Hollywood bath has 1 center light and 2 sinks that are 50" apart (center to center). I can find an updated light fixture that is 54" long and should be adequate lighting. I would use this to avoid expense of creating 2 separate over-sink light fixtures. Large mirror is gone; countertop is granite with 2 undermount sinks. QUESTION -- Can I get away with separate sink mirrors using the 1 light? We want to sell in 3-5 years and it is a seldom-used guest bath. Thanks for your help!
