For those who asked about the water being too hot, in Europe many sinks have a cold and a hot spigot on each side of the sink, (unlike in the US where you choose the degree of heat coming from a single spigot). You fill the sink with water from both pipes to create lukewarm water then use it from the basin. So, I would imagine he fills his basin with hot, then adds cold and uses it that way.
Good for him!
