When you are looking to light a bathroom that has a double bowl sink the big question is where to place the lighting. The three options are either using a separate 2 or 3 light fixture over each sink, opting for a longer 4 or 5 light centered between the two, or using three 1 bulb sconces.
I tend to recommend using a separate 2 or 3 light fixture over each bowl to my customers. It gives the bathroom a more finished look, defining the two sinks. Almost any 2 bulb fixture will do, however if you want to use a 3 bulb fixture make sure the length of the light isn’t too long, or combined they will look like one 6 bulb fixture across your vanity. In addition, by centering a fixture over each sink, you are ensuring proper lighting over each bowl. Remember to always max out the wattage of the fixtures ( 1oo watt max in most cases), and put the light fixtures on a dimmer.
If you prefer a 4-6 bulb fixture centered between the two sinks then go for it. Sometimes this makes the most sense when you have a plate glass mirror across the whole vanity. Remember too that if you do not inform the contractor or electrician doing the work that you want two separate light fixtures, they may pull the wires through the wall for between the two sinks be default. My only concern with 1 light fixture centered is the light issue. To the extreme left and right of the sinks there may b a light drop off depending on the length of the vanity. Make sure that you max out the wattage and put the bathroom lighting on a dimmer.
The third option which is not that common but certainly an option is to use three 1 bulb fixtures. My only concern here is that you might not get adequate lighting, however with a ceiling fan/light combo and maxing out the wattage this is a possibility as well.
Remember, you can never have too much light in a bathroom!
