CompoCloset S1 Dry Flush Sealing Toilet – 12V (No Battery)

Overview 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. Two high barrier liners and a power cable are included. Important Info The S1 uses no water. This version has no internal battery and requires an external 12V supply. It is not compatible with 24V systems or direct household power. The urine level indicator uses a separate 9V battery, not included. Prefer a rechargeable battery?
