It depends on how well it is taken care of. A jetted tub typically lasts 10 to 15 years. However, if the jets stop working or the water starts to smell bad, it's time for a replacement. Also, keep in mind that a jetted tub uses more water and electricity than a regular bathtub, so you may want to consider replacing it if you're trying to save money on your monthly utility bill.

The average lifespan of a jetted tub is around 10 years. However, this can vary depending on the quality of the jetted tub, how often it's used, and how well it's maintained.
