Bill Spikowski
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).

Arrived quick! The seat itself (not the pedestal which seems the more likely) was cracked on arrival. It was a bummer but the customer service is on point, sent not one but TWO replacements because the first redo was cracked too! Crazy. Anyway.. Gorgeous throne, 5/5 will poop again.

Great product and easy installation. Having dimensions online would help out, but other than that seriously stoked on it!

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.

Could not be more pleased with this composting toilet. Will definitely use again in a future project.

We finished our Green Toilet 330 composting toilet outhouse! Couldn't be happier with the product as well as the customer service/advice while ordering. The system is easy to use, which we thought was key for keeping up with it long term and encouraging others to try it as well. Was prepared to order from Finland a couple of years ago but project was delayed. Happy to find out there is a US supplier now!

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 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.

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…

Just finishing the building of the lavatory. The system works perfectly. So thankful for the wonderful engineering and the environmental friendly aspects. Highly recommended.
I have not purchased yet but I plan to come next summer. I just wanted to give some recognition to your customer service employee Nicholas who answered my call he was very kind patient and helpful to me he was able to help me decide on the gl 90 system for my off grid ranch. Thank you for your help it means a lot
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.
The perfect solution After years of consideration, this composting toilet was the solution. Instead of adding expense and time for a pool side bathroom, we constructed an adorable outhouse with the Green Toilet in mind. Added a solar powered exhaust fan to make the trips as comfortable as possible. We enjoy the novelty of it all and the unit is very clean with no odors.
Enjoying the GL 90 We bought a property with a small cabin on it with a composting toilet. It was terrible! Lots of trouble, stinky etc. So I went on the hunt for a new one and found the GL90. I had my handyman install it. Actually we added a separate room on to the cabin. It turned out really cute. And the GL90 fits right in. Looks sleek and NO TROUBLE and no stink!!
A Game Changer We bought a 100 year old cabin with no running water and needed and indoor solution. Wife said she wouldn’t stay there until she didn’t have to make her way to the privy in the middle of the night.
So, after tons of research on all sorts of composting toilet models, we settled on the GL90. Since we are able to access the crawlspace below, it made sense to choose a model that gets the “mixing tub” out of the bathroom and down below. We went with installation option #2 (only seemed appropriate since it is a toilet!).The result is a toilet that looks like a toilet. And, the porcelain pedestal feels just like a traditional toilet.
Installation was straightforward and simple with the exception of the plastic tabs that the bowl gets screwed into to lock it in place. Took a few times to get it all lined up and did end up taking the oscillating tool the tabs, but it all came together and is nice a secure.
To power the fan, I added a dedicated switch powered outlet so there’s never a doubt if the fan is on or not. Mounted the outlet out of the weather underneath the cabin.
Green Toilet 100 EZ Hits the nail on the ‘Head’! I just purchased a Green Toilet 100 EZ for use on our yacht club’s island. Setup was easy and the urine diverting feature a plus. The yacht club sailors, especially the women, are thrilled to have this for use before a race.
