The GL 90 Batch composting toilet is designed with both efficiency and environmental responsibility in mind and offers an exceptional waste management solution making it ideal for cabins, tiny homes, RVs, and remote locations.

The GL 90 Composting Toilet is designed for off-grid sanitation. It is designed with a split system toilet feature with a stylish porcelain pedestal that connects to a composting container located below your floor level. 

Compared to traditional toilet systems, the GL 90 Composting Toilet does not require flushing. This feature makes the GL90 an ideal toilet solution for remote and off-grid locations. 

GL 90 Composting Toilet Features and Benefits:

Split System and Batch Composting

The GL90 is designed with a split system to keep the toilet and composting unit separate from each other to ensure a clean indoor toilet experience. Simply swap full containers with empty ones and it is all done outdoors thanks to the Split System. 

Adaptable Capacity for Diverse Needs

Thanks to the GL90 Composting Toilet's simplicity, it is easy to integrate into different living and toilet situations making it the perfect toilet solution for AirBnBs, Homes, and more! Also features the option to add more containers to cater to your toilet needs. Say goodbye to complicated instructions and say hello to simplicity that works! 

Advanced Odor Management and Ventilation

The GL 90 Composting Toilet features an odor-free experience thanks to its advanced ventilation system. With proper airflow, the system gets rid of any odor and enhances the composting process while doing so.

Efficient Moisture Control

Thanks to its double base and capillary tray, the GL 90 is able to separate excess liquid from solid wastes to maintain optimal moisture. This is a very important feature to maintain the ideal moisture for composing and for an odorless experience.

User Friendly

The GL 90 is a toilet for all. With its simplicity and straightforwardness, anyone can install and use this composting toilet without the need for complicated and detailed instructions. The GL 90 composting toilet is built on a simple swap foundation method which makes it easy for anyone to use. Simply remove the full container and replace it with an empty one. 

How does it Work and How to Use the GL90 Composting Toilet

The GL 90 Composting Toilet works like your traditional toilet but without having the need to flush. That is because all waste falls directly into the Composting Container below. The Waste falls inside a dark container and ensures no visibility. The ventilation system then gets rid of the odor and enhances the composting process of your waste. With all of this together you get a fresh, clean, and odorless indoor toilet experience.

We highly recommend that after using the GL 90 Composting Toilet you add a cupful of covering material like hemp over the waste through the Toilet's opening. And to improve the composting process you can occasionally stir the compost and level it for a more efficient breakdown process. 

*Please do not throw sanitary towels and plastics inside your GL 90 Composting Toilet. These products are non-compostable and should be disposed of in a separate bin. 

How to Install the GL 90 Composting Toilet

There are two primary methods for installing and servicing the GL 90 composting toilet. Typically, the GL 90 composting container needs to be installed directly below the toilet pedestal inside. Depending on the clearance height below the floor level, the toilet can be installed and serviced in one of two ways:

Option 1:

The container, along with the lid and the waste shaft, is pulled out as a single unit.

Option 2:

Option 2 is generally more common and preferred for most installations.
