Quick Answer: Hot Tub or Swim Spa?
Choose a hot tub if your priority is relaxation, hydrotherapy and time with family and friends in a compact footprint (about 5½ to 8½ feet across, from $9,274 Total MSRP). Choose a swim spa if you want to swim and exercise at home as well as relax, and you have room for a unit about 12 to 18½ feet long (from $33,232 Total MSRP).

What a Hot Tub Does Best
A hot tub is built for hydrotherapy. Powerful, targeted jets massage your back, shoulders, legs and feet while warm water helps you relax and ease sore muscles and stiff joints. Many owners say a nightly soak helps them unwind and sleep better. Hot tubs fit almost any backyard, many models plug into a standard outlet, and they’re the more affordable choice to buy and install.
- Full-body hydromassage and dedicated therapy seats
- Lounge or open seating for 2 to 7 people (see our 4-person and lounger guides)
- Fits smaller yards and patios
- Lower purchase, installation and operating costs
What a Swim Spa Does Best
A swim spa is a hybrid of a pool and a hot tub. An adjustable current lets you swim, jog or row in place without turning for laps, and the buoyancy of the water makes it a low-impact workout. When you’re done, the seats and jets turn it into a place to relax. It’s a popular alternative to an in-ground pool, taking up far less of your yard.
- Swim, jog, row and do water aerobics at home
- Adjust the current for an easy float or a challenging workout
- Room for kids to play and families to gather
- Seats and jets for relaxing after a workout
Want both?
Dual-temperature swim spas like the Jacuzzi® J-19DT™ have a separate hot tub area kept at its own temperature, so you can swim in cooler water and soak in hot water in one unit. All three Sundance® swim spas include a lounge seat for relaxing after a workout.
4 Questions to Help You Decide
1. What are your goals?
If relaxing, easing aches and socializing matter most, a hot tub is the natural fit. If you want to improve fitness, swim laps or give the kids a pool, look at a swim spa.
2. How much space do you have?
Measure your yard, then add room to walk around, open the cover and get the unit in. Hot tubs fit most patios; swim spas need a long, level area and often crane access.
3. What is your budget?
Swim spas cost more to buy and usually more to install. Don’t forget the foundation, electrical and delivery. Financing is available up to 72 months OAC. See terms.
4. Who will use it, and how?
Think about how many people will use it at once, and whether they’ll mostly soak or mostly exercise. A wet test in both is the best way to decide.
