Relxtime Proseries 6-person Upgraded Square Inflatable Hot Tub – 73×73 Inch Portable Spa With 15-piece Pro Kit, Grey Reinforced Design For Ultimate

The Relxtime Proseries 6-Person Upgraded Square Inflatable Hot Tub delivers a premium, spa-grade hydrotherapy experience directly to any backyard, patio, or indoor space. Boasting an optimized 73 by 73-inch square layout, this model yields up to 20% more structural legroom than traditional round tubs, comfortably accommodating up to six adults without crowded seating or sagging walls. This Proseries edition features an upgraded, reinforced exterior constructed from triple-layered, pebbled synthetic leather and puncture-resistant PVC. Built around an interior vertical I-beam framework, the tub maintains its shape, rigidity, and aesthetic appeal over years of regular seasonal use.

At the center of its performance is an integrated, all-in-one heating and massage control unit built directly into the spa wall. This design saves valuable space while powering 130 high-output bubbling massage jets positioned along the perimeter to relieve muscle tension and fatigue. The rapid heating system warms water quickly up to a soothing 104 degrees Fahrenheit. It works alongside an automatic Freeze Protection system, which prevents internal plumbing and mechanical elements from freezing when ambient temperatures drop, enabling safe autumn and winter operations.

The included 15-Piece Pro Kit acts as a complete, out-of-the-box system that requires no external tools or technical assembly. A digital touchscreen control panel handles inflation and deflation in minutes while automatically maintaining desired temperatures. For safety and thermal performance, the kit features a heavy-duty, lockable insulating cover fitted with secure safety buckles to trap heat, lower energy consumption, and block outdoor debris.
