In 2026, a quality swim spa costs $25,000–$60,000, with premium models like the Wellis W-Flow series currently $31,995–$36,995 at dealer pricing. Add $2,000–$5,000 for site prep and electrical, and $40–$80 per month to run. Here’s the complete cost breakdown for New England buyers.
How much does a swim spa cost by tier?
- Entry level ($15,000–$25,000): shorter tanks, simpler jet-driven swim currents. Fine for exercise walking and family soaking; competitive swimmers will outgrow the current.
- Premium ($25,000–$45,000): the sweet spot. True counter-current systems, full insulation, dual-zone options. Our Amazon W-Flow — nearly 18 feet with programmable workout modes — is currently $31,995 (reg. $44,999).
- Flagship ($35,000–$60,000+): longer swim lanes, more hydrotherapy seating. The Rio Grande W-Flow — 236 inches, 40 massage jets, 1 lounge + 5 seats — is currently $36,995 (reg. $48,999). The Danube RiverJet rounds out the Wellis line.
What do site prep and electrical cost?
Plan for a level concrete pad (roughly $1,000–$2,500 at swim spa size) and a dedicated 220V/50-60A circuit from a licensed electrician ($1,000–$2,500 depending on panel distance). Crane placement, when a site needs it, adds $500–$1,500. Our site preparation guide covers the full checklist.
How much does a swim spa cost to run monthly?
A well-insulated swim spa in New England typically runs $40–$80 per month in electricity, depending on set temperature and season, plus $20–$35 in water care chemicals. Wellis’s LIFE insulation and thermal covers are why the premium tiers cost less monthly than bargain tanks twice a year — the same physics as hot tubs, explained in our running-cost guide.
Is a swim spa cheaper than a pool?
Dramatically. An inground pool in NH/MA runs $60,000–$120,000+ built, then closes for two-thirds of the year. A swim spa is a third to half the upfront cost and swims 365 days. The full comparison is in Swim Spa vs. Pool.
How do you get the best price?
Buy during dealer pricing events and ask about in-stock units. Our current Wellis swim spa markdowns are up to about $12,000 off list. As an authorized dealer, every swim spa we sell includes up to a 5-year warranty on parts and labor and local service from our Hampton Falls team.
Frequently asked questions
What’s the cheapest way to own a swim spa?
A premium in-stock model at event pricing almost always beats an entry-level tank at list price — you get better insulation (lower bills) and a real warranty for similar money.
Do swim spas hold their value?
Quality brands hold value well because they’re movable and in demand year-round in cold climates, unlike pools which are fixed investments.
How long do swim spas last?
15–20 years for engineered-frame models — the same construction logic as hot tubs, covered in How Long Do Hot Tubs Last?
