Product Highlights
Ergonomic Recovery Lounger
A full-length reclined seat positions cascading jets along the neck, shoulders, back, calves, and hamstrings — supporting a complete upper and lower body session in a single position.
Spinal Alignment Bucket Seats
Five deep contoured seats feature directional jets that follow the natural curvature of the spine, helping to ease chronic stiffness and tension in the back and shoulders.
Intense Foot Blasters
High-volume foot jets positioned in the spacious footwell stimulate circulation from the ground up, providing targeted relief to the feet and lower legs.
Deep Blue Sound System
Bluetooth-connected surface speakers and a dedicated subwoofer deliver clear, full-range audio directly to the water — stream music, podcasts, or ambient sound without additional hardware.
Spectra LED Lighting & Laminar Water Feature
Multi-color LED lighting illuminates the perimeter, footwell, cup holders, and exterior cabinet. A whisper-quiet laminar water feature adds a calming visual element to evening sessions.
Eco Smart73 Energy Efficiency
Triple-layer reflective foam insulation recycles motor heat to maintain water temperature. Pairing with the Earthspas Air Source Heat Pump can reduce energy consumption by up to 73%.
