    Please select the primary pedestal (toilet fixture) option you would like to accompany your composting system.

    Note; that the Urine-Diversion (UD) pedestal option is most suitable where there is high use in peek or large family gatherings.

    Note; that with Urine Diversion, it is recommended that the compost mass is kept wet to avoid the pile drying out. Consider getting the hand-held bidet sprayer accessory for facilitating the hydration of compost.

    A hardwearing Nano-Ceramic Non-Stick Coating is applied onto the inner side of the Pedestal (toilet fixture) for maximum cleanliness.

    Note; basic cleaning will still be required.

    Note; non-stick is hydrophobic and repels liquids only.

    All ELV (Extra Low Voltage) (12v-48V) are suitable for Off-grid power systems.

    You may need additional vent materials depending on how many storeys your building has.

    Single Storey buildings with a high-profile roof (A frame or mono-pitch) require extra lengths of vent pipe - add one 800mm Vent Pipe Extension

    Double Storey buildings require extra lengths of vent pipe. Please add 4 x 1m Vent Pipe Extensions.

    Double Storey building with a high-profile roof (A frame or mono-pitch) require extra lengths of vent pipe - add one 800mm Vent Pipe Extension

    Kit for stepping the vent stack around the eaves of the roof. Allows you to avoid penetrating the roof.

    A wind-driven vent offers the best redundancy for your system ventilation. The wind-driven vent will assist the fan under heavy wind conditions, keeping the system operational in the event of a power outage or fan failure.
    SharkVent™ | Wind Ventilator has high efficiency with a linear wind direction windvane (good for storm-prone areas).
    Universal Vent ACC | Wind-Driven Vent has high efficiency in low windage. 2 colours: white or black.

    Select this reducing collar to adapt the vent from 150mm to 100mm.

    Choose how you'd like to manage the liquid (leachate) produced by your composting toilet system:

    Discharge to Drain or Trench
    Divert excess leachate to an approved soakage trench, drain field, or dispersal area. This option is suitable for most installations with available drainage capacity and may require a resource consent under the Resource Management Act 1991 (RMA), depending on your local council’s rules.

    Zero Discharge System (Reticulation)
    Select our sealed zero-discharge system to recirculate leachate back into the composting chamber for evaporation or absorption. Since no liquid is discharged to land, water, or air, this option falls outside the scope of the RMA and typically does not require resource consent. Ideal for sensitive environments, remote sites, or areas with strict discharge regulations.

    System sizes with Automatic or Manual reticulation dosing cycle options
    Automatic operations are on timer, and Manual operations are user-operated.

    Small 80L system - Suitable for a light-use system 
    Large 450L system - Suitable for a heavy-use system

    Product background

    Continuous composting in a lower-profile tank

    CM8 Next-Gen brings a true continuous underfloor composting chamber into projects where available clearance is tighter.

    The Next-Gen design increases usable composting volume while reducing the required underfloor clearance to approximately 830mm.

    Best suited for

    Smaller homes and remote low-clearance sites

    • Sustainable off-grid residences.
    • Small homes and tiny houses.
    • Holiday houses.
    • Walking trails.
    • Remote workstations.
    • Sites where lower underfloor clearance is important.
    Key system features

    Designed for long-term continuous operation

    • Continuous composting format with low routine maintenance.
    • Sloped internal geometry supports compost movement and usable volume.
    • Leachate-storage design helps reduce drainage-system blockage risk.
    • Passive ventilation supplements the powered fan and provides airflow redundancy.
    • Structural tank suitable for applicable inground installation pathways.
    Package includes

    CM8 Next-Gen package

    • Fully assembled composting tank.
    • Porcelain pedestal and soft-close seat.
    • 550mm pedestal waste chute and dektite.
    • 100mm ventilation and drain kit.

    Good to know before purchase

    The CM8 requires approximately 830mm of underfloor clearance. Final pedestal position, tank location, burial depth, ventilation and liquid-management pathway should be confirmed before construction.

    Nature Quick microbes referenced in some historic manufacturer material are not available in New Zealand; the WCTNZ® package uses locally supplied starter materials.
