Why a composting toilet is the ideal garden toilet
In German allotment gardens, the Federal Allotment Garden Act stipulates that no wastewater may be generated. Conventional flush toilets are therefore not an option. At the same time, garden owners desire a hygienic, odor-free solution that blends seamlessly into the garden environment.
This is precisely where modern dry toilets come in: The consistent separation of urine and solids prevents unpleasant odors. The natural composting process transforms the solid waste into valuable humus for ornamental plants. A win-win situation for people and nature.
Key benefits for the garden
- 100% self-sufficient : No water, electricity or sewage connection required.
- Odorless : Patented sealing technology prevents ammonia formation
- Weather-resistant : High-quality materials for year-round outdoor use
- Flexibly expandable : Modules for different user groups and capacities
- Easy emptying : Ergonomic containers with secure closures
Installation requires no tools and takes place on a level surface. Whether in an existing garden shed, a separate toilet cubicle, or as a freestanding system – BioTioo composting toilets adapt to the circumstances.
From allotment gardens to clubhouses: solutions for every need
BioTioo composting toilets were specifically developed for the unique requirements of garden use. The modular system allows for individual configurations depending on available space and usage intensity.
For the private allotment garden
BioTioo models without electricity, using a bag system and bedding material, are sufficient for occasional use. No installation is required. The containers can be easily transported to your home compost heap or alternatively disposed of via your organic waste bin and general waste.
For garden clubs and community gardens
If several people regularly use a toilet, a UTA (Ultra-Free Urine) variant is recommended. This uses an adapter instead of a urine tank, which directs the urine into an external tank. This significantly extends the emptying intervals.
For garden houses with overnight accommodation
Those who regularly use their garden as a retreat or workspace opt for maximum comfort: models with an agitator and SmellX odor trap enable continuous, odor-free operation. Perfect for garden sheds with self-sufficient water supply.
