Do all composting toilets need to be emptied?

I have a tiny home in Virginia that needed an upgraded bathroom. I spent a long time investigating composting toilets online and watched a lot of YouTube videos explaining how each works. I knew from experience that separating urine from solids was important for keeping the composting process odorless. The only toilet design that made sense for carefree emptying and separating was the Green Loo. Also, I didn’t want a plastic toilet but an attractive ceramic one. I decided on a Green Loo CF-4 continuous composting system. But how to get it to the East Coast? I decided it was worth paying several hundred dollars in shipping to get the Green Loo, which is only sold in the U.S. in Nevada, to the East Coast.

The toilet arrived on a huge truck that wasn’t willing to come down my dirt road and driveway, so a neighbor ended up picking the box up at the main road in his front end loader and dropping in my yard. I had a builder install it and, and despite some cussing and finessing, he got it hooked up and working in a day; some small parts (bolts and such) had been lost through a hole in the shipping box. (It wasn’t packed well for long-distance shipping). I am very pleased with the quality of the toilet, and the split system’s heavy duty plastic tank under the floor is sturdy and well made. I could tell it had been banged around a lot in shipping and aside from a few scratches it had arrived unscathed.

I used the Green Loo for a month without the fan to see if I needed it. The system worked in the sub-freezing weather; however, there was a slight odor, so I had the builder hook up the fan that came with it. Now it’s totally odor free. I plan to get the solar panel to run the fan, which is very quiet. The unit comes with a bag of Bokashi, and I ordered more Bokashi on Amazon to jump-start composting. I am using peat moss as a composting medium, but plan to switch to the more sustainably harvested coco coir. The CF-4 model is an excellent product.

Dug a 3 foot hole and filled it with lava rocks then pavered over it.

Looks and works great!!

Thank you

Installed our GL 90 compost toilet in our small cabin. It pretty simple, just remember measure twice before cutting.
The Wife and I used it for 1.5 months before I decided 5o switch the waste tank out.
I was not sure what to expect, the waste container is under the cabin. I lifted the lid just pulled it out. There was no smell no excess liquiods.
It was a very simple swap.

We installed the Green Loo 90 in our tiny house build and we couldn’t be more pleased with the final product. Because we live in a very cold climate, we had to do a creative installation to account for our extra thick floor insulation, but Eemeli at GreenLoo was incredibly helpful and gave us some great suggestions. We’re very impressed with the quality of the components and the ease of installation. When we needed a toilet seat replacement due to an overzealous delivery guy, Eemeli was right there to the rescue and had a new seat to us within a few days.
We cant recommend GreenLoo enough. it's a great product from a wonderful company with absolutely amazing customer service.

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!

We have been building a small, off grid hut/cabin on our Utah mountain property. We were looking to build something small, simple and low maintenance. Our power is all 12 volt solar and we carry in water. This cabin will be seasonal (no septic)so the toilet had to be simple too. Other composting toilets have too many moving parts and a low capacity. After much research we decided on the GreenLoo GL90. I love the low profile composting bins. We decided to build an attached mechanical room/outhouse/shower room and built it to suit the toilet specifically. The GL90 porcelain toilet is tall and easy to keep clean. I ordered the 12v vent fan with my kit and it works perfectly NO smell at all! I turn off the solar when we leave so I was concerned it would smell upon our returns. So far so good! We are going to install a “whirlybird” wind activated vent cap to vent in addition to the electric fan while we are away from the cabin. Install of the GL90 was a breeze and it looks great! Big thanks to the good folks at The Waterless Toilet Shop for their friendly support and expertise.. and a full line of supplies and accessories! I’m adding some photos of the Toilet and build so far!

We built a short term rental cabin on our homestead to creat another income stream in an environmentally sustainable way. After growing up off the grid, and traveling/camping around the world, my wife and I have tried just about every composting toilet system on the market. We have even owned a few of the nicer brands, but never found one like The Green Loo. This system far exceeds the competition, and has everything we want in a composting toilet system. Most notably, it is easy and straightforward to use, easy to clean/service, and is made of quality components that are meant to last. I am a carpenter, but the installation process is simple and can be done with basic carpentry knowledge and tools. The instructions that come with the toilet are also very Clear and helpful. Ordering from the waterless toilet shop was great, Eemeli is very responsive and communicative. Eemeli helped me with my custom chute order, and when the shipping company damaged, then lost the chute, Eemeli immediately sent me a replacement. I highly recommend ordering from the Waterless Toilet Shop, they offer quality products at competitive prices and customer service and support that goes above and beyond what is customary.

We are pleased to hear of Greenloo’s expansion to Canada/US markets. We are very happy with our GL 90 maximizer composting toilet. Instructions followed make a comfortable and sophisticated toilet situation. The unit was well received (exception whirlybird fan option was slightly damaged - not Greenloo fault - aside from shipping damage we needed to remove and reinstall the fan’s interior veins as they were upside down? Just so you know).
We live in a rural area, off grid and the two of us provide the Greenloo continuous use as we live here full time. It is an excellent unit overall particularly when compared with competitor models of strange or potentially messy maintenance no one wants for sure. We dug a big hole and filled with compost from toilet for our lovely maple tree (not edible and ornamental) and it is doing great. Thank you for a great product.

By far the best looking throne in the composting market. I had mine shipped from Australia. It was packed with great care and arrived in mint condition. Service was responsive and very friendly.

Great system, really happy with the quality and setup. perfect for an off grid setup

Enjoying the ease of care and maintenance for our composting toilet. Highly recommend the water faucet to clean the bowl after use. Ours was a smaller chamber because it a new build in a concrete slab so we used the slope of the land to enable the chamber to sit beneath the pedestal. Very happy. We have two. One in the main house and exactly the same model in our cabin.

The toilet I have bought 5 years ago is great. Easy to install. Easy to change storage.
Feels wonderful to sit on. Awesome having no smell in bathroom.
Good price also.

Being fully off grid and on a site with a very high water table, conventional septic tank options are not appropriate for our site, and a high energy consuming aerobic system is out of the question.
This installation is a stand alone facility we call the TajMaLoo and will be a trial run for including a Green Loo CF4 in our future container house project.

We purchased a Green Toilet last year, importing from Finland, and we are so pleased you have a store in the USA now. We have found the green toilet wonderful to use at our off grid island cottage. It is easy to use, and without odors one associates with an "outhouse". It is easy to swap out the containers and this works very well for our purposes.

Customer service, communication and care are amazing!

Needed dry material for my composting toilet. Fast delivery!
