Easy Fit
The Composting Toilet dimensions: 1200mm x 1165mm x 2170mm
Easy to maintain
Maintaining the Composting Toilet MKII is easy. There is no need to move the whole toilet to service it; it can be done by simply remove the top half. From here, there is access to the full tank which can be removed, transported and emptied for composting.
Wood Plastic Composite (WPC)
The walls and roof of the Composting Toilet MKII are made out of Wood Plastic Composite (WPC). This makes the toilet resistant to extreme temperatures either high above or below zero and UV exposure increasing the longevity and endurance of the building. In place of our normal timber designs, WPC makes transportation to rural areas easier. Coming in flat pack for ease of assembly at any destination, the WPC is virtually maintenance free.
The Composting Toilet MKII features a solar powered fan assisted ventilation pipe, which helps to remove unpleasant odours. This fan actively draws the odour out of the structure rather than waiting for it to rise, a process called positive ventilation. The fan will continue running for approximately 15 minutes after you've left the structure, in similar fashion to a domestic extraction fan.
Avoid unpleasant odours
The waste deposited in the 44-litre collection tank gets sprinkled by peat from the upper tank absorbing moisture from the waste. Peat is a unique natural antiseptic and absorbent, which provides a sanitary coating for the waste, initiates the beginning of the composting process and removes unpleasant odours.
Solar Powered
Our Composting Toilets can stand independently from electricity sources due to the solar panel on the roof. This solar panel charges a 12V battery pack (not supplied) which, in turn, powers an electric water pump that feeds water through to the sink so you can wash your hands. This also powers a multi-charging point which helps to keep the phones charged.
The Composting Toilet MKII does not use any water so is an ideal solution for private Holiday Homes, Gardens, Farms. Water is still needed in a container for use with the sink.
