Still in the concept stage, the Phyto-Purification Bathroom and Shower would make your bathroom more environmentally friendly:
Using a natural filtering principle called phyto-purification, the bathroom becomes a mini-eco-system by recycling and regenerating the wastewater.
The water from the shower and the washbasin is filtered through an organic system before being re-used.
Phyto-purification is a natural water-recycling process which is commonly used in ecological purification systems.
