The closed-system Mulltoa 20 Waterless Composting Toilet has all the basics for good composting.
Similar in size to the MullToa 45, the Mulltoa 20 is without an additional heater. 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!
Without any water or drain to connect, the Mulltoa 20 accelerates the natural decomposition process and
evaporates excess moisture. Material in the upper chamber is finished in the lower chamber and eventually
emptied into a garden composter. Under vacation use the finished compost is emptied only once or
twice a year!
Using efficient Swedish technology electrical consumption is very low. The MullToa 20 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 MullToa 20 does not require space under the building as the whole unit is “above floor” and is easily
installed in about 3 hours.
The MullToa 20 comes with Mulch, a standard vent installation kit (8 ft interior vent pipe, 4 ft exterior
vent pipe, insulation, roof flashing, insect netting), and manual mixing rake.
Additional Vent pipe, 45º Elbows and Mulch are available separately.
