Composting Toilets: The 5 Best Available in NZ – 2026
One question we get asked all the time by prospective Tiny Home clients is ‘what happens with the plumbing’. The answer is, there are many options. Some clients go connect to a preexisting septic system with full 100mm buried pipes, or they may connect to the septic with a macerator pump. One of the most common solutions is utilising a Composting Toilet.
At Fox Cabins, since 2017 we have built over 100 Tiny Homes, and have installed most of the available composting toilet brands in that time.
This list will hopefully help you with your selection of the best composting toilet available for your Tiny Home today.
Why choose a Composting Toilet?
Better for the Environment
- No Blackwater permeating the aquifer.
- Does not use clean drinking water to flush away waste.
- Reduces Carbon Footprint by eliminating using treated, purified water to flush away waste.
Zero Water Use
- Can save over 35,000 litres of water per year per family, or around 40% of a household’s water use.
- Ideal for Off Grid, Tiny Home and Motorhome applications where water collection, storage and disposal are difficult.
- Great for rural settings with households that are on tank water and are looking to reduce water usage where running out of water means trucking it in.
Low Cost
- Septic Tank systems can cost around $15,000 to $25,000 to install.
- Waterless Composting Toilets are a fraction of that cost, at around $2,000 for quality models with plenty of functionality.
- Low to zero running costs (just the cost of composting medium such as sawdust or coconut coir).
Self Contained
- No underground water pipes in, no waste pipes out means you can move your Tiny Home/Motorhome easily. Park anywhere, move anywhere.
No Odour
- Venting systems dry solids speeding the composting process.
