The retrofit
Same shell. New unit.
BASE installs into the portable toilet you already own. The shell, the tank and the service route stay the same.
Before

After

Install
Three installs. One crew.
01
Roof module
A compact exhaust fan and carbon filter module fits into a cut opening in the existing roof and fastens with stainless hardware.

02
Pedal flush
A stainless foot pedal and linkage bolt to the existing floor beside the seat. It works by foot, with no power needed.

03
Service module
A keyed panel holding the battery and sanitizer cartridge mounts to the existing wall, so a crew can swap parts on route.

Note
These are concept renders that show the intended installation. Final parts, fit and install times are confirmed in the pilot program, unit by unit.
