Typically, it is best if the mirror is centered over the sink. If you have two sinks and are putting up two mirrors, they should each be centered over their respective sink. You'll also want to make sure that you leave enough room on either side of the mirror so it's hanging evenly.
Hang the mirror 5” to 10” inches above the sink. Hang the mirror a few inches above the highest part of the faucet. Center the mirror in between the vanity lighting and the sink.
It's Okay to Put Your Bathroom Vanity in Front of a Window—If It Looks Like This. This spa-like space's counter is basically never-ending.
Yes, Vanities Should Be Attached to the Wall
The reason for this is to hide and protect your plumbing. Most of the time, plumbing comes through the wall underneath the sink, and the vanity's cabinet keeps it hidden.
Ideally, you'll want to put your makeup vanity in front of a window: this ensures you get a supply of natural light that distributes evenly across your face. Try to place the vanity centrally in front of the window: if it's off to the edge, you'll get some misleading shadows on your face's far side.
Vanity lights should be hung over the mirror and centered on the plumbing. The centerline of the vanity light should be hung 72” above the floor. For taller ceilings, or taller people, that height can increase to 80” but should never exceed that distance.
It is recommended to aim for 52-54 inches mirrors. Why? Mainly, it is for the sake of aesthetic. If the mirror is wider than the vanity, the mirror will overpower the room and make other things in the bath appear smaller.
If you're working with an average-size medicine cabinet or mirror, place two lights on either side of the mirror at eye level, about 65 inches from the floor and a couple inches from the edge of your mirror. For a single light above the mirror, place it around 80 inches from the floor for an ideal height.
Unless you're installing a full wall mirror that spans from the top of the vanity to the ceiling, it's best to place the mirror above the vanity's highest point — usually about five to 10 inches above the top of the faucet.
'The preferred mirror shape in a bathroom depends on the design aesthetic and other room elements. Classic square or rectangular mirror shapes complement modern and contemporary spaces with sleek profiles. Round or oval mirrors add organic curves to transitional and rustic spaces. '
Hang the mirror so that it is eye-level for most users. Hang the mirror so that the mirror reaches a foot above and below the eye line of the people who will be using it, or so that it is a few inches higher than eye level for the tallest person in the home.
Place bathroom sinks 20 inches from the back wall, recommended. The bare minimum is 15 inches. This is measured from the sink's center point to the wall. Bathroom vanities with precut sinks should already meet the spacing guidelines.
A little extra space goes a long way in the bathroom, especially when two people must use it at the same time. NKBA designers recommend a 30″ clearance between the front edge of a fixture, such as a vanity or toilet, and any other fixture or wall. The building code allows for a minimum of 21″.
Many homeowners like to place their vanities along the walls or corners. This is ideal because it doesn't leave any extra gaps that might create wasted space in the room. Having a vanity on the corner of the bathroom allows you to put both a main mirror as well as a side mirror on both walls of the corner.
Go big with your mirrors
Instead of just hanging a small bathroom mirror above the sink, consider mirroring a whole wall, or at least a large portion of it. This acts like a window in bringing a lot more light into the room and creating the illusion of a much bigger room.
The most common vanity mirrors will have widths of 20-25 inches. Anything under 20 inches is fairly uncommon and typically used as shower or wall mirrors. While 20-25 inch mirrors are the most common, 25-35 inch vanity mirrors are a great choice as well.
The most common way to determine your mirror size is choose a mirror that is 1-2 inches shorter than the width of the countertop of your bathroom vanity.
Lighting the Vanity Right
To eliminate shadows under the chin, eyes, and cheeks, fixtures should be mounted on either side of the vanity mirror (or on the mirror's surface, if it's large), 36 to 40 inches apart. The center of each fixture should be roughly at eye level, or about 66 inches above the floor.
For double vanities with two mirrors, use three lights total with one in between. You can even use hanging pendant lights in place of the sconces if wall mounting presents a problem. Place your sconces or pendant lights between 65 and 70 inches above the floor, or at about eye level.
When buying a bar-style or multiple-light fixture, a good rule of thumb is to pick one that's no wider than the vanity cabinet (it is OK, however, if the fixture is wider than the mirror). Long vanities might require multiple fixtures, and double sinks look best with a separate fixture over each.
Feng Shui says to create balance in the bedroom, the second biggest piece of furniture should be placed opposite the bed. So, place your chest of drawers, desk, vanity, chaise, sofa, etc. against the wall across from your bed.
Unless you're looking for a monochromatic style, pick a vanity that's a few hues darker or lighter than your walls. Doing so will prevent the room from looking drab or boring.
