After a week in a Vegas hotel, it was such a relief to come home to real water pressure in my shower, although I do understand why a city in the desert legislates low-pressure nozzles. I'm not sure I am unreservedly in favor of hacking showers, however. I stayed in a hotel in Sicuani, Peru once where the hot water function was a bare 220V wire wrapped around the water pipe. That woke me up—as did the cold shower I took after making sure the wire was disconnected. I think I may have even turned off the bathroom light just to be on the safe side.

This article recommends a safer hack, so you might be okay.
