I have a similar shower handle to this
The ir should be a diverter valve control , often on the spout for the tub , that closes a vlave and diverts the water to the shower. Check that that valve is completely open.
The diverter appears to be working fine. It is the kind at the end of the spout.
I agree.
I'm assuming that when the OP wrote, "The slower I fill the bath, the more water comes out the head," he was describing turning a diverter valve lever below the main valve, it looks like there's one partially hidden by the handle in his photo.
If it's been happening since he had the shower redone then he should get on the back of whoever he paid to do that work and get him to make it right. It may just turn out to be something not quite right with the diverter valve.
Or, he may have unusually high water pressure in his home, and no pressure regulator, in which case installing one could solve his problem.
I've seen situations where the pipe going up to the shower head from the valve had to be extended several feet above the the head and looped back down to prevent that kind of problem.
Lots of things to check, but the guy who did the work should fix it.

One more thought, if he can't get the installer to fix it he could always buy one of those little chrome flow adjusting valves and install it just behind the shower head. One like this:

Thats the ticket! The bath only gets used 10% of the time so it wouldn't be too bad. Thanks.
