Take your time to explore the Cetra®. Like its namesake, the Cetra® rectangle bathtub is an undeniable classic. This uncomplicated bathtub features supportive, built-in armrests for optimal comfort. The Cetra® is perfect for any and every bathroom setting from traditional to contemporary. Uncomplicated, straightforward, and utterly heavenly. Strong and durable, acrylic Jacuzzi bathtubs are reinforced with a proprietary formula that ensures a long-lasting quality surface. The non-porous characteristic of acrylic defends against the penetration of microorganisms into the surface. Jacuzzi bathtubs are ergonomically designed to maximize the benefits of hydrotherapy, allowing people of all body types to immerse in warm water fully. Benefits of a full-body soak: Relieves the weight of gravity on joints. Provides 360-degree support for sore and tired limbs. Decreases swelling and inflammation. 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.
