By opening the walls
New pressure balance faucet or you can install a pressure balance valve in the water lines behind tub or if you have a crawl space you can install it on the water lines there. But install only too the lines to tub faucet. And they are not easy no matter where you install. I would just tell everyone not to use any water till you are done with shower.
You have a leak between the diverter and showerhead or the arm for the showerhead is not sealed properly into the fitting in the wall

Its a loss in water pressure to the shower.
Proably the faucet has a worn out washer, replacing the washer should fix the problem.
The shower gurgles because the water is going down the pipes.
If the faucet contains the re-direction valve (closes off the water from the faucet and redirects the water to the shower head) you need to rotate the faucet counter clock wise to unscrew it from the plumbing and replace it with a new one. Take the old one to your local box store and they can match it up for you.
It's the part of a tub control that makes the water go to either the faucet or the shower.
First make sure that the hot and cold supply lines (the plumbing) aren't backwards (hot should be on the left as you are facing the faucet) or that someone accidentally ran two hot lines. For the problem to be in the faucet itself you would have to have a single handle faucet. If this is the case the control valve is broken and should be replaced. Three handle Left= Hot Water Flow. Right= Cold Water Flow Center= Controls whether the water comes out the shower head or tub faucet. Two handle Left= Hot Water Flow Right= Cold Water Flow (Diverter Valve is elsewhere if it's a tub/shower) Single handle One handle controls both water pressure and temperature
1- plugged shower head 2- defective diverter
