Why is my shower too hot?
Your shower is scalding hot because the cartridge has broken down or become clogged. This can cause the water temperature to become erratic. To fix the issue, turn off the water supply, unscrew the handle, and remove the cartridge. Replace this with a brand-new cartridge and ensure everything is tightened properly.
How do you fix the water temperature in your shower when it’s always either too hot or too cold?
First, try adjusting the hot water limiter on the valve in the shower. Behind the handle there should be a screw that you can adjust to limit how much hot water the valve can let through. This is mainly to prevent scalding, but adjusting it lower could help the cold/hot ratio of the mix.

This constant in-balance between the two will cause damage to the cartridge which is housed within the valve.
