Self-Contained Systems (On Floor) are toilets where the composting or treatment unit is fully contained within the cabinet that sits on the floor, similar to a large appliance. They are ideal for retrofits and situations where there is no under-floor space or access for a remote chamber.
Typical uses include homes, baches, tiny cabins, sleepouts and studios where a waterless or ultra low-flush solution is required with minimal building work.
