I lived in Houston 1982 - 1987. The first house we rented (Lockshin Drive, west of Hwy. 6) had an odd feature that I've wondered about ever since:
The master bath had a bathtub and a separate shower enclosure. The shower had a regular shower head at the normal height. But it also had a bathtub spigot below the shower head. The spigot stuck out of the wall a 3-4", but was only ~2" above the floor.
WTF? What's it for?
