Why hot tubs are high risk
Spa water sits at around 35 to 40°C, perfect for bacterial growth, and the bubbles create an aerosol that people breathe in. Outbreaks have been linked to hot tubs in hotels, holiday parks and even on display in shops.
What good management looks like
- Continuous disinfection with correct chemical levels
- Checking and recording pH and disinfectant levels several times a day when in use
- Regular filter backwashing and cleaning
- Regular water changes
- Periodic microbiological sampling
- Trained staff and a written management plan
Guidance to follow
HSE's HSG282 covers commercial spa pools and HSG274 Part 3 covers other risk systems. Holiday lets with hot tubs used by paying guests are treated as commercial.
Frequently asked questions
Do holiday let hot tubs need a legionella risk assessment?
Yes. A hot tub provided for paying guests is a commercial spa pool and must be risk assessed and managed.
