A shower in the balcony would �compel� people to experience nature every day. Every morning the drizzling of water and the greenery of foliage would launch the user in to a new horizon purifying mind and soul towards the horizon. Nowadays people might travel thousands of miles to find spirituality in a tropical paradise, but now your balcony is your tropical paradise!
While in the winter the shower can be enclosed by glass in the summer it can just be enclosed by an flowering curtain and climbing plants thus experiencing the blossoming and falling of seasons.
The water used during the shower would be just collected in the drain channel in the balcony and used straight away to regularly watering the plants. An outdoor shower in the balcony would increase the floor space available inside your apartment allowing you to make or instance a larger living room. Up to the designer to find the best spatial solution to fit the outdoor shower with the internal arrangement as well as to use the shower as a water feature.
In the attached images, it is just a basic example �Shower on the sky�, fundamentally my idea is to look for a alternative as well as simple spatial planning to match a more funky and pure urban life style, where people are led into more spiritual and sustainable approach.
