Just go on the floor.

Photographed in the basement convenience store of a building somewhere in northern Seoul (서울시), or just north of Seoul, South Korea (대한민국), this section of the bathroom floor is the toilet. Though not easily visible due to poor lighting, urine drains through a hole in the wall into the ground under the building. The pan and water pipe allow you to "flush." For defecation, employees and customers go upstairs and use, presumably, more familiar bathroom facilities.
