No one mentioned (probably an assumed thing) to turn the water on full hot to let it warm up, then move it to the preferred mix position. Doesn't waste the cold water which will stay more or less the same temp, it's only flushing out the cold in the hot water line. And because you have it fully on hot, it takes less time.
Or get a tankless water heater to get it almost right away. I've seen debates on which is a better choice when factoring everything in, and I think it's a close tie with no clear winner, each having their caveats.
Well, there's those suicide showerheads containing the heating element...
No thanks, I'll use a toaster the old fashioned way.
This is true, but a lot of tankless sells advertise a feature that some have that recirculate the hot water so it's available without the wait.
So some people assume it's a feature all tankless have.
In Asia these tankless heaters are in the shower room itself, when they are not turned on there's no water in the pipe (in the part after the heating element).
or install a circulator so cold water in the hot water pipes get back into the tank to get reheated
