Hot Tubs Can Kill: Biofilm, Bad Habits & Vacation Rental Risks with Dr. Roy Vore

Ask a question here

That vacation rental has a hot tub. Great. When did somebody last test the water?

Natalie Hood welcomes microbiologist Dr. Roy Vore back to the Talking Pools Podcast for part two of their hot tub myth-busting conversation. This time, they get into the plumbing, the maintenance shortcuts, and the uncomfortable questions every service professional and vacation rental owner should be asking.

Roy discusses biofilm management, the limits of shocking, and why he considers once-a-week service inadequate for busy vacation rental hot tubs. Natalie also asks the question guaranteed to settle an argument in somebody’s house: Does sitting in a hot tub count as taking a bath?

Between the laughs, the conversation gets serious about guest safety, operator responsibility, and charging enough to do the job properly.
