The X500 is the 15-foot single-tank swim spa from the X-Series by Endless Pools, the swim-spa specialist brand within the Watkins Wellness family. Built around SwimCross® jetted swim-current technology with a twin 2.5 HP pump architecture, the X500 is positioned for total-body fitness and fun: swim, cross-train, or relax with multi-speed currents, spa jets, and attachable fitness gear. The X500 is sold and serviced through Seven Seas Pools & Spas.
230 V / 60 amp / 60 Hz (GFCI sub-panel included)
15' × 89" × 50" tall (457 × 226 × 127 cm)
27 hydromassage jets with 3 contoured seats
UVC + CD Ozone dual-layer protection
The X500 fits households that want a mid-tier 15-foot swim spa with cross-training-focused current architecture, between the entry-level R500 and the premium lap-swim E500. The twin 2.5 HP pump architecture is the X-Series signature, using two coordinated pumps to drive a multi-speed current optimized for cross-training, walking-in-place, aquatic strength work, and recreational swim.

The X500 is the most compact X-Series footprint, pairing a 12-foot shell with a 40-inch swim depth for family exercise and play.
The X500 uses Endless Pools' SwimCross® Technology, the recreation-focused jetted current that powers the X-Series. The current is smooth and adjustable, tuned for all-level fitness and uninterrupted recreational swims.
| Swim Current Specification | Value |
|---|---|
| System | SwimCross® Technology |
| Current character | Smooth, adjustable, recreation-tier jetted current |

| Hydromassage Seats | 2 contoured spa seats |

The hydromassage zone is the recovery side of the soak: exercise, play, then unwind in the contoured seats with the jets engaged.
The X500 uses UVC + CD Ozone dual-layer protection sanitization, the standard water care across the X-Series. The UVC + CD Ozone dual-layer protection system oxidizes contaminants without the dual-layer UV-C tier found on the E-Series and X-Series spas.

The X500 includes three hydromassage seats, twin 2.5 HP SwimCross® current architecture, 27 jets, and a 15-foot single-tank layout built for cross-training and recovery.
There is no underwater treadmill option for the X-Series. Buyers customize the X500 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 X500 product page. Seven Seas walks every X500 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 X500 is offered in a single standard configuration. The full specification set documented above, 12-foot length, 40-inch swim depth, 27 jets, 2 hydromassage seats plus shallow entry zone, SwimCross® jetted current, UVC + CD Ozone dual-layer protection water care, 230 V / 30 amp standard service, applies to every X500 sold. There is no underwater treadmill option for the X-Series (treadmill availability is reserved for the E500, E550, E700, and E2000 in the E-Series). Buyers customize the X500 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 X500 follow a three-mode rhythm: swim or workout (SwimCross® 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 X500 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.
X-Series, SwimCross®, recreation- and family-focused. The X500 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 X-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 X500 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 SwimCross® 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 X500 standard install requires a 230 V / 60 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 14,720 lbs filled, or a deck engineered for the same load
Service clearance on at least one side for equipment access
12-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 SwimCross® current controls. The X500's 12-foot length and 14,720-lb filled weight make it one of the easier swim-spa installs in the category; most retrofit yards accommodate it without specialized craning. The Seven Seas team handles the logistics so the buyer doesn't have to.
The UVC + CD Ozone dual-layer protection 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 200 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 X500 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.
SwimCross® 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 X500 is 12 feet long, 89 inches wide, and 50 inches tall with a 40-inch swim depth. Filled, it weighs 18,200 lbs (8,255 kg), so site prep needs a level reinforced concrete pad or an engineered deck.
The X500 ships with a standard 230 V / 60 amp / 60 Hz electrical service. A 230 V / 60 amp upgrade is optional, and the spa includes a GFCI sub-panel.
The X500 uses UVC + CD Ozone dual-layer protection sanitization as standard. The system is APSP 14 compliant and CEC certified.
No. Underwater treadmill availability is reserved for the E-Series. The X500 is a single-configuration spa focused on SwimCross® jetted swim, hydromassage, and family use.
Endless Pools does not publish a single warranty page on the X500 product page. Seven Seas walks every X500 buyer through the current Endless Pools warranty document at the time of sale.
Standard X500 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.
