When it comes to determining what type of mirrors to hang above a double sink bathroom vanity, you'll want to choose an option that finishes the look and style of your bathroom. So if you have a traditional double sink bathroom vanity, we suggest you opt for two mirrors in keeping with the symmetry and cohesiveness of the vanity.
Traditional bathroom vanities pair well with various mirror styles like ornate mirrors. Feel free to choose an over-the-top glamorous style with sparkling frames for a touch of pizzaz. You're also not limited to a specific shape or size, and you can feel free to let your creativity and personality shine through.
Lastly, while double vanity calls for two mirrors if you're conflicted between shape and size, why not opt for a single large mirror that's approximately the same length as your entire double vanity for a solid yet impactful wall above your vanity.
