When setup for use, the Thunderbox stands 15.5 inches high - the same height as the standard home toilet - with a seat area of 15.75” X 15.75”, or total area of 1.7 square feet - allowing for a comfortable and stable area for a “sit down”. When erected, it has a solid “footprint” that makes it very stable, and it has been tested up to 500 lb weight capacity!

For Liner purposes, the total opening size is 57 inches, so any trash bag with a width of 30 inches (with a corresponding circumference of 60 inches) will work, although we highly suggest you always use degradable / compostable bags… Save the Planet!

When folded for storage or transportation, the Thunderbox measures 15.75” X 15.75” X 1 inch thick, and weighs only 9 pounds.

We include a “starter pack” of 2 our Inviro bag / liners with every order of the Thunderbox™.
