I am afraid that the Germans are far more disciplined, than us Brits, when it comes to having a shower before going into the pool. The shower also helps to reduce the amount of sun cream/oil that gets deposited in the pool.
I must admit that the title of this topic made me chuckle. "Hard to reach places?" Is that why, when around the pool, you see most of the sand on the "bottom"?
