For any type of workshop, I like outlets at least 48" high. Outlets much lower just tend to get in the way for me.
The outlets in the family room are all 48" off the floor. Looks a bit odd but, it used to be the stand alone garage/shop before we added on and incorperated it into living space. The walls were lined with benches so the outlets were accessible at 48"
I could have lowered them when we remodeled but wow.
I really ought to do it right and raise the ones that are in the way. I should sleep on it and make a good decision in the morning.
