Tiny-Pod

Composting Toilet

$749.00

Tiny-Pod is a sleek self-contained composting toilet with a swappable bin system (also known as batch composting), tailored for 1–2 individuals and best suited for part-time use. Tiny-Pod has a stylish white look that fits well into modern design. Inside the Tiny-Pod, there is a black solids chamber that separates excess urine from the solid waste, keeping the toilet odorless and optimizing the decomposing process.

With the ability to expand capacity through additional compost bins, the Tiny-Pod is a perfect fit for tiny homes, holiday cottages, and any setting with limited space available for a toilet.

Tiny-Pod

The Tiny-Pod introduces a compact, efficient composting toilet system designed for 1–2 people. The Tiny-Pod works as a swappable bin system (also known as batch composting): it is supplied with two compost bins, so when the bin in use becomes full, it is simply swapped for the empty one and set aside to finish composting. This makes it best suited for part-time or seasonal use; for full-time, year-round use, we recommend expanding the rotation to 2–4 compost bins, or, for continuous heavy-duty use, choosing our larger-capacity Toilet Waste Composter instead. Constructed with durability in mind, it features high resistance to impact, chemicals, and UV light, ensuring longevity and reliability.

Made in Australia.

The Tiny-Pod's attractive design and ease of operation make it an excellent selection for any setting. Its process of aerobic decomposition and evaporation transforms human waste into a clean, safe substance that can be sustainably returned to the earth, ensuring environmental protection.

What is a Self-contained Swappable Bin Toilet?

The Tiny-Pod is a textbook example of a self-contained toilet with a swappable bin system (also known as batch composting).

A self-contained composting toilet is a standalone unit where all solid waste is managed within the toilet itself, although liquids may be diverted and drained out through a hose into a separate container.

The swappable bin system refers to managing waste with multiple bins. Typically, the system includes at least two bins: while one is in active use within the toilet, the other is placed outdoors to undergo further composting. Once the bin in use fills up, it is swapped with the composted bin from outdoors, allowing a continuous cycle of use and composting. This swappable bin method ensures that waste is effectively transformed into compost over time, optimizing space and resource use in environments where sustainable practices are essential.

Key Benefits

Swappable Bin System (also known as batch composting): Tiny-Pod is supplied with two compost bins, both 11.5 gallons. When one bin fills up, the next one can be set into use. The contents of the first bin are expected to be fully composted by the time the second bin has filled up.

Adaptable Capacity: Accommodates 1–2 users with the flexibility to expand by adding more compost bins.

Durable Design: The Tiny-Pod features a durable, elegant, and sturdy construction with high resistance to impact, chemicals, and UV light.

Mess-Free Maintenance: Includes a transit tray (also known as a drip tray) for clean and easy bin exchanges.

Eco-Friendly Process: The composting process effectively reduces waste volume by 70–90%, producing nutrient-rich compost.

Energy-Efficient Operation: Features a low-consumption fan and a system to manage excess liquids efficiently.

Power Options: Supports connection to mains power or an optional 12V solar power for completely off-grid setups.

Simplified Installation: Designed for easy assembly with basic tools, perfect for tiny homes and buildings installed directly on floor level.

Installation

The Tiny-Pod composting toilet is simple to install directly on floor level of your toilet room. To install the Tiny-Pod, you need to make two holes in the back wall of your toilet room: one 3″ hole for the ventilation pipe and another 1″ hole for the excess liquids flowing out from the composting toilet.

For more specific information about the installation of the Tiny-Pod, please refer to the installation and user manual.

Use of the Tiny-Pod

The Tiny-Pod composting toilet is used just like a normal flush toilet, except that it is not flushed. All toilet waste goes into a single compost bin inside the Tiny-Pod. Toilet paper can also be put into the toilet, as it composts along with the other solids inside the bin. However, please note that any items containing plastic, e.g., sanitary towels, should be placed into a separate trash bin as they do not compost.

Tiny-Pod composting toilet

Following each use, it is advised to sprinkle a cup of covering material, like hemp or peat, over the waste through the toilet seat to aid the composting process and to cover tracks of use.

Service of the Tiny-Pod

Tiny-Pod Service in 15 seconds

The average length of time until a bin is 80 percent full (recommended exchange level) is around 4–6 weeks with 2 people in full-time use.

When it is time to exchange or empty the Tiny-Pod, the top of the system is first removed. Then, a lid is put onto the compost bin either while it is still inside the unit or outside. The lid is secured to the bin with bungee loops, and the bin is lifted onto a drip tray (also known as a transit tray) next to the Tiny-Pod. The tray’s purpose is to prevent excess liquids from dripping onto the floor while the bin is carried out for emptying, and it is fastened to the bin with another set of bungee loops. The full compost bin is now ready to be carried outside for further composting or emptying. As in any swappable bin system (also known as batch composting), the waste will finish composting in this bin while the second bin is in use.

Tiny-Pod compost bin

By the time the second bin has filled up, the contents of the first bin should be ready to be used as a fertilizer in, e.g., a garden, or disposed of appropriately. Should the first bin not be ready yet by the time the second bin has filled up, we recommend either purchasing an extra compost bin or a larger, completely separate toilet waste composter with greater capacity.

Please note that there is no definite way to determine if the composting process has finished fully. A good rule of thumb is that if the compost looks and feels ready and does not smell, then it most likely is ready.

  • Tiny-Pod composting toilet
  • 2 compost bins (11.5-gallon capacity each)
  • 1 lid & 1 transit tray (also known as a drip tray) as standard
  • 2 x Jute liners
  • 12V fan & housing, mains transformer and plug
  • Vent cowl
  • Moisture trap to protect the fan from condensation
  • Covering material
  • 65mm pipe & excess liquids drainage pipe

This is everything you need to set the system up and get going, except the 4″ vent pipe and slotted drainage pipe (not included for transport reasons and affordably obtainable from any local hardware store).

Optional accessories

*Recommended for off-grid installations without electricity. Use the coupon code “DROP FAN” at checkout to remove the electric fan from the basic package and receive a discount for its exclusion.

**We recommend considering the purchase of a replacement fan along with your toilet, so you’ll have one on hand in case the original fan eventually needs replacing after year(s) of use.

Does the Tiny-Pod smell?

No — set up correctly, it smells less than the flush toilet you’re used to. The black solids chamber separates excess liquid from the solid waste, keeping it dry enough to compost properly, while the fan draws air continuously out and away. 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.

Is the Tiny-Pod suitable for full-time, year-round use?

The Tiny-Pod is best suited for part-time or seasonal use with its standard two bins. For full-time, year-round use, we recommend expanding the rotation to 2–4 compost bins, or, for continuous heavy-duty use, choosing our larger-capacity Toilet Waste Composter instead.

Is it comfortable for family and guests to use?

Yes. It looks and operates like a regular flush toilet, so there’s no awkward technique for kids, older relatives, or guests to learn.

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 compost bin gives you the buffer capacity to cover it.

Where is the Tiny-Pod made?

The Tiny-Pod is designed and manufactured in Australia by our partner Green Loo — the same team behind the Oz-e-Pod.

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

The Tiny-Pod runs on a low-power and quiet 12V fan, light enough to run off the optional 12V solar setup for a fully off-grid installation.

Ohio Weekend Off Gridder

Rookie Off Gridder & Tiny Pod. I have an off grid cabin in southern Ohio. I wanted something I could install and use without having to deal with poo on a regular basis. The Tiny Pod fits my needs well. Eemeli was super helpful in answering my questions and the boxes came with most of the supplies I needed. I did need to buy some perforated pipe, some hole saws and some pipe glue for my customized unit. I also needed to raise up the pod on to a platform I made so that the urine drain pipe would go over the bottom plate of my wall and also ro help get some downward slope for the urine drainage. Overall, I’m pleased so far. I’m pretty skilled at do it yourself work so it was a fun project for me once I had everything planned and figured out.

This pipe package worked great. We had to get a few extra pieces just because we needed to extend it to the side of the house that the snow doesn't fall off of.

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
365 days (1 year) ~0.5 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.

🟢 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.
