Strong and durable, acrylic Jacuzzi® bathtubs are reinforced with a proprietary fiberglass/resin formula that ensures a long-lasting quality surface. The non-porous characteristic of acrylic defends against the penetration of microorganisms into the surface. Hydrotherapy (the therapeutic use of water): Jacuzzi® bathtubs are ergonomically designed to maximize the benefits of hydrotherapy, allowing people of all body types to fully immerse themselves in warm water. Benefits of a Full-Body Soak: 1. Relieves the weight of gravity on joints 2. Provides 360-degree support for sore and tired limbs 3. Reduces swelling and inflammation 4. Increases circulation and oxygen in blood cells. Hydromassage (moving water for optimal massage) - Jacuzzi jet systems push high volumes of water uniquely mixed with air into a hydromassage bath. Gentle pressure on muscle tissue increases circulation. This stimulates blood flow, which can help muscles and joints recover from fatigue or injury, and makes moving easier. The exclusive, patented TargetPro jetting offers adjustable jet stream direction and intensity for a personalized massage experience.
