Do you have a cold plunge pool at home? If so, is it something you made?

I would go the cooler route if I was starting today.

I’m very lucky that a gym on my walking route to work installed a cold plunge. So I can get cardio and sauna from the same routine. (The effects in the first comment can and do come from pure plunge tho.)
