Power Option: With Battery
The CompoCloset S1 is a battery-powered dry flush sealing toilet with a built-in urine diverter that keeps liquid and solid waste separate. By sealing only solid waste, the S1 helps reduce bag use compared with traditional sealing toilets that bag everything together. It is designed for off-grid use in vans, RVs, boats, and compact spaces where water-free operation and simple waste handling matter.
The urine diverter routes liquid waste into a removable bottle, while the internal heat-sealing system discreetly seals solid waste out of sight. An LED urine level indicator helps signal when the urine bottle is full, and sturdy side handles make the unit easier to move when needed. The toilet is available in white and black finishes.
The S1 uses no water. The heat sealing system runs on a rechargeable 12V Li-ion battery, and the urine level indicator uses a 9V battery, not included. One cartridge liner bag is included.

Liquid waste is directed into the urine bottle, while solid waste is sealed with the battery-powered heat-sealing system. This separation helps reduce odor, limits unnecessary bag use, and keeps waste out of sight until emptying.
The S1 uses a built-in urine diverter to keep liquid and solid waste separate, so only solid waste is sealed and bagged.
No. The S1 is a water-free toilet and does not require water to operate.
The heat sealing mechanism runs on a rechargeable 12V Li-ion battery. The urine level indicator uses a 9V battery, which is not included.
For two people, the 1.7-gallon urine bottle typically needs emptying every 1–2 days. An LED indicates when it’s full.
The S1 includes one cartridge liner of bags for getting started.
The S1 measures 17.0 inches deep, 15.2 inches wide, and 16.5 inches high, and weighs about 29 pounds.
If you run out of liners, the S1 continues working as a standard urine-diverting toilet, but won’t seal solid waste until you install a new liner roll.
The rechargeable battery provides 20+ seals per charge.
Liner rolls cost approximately $15–$20 and provide around 25 flushes per roll.
A two-year warranty on manufacturing defects.

Works great, no smell, easy to empty
Great product. Used daily in my build— ac fan solar….
Great products, responsive team!
What can I say? Orion takes great care of their customers. They went out of their way to help me and I appreciate it. I also found out too late that they sell 8020 Roll in nuts. I use the 10 series for my build. The nice thing about Orion‘s 10 series rolling nuts is they have a register on top of the nut that keeps it from twisting in the extrusion. I wish I would’ve known this when I bought all my hardware. I would’ve definitely bought this product from Orion. Check them out.
Kaiya provided wonderful support for a troublesome panel struggling during a second year of operation -- I could not be more pleased to have chosen Orion for my solar! The Stealth rack & awning are quite sweet as well :). Thanks Orion!
So far so good. Installed on my Sportsmobile converted dodge promaster. Waiting for the rain to see how it does in wet conditions. Once I figured out how to install it was VERY easy. Only ask would be more details on initial installation process since I wasn't sure exactly where to place the track. Once I got it installed and put the fly in the track it was so easy. Excited for how this will work on my pop-top van.
