Why it is built this way

Five things that make it a real outhouse.

01

Solid wood, not sheet cladding on a light frame.

Walls, roof and interior are ¾ in (20 mm) solid Finnish spruce all the way through. It is the biggest difference you can feel with your hand.

02

The outhouse and the toilet are designed for each other.

The bench seat, the opening at the back and the height all exist because of the Green Toilet 330. The Finnish Outhouse is pleasant to use and easy to service.

03

Real ease. Swap, don't shovel.

The Green Toilet system was first designed in Finland in the early 1990s. When a container is full, it rolls out through the opening at the back on its own wheels. You close it with its lid and set it aside to finish composting, and the empty spare goes in.

No smell inside.

Liquid separation and steady ventilation keep the Green Toilet 330 odor-free, so the outhouse is pleasant to use. Guests need no instructions: they use it like any toilet.

Why the Finnish Outhouse

Nicer on day one. Much nicer on day 1,000.

Most outhouses are one of three things: a shack over a pit or concrete vault, a plastic portable toilet, or something you build yourself. Each comes with a catch: the hole in the ground, the pump truck, or the weekends it takes. The Finnish Outhouse is solid Finnish wood around a toilet you swap instead of pump, odor-free by design, with a proper bench and windows to the outside. A place people actually like to go, year after year.

For campgrounds, parks and rentals

From one to as many as you need.

A family cabin is the natural home for a Finnish Outhouse. And it scales without fuss to a business or a public site, not only by adding outhouses but, above all, by adding Green Toilet containers. Every extra container is more capacity, so a single outhouse can serve many more people. When one is full you swap in the next, and the full ones keep composting until you are ready to empty them.

Not sure an outhouse is the right fit?

Indoors or out, a few people or many: answer a few questions and we will show the toilets that fit.

Questions

What buyers ask first.

How is it different from a traditional outhouse?

A traditional outhouse sits over a pit, so waste collects in the ground and the smell rises through the seat. The Finnish Outhouse stands on a base above the ground with the Green Toilet 330 inside. Waste goes into a container that you roll out, close and set aside to compost, and a vent draws the air out above the roof. There is no pit to dig.

Will it smell?

No. The toilet is ventilated through a 4 in pipe and a Whirlybird ventilator, so the outhouse stays odor-free when it is used as the manual says.

Will it last outside?

Yes. The outhouse is ¾ in (20 mm) solid wood on a pressure-treated base, designed and made in Finland.

How hard is it to put up?

It arrives flat-packed as finished wall, roof and floor elements on a pallet. Two people with standard hand tools put it together on flat, compacted ground. Assembly usually takes 2–4 hours. No concrete, no plumbing, no wiring.

How often do I empty it?

It depends on how many people use it. When a container is full, swap it for the empty one and set the full one aside to compost. No tools needed. Extra containers can be added at any time.

What does it cost?

$6,490 for the complete set. Freight is quoted separately to your ZIP code and usually runs $400–800, depending on where it ships.

How soon can I have it?

The Finnish Outhouse is on pre-order now. The first sets ship from mid-January 2027, and delivery takes about 1–2 weeks from shipping. The set ships flat-packed on a pallet, by truck freight to your address.

Notes

  1. Set-up time. The outhouse arrives as finished wall, roof and floor elements on a pallet, and the base is a kit. Two people with standard hand tools can usually put it together in 2–4 hours. The time depends on your experience and your site, and it does not include preparing the ground or painting or staining the wood. ↩
  2. Where it stands. The base needs level, compacted ground, for example a gravel bed. It is pressure-treated Finnish pine and lifts the outhouse off the ground, out of standing water and snow. ↩
  3. Time between swaps. Each container holds 87 gal (330 L). How long one lasts depends on how many people use the toilet and how often, so a cabin or part-time home can go up to a year before a container is full, and heavier use fills it sooner. When one container is full you swap it for the spare, and the full one keeps composting. Additional spare containers are available separately for increased capacity. ↩
  4. Odor-free. The toilet is ventilated: a 4 in vent pipe leads from the toilet up above the roof, and the Whirlybird wind ventilator draws air through it without power. It stays odor-free when it is installed and used according to the manual included. ↩
  5. What the price covers. The price is for the complete set listed above: the outhouse, the base and steps, the Green Toilet 330 with its spare container, the Whirlybird ventilator and vent pipe, the fixings and the manuals. It does not include freight, which is quoted to your ZIP code, nor paint or stain. The wood should be painted or stained as soon as the outhouse is up. ↩

No Black Friday games

We don’t run Black Friday sales. We’d rather price our toilets fairly all year than mark them up in the fall and “discount” them in November.

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

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.
