The first thing you need to think about is the style of bathroom you have, along with your vanity mirror and console size, and how that changes your lighting needs. Always take into account your mirror and console while considering measurements and fixture size, as this will affect installation.

BATH & VANITY SIZING GUIDELINES

Single Bowl Vanities

Positioning the fixtures on both sides of the mirror is the best way to provide shadow-free lighting on your face. The ideal width is at least 28 inches apart, and centered at 70-80 inches above the floor. If you choose to place your lights above the mirror, the width of your fixture should be at least 1/3 the width of the vanity mirror, but should never exceed its total width.

Task Lighting

Center recessed downlights 24″ to 36″ between where the face and the mirror are at the vanity to eliminate shadows.

Vanities With Two Sinks

In bathrooms with two sinks, another great option is to mount two separate fixtures, one above each sink.
