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.

A real porcelain toilet in your bathroom, with a large composting bin out of sight below the floor. The Lux 330 needs at least 37″ of clear space under the floor – it takes room, but in return you get one of the largest capacities we offer. No water, no plumbing, no septic. Two 87-gallon bins on wheels come in the box, and two adults living there full time typically swap a bin only about once a year. That long service interval is why it’s one of our most popular models.

About the Green Toilet Lux 330
Made for homes, cabins, vacation rentals and public restrooms with room under the floor.
- Looks and works like a regular toilet – real porcelain, nothing to flush, no instructions needed for guests.
- One of the longest service intervals we offer – two adults full time typically swap a bin only about once a year.
- Serviced outside the bathroom – the bins are on wheels, and there's no shoveling.
- Odor-free when set up right – the fan vents the bin, not your bathroom.
- Works off-grid – no water, and the small 12V fan runs on our Solar Power Kit, or vent with a wind-driven Whirlybird.
- Built to last – made in Finland, in use since the early 1990s, with hardly any moving parts to break.
How it works. Waste drops through an 8″ pipe into an 87-gallon bin below the floor. Much of the liquid is used up in composting and evaporates through the vent*; a double base drains the rest to a 5-gallon canister. The fan draws air and odors out of the bin and up the vent pipe. The bin takes its fresh air through its own small inlet from the space it sits in, not from your bathroom, so in a cold-climate home it won't pull warm air out of the room.
Emptying is a swap, not a shovel job. When a bin is full, wheel it out, close the lid and set it aside to finish composting, then wheel the empty one in. A completely full bin is heavy, so many owners swap a little early.
Who it suits: comfortably 1–8 people full time or 1–12 part time with the two bins in the box. More people simply means swapping more often – or adding spare containers, which makes capacity practically unlimited, even for busy public sites.
Less room under the floor? With 28″, the Lux 120 gives you the same porcelain toilet; with 18″, the GL 90. No crawl space at all? See our floor-standing toilets.
*How much evaporates depends a lot on use and climate. More about liquid →
The Green Toilet is a certified product Manufactured to: AS/NZS 1546.2:2008 - On-site domestic wastewater treatment units – Waterless composting toilets.
Option: Upgrade to Urine-Separating Porcelain Pedestal
By default, all our premium waterless toilets, including the Green Toilet Lux 330, come with a high-quality non-separating porcelain pedestal. For those who prefer, we offer the option to upgrade to a urine-diverting porcelain pedestal. This design separates urine from solids at the the toilet seat, reducing odors and need for additional dry cover materials.
No Electricity? No Problem!
If electricity is not available, we recommend our Solar Power Bank Kit and Whirlybird as accessories for your off-grid composting toilet system. The Green Toilet Lux composting toilet is equipped with a 12 V DC ventilation fan (AC adapter included), which can be powered by the Solar Power Bank Kit for up to 24 hours without sunlight. In addition, the wind-driven Whirlybird ventilator provides effective ventilation on cloudy/windy days.
How it is used
Use of the Green Toilet Lux 330
Using it feels just like home: sit down, close the lid when you’re done – the only thing missing is the flush. Waste and toilet paper drop through the pipe into the dark bin below, so there’s usually nothing to see from the seat. Family, guests and renters can use it right away – no instructions or training needed.
After a #2, sprinkle about a coffee mug of dry material through the seat – the hemp included in the box works great. After peeing, nothing at all. Prefer less routine? Many owners simply add a bigger scoop, about 1–2 gallons, once or twice a week. No need to overdo it – extra material just fills the bin faster. And if a guest forgets, no harm done.
The only rule: no wipes, pads, diapers or other plastics – a small trash can next to the toilet takes care of those.
Easy to keep clean: the smooth porcelain bowl often stays clean by itself. When it needs a refresh, for example once a week, a little water, a toilet brush and a biodegradable cleaner are all it takes. Skip regular toilet cleaners and chemicals – the composting works best without them.

How it is installed
Installation of the Green Toilet Lux 330
Most customers install the Lux 330 themselves or with a handyman – you usually don’t need a plumber or an electrician. It goes in on two levels: the porcelain toilet in the bathroom, and the bin right below it in a crawl space, basement or under a raised cabin.
Below the floor you need at least 37″ of clear height – even 38″ is a snug fit, so a little extra makes life easier – plus room to wheel the bin in and out. A waste pipe drops straight down from the toilet into the bin – 2 ft comes in the box, and longer pipes let the bin sit much lower, even a floor below. A vent pipe leads from the bin up through the roof, and a hose drains excess liquid to a canister. Everything except the rigid vent pipe is in the box.

How it is serviced
Service of the Green Toilet Lux 330
Servicing happens below the floor, outside the bathroom – and with the Lux 330 it’s rare: two adults full time typically swap a bin only about once a year.
When a bin is full, the swap takes just minutes, with no shoveling: unhook the liquid hose and the vent pipe, wheel the full bin out, close it with a lid and set it aside to finish composting. Then wheel the empty bin in and reconnect. A completely full bin is heavy, so many owners swap a little early.
While it rests, the compost usually matures in 6–12 months, depending on climate, into dry, earthy material. Use it on plants you don’t eat, or dispose of it as local rules allow.
Liquid: check the canister now and then – how often depends on use and climate. Empty it around trees and shrubs you don’t eat, away from water, or as local rules allow. More about liquid →

The time it takes for the composting containers to fill up varies depending on the number of users. In a typical family setting, a container usually takes at least six months to become full. Most households find that the standard package, which includes two composting containers, adequately meets their needs.

Can the Green Toilet Lux 330 be used in freezing conditions during winter?
Yes, the Green Toilet Lux 330 can be used in freezing winter conditions without any issues. While the composting process may pause due to the cold, this does not hinder the toilet’s usability.

Verified ownerThis solved a problem that we were having trouble with. Worked perfect!
Verified ownerI wasn't sure what I was getting into with this toilet system but since it was the only option I had for my off grid cabin, I rolled the dice and I'm glad I did. Installation took me longer than it should have with trying to figure out the best method, but after that it was easy. I installed it in July and have visited the cabin every month since then. There have never been any foul odors and other than losing a toilet brush inside, it's been great. I highly recommend.
Verified ownerFirst experience with a waterless toilet. Everything works as expected.
I can't provide pictures. The installation is in a high elevation, snowy location, that has already been winterized for the season.

Green Toilet 330 Spare Container
We live in Downeast Maine, and so far, I have been very happy with the setup! Our house was built on a pile foundation on a ledge, and it would cost more than usual to install a septic system, so we looked into other options. We had just enough room under the house for this size bin. (Note: we bolted the pressure treated boards to the ledge.) Also, I recommend getting the extra solar fan vent cover.
I will update my review after this winter as well.
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.
Just finishing the building of the lavatory. The system works perfectly. So thankful for the wonderful engineering and the environmental friendly aspects. Highly recommended.
Easy set up and GREAT customer service! The Green Lux toilet arrived and was very easy to set up. We built an elevated outhouse to make storage of the containers easy. We hosted a large gathering of 100+ people, and had several tell us that it was the most luxurious outhouse they have ever been in! Also, when the fan went out and the seat got cracked, they didn’t even ask questions, and simply sent us new ones! We will 100% be returning customers!
Composting toilet for off-grid cabin works well! After a great deal of research, I decided on the Green Toilet Lux 120 Composting toilet for my off grid cabin. The fact that I could install a replaceable bin under the cabin’s “in-house” toilet area was fantastic. The porcelain toilet is a perfect amenity – although I had to find a toilet seat to replace the one that was sent (cracked in shipping – but WTS reimbursed me to cover the costs). A rubber boot on the roof helps to keep rain out of the structure. The wind-driven fan works really well and helps keep the area ventilated. I keep a bucket full of wood mulch in the toilet area and drop 1 to 3 scoops after each use. I found some biodegradable detergent from Dr. Bronners that I mixed with water to spray down the toilet for cleaning at the end of our weekend visit. I also upgraded the provided vent pipe to a 4″ pipe.
Having a usable composting toilet in the winter makes our cabin so much more habitable. Thanks for making this product availalbe!
