If you've ever experienced the frustration of trying to wash your hands or face in the bathroom sink, only to find that the hot water isn't working, you're not alone. This is a common issue that many people face, and it can be incredibly inconvenient. Not to mention, it's a problem that needs to be fixed as soon as possible. There are a few different reasons why your bathroom sink may not have hot water, while your bathtub still does. Let's take a look at some of the possible causes and solutions.Hot water not working in bathroom sink
One of the most common reasons for no hot water in the bathroom sink is a malfunctioning faucet. Over time, the internal parts of a faucet can wear out or become clogged with mineral deposits, preventing hot water from flowing properly. In this case, you may need to replace the faucet or have a plumber come in to repair it. Another possible cause is a problem with the hot water supply. If you have a tankless water heater, there may be an issue with the heating element or gas supply. For traditional water heaters, there could be an issue with the pilot light or thermostat. In either case, it's best to contact a professional to diagnose and fix the problem.No hot water in bathroom sink
If you have recently had any plumbing work done, it's possible that the hot water supply to your bathroom sink was accidentally turned off or disconnected. Check the shut-off valves under the sink to make sure they are fully open. If they are, then it's likely an issue with the pipes and you may need to call a plumber. In some cases, the problem may not be with your bathroom sink at all. If you have a tankless water heater, there may be a problem with the hot water flow rate. This could be due to a clogged filter or a buildup of sediment in the pipes. Regular maintenance of your water heater can prevent these issues from occurring.Bathroom sink hot water not working
It can be frustrating to find that your bathroom sink has no hot water, while your bathtub does. This is often a sign of a problem with the faucet, as mentioned earlier. However, it could also be an issue with the hot water supply line specifically for your bathroom sink. If this is the case, a plumber will need to inspect and repair the line. Another possible cause is a blockage in the hot water line leading to your sink. This could be due to mineral deposits or debris, which can restrict the flow of hot water. Regularly cleaning your pipes can prevent this from happening.No hot water in sink but hot water in bath

This can cause a leak or a complete blockage, resulting in no hot water. In this case, you will need to have the line replaced by a licensed plumber. Another potential cause is a malfunctioning pressure balancing valve. This valve helps to regulate the temperature of the water coming out of your faucet. If it's not working properly, it could be preventing hot water from flowing. This is also something that a plumber will need to fix.Bathroom sink has no hot water

This could be caused by a buildup of hair, soap scum, or other debris. Regularly cleaning your pipes can prevent this issue from occurring.Hot water not coming out of bathroom sink
