Oz-e-Pod

The Oz-e-Pod is an advanced, self-contained composting toilet that works as a swappable bin system (also known as batch composting), designed for the sustainable lifestyle of 1–2 individuals full-time or 2–3 individuals part-time. The standard delivery package includes two special composting bins: when the bin in use becomes full, it is simply swapped for the empty one, and the full bin composts under its closed lid. The capacity is also easy to expand with additional compost bins if needed. The Oz-e-Pod is made of ASA material that is durable and withstands impacts, chemicals, and UV exposure, ensuring longevity and reliability.

Made in Australia.

Key Benefits

  • Forget Flushing: The Oz-e-Pod, like all our waterless toilets, does not require any water to flush the waste.
  • Familiar Design: Looks and feels like a regular flush toilet.
  • Adjustable Capacity: Suitable for 1–2 full-time or 2–3 part-time users, with the option to expand by adding extra compost bins.
  • Durable Construction: Made of ASA for superior resistance to impact, chemicals, and UV light.
  • No Mess, No Fuss: Features a 'transit tray' for clean bin exchanges.
  • Privacy Guaranteed: A chamber screen conceals compost when not in use.
  • Waste Reduction: Efficiently reduces waste volume by 70–90%, producing nutrient-rich, safe compost.
  • Energy Efficient: Includes a low consumption fan and an effective drainage system for liquid waste.
  • Simplified Installation: Designed for easy set-up with basic tools, ideal for tiny homes and cabins. Does not require any clear space below the bathroom floor (unlike split-system composting toilets).

Use of Oz-e-Pod

The Oz-e-Pod composting toilet is used similarly to a traditional flush toilet, with the exception that it is not flushed. All waste, including toilet paper, is deposited into a single compost bin within the Oz-e-Pod, where it composts into humus and mulch. However, it’s important to remember that items containing plastic, such as sanitary towels, must be disposed of in a separate waste bin since they are not suitable for composting.

One of the neat features of the Oz-e-Pod is the view screen. The view screen conceals the waste from direct view above. The view screen is operated by hand before and after each use of the toilet.

oz-e-pod view screen

After every solid deposit, it is recommended to scatter a cup of covering material, such as hemp shavings or peat, over the waste via the toilet seat. This practice improves the quality of the compost. When placing an order for a new Oz-e-Pod composting toilet, do not forget to take advantage of shipping and add some extra hemp covering material into your order.

Installation of the Oz-e-Pod

The Oz-e-Pod composting toilet is designed for easy installation directly on the bathroom floor, requiring an area of approximately 26 x 20 inches (please refer to the other tab for precise dimensions).

The vent pipe installation

This toilet features a ventilation pipe located at the back, which needs to be routed outside the bathroom. Typically, this involves drilling a hole through the back wall of the bathroom to accommodate the 3-inch vent pipe.

If drilling through the back wall is not feasible, you have the option to reroute the ventilation pipe to the side of the Oz-e-Pod. To do this, you would need to drill a new vent hole on the desired side and seal the pre-existing rear vent outlet.

The liquid drainage pipe installation

The Oz-e-Pod composting toilet separates excess liquid from the solids within the black composting bin. The excess liquid (= liquid that has not been absorbed into the solid compost mass) drains out from the back of the Oz-e-Pod through a flexible drainage pipe.

When installing the Oz-e-Pod, you need to make a hole for the drainage pipe through your bathroom wall or floor so that liquid flows out naturally.

The liquid waste can be collected for example into a jerry can or filtered through non-edible plants and trees that can use the nutrients in the liquid. Please make sure to check your local regulations regarding the use of compost and liquid waste from the composting toilet.

Service of Oz-e-Pod

The Oz-e-Pod is serviced by a standard procedure involving carrying the inner composting bin out of the house and replacing it with an empty spare bin. This is the swappable bin system (also known as batch composting) in action: the full bin is sealed with the closed lid and set aside to continue composting, while the empty bin takes its place in use. By the time the second bin fills up, the compost in the first one is ready.

Does the Oz-e-Pod smell?

No — set up correctly, an Oz-e-Pod smells less than the flush toilet you’re used to. The composting bin’s design separates excess liquid from the solid waste through small holes at the bottom, keeping the solids dry enough to compost properly, while the fan draws air continuously out and away. As with any waterless toilet, the few things that can cause odor — a switched-off fan, a blocked vent, or a blocked liquid hose — are easily avoided and easily fixed.

Can I use it indoors, or only in an outbuilding?

Both. The Oz-e-Pod is fully self-contained and sits directly on the bathroom floor — no space below the floor is needed — which makes it just as suitable for an indoor bathroom, ADU, or tiny home as it is for a cabin or outhouse.

Is it comfortable for family and guests to use?

Yes. The Oz-e-Pod looks and feels like a regular flush toilet, so there’s no awkward technique for kids, older relatives, or guests to learn — it’s one of the reasons it’s a popular choice for cabins the whole family actually wants to visit.

Do I need the second compost bin, or can I add more later?

The standard package already includes two bins, which is what makes it a swappable bin system from day one. If your household grows or you move to full-time use, you can add a third (or more) compost bin at any time — each additional bin extends the comfortable capacity by roughly one more person’s worth of part-time use.

Can I use it in a cold climate? What happens if it freezes?

Yes. Freezing temperatures pause the composting process but don’t stop you from using the toilet — composting simply resumes once temperatures rise again. In very cold regions with a short composting season, an extra spare bin gives you the buffer capacity to cover it.

Is the Oz-e-Pod NSF certified? Do I need a permit?

None of our composting toilets — including the Oz-e-Pod — currently hold NSF 41 certification; the certification process is long and expensive. The Oz-e-Pod has instead been independently tested and certified in Australia to AS/NZS 1546.2:2008 (download certificate), which covers the same core requirements as NSF 41. Whether you need a permit depends entirely on your state and county — read our full answers: Are waterless toilets NSF certified? and Do I need a permit to install a waterless toilet?

How much power does the fan use — is it loud?

The included 12V DC fan is low-power and quiet enough that most owners stop noticing it’s running. It’s light enough to power from the Solar Power Bank Kit for a fully off-grid setup.

Oz-e-pod in a modern bathroom familiar design

Familiar design

The Oz-e-Pod is a popular choice among many tiny house and cabin owners as it looks and feels a lot like a regular flush toilet. The system is robust: one cannot break the toilet simply by using it. Nor do you have to worry about hitting the right bowl when using the toilet (compare to urine-diverting toilets). All waste (incl. toilet paper) falls into the same composting bin where liquid is separated.

oz-e-pod view screen

View Screen

One of the standout features of the Oz-e-Pod is its view screen, which discreetly conceals waste from direct sight. The view screen is manually operated before and after each use, ensuring a clean and pleasant experience for you and the next toilet user.

Oz-e-pod bottom separation

Separation of excess liquid

The Oz-e-Pod separates excess liquid from the solid waste through tiny holes at the bottom of each black composting bin. The separation of liquid ensures that the toilet remains odorless at all times and is therefore pleasant to use. The separation of liquid is also important for the natural composting process because this feature keeps the solid compost mass ideally moist: not too wet, not too dry.

The excess liquid is drained out from the Oz-e-Pod composting toilet through a flexible drainage pipe supplied with the package.

Oz-e-pod batch composting toilet has extendable capacity with spare composting containers

Scalable capacity

The Oz-e-Pod composting toilet is ideal for 1–2 full-time users or 2–3 part-time users. If needed, the toilet’s capacity can be easily expanded by adding extra composting bins. The standard package includes two composting bins.

recommended accessories for off-grid installation

No Electricity? No Problem!

If electricity is not available, we recommend our Solar Power Bank Kit and Whirlybird as accessories for your off-grid composting toilet system. The Oz-e-Pod composting toilet is equipped with a 12 V DC ventilation fan (AC adapter included), which can be powered by the Solar Power Bank Kit for up to 24 hours without sunlight. In addition, the wind-driven Whirlybird ventilator provides effective ventilation on cloudy/windy days.

Great toilet I have some property off the grid. I needed waterless toilet, and I couldn't have picked a better one! It was easy to set up, easy to use, and doesn't smell. Even my very high maintenance kids are excited to use it!

We live in Downeast Maine, and so far, I have been very happy with the setup! Our house was built on a pile foundation on a ledge, and it would cost more than usual to install a septic system, so we looked into other options. We had just enough room under the house for this size bin. (Note: we bolted the pressure treated boards to the ledge.) Also, I recommend getting the extra solar fan vent cover.
I will update my review after this winter as well.

Green Toilet Compact Lux

Average Daily Capacity per 26-Gallon Composting Bin

(Based on approx. 150 uses involving a #2 — i.e., poop) – only the solids count!

Service Interval #2 Visits per Day (involving a #2)
30 days (1 month) ~5.0 visits/day
60 days (2 months) ~2.5 visits/day
90 days (3 months) ~1.7 visits/day
180 days (6 months) ~0.8 visits/day
365 days (1 year) ~0.4 visits/day

👥 Roughly how often will I service a bin?

Full-Time Users Time Before a Bin Swap
1 person about 4–5 months
2 people about 2–3 months
3 people about 1.5–2 months
4 people about 1–2 months

🟢 What counts as a “#2 visit”?

Only visits that involve pooping (i.e., going number two) — urine-only visits don’t contribute to filling the composting bin and are not included in the estimate.

🔄 Why two bins?

The Green Toilet Compact Lux comes with two composting bins. The figures above are per bin: when one fills up you swap in the empty one, and the full bin is left to compost undisturbed until you next need it. The second bin doesn’t make the interval longer — it means you never have to empty a bin in a hurry. Additional bins can be added at any time.

⚠️ Disclaimer: These estimates are approximations. The actual number of solid uses per bin may vary significantly depending on climate, temperature, ventilation, user habits, and the amount of dry bulking material (e.g., wood shavings or peat) added after each use.

CF 8 Composting Toilet – Estimated Daily Capacity

The CF 8 is a continuous composting toilet system featuring a single large 250-gallon container. Like the CF 4, it is designed for gradual emptying rather than batch-style use. Solids are typically removed in thirds or sections, allowing earlier deposits time to fully compost inside the tank.

This setup allows for either:


🔁 Continuous Use: Gradual Emptying in Thirds

When used year-round, the CF 8 is typically emptied one-third at a time, effectively composting in three rotating “piles” within the container.

Because the CF 8 is more than twice as large as the CF 4, each pile can hold approximately 480–960 poops, depending on composting conditions and how much bulking material is used.

Service Interval (per pile) Estimated #2 Visits per Day
30 days (1 month) ~17–32 visits/day
60 days (2 months) ~8–16 visits/day
90 days (3 months) ~5–11 visits/day
180 days (6 months) ~3–5 visits/day
365 days (1 year) ~1.2–2.6 visits/day

💡 These figures assume that one-third of the tank is in active use at a time, with older waste given time to compost before removal.


🌤 Seasonal Use: Full-Tank Emptying After Inactive Period

For cabins, cottages, or other sites used seasonally, the CF 8 can be used for a few months and then left idle to allow full composting. In such cases, the entire tank may be emptied once a year.

Full-tank capacity estimate: ~1,440–2,880 poops

Example: 120 days of use (approx. 4 months):
→ ~12–24 solid visits per day on average


⚠️ Disclaimer

These numbers are rough estimates based on typical use and conditions. Actual capacity will vary depending on:

For best performance, ensure proper aeration, regular bulking material use, and consistent emptying of composted portions.


💡 Want to Maximize Capacity? Consider a Urine-Diverting Toilet — With Some Important Considerations

upgrade to a urine diverting toilet pedestal

If you’re looking to maximize the capacity of the CF 8 system — aiming for 960+ poops per composting “pile” — we recommend using a urine-diverting (UD) toilet pedestal.

✅ Benefits of Urine Separation:

By diverting urine out of the solids container, the volume taken up by absorbent material (like peat or wood shavings) is significantly reduced. This can make a big difference in how often the system needs to be emptied.


⚠️ Downsides to Consider:

Urine-diverting toilets can take some time to get used to. Users need to sit or aim correctly to ensure proper separation, which might not happen consistently without experience or guidance.

For this reason, UD toilets are generally not ideal for public or commercial settings where the toilet is used by guests, tourists, or other first-time users. In these cases, misuse can reduce the effectiveness of the system and may even lead to unpleasant maintenance issues.


In short: A UD toilet is an excellent choice for maximizing capacity in private or family use, but for guest or public access composting toilets, a standard non-diverting model may be more practical and user-friendly.

Green Toilet 100 Easy – Estimated Daily Capacity

The Green Toilet 100 Easy is a compact and user-friendly batch composting toilet with a 26-gallon composting container. Its design makes it well-suited for outhouses, cabins, and even indoor use. A spare container is available to expand capacity and simplify servicing.


🔢 Estimated Solid-Waste Capacity per Bin:

Note: Due to the shape and internal structure of the container, the actual composting capacity is slightly lower than its raw volume might suggest, if you compare with Green Toilet 120 Family composting toilet for example.


📆 Average Daily Capacity per Bin

Service Interval Estimated #2 Visits per Day
30 days (1 month) ~6–7 visits/day
60 days (2 months) ~3–4 visits/day
90 days (3 months) ~2.2 visits/day
180 days (6 months) ~1.1 visits/day

CF 4 Composting Toilet – Estimated Daily Capacity

The CF 4 is a continuous composting toilet system featuring a single large 105-gallon container. Unlike batch composting systems (such as the Green Toilet models), the CF 4 is designed for gradual emptying — solids are typically removed in thirds or sections, allowing earlier deposits time to fully compost inside the tank.

This setup allows for either:


🔁 Continuous Use: Gradual Emptying in Thirds

When used year-round, the CF 4 is typically emptied one-third at a time, effectively composting in three rotating “piles” within the container. Depending on composting conditions and how much bulking material is used, each pile can hold approximately 200–400 poops.

Service Interval (per pile) Estimated #2 Visits per Day
30 days (1 month) ~7–13 visits/day
60 days (2 months) ~3–7 visits/day
90 days (3 months) ~2–4 visits/day
180 days (6 months) ~1–2 visits/day
365 days (1 year) ~0.5–1.1 visits/day

💡 These figures assume that one third of the tank is in active use at a time, with older waste given time to compost before removal.


🌤 Seasonal Use: Full-Tank Emptying After Inactive Period

For cabins, cottages, or other sites used seasonally, the CF 4 can be used for a few months and then left idle to allow full composting. In such cases, the entire tank may be emptied once a year.

If you’re looking to maximize the capacity of the CF 4 system — aiming for 400+ poops per composting “pile” — we recommend using a urine-diverting (UD) toilet pedestal.

✅ Benefits of Urine Separation:

By diverting urine out of the solids container, the volume taken up by absorbent material (like peat or wood shavings) is significantly reduced. This can make a noticeable difference in how often the system needs to be emptied.

⚠️ Downsides to Consider:


In short: A UD toilet is an excellent choice for maximizing capacity in private or family use, but for guest or public access composting toilets, a standard non-diverting model may be more practical and user-friendly.

Green Toilet 120 Family

💩 Average Daily Capacity per 31-Gallon Composting Bin

(Based on approx. 356 uses involving a #2 — i.e., poop) – only the solids count!

Service Interval #2 Visits per Day (involving a #2)
30 days (1 month) ~11.9 visits/day
60 days (2 months) ~5.9 visits/day
90 days (3 months) ~4.0 visits/day
180 days (6 months) ~2.0 visits/day
365 days (1 year) ~1.0 visits/day

🟢 What counts as a “#2 visit”?
Only visits that involve pooping (i.e., going number two) — urine-only visits don’t contribute to filling the composting bin and are not included in the estimate.

⚠️ Disclaimer:
These estimates are approximations. The actual number of solid uses per bin may vary significantly depending on climate, temperature, ventilation, user habits, and the amount of dry bulking material (e.g., wood shavings or peat) added after each use.

Green Toilet 330

💩 Average Daily Capacity per 87-Gallon Composting Bin

(Based on approx. 1,000 uses involving a #2 — i.e., poop) – only the solids count!

Service Interval #2 Visits per Day (involving pooping)
30 days (1 month) ~33 visits/day
60 days (2 months) ~17 visits/day
90 days (3 months) ~11 visits/day
180 days (6 months) ~5.6 visits/day
365 days (1 year) ~2.7 visits/day

🟢 What counts as a “#2 visit”?
Only visits that involve defecation (pooping) — urine-only visits don’t fill up the composting bin and are not included in the 1,000-use estimate.

⚠️ Disclaimer:
These estimates are based on typical, steady use. The actual number of solid uses a composting bin can handle may vary significantly depending on climate, temperature, humidity, ventilation, and how much dry bulking material (like wood shavings) is added after each use.
