If you have a double vanity in your bathroom with two sinks, you might want to think about putting two sets of lights in your bathroom; one set of lights would go on either side of the mirrors. In this scenario, the lights ought to be set at the same height on both sides, which is somewhere between 75 and 80 inches above the ground.
When installing bathroom vanity lights, it is essential to take into consideration the dimensions of your mirrors as well as their placement. It is recommended that the lights be mounted at a spacing of approximately 91 centimetres (36 inches) apart on either side of the mirror. When you are standing in front of the mirror, the lights should be set at a height that is at the same level as the top of your head.
By adhering to these rules, you will be able to ensure that the lights in your bathroom vanity are installed at the appropriate height to achieve the highest level of functionality and aesthetic appeal.
