A self-sustaining, self-contained, dry toilet system powered by nature.
Kazuba™ toilets are engineered with a patented system that operates without water, chemicals, or electricity. At the core of this technology is Kazuba’s™ desiccating system—a watertight, dry toilet solution that utilizes natural elements to process waste efficiently.
The system employs a constant airflow mechanism, leveraging temperature and pressure gradients to facilitate the evaporation of urine and the dehydration of solid waste. This process significantly reduces waste volume, making the system highly efficient and low-maintenance.
Constructed from recyclable materials, Kazuba™ toilets are designed for durability and environmental sustainability. The cabins are built with heat-treated Thermowood™ pine, providing exceptional resistance to the elements and ensuring longevity.
This innovative approach results in a toilet system that is odourless, easy to use, simple to clean, and requires minimal maintenance, offering a sustainable and efficient alternative to traditional flushing toilets.
Kazuba™ dry toilets harness the power of the sun and wind to create a self-sustained, zero-discharge system. Liquids are separated from solids, allowing natural aeration to evaporate urine and dehydrate solids, reducing volume by up to 90%. A wind-driven vent and thermal chimney work together to maintain continuous airflow. Fresh air is drawn through the pedestal while odours are extracted, ensuring an odour-free experience. This passive ventilation system works without electricity, chemicals, or bulking agents—maximizing capacity and minimizing maintenance. Designed for reliability, Kazuba™ toilets offer a sustainable, low-maintenance alternative to traditional sanitation.
Kazuba™ designs autonomous dry toilets that operate without water, sawdust, chemicals, or electricity, using only sun and air. This eco-friendly system reduces water consumption and eliminates effluent discharge, making it a sustainable alternative to traditional toilets.
In New Zealand, Kazuba™ provides a game-changing dry toilet solution with no water, sewer or power for parks, trails, and remote locations where conventional infrastructure is impractical. By eliminating wastewater discharge and slashing resource consumption, Our innovative passive technology actively protects Aotearoa’s waterways and natural ecosystems.
Built for durability and designed for the future, Kazuba™ is driving real change in waste reduction and environmental resilience.
Thousands of Kazuba™ dry toilets are in use globally — installed in parks, beaches, parking lots, bus terminals, golf courses, hiking trails, wildlife parks, and more.
Planning a project and want to see a Kazuba™ near you? Ask WCTNZ® about installations and references in your region.
Ask about installations near meThe three things that stall a public-toilet purchase — will it be accessible, will it pass consent, and what does it cost to keep running — answered plainly.
It depends on the model — and there are accessible KL2 building options for councils and organisations that need an accessible public toilet facility.
Zero effluent discharge — no water, chemicals, bulking agents or electricity — which is what makes Kazuba™ suitable for environmentally sensitive sites where conventional wastewater systems are difficult, undesirable or not permitted, including near sensitive waterways. Best considered early in the site-planning process so placement, access and long-term servicing can be properly allowed for.
Liquids evaporate and solids dehydrate, reducing volume by up to about 90% — so servicing stays low. Buildings use a galvanised steel frame with Thermowood® pine cladding and recyclable materials. Permanent KL installations are managed by WCTNZ®; relocatable Bumper units are professionally installed by WCTNZ®, with a relocation service when your site changes.
For a specific accessibility standard on your project, WCTNZ® will confirm the unit's compliance before you specify it.
Ask about compliance for your siteAn above-ground relocatable unit and an in-ground permanent series — both powered by sun and wind, with zero effluent discharge. Match the format to your site, then ask us about the unit.
(Above Ground)
Best for: seasonal, event-based and multi-site use — golf clubs, vineyards, wedding venues, campgrounds, parks and festivals, or anywhere a permanent building isn't the right answer. Fast to deploy and relocatable by WCTNZ® when your site changes.
(In-ground)
Permanently installed dry toilet facilities. The tank is installed into a flat concrete slab, anchoring the system and allowing for easy access at ground level.
Best for: permanent public sites — parks, reserves, beaches, walking tracks and long-term commercial locations. From the compact KL1 for track-side and alpine sites to KL2 accessible buildings, with an optional urinal stall for high-traffic locations.
Capacity depends on the model and how busy the site is, and the ~90% volume reduction keeps servicing low. Like all drying toilets, capacity and performance are climate dependent — so we size each project on its site, not on a generic table.
~90%
less solid volume — liquids evaporate, solids dehydrate. No water, chemicals or power.
Established in early 2000s France, Kazuba™ dry toilets offer a sustainable, waterless alternative to traditional systems, minimizing environmental impact without sacrificing comfort.
Powered by sun and wind, Kazuba™ systems operate entirely off-grid with no effluent discharge. Built for public outdoor use, Kazuba™ toilets are durable, recyclable, and feature sustainably sourced wooden cladding.
Designed for both permanent and relocatable installations, Kazuba™ dry toilet cabins are perfect for seasonal or year-round use, suiting remote parks and reserves, high-traffic areas, sensitive environments, and eco-conscious organizations.
Ideal for campgrounds, glamping and adventure sites, golf courses, vineyards, and nature reserves, Kazuba™ provides a reliable, off-grid, eco-friendly solution for public and commercial applications.
Communities are choosing dry toilets because they are more economical, more ecological and easier to maintain.
Driven by commitment to sustainability and eco-conscious design, Kazuba™ was founded in early 2000s France, and created a self-contained dry toilet system that utilises nature’s power to manage waste without producing effluent discharge.
Kazuba’s™ commitment to pioneering eco-friendly sanitation solutions was acknowledged in 2010 when the company received the Innovation Award in the Urban Planning category at the Salon des Maires et des Collectivités Locales in France. This accolade highlighted the effectiveness and ingenuity of Kazuba’s™ patented desiccating system.
Today, Kazuba™ continues to lead in sustainable sanitation technology, offering autonomous, dry toilet systems that operate without the need for water, electricity, or chemicals. Thousands of Kazuba™ dry toilets are in use globally—installed in parks, beaches, parking lots, bus terminals, golf courses, hiking trails, wildlife parks, and more!
The questions procurement teams, park managers and campground operators ask before they specify a Kazuba™.
No. Kazuba runs entirely off-grid on sun and wind, with zero effluent discharge — no water, chemicals, bulking agents or electricity. That's exactly what makes it suit sites where conventional infrastructure isn't practical.
Liquids are separated from solids so natural aeration can evaporate the urine and dehydrate the solids, reducing volume by up to about 90%. A wind-driven vent and thermal chimney keep air moving constantly, drawing fresh air in and extracting odours — so it stays odour-free.
It depends on the model. The above-ground Bumper installs on flat ground with a 200mm recess or an accessibility ramp; the in-ground KL tank systems sit in the ground, so access is direct at ground level. For a specific accessibility standard on your project, WCTNZ will confirm the unit's compliance before you specify it.
It depends on the model and how busy the site is, and the ~90% volume reduction keeps servicing low. Tell us your expected visitor numbers and we'll help size the right unit and set clear service expectations.
Both. There's an on-ground portable option (The Bumper) and an in-ground unit on a concrete slab (KL Series), suited to seasonal or year-round use.
Kazuba is French-engineered, established in the early 2000s, with thousands installed worldwide in parks, beaches, trails and more. In New Zealand it's supplied and supported by WCTNZ.
Tell us your organisation, site type, expected visitor numbers, region and rough timeframe — our buildings team will come back with the right Kazuba solution. No obligation.
