An asymmetrical mirror does what a rectangle cannot. It softens the hard lines of tile, counters and cabinets, and it gives the bathroom one piece that feels chosen. This guide covers how to size one for a single or double vanity, how high to hang it, and which frame finish to pick.
Why an asymmetrical mirror works in a bathroom
Bathrooms are full of straight edges. An organic shape breaks that grid and draws the eye to the vanity wall. Because the outline is irregular, it also hides small alignment gaps with faucets and sconces that a rectangle would expose. You can compare shapes side by side in our asymmetrical mirrors collection.
Sizing for a single vanity
Measure the width of the vanity top first. A good starting point is a mirror 2 to 4 inches narrower than the vanity, so the edges do not hang past the cabinet. As a rough guide by the longest side of the mirror:
- 24 to 30 inch vanity: a mirror with a longest side of 20 to 25 inches.
- 36 to 48 inch vanity: a longest side of 38 to 43 inches.
- 60 to 72 inch vanity: one mirror with a longest side of 55 to 70 inches, or two smaller mirrors.
The Biga asymmetrical mirror comes in eleven sizes, from 20 x 10 inches to 80 x 40 inches, so there is usually a standard size close to what you need.
Double vanity: one large mirror or two?
One wide mirror reads as a single calm statement and makes the room feel larger. Two mirrors give each sink its own zone and leave space for a sconce between them. If the wall has a window or a cabinet in the middle, two mirrors usually fit better. If the wall is clear, one large asymmetrical mirror is the stronger look.
How high to hang it
Aim for the center of the mirror at eye level, roughly 57 to 65 inches from the floor. Leave 5 to 10 inches between the bottom of the mirror and the faucet or backsplash so water spots stay off the glass.
Choosing a frame finish
Our mirrors come in six frame finishes: Black, Gold, Bronze, Chrome, White and Antique Gold. Matching the faucet finish gives a quiet, coordinated look. Contrasting it, such as a black frame with brass fixtures, makes the mirror the focal point.
Adding LED backlighting
Every size can be ordered with a Daylight LED. The light sits behind the mirror and washes the wall around its edges, which gives a soft glow in the evening. It works with a dimmer. Treat it as ambient light and keep your main vanity lighting for tasks like shaving or makeup.
When a standard size does not fit
Alcoves, sloped ceilings and extra wide vanities rarely match a catalog size. In that case, use Your Custom Design to send us your measurements and we will make the mirror to fit.
