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.

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.

Let our customers speak for us
I have been servicing and installing composting toilets for 17 years at a seasonal cottage community. Recently I installed two of the UD pedestals for a client, I was very impressed with the quality, as was my clients. The toilets are superior to any brand I've encountered, sunmar, envirolet, nature head, all use thin plastic components. These sturdy porcelain like youd fine in a real bathroom and clean better and dont stain like the plastic ones.
Love the ability to move where the waste pipe and exhaust pipe are installed on the unit, it allows for many options when installing so you can optimize the functionality of the unit. Other units you have to compromise constantly because of the hard mounted penetrations.
We are very pleased with the experience of the GL90. Everything was of good quality and mostly easy to install. The porcelain throne is very high quality and looks very nice. There is absolutely no odor. We had to turn off the power to the fan a couple of times, and there was only a faint smell of fresh pine shavings and hemp. We also inadvertently discovered that the hemp shavings are far superior to pine in the absorption factor. We see now that is explained on the website. We are temporarily using a 5 gallon plastic bottle for liquid containment until our leachate system is complete. At first we were using the supplied hemp and had little to no liquid in the bottle. When we ran out of hemp, we used some local pine shavings and noticed the bottle filled up much more quickly. I'm thinking that using hemp will allow the moisture to remain in the pile longer and allow the fan to evaporate more liquids. Hence, making for less emptying of the liquids container until leachate system and filter is installed. It did take a few return trips to town to get the 4 in vent plumbing that I could make work with supplied fittings. I would suggest giving specific instructions and materials for the type of pipe and fittings that will actually work to save people the time and effort. Fernco fittings saved the day. It was more of a challenge than I anticipated with the various 4 in pipe available on the market. AI wasn't totally accurate either because of the metric to imperial conversion. I'll post pics in the near future for reference of what worked for me. The other small details of installing the porcelain toilet: the measurements for placing the toilet mounts seemed to be a bit off and I had to screw in at an angle to get it to work. I measured several times. Also, one of the screws that secure the mounts to the floor broke as well as i was driving it in. I found a more stout screw for that. With those small details the system still rates a 5 in our experience. Service and product are exactly what we had hoped for. Thank you Nicholas.



Our GL90 is up and running; we just swapped out the container for the first time. I really love how small the composting container is, and bought an extra container in case it requires removal more often than projected.
Our situation had a number of odd wrinkles:
❖ This is an elevated house; the living area including the bathroom is 8' off the ground. The area below the house is unenclosed, so we didn't have typical space constraints.
❖ We were replacing an original "Carousel" compost toilet from the early 1980s, so we had to line the GL90 up with the original chute, and find a way to connect it to the original vent pipe.
❖ One complication is that the old Carousel was destroyed by flooding from Hurricane Milton. It was raised less than a foot above ground, and the roaring floodwaters came up about 3 feet. So wanted the replacement composting container to be elevated as high as possible. My solution was to hang it from the ceiling below the house, to avoid any structure under the container that could get washed away if we get another flood like that (even if the container itself was above the flood level).
❖ Another complication, this one self-inflicted, was that I was also reinstalling the fire sprinkler system and the water heater, both of which were also destroyed by flooding, and needed to be elevated as well -- and for various reasons needed to be in almost the exact location where the toilet needed to go, and needed to be protected from wind-driven rain.
I did have a few technical problems with the GL90:
❖ I was aware that the hose and vent fittings on the GL90 were metric, but I hadn't realized that the nominal metric sizes used in Australia are different than nominal metric sizes for hose and pipe made everywhere else in the world! After numerous false starts and then deep research, I finally figured out ways to make everything work -- but that wrinkle alone took this project way beyond the DIY world. Good thing I love a challenge, and have technical and research skills...
❖ We had a serious fly problem shortly after we began using the GL90. I still am not sure exactly why, but I did notice that the lid doesn't fit tightly on the container. The three clamps just aren't enough to keep even marginally fly-proof. My solution has been decidedly low tech: a brick on the lid between each pair of lid clamps. It's also possible that the exhaust fan is too weak; I've purchased a replacement that should move twice as much air.
❖ I still haven't figured out how to keep the toilet seat on straight. It keeps moving off center, and I'm afraid to tighten the connecting screws any further; they don't seem that robust. The brackets hold the toilet to the floor don't seem that robust either, but the toilet has stayed in place, so I don't want to argue with success (and I'm managing to avoid permanently fastening the toilet to the beautiful terra-cotta tile floor in the bathroom).
