Get PricingFind the Right Hot Tub
These six questions are a great place to start when choosing a hot tub. Answer them and you’ll know which models fit your home and needs.
How many people will use it?
Choose based on a normal week. This one answer narrows the field more than any other.
What do you want it to help with?
Back pain, arthritis, stress relief, better sleep. Each one has a straight, sourced answer in Hydrotherapy 101.
Lounge seat, or open seating?
A lounge lets one person recline full-length. Open seating fits more people. Neither is better, and it’s the main reason to try a few spas before choosing.
Which features matter most?
Massage systems, water care, lighting, audio, smart controls. Jet count is marketing; jet design is therapy.
Do you want salt water care?
Softer-feeling water, far less dosing, and up to a year between water changes. It’s the biggest what-is-it-like-to-own decision.
What’s your timeframe?
Ready for numbers? Get pricing on the models you’re weighing. Still researching? Take the full guide with you. Either answer is a good answer.
FreshWater® Salt System and FreshWater® IQ
Salt-ready Hot Spring® and Caldera® spas turn a small amount of dissolved salt into chlorine automatically, so you add fewer chemicals and spend less time on maintenance.
FreshWater® Salt System
A titanium cartridge converts dissolved salt into chlorine as the water circulates, and the cartridge is owner-replaceable about every four months. Included on the Highlife® and Utopia® collections, and salt-ready on Limelight®, Hot Spot®, Paradise® and Vacanza®. Learn more about the Salt System.
FreshWater® IQ
FreshWater IQ adds hourly water testing and one-touch dosing on top of the salt system. The spa tests itself, shows you what it needs on the control panel or app, and corrects pH at a tap. Available on 2024-and-newer Highlife®, Limelight®, Utopia® and Paradise® models. Learn more about FreshWater IQ.
What about plug-and-play spas?
Freeflow® and Fantasy™ spas use FROG® cartridge sanitizing instead: pre-filled cartridges that keep chlorine steady without daily measuring.
Can You Plug a Hot Tub Into a Regular Outlet?
Yes. Plug-and-play spas come with a GFCI power cord that plugs into a 115V outlet, with no 230V hardwiring needed: fill it, plug it in and enjoy. That’s the Freeflow® collection from Hot Spring and the Fantasy™ series from Caldera, and it’s the easiest way to get into a quality spa.
The trade-off is that the jets and heater share the circuit, so on a cold night with the jets wide open the water can cool a touch. Full-size spas run on a dedicated 230V circuit and hold full heat with everything running. In Tennessee you’ll soak year-round, so if long winter soaks with strong jets are the goal, a 230V model is worth the electrical work.

Frequently Asked Questions
Here are answers to the hot tub questions we hear most. The Learning Center covers each one in depth.
How much does a hot tub cost?
Published price ranges run by tier, and our cost guide walks them with real numbers. We don’t price a specific model sight-unseen because your real cost depends on the model, the features you choose, and what your site needs. Get pricing and we’ll quote your exact setup.
Will it cost a fortune to heat in winter?
Cold climates cost more, but high-density foam or FiberCor® insulation, an insulated base pan, recycled heat, and a tight cover keep it efficient. The cover is the biggest daily factor.
Can I plug a hot tub into a regular outlet?
Yes. Freeflow® and Fantasy™ plug-and-play spas come with a GFCI power cord that plugs into a standard 115V outlet. Full-size spas run on a dedicated 230V circuit installed by a licensed electrician. Our 110V vs. 240V guide walks the trade-offs.
What size hot tub do I need?
2 to 3 seats fits couples and small spaces, 4 to 5 fits most families, and 6 to 8 is built for entertaining. Bigger uses more energy and chemicals, so choose based on a normal week.
