The  Biolet 25a Waterless Composting Toilet is the perfect choice for your boathouse, bunkie, pool cabana, and even as a second (or third) toilet. 

The Biolet 25a is easy to install and use. It plugs into a standard electrical outlet.  It is easily placed almost anywhere.  Simple perfect.  No Odours. You can have a toilet lakeside in your boathouse, or poolside in your cabana.  Anywhere.

How does it work? 

Super easy, and brilliant technology.

Sitting on the toilet seat opens the trap doors; closing the toilet seat lid after each use activates the stainless steel mixing mechanism that efficiently breaks down paper and distributes moisture into the compost material in the upper chamber. Once a week or as needed, mulch is added through the toilet seat opening. That is it!

The Biolet 25a Waterless Composting Toilet accelerates the natural decomposition process and evaporates excess moisture. The material in the upper chamber is finished in the lower chamber and eventually emptied. Under vacation use, the finished compost is emptied only once or twice a year! 

Using efficient Swedish technology electrical consumption is very low. The Biolet 25a Waterless Composting Toilet uses approximately 64 watts per person per hour (averaged over a 24 hour period). When you are away for more than two days, just shut it off! It does not use any electricity when you are away.

The Biolet 25a does not require space under the building as the whole unit is “above floor” and is easily installed in about 3 hours.

The Biolet 25a comes with 2 bags of Mulch, a standard vent installation kit (approximately 8 ft interior vent pipe, 4 ft exterior vent pipe, insulation, roof flashing, insect netting), and manual mixing rake.

Additional Vent pipe, 45 degree elbows and Mulch are available separately.

Flat-rate shipping fee of $375 to most of Canada.
