The All New Biolet 55 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 regular flush toilet, a fully automatic mixing system has been added in addition to the quiet fan, compost covers and double heaters.

The BioLet 55a is an excellent choice for that extra bit of luxury for any location where a conventional toilet is difficult or impractical to install. Designed with the smaller family in mind the BioLet 25a is the perfect option for those applications where the extra capacity of the BioLet 65e is not needed.

Rated at 3 - 4 people seasonal use the BioLet 25a is an excellent choice for the cottage, basement, barn, pool house or any place where an easy-to-use and convenient composting toilet is wanted.

Equipped with a compost cover which hides any content from view, fan, automatic mixer and double heaters the BioLet 25a is the most convenient composting toilet on the market today. As with all BioLet toilets, the BioLet 25a is easy to install and very easy to maintain.

BioLet unites the natural composting process with advanced technology accelerating and optimizing biological decomposition, evaporating excess liquid and exhausting odors… all within an elegant bathroom fixture that is easy to use and economical to operate.

The closed-system BioLet toilets are fully automatic electric toilets that anticipate yourevery move! Sitting on the toilet seat opens the trap doors; closing the toilet seat lid activates the stainless steel mixing mechanism that efficiently breaks down paper and distributes moisture into the compost material in the upper chamber. Material in the upper chamber is finished in the lower chamber and eventually emptied. The BioLet 65 features LED maintenance indicators to let you know when it is time to empty the lower chamber. The non-composted portion and the dry, composted portion are kept separate.

BioLet Composting Toilet 25A

A fan circulates warm air under and around the compost for fast decomposition and evaporation of liquid. A float switch operates an additional bottom heater if excess liquid is detected. Once a week or as needed, mulch is added through the toilet seat opening.

Using energy efficient Swedish technology, electrical consumption is very low with an adjustable power setting, which is adjusted according to the number of people using the toilet. When you are away for more than two days, just turn off your BioLet!
