You’ll probably spend more on your daily cup of coffee. Hot tub costs can differ based on climate, model, and usage, but typical monthly electrical costs are in the $10 to $20 range. Plus, when you buy a hot tub that uses quality materials and the latest technology, you’ll save on maintenance, energy costs, and the expense of replacing costly salt water hot tub systems in the long run.
The prices shown on this website reflect MSRP, but your local dealer offers different pricing, packages, and promotions based on bulk buys and often pass the savings on to you. Visit your Jacuzzi® Hot Tubs dealer for the most current deals.
You need to have a proper foundation and meet any electrical requirements. Your Jacuzzi® authorized dealer will walk you through the process and connect you with an expert to install your hot tub. See what to expect in the video below.
Here are a few things you can do to ensure installation and setup goes smoothly:
- Check your HOA, city, and county rules and obtain any permits necessary.
- Decide on a foundation that supports your hot tub, ensures proper drainage, and looks good.
- Choose the perfect location, and remember to leave room for maintenance and entertaining.
- Keep our Pre-Installation Checklist handy for reference.
Thanks to advanced water management and filtration systems, hot tub maintenance is easier than ever—routine tasks take just a few minutes a week. When we surveyed current owners about basic hot tub maintenance, nearly all of them said it was easy! Here’s a quick summary of how to maintain a hot tub:
Water: Check the chemical levels weekly with test strips and adjust them by adding the appropriate products per your owner’s manual—no chemistry expertise necessary. Drain and refills are only needed every 3–4 months, based on use.
Filter: Rinse and clean filters with a garden hose or filter flosser once per month. Replace as needed.
Cover: Use a cover to help keep your water warm and clean. It will protect your hot tub from debris and weather elements.
