We are accustomed to having a removable overhead bar in the shower. This is convenient for hanging wet towels and rain coats as well as creating extra closet space. Home Depot had the end cup/socket pair of connectors and an adjustable length closet bar. Installation was easy.

Bonus: I am 5' 9". It turns out the bar is so high that I never have to think about removing it to take a shower.
