The Air Head Compact is the go-to composting toilet for serious van builders and liveaboard boaters. Its small footprint, sealed construction, and 12V fan make it one of the most practical composting toilets for tight, wet spaces — it fits where the Separett Tiny can't.
Urine-diverting design keeps solids dry for odour-free composting. The stainless steel agitator handle mixes bulking material (coco coir) through the solids tank to maximise capacity. The sealed, moisture-resistant body handles humid environments without complaint.

Why Van Builders Choose It
Low 12V power draw means a 100Ah battery runs the fan for over two weeks without a recharge. The sealed body tolerates the damp environment of a wet-room-style van bathroom. Available with a flat-back (hull) tank for installation flush against a wall or curved surface.
