Waterless composting toilets in Australia are an easy to maintain, and a modern way to flush your toilet while saving water.
Waterless composting toilets are designed to provide rich and odourless nutrients to use in a garden. Since over 30,000 litres of water is wasted through average toilets in Australia every year, using a composting toilet is a great way to avoid wasting water (low flow shower heads are another great way).

Most Important Factors to Look for in Your Composting Toilet
When choosing an excellent composting toilet, it is essential to know what kind of toilet will best fit your location and what the tank capacity is.
You should know whether you need a self-contained composting toilet or a split system. Both composting toilets work great, but they have different requirements and work differently.
Choosing a Composting System
It can be challenging to choose a composting toilet if you are unsure which kind you need. Split systems are split into two sections called the pedestal and the tank. The pedestal is above the floor, and the tank is below the floor.
Split systems are a good fit for national parks, outhouses, homes, sports clubs, and clubhouses because they have a larger capacity and can be installed in an area where multiple people need to use the loo.
A self-contained composting toilet is an all-in-one system where the pedestal and container are all built into one system. Self-contained systems best fit tiny homes, RVs, caravans, motorhomes, boats, and single-level homes built on concrete. Self-contained systems are suitable for those who are limited in space, including those who live off the grid.
How Much Space Do You Have?
Before selecting a composting toilet, you will need to know how much space you have. Before purchasing a toilet, you must see if you have space under the floor. If you use a self-contained composting toilet system, you will not need to worry about space under your floor.
If you go with a split system, you will only need to worry about under the floor space. Since split systems need the pedestal above the floor and the tank below the floor, you must ensure you have enough underfloor space before choosing a split system.
Self-contained systems are best for small spaces, like tiny homes or motorhomes, because they sit on top of your floor and do not take up much space.
Tank Capacity
Your composting toilet’s tank capacity is necessary to remember before choosing which toilet to go with.
The tank capacity of your toilet depends on which toilet you select and whether or not it is a split or self-contained system. Most composting toilets will specify how many users it can handle and how often it should be emptied.
It also depends on how many people will be using the toilet. Typically, a family of two can go about three weeks without emptying the tank. However, a family of four should empty it more frequently.
A split system used more than 10 times will need to be emptied every couple of months. To be sure you are emptying the toilet when necessary, check the manual for your toilet, as it states the capacity and how much it can hold.
Utility Usage
Some composting toilets run on RV batteries, some are powered by solar panels, and some need water lines. Composting toilets has many pros, like using minimal to no water, and they lower your environmental impact. However, some composting toilets can be hooked up to run on your RV’s battery, which is not as sustainable in the long run.
Some composting toilets will need to be hooked up to water lines for minimal water use, which can also be unsustainable if you live off the grid. Most composting toilets can run on solar power, best suited for you and the environment.
Many off-the-grid Australians often use rainwater harvesting as an additional way to lower their utility usage. Rainwater harvesting and composting toilets will significantly reduce your utility usage.
Solar-powered composting toilets are the best fit for waste-conscious homesteaders and those trying to eliminate utility usage.
Odour Removal
Most composting toilets are designed not to produce odours, but that doesn’t mean they won’t occasionally smell bad. If you maintain your composting toilet correctly, it should not smell. If you notice a smell, you can do a few things to get rid of the stench. Be sure your compost pile has the right amount of moisture.
It should be moist rather than wet. You can also keep the toilet’s lid down to prevent smells from entering, so bugs do not make their way into the toilet. When you empty the compost pile, use a natural cleaner to clean the toilet properly.
Another reason your composting toilet might smell could be due to improperly installed venting. If installed incorrectly, the fan might blow the smelly air back into your home rather than outside.
FAQs
Is there a composting toilet that you don’t have to empty?
No, all composting toilets need to be emptied eventually. A self-contained system consists of a small toilet with a detachable tank and liquid drain to remove human waste.
A split system connects to a series of pipes where the composting occurs. The hopper churns the waste and fills the tank with rubbish that still needs emptying.
What are the disadvantages of a composting toilet?
Composting toilets do not always save space, they might be challenging to use, they require more maintenance than standard toilets, some do not contain odour as well as others, and you might need a special permit to install them.
Are composting toilets high maintenance?
If your composting toilet is installed correctly and maintained, it should not be high maintenance. Composting toilets only become high maintenance when they are let go for too long and not properly maintained.
It does require more maintenance than an average toilet, but only because you need to empty the compost every so often.
Bottom Line
These eight toilets are the best picks for composting toilets in Australia. Even though composting toilets require more maintenance than the average toilet, the extra effort is worth it.
