Flank the mirror with fixtures placed at eye level (around 66 inches), ideally spaced 36 to 40 inches apart. Try to see fixtures in action before you buy to make sure the amount and quality of light is sufficient. If there's no room for side sconces, install a long fixture on the wall above the mirror. Don't rely on a recessed ceiling fixture (think Dracula face).
Another thing to do is to add a few matching accessories such as towel bars and toilet paper holder and change the fixtures to unify the look of the bathroom’s hardware. Sets of bathroom fixtures may available on home improvement stores that you can purchase at fairly affordable cost. What a perfect unity style of the bathroom remodels ideas you should try!
Turn off the main water supply to the house, and in a convenient location, cut the hot and cold water supply pipes for the bathroom. Also cut out and remove all the existing water lines and fittings in the bathroom. Finally, cut out and remove the vent section leading to the sink and the main stack 5 in. below the vent tee. Stuff rags into open drain lines to keep sewer gas out of the house.
