Shower going hot and cold?
Note when the temperature changes and whether the shower pressure or other bathroom outlets also change. Those details help separate a shower-specific plumbing symptom from a wider hot-water question.
What is changing?
Hot, then cold
The water changes temperature while the shower is being used.
Pressure changes too
The flow weakens or changes at the same time as the temperature.
Other taps are normal
The symptom appears limited to the shower rather than the whole property.
Control or fitting issue
A handle, valve, hose or shower head is loose, stiff or leaking.
Shower plumbing or wider heating?
Shower-specific symptom
If other taps are normal and the change is limited to the shower, describe its controls, head, hose, pressure and temperature pattern.
Shower repair serviceWider hot-water question
If several hot-water outlets change or the property has a wider heating concern, say so clearly. This page does not make boiler or gas repair claims.
Bathroom plumbing contextPause and describe what you can see
Water is escaping into a wall, ceiling or floor.
