The Nature Loo™ Classic 650 system is specialized in its designing for Tiny Homes (TH) with a low underfloor clearance requirement of 450 mm, making it very suitable for transportable housing and most retro installations. This composting toilet model is suitable for a couple looking to install a composting toilet in their tiny house.

The Nature Loo™ | Classic 850 system is designed to meet the larger capacity requirement of a few users to a family unit with a chamber (tank) underfloor clearance requirement of 750 mm

The Centrex 2000 A/F (Air Flow) NE is a low voltage, waterless “off-grid” alternative to the straight Centrex 2000 model. The system is designed for use in conjunction with a waterless toilet pedestal and processes waste under the bathroom floor, the non-electric system is slightly smaller than its electric counterpart.

Perfect for medium to heavy seasonal or light residential use, the Centrex 2000 NE allows for both a longer composting cycle and larger waste volumes.

The Sun-Mar Centrex system range is a split system, also known as a under floor model. This mean that the holding chamber is separate from the actual toilet pedestal itself. The major advantages of these systems is that they allow for greater holding capacity and therefore tend to be lower maintenance. If you have below floor space for installation, then this is the range for you.

Perfect for medium to heavy seasonal or light residential use, the Centrex 2000 allows for both a longer composting cycle, and larger waste volumes than the 1000 models. The increased surface area in the evaporating chamber coupled with the larger heating element also provides better evaporation on electric units.
