Both are 6-person, 240V premium spas from the AquaLife Harmony LS series. The single most important difference is seating style: the Narada Harmony LS is a non-lounger bench spa built for equal group therapy. The Osprey Harmony LS includes a full-body lounger seat built for one person to recline while others sit upright.
- The Narada Harmony LS has 38 jets / 90 ports and twin 5-HP pumps — every seat gets equal pressure.
- The Osprey Harmony LS has 50 jets / 86 ports and a blower-enhanced pump for deeper full-body massage at the lounger.
- Both share the same 85×85×36-inch square footprint, 700 lb dry weight, and 240V / 40A electrical requirement.
- Both include Bluetooth stereo with subwoofer, built-in ozone, LED lighting, and a tapered locking insulated cover.
- Choose the Narada Harmony for equal group therapy at every seat. Choose the Osprey Harmony for full-body lounger therapy plus group use.

How Many People Fit? Seating Capacity Explained
Both spas seat 6 adults. The Narada Harmony can stretch to 7 in bench configuration. The Osprey Harmony dedicates one position to a full-length lounger — giving 5 upright bench users and 1 reclining user at full capacity.
The Narada Harmony LS is a pure bench-style spa. All seats face inward with equal jet coverage. Nobody occupies more space than anyone else. At maximum capacity, up to 7 adults can fit — a real advantage for larger families and social gatherings.
The Osprey Harmony LS dedicates one seat to a full-body lounger. When occupied, 5 users sit upright in bench positions and 1 user reclines fully. When the lounger is empty, any user can claim it. This suits households where soaking habits vary between sessions.
Choose the Narada Harmony LS if:
- All 6 to 7 people soak together regularly and want equal coverage from every seat
- No single person should have a dominant “premium seat” advantage
- Group entertaining is the primary use case
Choose the Osprey Harmony LS if:
- One person regularly soaks alone in a full-body reclining position
- A couple soaks where one prefers lounging and the other prefers upright seating
- Full-body daily therapy is the priority alongside occasional group use
Lounger vs. Non-Lounger: The Decision That Defines These Two Spas
The Narada Harmony LS has no lounger — every seat is a bench seat. The Osprey Harmony LS includes one full-body lounger. This single difference defines who each spa is built for more than any other specification.
A lounger positions your body horizontally in the water. Jets target your lower back, calves, hamstrings, and feet simultaneously — the closest a home spa comes to a full-table massage experience.
A bench seat positions you upright. Jets focus on the mid-back, upper back, and shoulder zones. For groups, bench seating means everyone receives comparable coverage — no secondary position, no compromised seat.
In the Narada Harmony LS, all 6 seats are bench seats. Every soaker gets the same upright massage. In the Osprey Harmony LS, one of those 6 positions becomes a full-length lounger — that user gets full-body coverage while the remaining 5 receive upper-body bench therapy.
One practical note: lighter users under 130 lbs may experience buoyancy in the Osprey Harmony lounger. Jet pressure can cause floating rather than grounded contact with the jets. For those users, the bench seats provide more stable massage delivery.
What Kind of Massage Does Each Spa Deliver?
The Narada Harmony LS distributes therapy equally across all 6 positions via twin 5-HP pumps. The Osprey Harmony LS concentrates additional power at the lounger through a blower-enhanced system — and adds full-spa effervescence for every user.
Narada Harmony LS therapy profile:
- Twin 5-HP pumps (1-speed + 2-speed) maintain consistent high-pressure flow across all bench seats simultaneously
- 38 stainless steel jets across 90 ports deliver broad, distributed coverage to every user at once
- Backlit waterfall adds passive neck and shoulder therapy cascading over the spa rim
- Diverter valves let each user redirect pressure to preferred zones during the soak
- All 6 seat positions receive equivalent hydrotherapy — no compromised positions in the group
Osprey Harmony LS therapy profile:
- Blower pump-enhanced system creates effervescent, bubblier water movement across the entire spa shell
- 50 stainless steel jets across 86 ports — denser jet layout per seat than the Narada
- Lounger position delivers targeted deep-tissue coverage across the full body: back, hamstrings, calves, and feet
- Bench users receive strong upper-body and shoulder zone coverage from the remaining jets
- Upgraded ozonator maintains cleaner water with fewer added chemicals than the Narada’s standard ozonator
The Osprey’s blower pump benefits every user, not just the lounger occupant. All 6 soakers experience more enveloping, effervescent water movement throughout the session.
Size, Installation, and Backyard Fit
The Narada Harmony LS and Osprey Harmony LS are physically identical. Same footprint, same height, same weight, same electrical requirement. Your installation plan is exactly the same for both models.
| Measurement | Narada Harmony LS | Osprey Harmony LS |
|---|---|---|
| Footprint | 85″ × 85″ (7.1 ft square) | 85″ × 85″ (7.1 ft square) |
| Height | 36 inches | 36 inches |
| Dry Weight | 700 lbs | 700 lbs |
| Filled Weight (est.) | ~4,200 lbs | ~4,200 lbs |
| Electrical Requirement | 240V / 40A hardwired | 240V / 40A hardwired |
| Electrician Required | Yes | Yes |
Both require a licensed electrician for 240V/40A hardwired installation. Both require a reinforced concrete slab or structural deck rated for approximately 4,200 lbs when fully loaded. Because specs are identical, whichever model you choose has no impact on installation cost, deck requirements, or backyard space.
The Narada vs Osprey decision is purely about therapy preference and seating style — not footprint, weight, or electrical complexity.
Energy Efficiency and Running Costs
Running costs are identical for both models. Same voltage, same heater, same CEC compliance rating, and the same three programmable energy modes.
| Energy Factor | Narada Harmony LS | Osprey Harmony LS |
|---|---|---|
| Voltage | 240V / 40A | 240V / 40A |
| Heater | 4kW stainless steel | 4kW stainless steel |
| Energy Modes | Standard / Economy / Sleep | Standard / Economy / Sleep |
| CEC Compliant | Yes | Yes |
| Ozone System | Standard ozonator | Upgraded ozonator |
Both models meet California Energy Commission (CEC) standards — an independent certification for energy efficiency. Three programmable modes let you balance performance and running costs based on how often you soak each week.
The Osprey Harmony’s upgraded ozonator provides a small long-term advantage. A more effective ozone system reduces how much chlorine or bromine you need to add monthly — minor savings that compound over years of ownership.
Features: What Does Each Model Include?
Both models are equipped at the same premium level. The key differences are the Narada’s backlit waterfall versus the Osprey’s ASTM-certified safety cover and blower pump system.
| Feature | Narada Harmony LS | Osprey Harmony LS |
|---|---|---|
| Bluetooth Stereo | Yes — 2 speakers + subwoofer | Yes — 2 speakers + subwoofer |
| Backlit Waterfall | Yes | No |
| Underwater LED | Yes | Yes — programmable multicolor |
| Blower Pump | No | Yes — full-spa effervescence |
| Ozone Purification | Standard | Upgraded |
| ASTM-Certified Cover | No | Yes |
| Ergonomic Headrests | Yes | Yes |
| Cup Holders | Yes | Yes |
| Diverter Valves | Yes | Yes |
| Digital Control Panel | Yes | Yes |
The Narada Harmony’s backlit waterfall is a meaningful ambiance feature — illuminated water cascading at the spa rim that also delivers passive neck and shoulder coverage during the soak.
The Osprey Harmony’s ASTM-certified cover meets independently verified load-bearing standards. This matters for households with children or regions with heavy snow accumulation. The Narada’s tapered locking cover is weather-rated and solid, but does not carry ASTM certification.
Daily Use vs. Weekend Group Use
Both models are built for serious daily use. The Narada suits households where the full group soaks together most evenings. The Osprey suits households where one person soaks alone daily and the full group joins on weekends.
Narada Harmony LS — daily group routine:
- Every seat delivers equal therapy — ideal when multiple family members soak together each evening
- Backlit waterfall and Bluetooth audio create a consistent social atmosphere
- Non-lounger layout means no competition for the best seat in the spa
- Economy mode keeps running costs low during frequent daily sessions
Osprey Harmony LS — solo daily and group weekend use:
- Lounger position suits one person soaking alone after work for back pain or muscle recovery
- Blower-enhanced system makes solo soaks more immersive and full-bodied
- On weekends, bench seats and lounger accommodate the full 6-person group comfortably
- ASTM-certified cover adds safety and durability for families with children or in harsh climates
