CompoCloset, a leader in portable composting and eco-friendly toilets, announced the launch of its newest innovation: the S1 Sealing Toilet — a urine-diverting dry flush toilet — now live on Kickstarter.
The Problem With Current Off-Grid Toilets
According to CompoCloset, traditional dry flush toilets bag all waste together, requiring frequent emptying, expensive refill packs and generating significant plastic waste. Composting toilets are sustainable but aren’t the right solution for everyone.
The S1 changes that. It separates urine from solids, reducing bag use by up to 80%, lowering running costs and extending off-grid adventures without sacrificing hygiene or convenience.
“We set out to fix the dry flush toilet for real-world off-grid living. The S1 isn’t just cleaner — it’s smarter, more sustainable, and built for life on the move,” said Richard Peter, CompoCloset founder.
S1 Sealing Toilet: Key Features
- Urine Diversion Technology — separates liquids to reduce plastic use and odor
- Powerful Sealing Mechanism — locks away solid waste after every use
- Compact and Portable — fits into smaller spaces while staying rugged and durable
- Long-Lasting Battery — up to 50 flushes per charge

The S1 is ideal for camper vans, RVs, boats, glamping setups, tiny homes, cabins and residential care applications — anywhere a clean, chemical-free, waterless toilet is needed.
