designer's own words:We are using every day and where the bathroom is often used. The water we use every day here, which essentially use the same water use, such as a washbasin or a wall due to the use of all the people, and signs of spring water remains. so frequent cleaning is required for public toilets. Due to the use of many of the remaining traces of water every hour of cleaning is impossible due to these signs of water does not clean the bathroom. Dry eyes are also difficult to find a place to avoid the water because it tells us where the lighting is the same role. So I left the wall or sink, etc. does not show clear traces of water droplets, not unusual for one brief moment, one of the pictures, wanted to be seen as a fun role.
