Manufacturer of eco-friendly public dry toilets since 1991
Sanitation solutions tailored for every environment
Sanisphere designs eco-friendly facilities adapted to every public location, from rural villages to motorway rest areas.
Rural Communities
Autonomous, reliable, and easy-to-maintain dry toilets for small municipalities.
Urban Communities
Durable, attractive installations for urban parks and public spaces.
Protected Areas
Eco-friendly sanitation facilities designed to blend discreetly into sensitive natural environments.
Recreational Areas
Comfortable, robust solutions for lakes and bodies of water, leisure parks, and tourist sites.
Service areas and motorways
Dry toilets designed for high footfall and optimised maintenance.
A complete range of public dry toilets
Installations designed to meet every type of environment: urban, rural, or natural.
A patented technology, waterless, designed for impeccable hygiene
Sanisphere designs and manufactures autonomous dry toilets with natural ventilation, ensuring hygiene and comfort while enabling urine recovery.
Effective separation of effluents
The patented system uses a pedal-operated conveyor belt to automatically separate liquids (drained by gravity) from solids (conveyed to a biological technical room).
Autonomy strengthened by expertise
Our solutions are designed and scaled according to the actual usage of each site in order to offer optimal autonomy. Our service contracts then ensure the long-term performance of the installations, providing operators with peace of mind.
Biological treatment and urine recovery:
Biological treatment of solid matter is carried out through vermicomposting, a natural process based on the action of earthworms. When recovered, urine can be stored and then directed to appropriate recovery channels.
This operation enables controlled flow management, without water, with reduced environmental impact.
User comfort and enhanced hygiene
Designed to be understated, PRM accessible, and hygienic, the cabins feature natural odor-free ventilation, low-level lighting, and gel and toilet paper dispensers, providing an experience comparable to a flush toilet.
A measurable environmental impact, sustainable and positive
Each Sanisphere installation helps preserve natural resources by reducing water consumption and emissions linked to sanitation.

Frequently Asked Questions about our public dry toilets
How do Sanisphere toilets work without water or electricity?
Sanisphere technology is based on a patented principle of separation of solid and liquid waste. A simple press on a pedal activates a self-cleaning mechanical system that evacuates solids to a vermicomposting area. Liquids are directed to a separate drainage circuit. This ingenious system, combined with natural ventilation, ensures autonomous and ecological operation.
Are there odors in the cabins?
No, there are no odors. The design of our toilets creates a natural airflow that draws air from the cabin through the bowl, preventing any odors from rising. The immediate separation of urine and feces also prevents the formation of ammonia, the main source of unpleasant odors.
Finally, a natural “blotting” effect is established within the system: a microbial film develops and captures odorous gases, helping to maintain a healthy and odorless cabin.
Is SANISPHERE toilet maintenance complicated?
No. SANISPHERE toilets are designed to make maintenance as easy as possible for municipalities and cleaning crews.
The cabin is easy to clean thanks to its smooth, seamless surfaces, which allow for quick cleaning, even with plenty of water. The absence of water and a sewage system also prevents the common problems associated with traditional restrooms: leaks, overflows, or water marks on the floor.
The material is processed using a biological treatment system. This natural ecosystem, composed of microorganisms and worms, gradually breaks down the material and significantly reduces its volume. As a result, the compost only needs to be emptied, on average, every 10 to 15 years.
For even greater peace of mind, SANISPHERE also offers maintenance contracts that enable local governments to ensure the longevity and proper operation of their systems.
Are Sanisphere toilets hygienic and comfortable?
Absolutely. Each cabin is designed to provide optimal comfort, with the following features:
Amenities included: They are clean, modern, and equipped with a hand sanitizer dispenser and toilet paper.
User experience: Use is similar to conventional toilets, making them very intuitive.
Visual cleanliness: The absence of sawdust and a specific design (including lighting) conceal the technical components, ensuring a pleasant experience.
Are your installations accessible to people with reduced mobility (PRM)?
Yes. Most models are accessible to people with limited mobility:
Specific product line: The SANITER line, in particular, is designed to provide accessibility for people with reduced mobility.
Amenities: The cabins have grab bars and sufficient maneuvering space.
Adaptability: Options such as manual pedal operation (instead of foot operation) are available to facilitate use by everyone.
Why choose Sanisphere over another dry toilet solution?
Sanisphere stands out for its experience and status:
Pioneer of eco-responsible public toilets since 1991.
Sawdust-free technology with unique and patented separation.
SCOP-type company, committed to quality, sustainability, and innovation.
Offers a complete solution (from design to maintenance) with “Made in France” expertise and ISO 9001 certification.
What happens to urine and solid waste?
- Solid Waste
They are processed directly in the toilet through a biological treatment process (earthworms and microorganisms) that breaks down the material and reduces its volume by a factor of 7 to 10. This natural system is self-sustaining, highly resilient, and functions even in challenging environments such as high altitudes. If the system is emptied before the material has fully decomposed, the compost can be sent to an approved composting facility. - Urine
Three solutions can be offered to the customer depending on the site’s configuration: (1) connection to the public sewer system, (2) the installation of a drainage system following primary treatment in a pretreatment tank, or (3) the storage of urine in certified tanks for reuse as fertilizer through approved channels.
