Preserve the spa from freezing

Protecting your hot tub from freezing is a topic that comes up every year for all outdoor spa owners. Here are some practical tips to help protect your equipment for the long term.

Freezing temperatures can seriously damage your spa and equipment. Fortunately, there are simple solutions for those who want to winterize their spa or enjoy its benefits all winter long.


Passive wintering

Passive winterization is recommended when the risk of freezing (day and night) is high. While the preparation is a little more time consuming and thorough, once it’s done you don’t have to do anything else all winter or worry about freezing!


  • Turn off the power to the spa
  • Drain the spa and the pipes. Add anti-freeze product
  • Carefully clean filters and store them in a dry place
  • Clean the spa (do not forget the water line)
  • Put plugs on the blowers/circulation points (optional)
  • Cover the spa with a suitable cover

Active wintering

Active wintering is recommended in regions where winter is not too severe. It has the advantage of being quick to do: after cleaning and anti-algae treatments, you just have to cover the spa, keeping the water at the bottom and filtering the water for 1 hour a day.


  • Clean the spa thoroughly with appropriate products
  • Clean the filter
  • Check the pH (must be between 7.2 and 8.4)
  • Add your usual disinfectant products
  • Maintain the water temperature at 15°C (59°F)
  • Adjust the filtration 1 hour per day


Enjoy your spa all winter

Rules to follow to enjoy your spa in winter ! 

Despite popular belief, during the winter months you should be particularly vigilant about water sanitation because large temperature changes can have disastrous effects on water chemistry.


  • Analyze the water (pH, TDS, Chlorine) daily
  • Clean the filter very regularly (depending on how often the spa is used)
  • Use an appropriate spa cover to prevent impurities and save energy
  • Maintain water temperature from 30°C  (86°F)
