The Biolan Simplett Separating Toilet is a urine-separating toilet designed for both indoor and outdoor use.

Solves Odor Problems at the Source

Thanks to its urine-diverting design, the Biolan Simplett tackles the main cause of compost toilet odors—moisture mixing with solids. By keeping liquids and solids separate* right in the seat, you avoid bad smells.

For optimal operation, simply add a Bulking Material for Composters and Dry Toilets.

This dry bedding helps absorb moisture, reduces odors, and enhances the composting process. Before using the toilet, place a layer a couple of centimetres thick on the bottom of the inner receptacle. The dry material does not need to be added after every use—adding it after defecation is sufficient to maintain hygiene and ensure smooth functioning of the toilet.

The dry separating toilet ensures that both liquid and solid waste are transformed into reusable materials, enhancing its eco-friendly features.

Smart Sanitation for Small Spaces

Whether you’re fitting out a tiny house, garden shed, cabin, or off-grid retreat, the compact size (51.5cm x 52.5cm x 56cm) makes the Simplett ideal for tight spots—without compromising comfort, thanks to the thermal seat that eliminates cold shock year-round.

Easy to Maintain in Minutes
