Gyms/Spas/Facilities with soft water?

Called various gym locations (24 hour fitness and Planet Fitness) in south bay area and none of them know what I’m talking about when I ask if they have hard or soft water in the showers.

A family member recently moved in and is severely reacting to the hard water. I scheduled to install a water softener system by a professional but it won’t be until about two weeks or so/more.

So, willing to pay for a short term membership somewhere as a temporary solution.

TIA!
