How do I fix a leak in my bathroom sink?

First, you need to locate the source of the leak. This may require turning off the water supply and disassembling the sink. Once you have identified the source of the leak, you can replace the seals or washers that are causing the issue. If the leak is coming from a pipe, you may want to consider using plumber's epoxy or pipe tape to seal the leak. Finally, make sure to reassemble the sink and turn on the water supply to check for any remaining leaks.
