Cal Spas El Grande EC-1166EX Hot Tub

Top-down view of the Cal Spas El Grande EC-1166EX Hot Tub shown on a transparent background, revealing a large rectangular interior designed for open, multi-user seating with a central recessed footwell. The glossy white acrylic shell features continuous perimeter bench seating wrapping around all four sides, allowing flexible positioning for multiple bathers. At the top centre wall, a horizontal control and display panel is встроed into a raised housing, with a small rectangular label and indicator markings positioned just below it. Directly beneath this panel, a vertical cluster of stainless steel hydrotherapy jets is arranged in a symmetrical pattern targeting the upper back and spine area. On both the left and right interior walls, dense arrays of stainless steel jets are distributed across multiple seating zones, including upper back, mid-back, and hip-level placements, forming mirrored massage stations on either side. Additional jet groupings are positioned along the lower left and lower right seating areas, creating full-body hydrotherapy coverage around the entire perimeter. The central footwell is recessed and smooth, with two circular suction fittings visible near the lower edge of the footwell floor. Along the bottom interior wall, a wide step entry ledge spans horizontally, providing a stable access point into the spa. Integrated into this lower section are multiple fittings including a central light or drain fitting and additional jet or suction components spaced evenly across the ledge. Large circular intake or filter housings are positioned in the lower left and lower right corners, each recessed into rounded compartments. A small blue floating component or accessory is visible near the lower left intake housing. At the upper left rim, a circular control dial or air control valve is embedded into the shell, while additional round fittings and controls are positioned along the right rim. The overall layout emphasises the El Grande EC-1166EX’s party-ready design, with expansive bench seating, evenly distributed jet zones for rotating hydrotherapy positions, integrated lighting along the perimeter, and built-in controls for WiFi connectivity and the Freedom Sound System.
