It depends on the make and model of the hot tub, but most last around 8 to 10 years.

It depends on how well you take care of it and the quality of the tub. With proper maintenance, a hot tub should last anywhere from 8 to 10 years. However, if you don't take care of it properly or if you get a low-quality tub, it may only last for 4 or 5 years. So it's important to do your research before you buy one and make sure you find a quality model that will last.
