When you choose a Hot Spring spa, you’re not just buying a hot tub, you’re making a long term investment in your health, vitality, and well being. Like any piece of fitness equipment, your hot tub will provide maximum benefit when you use it regularly. When it’s always ready and set to the perfect temperature, your hot tub can become an essential part of your daily routine.
Determining your ideal temperature is key to getting the most out of your hot tub experience. There are several variables to consider. To make sure you have all the facts, we’ve pulled together some common questions Hot Spring owners have asked about water temperature, along with answers from our experts:
What temperature should a hot tub be?
While the ideal hot tub temperature varies from person to person and depends on factors such as age, health, and personal preference, there are some recommended guidelines to keep in mind.
Set temperature at or below 104 degrees for adults.
The US Consumer Product Safety Commission has determined that temperatures above 104° Fahrenheit (40° Celsius) are dangerous for adults because they can lead to heatstroke. For a comfortable soak, most people set their hot tub between 100° and 102° (37.5–39°). Healthy adults are safe to soak at these moderate temperatures for twenty minutes at a time.
Start low, then gradually raise your spa temperature.
Set your spa controls to 98° or 99°, and as you soak, increase the temperature gradually until you can enjoy an invigorating massage without feeling overheated. If you have the urge to get out or sit on the cooling step after a couple of minutes, that’s a sign that your water temperature is too high for comfort.
Consider the preferences of everyone in the tub.
When soaking with friends or family members, consider the age and health of everyone in the tub, and set a temperature that’s appropriate for everyone in the group.
How long will it take for my spa to warm up when I’m ready to use it?
After filling your spa for the first time, allow 18 to 24 hours for your water to reach a temperature of 100°F (38°C).
After your initial setup is complete and you’re enjoying your routine of daily hot tub use, you’ll want to make sure your hot tub is always ready to deliver the ultimate in hydrotherapy. To do so, simply set your spa to your ideal temperature, then close it up and leave the thermostat set at that level. Hot Spring spas feature insulated cabinets, custom-fitted covers, and energy-efficient circulation pumps that work together to maintain a steady temperature while conserving energy.
How much will my utility bill increase?
Utility costs vary depending on model and usage, but you can be confident your Hot Spring spa is built to be energy efficient. In fact, all models are certified to the California Energy Commission (CEC) requirements. California sets the standard for energy-efficient hot tubs, so you can have peace of mind knowing that your spa is designed to keep operating costs low no matter where you live.
When should I change my normal temperature setting?
While a “set it and forget it” approach is recommended for convenience, energy efficiency, and the longevity of your spa, here are some times when you should consider dropping water temperature by a few degrees:
- When you’re exercising in your hot tub - doing stretches or yoga.
- When the outdoor temperature is high, or if you yourself are overheated from exercise or illness.
- If there will be others in the tub who require a lower temperature.
What temperature is best for hydrotherapy for arthritis relief?
A hot tub soak is good for you! The heat of your hot tub improves blood flow and can help improve joint flexibility and can provide relief from arthritis pain. There are even recommended hot tub stretches and water exercises for arthritis relief. You can experience these benefits at relatively low temperatures - so set your spa at around 100° to start, and raise it to suit your comfort level.
Can I use my hot tub to cool off?
Your spa is bound to be a popular hangout during warm summer months if you set the temperature to below average body temperature. Because your Hot Spring spa is designed to retain heat when covered, be sure to leave your cover open as you allow the temperature to drop to a cooler temperature. You can also lower the water temperature quickly by using a system such as CoolZone™. CoolZone lets friends and family cool off during the day, then quickly warms your spa water up so you can take a comfortable soak before bed.
