So I picked hot (like just three steps or so above warm) because I do like to give a good sweat, but there are days I'll do cool showers (never cold). Just like, on the "medium" side of cold. Especially after a VERY hot day, it feels nice on the skin.
I will never do a too cold or too hot shower. My body will instinctively jump outta the shower if I do. Same way with my baths -- I need to be comfortable.
