Now, here is the interesting part, look at the sink inside the WC, me and my colleagues have been discussing about what is the use of designing that particular sink inside this narrow WC. A person said that you can spit into the sink while you are doing your business, some people said you can wash your leg, I said that certain people can wash their hand and ass with the water supply, etc... Until now, the sink remain as a "mystery" that nobody knows what is the real purpose to have that.
