Version:
The CompoCloset S1 is a 12V-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. This version has no internal battery and requires an external 12V supply (11-14V). It is not compatible with 24V systems or direct household power. The urine level indicator uses a separate 9V battery, not included. Two high barrier liners and a power cable are included.

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.
Love it! I researched a lot before deciding on Orion. I just think their design out looks all the others. This is functional, solid, and easy install. Customer service was excellent. They answered all my questions. I didn’t build my van, I bought it already done. Solar panel and all, I was able to move the solar panel to a better location using their solar panel brackets, I’ll easily add some decking following their recommendations of what decking product to use, and be able to store items I don’t want in the van. Love supporting a local Oregon business. Would recommend them to everyone. Oh and I got the rack with the lights. Totally recommend. The install was perfect and they really light up the night!
Thank you, Krysta! It’s so great to see everything come together on your van. We’re glad we could help you get the solar placement dialed in and plan for decking and extra storage. And thank you for sharing the videos showing off the rear scene lights and flush solar brackets; they’re a huge help to others planning their setups! We really appreciate your recommendation and support for a local Oregon business. Enjoy your adventures!
The ladder is awesome. Super solid. Customer service was also super awesome. Answered my zillion questions quickly through email. Orion products just look so sleek and … stealthy. Glad to support a local business as well. Maybe that’s why shipping was next day.
Hi Krysta, thank you for the video! Glad you love it! Made in Oregon!
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.
