Biolet Composting Minimum Usage

  • $ 1,99900


The BioLet 25 is the world's first fully automatic composting toilet. In our quest to provide our customers with a toilet that is as convenient to use and operate as a flush toilet, a fully automatic mixing system has been added to the quiet fan and thermostatically controlled heaters. 

The BioLet 25 is an excellent choice for that extra bit of luxury in the cottage, barn, basement, pool house, or any place where a conventional toilet is impractical. Designed with the smaller family in mind the BioLet 25 is the perfect choice for those applications where the extra capacity of the 65 is not needed.

Rated at 3 people full-time use and 4 people part-time use the 25 is an excellent choice for the cottage, basement, barn, pool house or any place where a waterless toilet is wanted.

Equipped with a thermostat, fan, automatic mixer and double heaters the BioLet 25 is the easiest to operate composting toilet on the market today. As with all BioLets the 25 is easy to install by anyone with basic handyman knowledge in just a couple hours using common household tools.
