If you're experiencing hot water in your kitchen sink but not in your shower, the first thing you should check is your water heater. This is the most likely culprit for the temperature discrepancy. Make sure that your water heater is turned on and functioning properly. If it's an older model, it may be time to replace it with a new, more efficient one. You should also check the temperature setting on the water heater to ensure that it's set high enough to provide hot water to your shower.Check the water heater
The next step is to check the shower faucet itself. Sometimes, the hot water valve on the faucet can become stuck or clogged, preventing hot water from flowing through. Try turning the hot water valve on and off a few times to see if this helps. If not, you may need to replace the shower faucet altogether.Check the shower faucet

Lastly, if you have a removable showerhead, make sure to check it for any clogs or blockages. You may need to remove it and soak it in a solution of vinegar and water to dissolve any mineral deposits. If your showerhead is not removable, you can still try to clean it by pouring the solution into a plastic bag and tying it around the showerhead, letting it soak for a few hours before rinsing it off. In conclusion, experiencing hot water in your kitchen sink but not in your shower can be frustrating and inconvenient. However, by following these steps and checking for common issues, you should be able to resolve the problem and enjoy hot water in all areas of your home once again.Check for a clogged showerhead
