Lars has made some observations about showers.

Finland NZ
good, steady water pressure good pressure, for rain
hot water is hot at once hot is cold, but gets hot after a refreshing shock
temperature changes quickly same-day temperature changes!
hot water does not run out ditto, assuming personal boiler
detachable shower head (for feet!) user is expected to be a contortionist

On the whole, showers in New Zealand hotels, motels, and rental apartments are fine, just a bit on the cold, unpleasant side.
