This hot tub is an amazing starter tub. 60 degrees F seems to be the temp where you can stay in it as long as you’d like, under that it is a slow decline, but honestly your body gets used to the decline and it still feels hot unless you go down to 98. I found that you can typically stay in an hour before that happens, and when it is freezing or below keeping the cover half way on can really help maintain the heat to allow you to stay in longer! I would 110 recommend this to anyone, they are super light and easy to move, just make sure you maintain the proper chemical levels
