A vanity mirror does more work than almost any other fixture in the bathroom – it bounces light around the room, it’s the thing you look at every morning, and it’s often the single largest reflective surface in the house. Despite that, it’s usually the last thing homeowners think to customize.
At Big River Glass, custom mirrors are one of our most requested residential services. Here’s how to think through sizing, lighting, and style before your next bathroom project.
Sizing Your Vanity Mirror
As a general rule, a vanity mirror should be sized a few inches narrower than the vanity or countertop it sits above on each side, and hung so its center lands roughly at eye level for the average adult in your household. For double-vanity bathrooms, homeowners are increasingly choosing one continuous mirror spanning both sinks rather than two separate mirrors – it reads as more custom and eliminates an awkward center seam.
Framed, Frameless, or Beveled
Frameless mirrors with polished edges give a clean, modern look and work in almost any bathroom style.
Beveled-edge mirrors add a subtle traditional detail along the perimeter without the cost of a full frame.
Custom wood-framed mirrors, available through partners like Precision Frameworks and Larson Juhl, let you match your mirror to existing cabinetry, trim, or a specific design style – from a simple modern frame to an ornate traditional moulding.
Lighting Integration
Backlit and edge-lit LED mirrors have become one of the most popular upgrades we install. An integrated LED perimeter provides even, shadow-free lighting for grooming and applying makeup – a noticeable improvement over a single overhead fixture. Many models also include a built-in anti-fog pad on the back of the glass, which keeps the mirror clear during and after a hot shower.
Custom Shapes
Rectangular mirrors remain the standard, but arched, oval, and geometric shapes are increasingly popular for powder rooms and primary bathrooms alike. Since we custom-cut every mirror to spec, unusual shapes and sizes are just as achievable as a standard rectangle.
Built for Louisiana Humidity
Bathroom mirrors take a beating from steam and moisture. We use moisture-resistant backing and edge-sealing on every custom mirror to prevent the black edge spotting that shows up on lower-quality, unsealed mirrors over time – a common problem in humid climates like Baton Rouge.
