What a stupid design!

OK, this is the sink in my bathroom. There are 2 faucets, one for hot water, the other for cold water. Can you think of anything wrong with it?

Well, hot water is too hot, and cold water is too cold, to wash hands or face. How do you get water with intermedia temperature? Pour the water into the basin. Comparing to the sink with single faucet and two controls (like the one in my kitchen), this design definitely wastes some materials and it also wastes water. If you want to wash hands with warm water, you have to fill the basin with certain amount of water, which is usually more than the amount that is really needed for washing hands. The same goes if you want to wash face.

And this is a very popular design for bathroom in Ireland. Most of the sinks I have seen so far are using this design. Who comes up with such a stupid design?!
