DIY composting toilet – build your own sustainable toilet

Are you looking for a sustainable, durable and cost-effective composting toilet?
With the DIY kit from ecoshit, you can build your own fully functional composting toilet in just a few steps – individual, robust, and environmentally friendly.

All you need is some additional material for the enclosure—for example, leftover wood, roof battens, a metal box, or even an old ammunition crate. There are no limits to your creativity.

Simply build it yourself – with a system

The DIY kit contains all the key components you need for a fully functional composting toilet:

✅ Separator – the heart of the toilet

✅ Bucket for solids

✅ Urine canister (optionally 5 l or 10 l)

✅ Canister lid with integrated odor trap

✅ Detailed assembly instructions (PDF & video) with material and tool list

The instructions guide you step by step through the construction of a sturdy wooden cabinet. You can customize the structure to your liking—with a toilet seat, toilet paper holder, or litter tray.
This is how you create your very own, self-sufficient feel-good toilet.
