The S1 Dry Flush Sealing Toilet redefines off-grid sanitation with an advanced battery-powered heat sealing system designed for modern overland, van life, RV, and remote camping setups. Built for convenience and hygiene, the S1 offers a cleaner and more efficient alternative to traditional portable or composting toilets.
Unlike standard dry flush systems, the S1 features an integrated urine diverter that separates liquid and solid waste, keeping the system cleaner and significantly reducing odors. This innovative design ensures that only solid waste is sealed inside the liner bags, allowing you to use fewer bags and reduce ongoing operating costs.
The S1’s heat sealing mechanism securely encloses waste after each use, keeping it odor-free, hygienic, and out of sight until disposal. The battery-powered design makes it ideal for off-grid living, overlanding, van conversions, RV travel, boats, and remote campsites where traditional plumbing systems aren’t available.
Designed for durability and ease of use, the S1 Dry Flush Sealing Toilet delivers a modern sanitation solution for adventurers who want comfort, cleanliness, and reliability wherever their travels take them.
Each unit includes one cartridge liner of sealing bags so you’re ready to start using the system right out of the box.
