Putting electricity in the cabinet box can be a nice touch as well — if you want to keep hair dryers, toothbrushes and other necessities ready to go. Having a custom vanity design can help you consider all of the small details that often get overlooked, like features that work whether you're left-handed or right-handed. Of course, choosing your vanity materials, style and design has a lot to do with how you feel about your home, too. A custom-designed vanity in the master bathroom of your "forever home" might make sense, but a store-bought vanity could work just fine in the guest bathroom of a home you plan to sell down the road.Share your story: Did you just update your vanity?
