Cal Spas Costa EC-740L Hot Tub

Front-facing top-down view of the Cal Spas Costa EC-740L Hot Tub shown on a transparent background, featuring a square 7 ft acrylic shell with a spacious six-person layout that includes one full-length lounger and multiple upright seating positions arranged around the perimeter. The glossy white interior reveals the elongated lounger positioned along one side, contoured to support the head, back, hips, and legs, with a series of precisely placed Velocity jets running from the upper back down through the calves and feet for full-body hydrotherapy. Opposite and adjacent to the lounger, several deep bucket-style seats are moulded into the shell, each with clusters of stainless steel Velocity jets positioned at varying heights to target the upper back, mid-back, and lower lumbar regions. Smaller jets are integrated along the sidewalls near hip and thigh level, creating layered massage zones across each seat. A circular footwell sits centrally at the bottom of the spa, surrounded by additional jets aimed inward to provide shared foot and leg massage for multiple users. Along the upper rim, multiple black cushioned headrests are evenly spaced above key seating positions, providing neck and head support. Air control valves and jet selector dials are embedded along the top edge, allowing precise adjustment of water flow and pressure. A digital control panel is inset into the top lip of the spa near one corner, positioned within easy reach for adjusting temperature, jet intensity, and lighting functions. The shell’s smooth contours and ergonomic shaping emphasise comfort and efficient space usage, while the full complement of 40 Velocity jets is distributed throughout the lounger, seats, and footwell to deliver comprehensive hydrotherapy coverage.
