to empty the waste tank when it’s full, which is usually every few days, depending on usage.
  4. No Electricity Required: Cassette toilets don’t need any power to function, making them an ideal choice for those without a steady power supply.

Drawbacks of Cassette Toilets

  1. Odor Issues: While many cassette toilets use chemicals to help break down waste and control odors, these chemicals can be harmful to the environment. Moreover, emptying the waste tank can be unpleasant, as odors are more noticeable at that time.
  2. Frequent Emptying: The waste tank of a cassette toilet is relatively small, meaning you’ll need to empty it often—every 2-4 days depending on use. This can be inconvenient, especially if you’re in a remote location without easy access to a dump station.
  3. Limited Waste Capacity: Because of their compact size, cassette toilets are only suitable for small amounts of waste, which may not be practical for larger families or extended off-grid stays.
  4. Chemical Use: Cassette toilets require chemicals to break down waste and reduce odor. These chemicals need to be purchased regularly, adding an ongoing cost. Additionally, they’re not as environmentally friendly as composting toilets.
