Outhouse

This complete off-grid toilet package includes a prefabricated wooden outhouse for assembly, a Green Toilet 120 Family batch composting toilet system, a wind-powered Whirlybird ventilator, vent pipes, and all necessary fixtures. It provides a sustainable and odorless toilet solution that requires no water or electricity—perfect for remote cabins, campsites, and various other properties.

The outhouse is delivered as ready-made wooden elements, including the base, walls, door, and roof. It is assembled on-site using standard carpentry tools, requiring only a flat space with a sturdy foundation.

The Outhouse is made of three-layer, PEFC certified Biowood in EU. It features tiny holes shaping a pattern of a heart on the door that brings natural light inside the outhouse. The holes can be covered with a transparent blurred panel for privacy if desired.

The Outhouse has a sturdy design. It does not wobble in any direction. The Outhouse is delivered unpainted for your own creativity.

Inside the Outhouse, there is a small space embedded in the flat seat for organic dry material that can be used to cover the waste from view and improve the quality of the compost. The flat seat surface is made smooth while having a easy to clean and hygienic design.

The roof of the Outhouse is made of corrugated steel sheet.

The Outhouse features a standalone Green Toilet 120 Family batch composting toilet system.

The Outhouse package includes the Green Toilet 120 Family Composting Toilet Package exclusively distributed by Waterless Toilet Shop in North America.

The Green Toilet 120 Family Package is an eco-friendly, waterless composting toilet system made in Finland and designed for family use and small user groups. The system includes a spare composting container, making servicing quick, hygienic, and hassle-free.

How It Works

The Green Toilet 120 Family operates on a batch composting system. Waste is collected in a composting container where it naturally decomposes. The composting container has a double base that separates excess liquid, keeping the compost perfectly moist and odor-free at all times. Once the active container is full, it is swapped with the empty(ied) spare container. The full container is covered and left to compost until the compost is ready for use. This system ensures no direct handling of waste during servicing.

Key features include:

  • Double Base Design: Excess liquids are separated and diverted through a drainage hose to a collection canister. Capillary pillars help maintain the perfect moisture balance, enhancing the composting process.
  • Ventilation System: A ventilation pipe directs airflow from the container out through the roof, preventing odors and improving liquid evaporation.

How It Is Installed

The Green Toilet 120 Family is installed beneath the seat of the Outhouse from behind. The outhouse features wooden rails that guide the Green Toilet container’s waste chute perfectly in place. The liquid drain hose connects to an external container, while the ventilation pipe runs up the back wall of the structure, exiting above the roof to ensure optimal airflow.

Maintenance

  1. Disconnect the full container from the ventilation pipe and liquid drain,
  2. Slide the container out and seal it with the provided closed lid,
  3. Set the full container aside for further composting process,
  4. Replace the full container it with the empty(ied) spare container.

No shoveling or direct contact with raw toilet waste is needed. The entire process takes only about 10-15 minutes.

Works great. We are off grid so we hook it up to a generator/inverter. It takes care of smell and you don’t even hear it.

Life changer.
Been living off grid so you can imagine what that is like when it’s time to go.
I researched it felt like 100’s of toilets and I kept coming back to this one and I am glad I did!
My husband and I were skeptical when we first put it in thinking “ ok, it’s going to be nice to be able to do our business indoors but we will have to figure out what to do for the smell” to our surprise and delight there is absolutely no smell! We bought the upgraded pedestal and from my research that is a big plus and the right ventilation system. I would recommend this product to anyone that lives off grid or any other place that has septic or water challenges

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

Notes & Recommendations:

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
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.

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.
