No, the post was for a hydro massage tub (whirlpool/'jacuzzi'/etc) in a residential unit; for use by the occupant of said dwelling.
OK, now before I get jumped; NOT a common area tub in a complex; or in a gym, health club, etc.
The above post is 'common practice' here for resi.
Comm is another story.
'Confused in MA', I really doubt that!
"Jacuzzi" is like saying "Romex", George. My 'bad'! A hydro massage tub, fill it, enjoy the bubbles/jets, have fun, & drain it out
