For homeowners upgrading bathrooms or professional spa managers seeking bath accessories for therapeutic treatments, this system provides reliable hydrotherapy for home or commercial use. Transforms standard bathtubs into therapeutic retreats or elevates commercial spaces with adjustable water flows targeting back, neck, and muscle tension zones. Water circulation with jet designs maintains consistent hydrotherapy performance while resisting mineral buildup in chlorinated or spa water environments. Engineered nozzles with ABS fittings deliver precise water pressures and ensure seamless compatibility across residential and commercial hydrotherapy systems. Use scenarios - Home: install in a standard tub to deliver customizable back and neck massages during daily baths. - Spa or hotel: offer guests consistent, targeted hydrotherapy sessions in treatment rooms. - Multi-unit facilities: equip multiple tubs in hotels or fitness centers with a single, compatible hydrotherapy system.
