Our Compost Toilet features a Urine Diversion System which reduces the water used and wasted on flushing, and is ideal for locations without access to a sewerage system or have a lack of water.
Easy DIY
The Compost Toilet is designed to be easily installed and comes with clear instructions and the necessary fixing pack.
Avoid unpleasant odours
By diverting urine and separating waste, the process of fermentation is prevented, and so are odours. Further protection against unpleasant odours is improved with our unique designed toilet lid that incorporates a rubber seal.
The Compost Toilet has a ventilation pipe with a fixed air vent to direct the flow of air and ensure the eco toilet is well ventilated.
Slow grown Spruce
We use slow grown spruce for the walls of all our interim housing as it is better all round than pine. Our mature timber is much less likely to shrink, warp or split. It is also less likely to sap, which means it is not going to ruin clothes or furnishings.
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.
