I always turn on my water with my head outside the tub to avoid this problem. It works every time
As far as I know, not once! I also know some people who turn on the faucet to fill the tub first and then swap to shower head to also avoid the problem!
just me then
Huh. Turn it on BEFORE you fucking get in.
That's why I hold the showerhead over the sink until I reach the required temperature of the water
