A jacuzzi is a type of hot tub or spa that features jets for hydrotherapy and relaxation. It is often filled with warm water and can accommodate multiple people, making it a popular choice for social gatherings or personal relaxation. The jets create bubbles and currents that can help soothe sore muscles and improve circulation. Jacuzzis are commonly found in homes, hotels, and wellness centers. They can be installed indoors or outdoors and come in various sizes and designs. Many models also include additional features like lighting, sound systems, and temperature controls for enhanced comfort and enjoyment.
