Why would you think europeans are likely to waste more water than americans.
Is it because you think they take fewer showers (maybe some of them).
Knowing how europe loves to regulate (everything) I'm suprised you're
allowed to use any water for a shower (just kidding).
As indicated, modify the showerhead you buy by drilling or removing the
water restriction (often just a plastic washer they can resize as the rules
change). What you do depends on the design of the head.
Not as simple for a toilet though (dual tanks???)
