Tiny-Pod

The Tiny-Pod introduces a compact, efficient composting toilet system designed for 1-2 people, ideal for both full-time and part-time use. The capacity of the Tiny-Pod can be easily enhanced with the addition of optional extra compost bins, making it a scalable solution for waste management. Constructed with durability in mind, it features high resistance to impact, chemicals, and UV light, ensuring longevity and reliability.

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 Batch Composting Toilet?

The Tiny-Pod is a textbook example of self-contained batch composting toilets.

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

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

Key Benefits

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 bin is expected to be fully composted by the time the second container has filled up.

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

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

Mess-Free Maintenance: Includes a ‘transit tray’ for clean and easy container exchanges.

Eco-Friendly Process: 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. To install the Tiny-Pod you need to make two holes to the back wall of your toilet: 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

Tiny-Pod composting toilet is used just as a normal flush toilet, except that it is not flushed. All toilet waste goes into single compost bin inside the Tiny-Pod. Toilet papers can also be put into the toilet as they compost along 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.

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 container is 80 percent full (recommended exchange level) is around 4 – 6 weeks at 2 people 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 still inside the unit or outside. The lid is secured with bungee loops to the container and lifted onto a drip tray next to the Tiny-Pod. The purpose of the drip tray is to prevent excess liquids dripping onto the floor while carried to for emptying. The drip tray is fastened to the compost bin with another set of bungee loops. The full compost bin is now ready to be carried outside for further composting / emptying. The waste will finish composting in this container while the second container is in use.

Tiny-Pod compost bin

By the time the second container has filled up, the first container should be ready to be reused as a fertilizer in e.g. a garden or disposed appropriately. Should the first container not be ready yet by the time the second container has filled up, we recommend either purchasing an extra spare bin or a greater completely separate toilet waste composter with larger 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, does not smell, then it most likely is ready.

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.

Arrived quick! The seat itself (not the pedestal which seems the more likely) was cracked on arrival. It was a bummer but the customer service is on point, sent not one but TWO replacements because the first redo was cracked too! Crazy. Anyway.. Gorgeous throne, 5/5 will poop again.

I recently installed a family 120. Works well so far. I was planning a split system that I didn't think was manufactured and found this shop and it fit perfectly! Hallelujah! Saved me a bunch of time. I added an extra air tube in the corners from a section of drain pipe with the holes to help keep the compost aerobic.

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

These estimates are intended as general guidance. Real-world performance may vary depending on:

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
