Boxio | Composting Toilets & Portable Sinks

Boxio is a German camping brand built around a single clever idea: a complete off-grid sanitation kit that fits inside a stackable Eurobox. Designed and produced in Rostock on Germany's Baltic coast, Boxio gives vanlifers, caravanners, and tent campers a cleaner, simpler alternative to chemical toilets and battery-powered wash systems. The range is small, neatly engineered, and built around one shared 40 x 30 cm footprint, so every product stacks, slots, and travels without fuss.

Who makes Boxio and where are the products made?

Boxio is a brand of Duschkraft GmbH, a Rostock-based start-up founded in 2017. Co-founder Arvid Reinwaldt developed the concept after struggling to find a fair-priced dry separating toilet for his self-built tiny house. Production sits in Rostock, with around 95% of components manufactured in Germany using recycled plastic.

Two products sit at the heart of the brand. The Boxio Toilet is a dry separating toilet (also called a urine-diverting or composting toilet) that keeps liquids and solids apart in two sealed containers. No water, no chemicals, no holding tank to empty at a service point. The Boxio Wash is a hand-pumped portable sink with a 5-litre fresh water tank and a separate wastewater container, running on 3 to 10 pumps of an air-pressure handle. Both products share the same Eurobox footprint, so the Toilet stacks directly on top of the Wash to form a compact bathroom in two boxes, with the Solo Up riser, Cool passive cooler, and other Eurobox-format accessories slotting into the same modular system.

Boxio appeals to a specific kind of camper: vanlifers, day-van and micro-camper owners, narrowboat users, allotment holders, and tent campers who want off-grid sanitation without committing to a permanent install. The kit also suits roof tent owners, garden-room users, and households wanting a backup loo for power cuts or building works. Because nothing needs plumbing or wiring, the products can be packed away and stored when not in use, then redeployed in a different vehicle, shed, or pitch without modification. For specific product details and stock, head over to the Boxio Toilet, Boxio Wash, and Boxio Accessories collections.

If you're new to dry separating toilets, the Boxio Toilet Plus or Toilet Max Plus starter kits are the standard entry points. For handwashing without plumbing, the Boxio Wash or Wash Plus covers most needs. Pick the Plus variants when you want everything included for first-time setup; pick the standalone Toilet or Wash when you already have accessories or just need the core unit. The Solo Up riser is worth adding if seat height matters or you want under-toilet storage for hemp litter, bio bags, and toilet roll.

The main consideration before buying is honest storage planning. The 40 x 30 x 28 cm Eurobox fits most vans and motorhomes, but headroom for the lid plus Solo Up needs checking. The system isn't compatible with Tanos Systainers or the Sortimo shelving system. The Wash isn't approved for storing drinking water, so plan a separate water source or pair it with the Boxio Water Filter for filtered drinking water. Keep hemp litter dry, empty canisters regularly, drain tanks fully before frost, and use the Plug whenever the toilet's in transit. Get the basics right and the kit handles years of off-grid use without fuss.
