Take the bad showerheads and pawn them, or put them on Craigslist, then buy the ones you want.
In the less expensive hotels I have stayed at, the kind with the shower down the hall, the shower heads were always gone. The manager said that they were stolen on a regular basis. hard to imagine a market for hot shower heads, but there it is.
The low-flows will drive you crazy if you have a big family!
Stanford? I thought they were supposed to be smart. How hard is it to go down and buy a $5 shower head. I used to work on the road and my Shower Massage was the first thing I packed. Especially in southern Cal. They had water restrictions almost everywhere I stayed.
It's easier than that. The heads usually have a plastic flow restrictor that is removable. Pull the head, punch out the restrictor, and put it back on.
It's that simple. If I were the Stanford student body, I wouldn't be so overt about advertising the incompetence of the mechanical engineering department.
It might offend the alums, most of whom know better. Eh sasquatch? ;-)
