The R500 is the 15-foot value-tier swim spa from the R-Series by Endless Pools, the swim-spa specialist brand within the Watkins Wellness family. The R500 is the most accessibly priced 15-foot swim spa in the catalog, with more room for family use than the 12-foot R-Series spas, pairing a RecSport® jetted swim current with three contoured hydromassage seats at a 40-inch swim depth in a 15-foot footprint. It is sold and serviced through Seven Seas Pools & Spas.
230 V / 30 amp / 60 Hz standard (field adjustable to 60 amp, GFCI sub-panel included)
15' × 89" × 50" tall (457 × 226 × 127 cm)
27 hydromassage jets with 2 contoured seats plus shallow entry zone
CD Ozone
The R500 fits households that want a 15-foot family swim spa with adjustable RecSport® resistance for gentle exercise plus hydromassage soaking, at the most accessible 15-foot footprint Endless Pools makes. The 15-foot length provides more room for family fun versus the 12-foot R200 and R220, while keeping the simpler RecSport® drivetrain and 230 V / 30 amp standard service of the R-Series.

The R500 is the most compact R-Series footprint, pairing a 12-foot shell with a 40-inch swim depth for family exercise and play.
The R500 uses Endless Pools' RecSport® Technology, the recreation-focused jetted current that powers the R-Series. The current is smooth and adjustable, tuned for all-level fitness and uninterrupted recreational swims.

|---|---|
| System | RecSport® Technology |
| Current character | Smooth, adjustable, recreation-tier jetted current |

The R500 includes two hydromassage seats, the RecSport® adjustable jetted current, 27 jets, and a shallow entry zone for active families with young children.
There is no underwater treadmill option for the R-Series. Buyers customize the R500 through shell and cabinet finishes plus accessories such as Aquabike, floor mirror, Bluetooth® Sound System, Gecko® In.Touch Mobile & WiFi Kit, surface kits, and cover-lifter options.
Endless Pools does not publish a single warranty page on the R500 product page. Seven Seas walks every R500 buyer through the current Endless Pools warranty document at the time of sale, the structure typically includes a multi-year shell warranty plus shorter terms on components and labor. Ask for the latest warranty PDF when you visit a showroom.
The R500 is offered in a single standard configuration. The full specification set documented above, 15-foot length, 40-inch swim depth, 27 jets, 2 hydromassage seats plus shallow entry zone, RecSport® jetted current, CD Ozone water care, 230 V / 30 amp standard service, applies to every R500 sold. There is no underwater treadmill option for the R-Series (treadmill availability is reserved for the E500, E550, E700, and E2000 in the E-Series). Buyers customize the R500 through finish selection (shell + cabinet color) and the optional accessory set: Aquabike, floor mirror, Bluetooth® Sound System, Gecko® In.Touch Mobile & WiFi Kit, Endless Pools Surface Kits, and cover-lifter options (Covercradle® Lifter, Easy Slider Cover Mount, Uprite™ Lifter Set, Watkins Covers).
Sessions in the R500 follow a three-mode rhythm: swim or workout (RecSport® current on, doing stride drills, water aerobics, or recreational lap swimming against the adjustable jetted current); family play (current off or low, kids in the shallow entry zone, adults in the deeper 40-inch swim zone); and recover (current off, hydromassage seats engaged, soaking in the contoured 2-seat hydrotherapy zone with 27 jets). Gentle exercise, hydromassage recovery, and family time, the spa is built around family-shared use first, with workout function layered on top.
Because the R500 is a single-tank spa (the entire 1,335-gallon volume runs at one temperature), if you want a colder swim zone simultaneous with a hot-tub-temperature soak, evaluate the E2000 or X2000 dual-temperature options.

Endless Pools structures its lineup around three series, each tuned to a different swimming style.
R-Series, RecSport®, recreation- and family-focused. The R500 lives here with a smaller pump, wood frame with thermoformed ABS base pan, and simpler current system. Best for recreational swim, kids' play, and lighter exercise.
View R-Series Swim Spas
E-Series, Hydrodrive™ Technology premium adjustable current with race-pace ceiling. Best for serious lap swimmers and households that want adjustable pace control across a wide range of swim abilities.
View E-Series Swim Spas
X-Series, SwimCross®, cross-training focused. Twin 2.5 HP pump architecture, generally similar footprint to E-Series. Best if you want a cross-trainer current emphasizing aerobic workouts.
View X-Series Swim SpasIf you're cross-shopping the traditional hot tub category instead of swim spas, Seven Seas also carries the Caldera Spas and Hot Spring Spas lineups, both Watkins Wellness brands focused on hydrotherapy without the swim function. The team can walk you through swim-spa-vs-hot-tub at any showroom.
The R500 is part of the lineup carried by Seven Seas Pools & Spas. Call ahead or stop by your local showroom to confirm current showroom availability. Visiting a showroom is the fastest way to feel the RecSport® current at multiple settings, sit in the hydromassage seats, see the shallow entry zone in person, and evaluate both Alpine White and Ice Gray shell finishes.
The R500 standard install requires a 230 V / 30 amp / 60 Hz circuit wired to a GFCI sub-panel, the sub-panel ships with the spa. A 60-amp upgrade circuit is optional.
Site requirements:
Level reinforced concrete pad rated for the spa's filled weight, or a deck engineered for the same load
Service clearance on at least one side for equipment access
15-foot minimum length for the spa shell, plus delivery / craning clearance
Seven Seas Pools & Spas coordinates the full delivery and installation flow: site assessment, electrical coordination with a licensed electrician, delivery scheduling, GFCI sub-panel mounting, post-fill water balancing, and a hands-on walkthrough of the RecSport® current controls. The R500's 15-foot length is the same as the E500, E550, and X500; most yards that accept any 15-foot Endless Pools spa accept the R500. The Seven Seas team handles the logistics so the buyer doesn't have to.
The CD Ozone sanitization keeps weekly water-care simple, using corona-discharge ozone to oxidize waterborne contaminants without dosing the spa with manual chlorine for daily upkeep. The system is APSP 14 compliant and CEC certified for energy efficiency.
Filter cleaning runs on a monthly cadence for the 100 sq. ft. cartridge, see the swim spa filter care guide in the owners area. Endless Pools recommends a full drain-and-refill on the standard swim-spa cycle (typically every 3-6 months depending on use intensity); Seven Seas walks every owner through the schedule during the post-delivery handoff.
The R500 is best for active families who want gentle exercise, hydromassage, and shared family time in one footprint at an approachable price tier. The shallow entry zone makes it especially friendly for households with young children.
RecSport® Technology drives a smooth, adjustable jetted current using a 2.5 HP pump. It is a different drivetrain from the E-Series Hydrodrive™ system, which is positioned for competitive lap-swim pacing.
The R500 is 12 feet long, 89 inches wide, and 50 inches tall with a 40-inch swim depth. Filled, it weighs , so site prep needs a level reinforced concrete pad or an engineered deck.
The R500 ships with a standard 230 V / 30 amp / 60 Hz electrical service. A 230 V / 60 amp upgrade is optional, and the spa includes a GFCI sub-panel.
The R500 uses CD Ozone sanitization as standard. The system is APSP 14 compliant and CEC certified.
No. Underwater treadmill availability is reserved for the E-Series. The R500 is a single-configuration spa focused on RecSport® jetted swim, hydromassage, and family use.
Endless Pools does not publish a single warranty page on the R500 product page. Seven Seas walks every R500 buyer through the current Endless Pools warranty document at the time of sale.
Standard R500 delivery from Seven Seas runs 6-12 weeks from order, depending on current Endless Pools production lead times and finish selection. Inventory in stock at Seven Seas locations can ship faster.
Yes, with proper ventilation and drainage. Indoor swim-spa installations require an electrician-approved 230 V / 30 amp feed, a moisture-resistant floor structure rated for 14,720+ lbs filled, active humidity ventilation, and code-compliant drainage.
