It is suitable for DIY projects, upgrades of existing systems and as a spare part – designed for everyday, comfortable use without any need for adjustment.
Comfortable separation in everyday life
The separator insert allows for reliable separation of urine and solids while maintaining a seated position similar to a conventional toilet. Its ergonomic design ensures intuitive use and clean handling in everyday life.
The geometry is designed so that it is easy, safe and reliable for women to use – without any need for adjustment or special sitting posture.
In combination with ventilation and urine tank, odors are effectively avoided – everything stays where it belongs.

Suitable connectors are available separately and allow for flexible adaptation to installation space and system requirements.
This means the divider adapts to your project – not the other way around.
