Clivus Multrum™ began in 1939 when Swedish innovator Rikard Lindström built the first modern composting toilet—an inclined, continuously fed chamber designed to work with nature, conserve water, and keep waterways clean. 

Evolving from Lindström’s original design, Clivus Multrum™ is now the world’s leading brand in composting toilets and waterless sanitation. Designed by the best engineers in the field and refined through decades of real-world use, it sets the benchmark for reliability, simplicity, and long service life.

At its core, Clivus Multrum™ uses a porcelain bathroom pedestal connected by a straight chute to an underfloor composting chamber. The inclined (“clivus”) chamber and continuous ventilation create a stable aerobic environment where waste breaks down over a long retention time—delivering odour-free operation and a soil-like end product. Moisture is manage either via approved soakage; or, where discharges are constrained, zero-discharge recirculation options enable a closed-loop, zero-leachate solution.

Available in configurations and sizes to suit everything from a residential family home to higher-use commercial operations and council bathroom facilities, Clivus Multrum™ scales effectively while keeping maintenance straightforward.

Typical applications include off-grid homes, baches, eco-residences, remote cabins, lodges, glamping sites, marae, alpine huts, trailheads and multi-day hiking treks; visitor centres, campgrounds, council facilities and DOC sites—anywhere reliable, waterless sanitation is needed with minimal ongoing intervention.
