S1 Dry Flush Sealing Toilet Debut at Overland Expo

CompoCloset will debut the S1 Dry Flush Sealing Toilet for the first time at Overland Expo SoCal. The patent-pending S1 is a urine-diverting sealing toilet designed as a cleaner, simpler alternative to traditional black tanks and chemical systems.

Unlike conventional bagging toilets, the S1 separates liquid and solid waste at the source, then heat-seals solids for hygienic, odor-controlled disposal. 

Also on display will be CompoCloset’s Cuddy self-contained composting toilet and Cuddy Lite portable composting toilet — both designed to eliminate black tanks and simplify off-grid living.

Built for vans, truck campers, RVs, and expedition vehicles, CompoCloset systems help overlanders stay out longer with greater comfort and independence.
