Brrrrr. I have a very large tub out side that takes a water heater's worth of water for a soak. I turn off the water and get in when its about 113F or 45C.....perfect! it cools down ans I soak, but I love it rather hot to start with.
More times than I have fingers and toes to count on my friend..lol. And as for my lack of hot tub experience one person thought it was un Canadian to not own one...lol! I always had a more pressing use for that kinda cash plus the whole going out in the snow and cold to climb into a hot tub has zero appeal.
