A composting restroom building prefabricated to meet your needs. Bio-Sun Systems offers concrete buildings and conventional steel studded frame built restroom buildings with our patented "Excel-Aerator" compost toilet system. Your building and composter come delivered and set-up at your site with no water or sewer hookup.

A near zero maintenance, zero discharge facility that can handle up to 500 uses per day!

Solar/wind power can be included for areas without commercial power.

Choose between three exterior finishes: broom, exposed aggregate or simulated brick for the concrete buildings.

The conventional (Sunflower) buildings come standard with rot proof, fire resistant, termite proof cementitous siding and concrete floor. Custom sidings and facades also available.
