Thinktank Composting Toilet

NOW AVAILABLE! Highly innovative, patented, Thinktank Waterless Composting Toilets. A major advancement in composting toilet technology.

Thinktank Waterless Toilets™ have numerous advantages.

  • Thinktank Waterless Composting Toilets are virtually airtight under normal operating conditions! They draw ventilation from outside – in contrast to other toilets which draw ventilation air from the bathroom area. With other toilets, you are rapidly blowing expensively heated or cooled air outside. The Thintank Waterless Composting Toilet, through its patented airtight design, draws all ventilation air from outside, circulates it through the toilet, and exhausts the same air outside. This saves a great deal of money over time, is far more efficient, and environmentally friendly.
  • Because the toilet is tightly sealed, ingress by insects is virtually impossible. This solves a major problem with other waterless and composting toilets.
  • The patented trap door design allows men to stand when urinating – in contrast to other toilets where men must sit.
  • The opening for solid waste is huge, with vertical sides. This overcomes most of the unpleasant clean up associated with many other waterless and / or composting toilets. With other toilets, waste can hit the sides of the bowl, making a mess. With the Thinktank, very little waste will hit the sides, and clean up is easier.
  • Thinktank Waterless  Composting Toilets use the best fans in the world. They have exceptional output (high cubic feet per minute rating), powerful static pressure (strength of airflow rating), are very quiet, draw low power, and have an incredibly long life (rated at 150,000 hours). Two fans are provided – one for the air intake and one for exhaust. However, in most installations the intake fan will be unnecessary and you can keep it as a spare. The intake fan is useful for very long runs of vent pipe. The toilets are designed for these fans to be easily accessible and removable.
  • All metal parts are high quality marine grade stainless steel.
  • The Thinktank Waterless Composting Toilet is incredibly strong. The shell is rotationally molded like a white water kayak. This is the strongest possible way to build something in plastic.  Rated at 350lbs plus. Big guy approved!
  • Thinktank Waterless Composting Toilet works on either 12 volt (a deep cycle 12 volt battery) or 110 volt power (normal household electricity) with the supplied wall transformer.
  • The urine drain pipe can be switched to either side with basic hand tools.
  • Uses inexpensive, widely available compostable bags.

Our previous waterless toilet would stink when we had a shower and turned on the bathroom fan. Not this one! Works as advertised. It's nice not to have to sit down to pee!

No odor, easy to use

This is a very nice, clean design. Exactly as claimed. No smell. It’s not over powered by our range hood fan, like our previous compost toilet. I’m happy not to be blowing warm air out of the bathroom anymore. Good customer service. Rare to get a knowledgeable person on the phone these days.

Works well

The installation instructions were very detailed, which was good. It took a few hours, but all went smoothly. We have had it 2 weeks and it is working fine. It's very quiet, and seems well made.
