Jacuzzi          

Whirlpools differ from spas, or hot tubs, in that they are filled and drained with each use. But like spas or hot tubs, the velocity of the water can be quite high, making it unsuitable for those suffering from certain medical conditions, and children. Air (bubble) massage tubs might be a better choice in these cases.

Water is drawn from the bath suction by a pump which circulates it around the bath to the jets. Each jet contains a venturi, a vented constriction near its opening that injects air into the water. In most cases, the ratio of air to water can be adjusted at a central control, at each jet or at both sites.

The choice of whirlpools continues to grow. Features abound. You will be faced with a wide range of sizes, styles, colors, and designs.

Pay close attention to their size, shape, and safety features, and the ease with which you can get in and get out. While some look great, you almost have to be an acrobat to climb into them.

If this is impractical because the display model is filled with water, try out a comparable model. Don't be embarrassed. People do it all the time. Make sure it's the right size for you and offers the kinds of features you prefer.
