Frequently asked questions

A swim spa is a long, rectangular spa that combines the swimming benefits of a pool with the hydrotherapy and convenience of a hot tub. A powerful current at one end lets you swim continuously in place — no wall to flip off, no laps to count — while the other end functions as a traditional hot tub with jets and seating. Swim spas are popular because they deliver year-round swimming, fitness, hydrotherapy, and recovery in a fraction of a pool’s footprint and cost.
A swim spa offers most of what a pool does at a fraction of the cost, footprint, and maintenance burden. Pools require excavation, permits, decking, separate heaters, and seasonal opening and closing. A swim spa installs above-ground in a fraction of the time, runs year-round (including in cold climates), uses far less water, and combines swimming, hydrotherapy, and hot tub functions in a single unit. For most homeowners, a swim spa delivers the lifestyle benefits of a pool without the ownership burden.
Whisper Outdoor swim spas typically range from around $15,000 for compact single-zone models to $30,000+ for premium dual-zone units with full swim currents, hydrotherapy seats, and cold-zone capability. Because we manufacture our swim spas in Tennessee and sell factory-direct through our own showrooms, our pricing typically runs significantly below comparably equipped swim spas sold through traditional dealer networks. Most swim spa buyers finance through one of our three financing paths to spread the cost into manageable monthly payments.
Yes — and that’s one of the main reasons people choose swim spas over pools. Swim spas are insulated, heated, and built for year-round use in any climate. The water stays at your preferred temperature 365 days a year, so you can swim, do hydrotherapy, or relax whether it’s 90 degrees or below freezing outside. Many owners report using their swim spa more often in winter than summer.
Swim spas typically range from about 12 feet to 21 feet in length. Shorter models (12–14 ft) are ideal for fitness swimming, hydrotherapy, and households with limited space. Mid-size models (14–17 ft) offer more swim distance and often include separate hot tub seating. Larger dual-zone models (17–19+ ft) feature a dedicated swim zone and a separate hot tub zone, ideal for households who want a complete wellness solution.
Every Whisper Outdoor swim spa is designed and manufactured in Tennessee, USA — in the same facilities where we build our hot tubs, golf carts, and UTVs. American materials, American labor, and direct factory oversight on every unit. Building in-house gives us complete control over quality and means warranty service goes directly through the manufacturer, not a third-party dealer.
Swim spa delivery is more involved than a hot tub but far simpler than building a pool. Most swim spas install above-ground on a level concrete pad, deck, or properly prepared base — no excavation required. Our team coordinates delivery directly to your home, and your local Whisper Outdoor showroom can help connect you with installation resources in your area. A licensed electrician will be needed for the 220V hookup; the rest is typically straightforward.
Because swim spas are a larger purchase, our extended financing terms make a meaningful difference. We offer three financing paths: in-house financing with a 100% approval rate and terms up to 84 months — meaningful for higher-ticket purchases — plus third-party financing through Wells Fargo and promotional 0% APR offers when available. Most applicants receive a decision within 1 business day of applying online.
