Hot tubs


D Alt

Recommended Posts

Under the CDC inspection guidelines for whirlpool spas on cruise ships:

  • The water must fully circulate no less than every two hours.
  • Water must be changed every 72 hours.
  • Granular filters must be cleaned and inspected at least every 72 hours and replaced every 12 months. 
  • There are required ranges for pH and chlorine levels. 

But that is the minimum--cruise lines are acutely aware of the possibility of any disease spread or bad health inspection records. So I believe @twangster is right and they are generally drained and cleaned more often than that.

FIFY

Haha, truth!

I am a bit of a germaphobe, and it may seem weird, but I have never felt like the hot tubs were dirty or gross on a RC cruise.  Some people are appalled and say they would never dare go in a public hot tub, and for me that holds true a lot of the time, but I really do think Royal does a good job with theirs as far as cleaning goes.  It wouldn't surprise me to hear that they are drained and cleaned nightly.
