The Air Head Classic is the full-size waterless composting toilet trusted by van builders, overland travellers, and liveaboard boaters worldwide. It separates liquids and solids at source — no chemicals, no macerator, no connection to water or sewage — just a clean, odour-free system that works wherever you are.

The Classic model features a full household-sized seat for genuine comfort, making it the go-to choice for builds where space allows and long-term comfort is a priority. The same proven design runs in ocean-crossing yachts and full-time campervans alike.

How it works
A built-in urine diverter sends liquids forward into a removable 7-litre bottle while solids fall into the rear tank. A continuously running 12V fan draws air through the solids chamber, drying the material and venting any moisture outside through a standard 40mm hose. No smell, no fuss. Empty the liquids every 2–3 days and the solids every 3–4 weeks for two people full-time.

Why the Classic over the Compact?
The Classic seat is full household size — wider and deeper than the Compact's marine-style seat. If your build has the floor space (483mm depth vs the Compact's 445mm), the Classic gives a noticeably more comfortable day-to-day experience. For tighter van builds, see the Air Head Compact.
