Nature Loo™ Alectura takes the proven low-profile batching concept and develops it into a stronger, more serviceable residential composting toilet system for tiny homes, baches and other buildings with restricted underfloor space.
The design retains the advantages that made earlier split systems attractive—a familiar pedestal, treatment outside the bathroom and rotating chambers—while improving moisture control, access, security and chamber handling.
Alectura is available in Comfort and Premium packages, allowing the project to choose between the core batching architecture and a higher-specification configuration with active mixing and an Ezylift trolley.
The short answer
Alectura is WCTNZ®'s current low-profile residential batching direction, designed around approximately 500 mm of underfloor clearance.
Comfort provides the core dual-wall chamber system. Premium adds dual mixer blades and an Ezylift trolley for owners wanting greater pile management and easier chamber movement.
One chamber in service, another resting
Alectura uses two 90-litre composting chambers in rotation. One chamber sits beneath the pedestal and receives material. When it reaches its service point, it is capped and moved out of active use while the second chamber is connected.
The resting period allows decomposition and stabilisation to continue without fresh waste being added. The actual rotation interval depends on occupancy, loading, climate and operation.
Batching separates collection from resting time. The value comes from the rotation as a complete process—not simply from having two containers.
What remains from the successful split-system approach
- Porcelain pedestal: a comfortable, familiar fixture in the bathroom.
- Dual-wall chambers: structural support with a separate inner air and liquid pathway.
- Active ventilation: a 12V fan and vent route draw air through the toilet system.
- Excess-liquid management: liquid passing through the chamber is directed to the system's specified receiving pathway.
- Processing outside the room: the composting volume and routine chamber work remain below the floor.
What Alectura adds
Removable internal chamber
The internal component can be removed to improve access for inspection and deep cleaning when required. That makes the chamber more serviceable than a permanently enclosed internal structure.
Moisture-managing base wicks
Wicks in the base can draw some liquid back toward the composting mass, helping the system retain useful moisture while the broader drainage pathway manages excess.
Stainless-steel locking ring
The locking ring secures the lid to the chamber, supporting containment and reducing the risk of accidental access by children or animals while a chamber is resting.
Inspection plug
An out-of-service chamber can be checked without removing the complete lid, making it easier to observe moisture and treatment progress.
These features support operation; they do not remove the need for correct bulking material, ventilation, realistic loading and a suitable resting period.
Nature Loo™ Alectura Comfort
The Comfort package provides the Alectura batching architecture with two dual-wall 90-litre chambers, ventilation components and a porcelain pedestal.
It is the value-focused choice for projects wanting low-profile split-system capacity without the Premium mixing and trolley package.

Nature Loo™ Alectura Premium
Premium adds dual mixer blades that extend into the composting mass. Mixing can level the pile beneath the chute, redistribute carbon material and make better use of chamber volume.
It also includes the Ezylift trolley, giving the owner a dedicated method for lifting and moving chambers around a suitable service area.

Which Alectura package suits the project?
| Consideration | Alectura Comfort | Alectura Premium |
|---|---|---|
| Core chamber system | Two 90L dual-wall batch chambers | Two 90L dual-wall batch chambers |
| Underfloor direction | Low-profile, approximately 500 mm clearance | Low-profile, approximately 500 mm clearance |
| Internal mixing | Manual chamber management without Premium mixer package | Dual mixer blades in the chambers |
| Chamber handling | Plan a suitable owner handling method | Ezylift trolley included |
| Best fit | Projects prioritising the core batching system and value | Projects seeking active mixing and dedicated chamber movement support |
Low-profile does not mean no service space
The chamber sits below the toilet pedestal, so the building needs a short, vertical chute and a firm service area. The stated clearance must be considered alongside lids, pipework, chamber movement and the person doing the work.
The chamber area should be protected from flooding and uncontrolled weather exposure. Ventilation and liquid-management components need to be accessible for inspection.
For a tiny or transportable home, resolve the toilet before finalising the trailer, piles, floor beams and bathroom position.
Certified product evidence supports the specified model
The Alectura range is certified to AS/NZS 1546.2:2008 under SAI Global licence SMKH25591. That product evidence supports the named models within the scope of the certification.
Certification does not approve the entire building or site by itself. Foundations, ventilation, liquid management, residual handling, greywater and the relevant project pathway still need to be addressed.
Nature Loo™ Alectura FAQs
How much underfloor clearance does Alectura need?
The system is designed around approximately 500 mm clearance. The project should also provide practical working room for the chamber, lid, connections and maintenance.
What is the difference between Comfort and Premium?
Both use the Alectura dual-wall batching chambers. Premium adds dual mixer blades and the Ezylift trolley.
Can Alectura suit a permanent tiny home?
It is specifically aimed at low-profile residential buildings such as tiny homes and baches. Confirm the actual occupancy, climate and chamber-access arrangement before selection.
Does the material finish composting inside the active chamber?
The active chamber receives fresh waste. Further treatment continues while a chamber is out of service. Final handling depends on the system guidance and the condition of the material.
Does certification guarantee council acceptance?
No. It provides product evidence for the model. The complete project and its wider sanitation pathway remain site-specific.
Is Alectura right for your building?
Send WCTNZ® the expected occupancy, floor construction and underfloor clearance. We can help compare Comfort and Premium before the structure is finalised.
