What is the difference between a hot tub and a jacuzzi?
A hot tub, usually found outside, continuously holds water at a temperature of around 100 degrees and is treated with bromide (similar to chlorine) for sanitation. The same water is used throughout your stay. A jacuzzi is more like a jetted bathtub. The water is added and emptied for each use. Both have jets and/or air pumps to provide for your relaxation.
