What temperature should a hot tub be set at in the winter?

The temperature of your hot tub shouldn’t change during the winter months. The recommended range is the same year-round being somewhere between 38-40°Celsius (100-104°F). Never exceed 40°C (104°F) due to safety concerns.

The only thing that changes during the colder climates is the potential heat loss from your hot tub if it’s located outdoors. The colder climate may cost you a little more to maintain a consistent temperature.

Although you may think the colder season may affect your spa experience, the temperature you enjoy won’t change once you’re having a soak.
