Kazubaloo KL2

Kazubaloo KL2 Waterless toiletThe Kazubaloo KL2 is a waterless toilet designed for regular use and is suitable for reduced mobility users.

Suitable for the most demanding climates and conditions the KL2 is a completely 'off-grid' toilet system which does not require access to the sewerage or electricity systems and does not use any chemicals.

The Kazubaloo KL2 works by dehydrating the solids and evaporating the liquids in order to reduce waste volumes by up to 90%. Waste is transformed into a neutral, odour free material in a completely ecological process. The unique chimney and the evaporation process creates an air flow which radically reduces odours in a way which is not possible with a conventional composting toilet.

The KL2 can be installed as a single, standalone unit, or in series as a block. When installed in series, the Kazublaoo units are linked internally to balance load.


All units are assembled on site, the whole operation, usually taking a day.

The KL2 frame is a steel structure comprised of lower and upper rigid rings separated by six rectangular section posts. Steel bands fixed to the posts in turn support tongue and groove, wood cladding.

The steel frame is entirely galvanised for longevity and the wood cladding is treated to class 4 for external use. A curved door, also constructed in galvanised steel, opens on a sliding mechanism, fixed at four points for maximum stability. The near flat roof is usually finished in wood but can accommodate other materials as the situation demands.

Once the structure is in place, the lower ring is usually filled with concrete to provide a solid flooring. Foundations can be sharp sand, earth or gravel making the KL2 suitable for ecologically sensitive sites.

Kazubaloos are simple enough for experienced building professionals to install.

In the last few years Woo Woo has refined the installation method, which is explained in detail in the installation documents. We can provide both guidance notes on what to look for from contractors and comprehensive step-by-step instructions that explain how to install the toilet system and cabin. If you would like we can recommend a contractor to you if we have worked with one in your area.


The Kazubaloo Toilet System is made from UV protected low density polyethylene unit and comes with a two year Manufacturers Guarantee. It has a design life of at least 50 years.

The KL2 cabin is made from a galvanised steel frame covered with ThermoWood cladding. The steel frame has an Anti Corrosion Treatment and a design life of 25 - 50 years.

The cladding material, ThermoWood®, is produced by heat treating Finnish grown pine to temperatures in excess of 200 degrees Centigrade. During heat treatment, chemical and structural changes occur within the timber which alter and improve some of its basic characteristics. The resulting product is a more durable and stable timber, an ideal material for use in exposed areas.

The heat treatment process provides ThermoWood with a service life of up to 30 years without the need for a chemical preservative. This is twice as long as the Class 3 treated Pine that is typically used for cladding - generally guaranteed for only 15 years against rot.

The roof is made from 17mm Smartply® coated on both sides with a white 0.8mm GRP (fibreglass) skin and has a 15 year design life. The edge of the roof is painted with a white exterior grade paint and should be repainted every 3 years.

ThermoWood is PEFC-certificated which ensures the raw material is sourced from sustainable managed forests. Total Volatile Organic Compound (TVOC ) emissions values are significantly lower than those for untreated softwoods due to the evaporation of most of the terpenes during heat treatment process.

SmartPly OSB is made from sustainable, fast-growing timber. They only use forest thinnings of new-growth pine and spruce, including the tops which are not used to make any other wood-based product. SmartPly is increasingly being used instead of plywood, which by contrast uses large logs cut from old growth forests.
