The goal of the project was to add a toilet to the Prachov Rocks that looks like it has always been there. It should also fit nicely into the forest. A plastic TOI TOI could never do that.

The composting toilet is made of larch and spruce wood. We even made our own CLT panels for the ceiling and floor. The composting system was supplied by the company Ekozáchody.cz. This type of toilet is eco-friendly and cheap to run. It doesn’t need any chemicals, water, or electricity. It doesn’t smell, doesn’t attract annoying insects, and even creates high-quality fertilizer for your garden.
