Rob
Dug a 3 foot hole and filled it with lava rocks then pavered over it.
Looks and works great!!
Thank you
I put it in my shop bathroom, well it just makes it smell like piss in there if I don’t follow with a bucket of water to flush it. I could have just used the same amount of water by pissing in the toilet and flushing less often. How about an option to be able to actually flush this with water, and valve.

I put it in my shop bathroom, well it just makes it smell like piss in there if I don't follow with a bucket of water to flush it. I could have just used the same amount of water by pissing in the toilet and flushing less often. How about an option to be able to actually flush this with water, and valve.
My son and I own a wooded piece of property in northern Michigan with a travel trailer. We wanted to avoid constantly taking the trailer to a dumping station when the black water tank got full, so we decided to build a small outbuilding for a composting toilet.
After searching online for a solution that would suit our needs, we found the Waterless Toilet. The price, engineering, and comprehensive instructions were exactly what we were looking for.
We followed the instructions and installed the toilet in our outbuilding. The porcelain toilet is a great feature—it looks very clean and professional. The height and seat are comfortable, it is very easy to use, and there is absolutely no odor. We are completely satisfied with our purchase.

🟢 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:
Year-round use with gradual emptying, or
Seasonal use (e.g., 4–5 months/year) with full emptying once per year
🔁 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:
Climate (temperature and humidity)
Ventilation and air flow
How much dry bulking material is added
User behavior and emptying practices
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
If you’re looking to maximize the capacity of the CF 8 system — aiming for 960+ poops per composting “pile” — we recommend using aurine-diverting (UD) toilet pedestal.
✅ Benefits of Urine Separation:
Reduces or eliminates the need for dry bulking material, which frees up valuable space in the composting unit
Helps keep the compost drier, more aerated, and better suited for natural decomposition
Increases the total capacity of the composting container
Can lead to faster and more efficient composting, especially in high-use environments
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 Easyis 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 containeris available to expand capacity and simplify servicing.
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:
For seasonal or weekend use, one container often lasts a full summer.
For more frequent use, we recommend the package with a spare container. This allows one bin to rest and compost while the other is in active use.
Don’t forget to add dry bulking material (like wood shavings or peat) regularly to maintain airflow and prevent odors.
⚠️ Disclaimer: These estimates are intended as general guidance. Real-world performance may vary depending on:
Climate and temperature
Ventilation quality
How much dry bulking material is used
Number of users and usage patterns
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:
Year-round use with gradual emptying, or
Seasonal use (e.g. 4–5 months/year) with full emptying once per year
🔁 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)

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.
Full-tank capacity estimate: ~600–1,200 poops
Example: 120 days of use (approx. 4 months): → ~5–10 solid visits per day on average

💧 Liquid waste (urine) estimate
Average person produces about:
0.4 gallons of urine per day (≈1.5 liters ≈ 1.6 quarts)
So for 100 people:
0.4 gallons × 100 = 40 gallons of urine per day
🚽 Flush water use estimate
Average flush volume in the U.S. is about:
1.5 gallons per flush
Average person flushes ~5 times per day, so:
1.5 gallons × 5 = 7.5 gallons/person/day
So for 100 people:
7.5 gallons × 100 = 750 gallons of flush water per day
