Extend Your GL 90 Composting Toilet Capacity with Ease

The GL 90 Extra Spare Container by Waterless Toilet Shop is the perfect way to boost the capacity of your GL 90 composting toilet. For seasonal use, the single spare container included with the standard GL 90 package is often enough. But for families or continuous use, adding extra spare containers ensures you’ll never run into limits. With additional containers, the GL 90 system offers virtually unlimited capacity.

Why You Need the Spare Container for Your GL 90

An extra spare container isn’t just about convenience, it’s about making your composting system smoother and more efficient.

Whether you’re planning for long-term use or simply want more flexibility, an extra container ensures your composting cycle never interrupts daily life.

  • Effortless Swapping: Once the active container reaches capacity, seal it with its lid and slide in a fresh spare. Your toilet is instantly ready for use again.
  • No Raw Waste Handling: The sealed container allows waste to decompose naturally outside without direct contact.
  • Efficient Composting: Decomposition takes 6 to 18 months depending on climate. Placing containers in a sunny spot and aerating with a garden fork speeds up the process.
  • Durable & Weather-Resistant: Containers handle freezing conditions without damage, keeping your composting process safe year-round.
  • Scalable Capacity: Adding spares expands your GL 90 indefinitely, making it suitable for continuous family use or shared setups.

How To Use The GL 90 Extra Spare Container

Switching is simple: when one container is full, replace it with a clean spare. The full container can then be left outdoors to finish composting safely. By the time all your containers are filled, the first one will usually have finished the decomposition cycle, leaving you with nutrient-rich compost ready to be used as garden fertilizer.

Please note: every new GL 90 composting toilet already includes one spare container. If you purchase the GL 90 system along with an additional spare, you’ll receive three containers in total: one with an open lid and two with closed lids.
