The temperature adjustment on a single handle Delta faucet is in the valve operation itself, however, the high temperature limit is adjustable, and is probably what you are referring to. To adjust it, you have to remove the handle from the trim. Beneath the handle are two geared rings which control the high temperature limit. Remove the inner ring (they may both fall out) and turn it CCW (if memory serves..) to raise the high limit. If I got it backwards, turn the ring CW and try again.
1- plugged shower head 2- defective diverter
cold water tub facuet is corroded bye hard water builtup and needs to be replaced. Hot water is okay. Its the right one with the cold water coming out
It doesn't but you better run sir/madam their may be a ghost in your bathroom.
The shut off valve under the sink, the faucet itself, or most likely, the screen in the end of the spout is plugged. If neither hot or cold is coming out, it is kind of unlikely both shut off valves and both sides of the faucet would go bad at the same time. The screen being clogged would stop any water from coming out. The screen just unscrews out of the spout.
A trim kit is just the outside parts that you see. This will make you faucet look better, but it wont affect the function of your old valve. If your shower valve doesn't work right, replace it.
With combos of hot/cold combined. To adjust overall hot, you can do so at water htr.
Defective divertor
Take off handle and you will see how to do it. Be carefull not to let the parts fall off the stem. If they do you could go to Lowe's and ask how to put it back together. Just take the parts with you. This is for a pressure balance Delta.

Rom tub faucets can be found at your local Home Depot. Another well known home improvement store that sell them is Rona. Some lesser known companies that sell Roman faucets are Delta Faucet and Faucet Warehouse.
A tub faucet acts as a shower and can be used to bath in the bath tub. It is a pressure valve which makes the flow of water through it constant and gives a nice shower.
Faucet side.
Most of them are in the wall. The other would be a deck mount, which is mounted to the fiberglass tub deck and uses a Roman Tub Faucet.
It depends on the make of the faucets.
A Roman tub faucet does have good water pressure because it is made to do that. How good this is depends on how other brands perform in this area.
