Why is Bath tub water cold, but Shower and sink are Hot? Fix!!!
Thermostatic Mixer Valve

When you aren't getting hot water in the bathtub and the other faucets are operating normally, you don't have to look far for the problem. It's either in the faucet or in the pipes supplying the faucet, and the latter is not common. It could be a build-up of minerals blocking the valve, but if your faucet has a single handle, it may have a scald prevention control, and the control could be misadjusted.
Adjusting the Temperature Limiter

Before you suspect mineral deposits, inspect the temperature limit adjustment on your single-handled tub faucet. To do that, remove the handle with a screwdriver or hex wrench. On most faucet models, the limiter is a plastic disk that fits on the faucet stem and prevents you from turning the faucet too far to the hot side. You can usually simply pull this disk off and rotate it a few notches to increase the temperature. You may have to rotate it clockwise or counterclockwise, depending on the faucet model.
