Why does one shower in my house not get hot?

If the water in your shower isn’t getting hot, the problem could be the temperature control on the water heater. If you have an older unit, the cold water supply dip tube could have deteriorated. In that case, a worn-out dip tube could send cold water up to the hot water feed pipe, resulting in no hot water.

Why is my shower water cold?

Inspect Your Shower Valve Sometimes, the washers or O-rings have worn out which makes the valve not properly work. This can cause cold water to come through the showerhead. You may need to replace some of these parts if there is an issue with your shower valve.
