Urine-diverting toilet

$749.00

The Green Toilet Light is a versatile, urine-diverting waterless toilet for both indoor and outdoor use. Featuring a soft thermal seat, it ensures comfort even in colder environments. The Green Toilet Light is straightforward to install directly on floor.

The Green Toilet Light is durable with a simple, robust structure free of easily breakable moving parts. The Green Toilet Light is totally odorless and very pleasant to use even in non-heated space.

The Light is ideal for everyday use of 1-2 persons, but it is also often used as the alternative toilet indoors whenever it is inconvenient to go to the outhouse for example during nighttime or bad weather.

Green Toilet Light

The Green Toilet Light is a urine diverting toilet suitable for various settings. Typically the Light is used as an alternative toilet inside an off-grid cabin, outhouse or some other shed-like structure.

The GT Light separates urine from solids directly in the toilet. When using the toilet, urine naturally directs to the front bowl while solids go the rear chamber. The separation of urine ensures the toilet stays odor-free at all times.

Because of urine-separation, the Green Toilet Light is ideal for family use where everyone knows how to use the toilet. The Green Toilet Light is suitable for both outdoor outhouses and indoor settings. It features a comfortable thermal seat, ensuring warmth and comfort even in very cold conditions. For indoor installations, it's advisable to use an electric duct fan, available separately. If there is no power to run electric fan, we recommend looking into our Whirlybird and Solar Panel fans.

The Green Toilet Light is used pretty much like any regular toilet, except that the toilet is not flushed when you are done. Because of urine-separation, the toilet has to be always used seated. This ensures that urine is directed into the front bowl, and solids, along with toilet paper, go into the rear chamber. While adding dry bulking material into the solids chamber is not required, it’s an option if desired.

Green Toilet Light Urine-separating design

Note! There is a waterless urinal available for men who prefer to pee standing.

The Green Toilet Light is simple to maintain. The toilet has a detachable back wall to access the solids container. The container has a lid and handles so that it can be carried to emptying.

Generally, the solid waste can be composted in a larger composter outdoors at yard. If you are unsure, please consult your local authorities at the department of environmental quality for appropriate disposal of waste.

Can the Green Toilet Light be used in colder environments?

Absolutely. The Green Toilet Light comes with a thermal seat that remains warm, offering a comfortable experience even in chillier settings such as cold outhouses or rooms. Just ensure that the urine hose is positioned to flow downwards to prevent freezing and blockage.

How is the Green Toilet Light installed?

For outhouse installations, simply cut a hole in the back wall and slide the Green Toilet Light into position.

The unit features pre-marked areas for liquid hose and ventilation pipe installation on both sides, allowing you to choose the best side based on your setup requirements.

For indoor setups, there’s no need to cut through your home’s wall. Maintenance can be performed by moving the Green Toilet Light from its location.

How should I manage the solid waste?

We advise composting the solid waste in a lidded composter along with other garden waste. The ideal composting duration ranges from 6 to 18 months, varying by climate and conditions.

What should I do with the urine?

Sterile urine is very nutrient-rich and therefore it should not be disposed of in any waterways or concentrated in a single area. We suggest collecting urine in a canister, diluting with water, and using it to fertilize trees, bushes, and plants, thereby utilizing its nutritional value.

Can urine be collected inside the toilet?

No, the design of the Green Toilet Light does not allow urine to be collected inside the toilet. Instead, urine must be drained out. The Green Toilet Light includes two pre-cut openings at the back for a urine hose, but you can also drill a hole at any height or side to accommodate your preferred setup.

If you’re looking for a urine-diverting toilet that collects both solid and liquid waste inside the unit, check out our RV-Pod Urine-diverting toilet.

Here at Tranquility Grange in Lincolnville Center, Maine, we were pleased at the promptness of delivery. Our guys quickly installed the Green Toilet, built a bench for it, and installed the container at the lower level of the building with a door to the exterior. We are now looking forward to extending our use of the Grange Hall into the cold weather after the pipes are drained.

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.

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

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.

🟢 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.
