How to Hang a Bathroom Mirror in Front of a Window

Our master bathroom presented an unusual mirror challenge. Instead of the usual mirror-over-the-sink arrangement, there was a window (pictured here on moving day before we removed the bi-fold doors).

Although the photo makes the window look bright and welcoming, it actually looks directly at the neighboring house. That side-window placement isn’t ideal for brushing your teeth, shaving, styling hair, or stepping out of the shower without worrying about what neighbors might see. We needed a privacy fix—and a functional mirror—right away.

Ironically, the room wasn’t lacking in mirrors. There was a full-length mirror on the water-closet door and another mirror on the nearby medicine cabinet, which made for two mirrors within a four-foot span of wall.

After removing the old backsplash, the vanity area was refreshed, but we still wanted a mirror directly in front of the sink. Living for a few weeks with the mirrors clustered to the right made us crave the traditional placement of a mirror above the sink. We decided on a less conventional approach: hanging a mirror on the window frame itself.

We mounted the mirror to the window frame. While it does block a bit of natural light, the bedroom and bathroom have several other large windows, so light wasn’t an issue. More importantly, the mirror provides privacy from the neighboring house and restores the practical function we were missing. Shaving, grooming, and everyday tasks are much easier when you don’t have to twist at odd angles to see your face.

The mirror is from the Allen + Roth line at Lowe’s. After searching several stores for the right round mirror without success, we were happy to pay $65 for a distinct, clean design that fit the space—much less than similar, high-end alternatives. Hanging it took just one screw through the wood between the window panes and a small square of Velcro at the bottom to stabilize it, preventing any wobble. The window can still open and close because the knobs sit at the bottom of the panes rather than the center, so the mirror doesn’t block them.

We had considered a large round mirror to balance the angular lines of the windows, but a perfectly centered round mirror would have needed to be very wide for both of us to see our whole faces given our ten-inch height difference. The mirror we found has a unique overlapping-oval shape, which provides a bit more reflective area at the bottom—exactly the extra “mirror real estate” we needed. That extra coverage means both of us can actually see our faces and necks comfortably, which made my partner genuinely delighted.

We also thought about a folding mirror mounted on the side wall, but that looked too much like a typical bathroom installation. Hanging the mirror on the window feels more decorative and reads like a vanity tucked into the corner of a bedroom instead of a sink facing the bed. It also created better visual balance in the room.

To finish the look, we removed the old mirrored medicine cabinet and the towel bar on the opposite wall. The towel bar was replaced by a neatly folded white towel next to the sink, and both the medicine cabinet and towel bar were donated to a local ReStore.

With those elements gone, the space reads less like a bathroom and more like a bedroom vanity nook. We planned to paint the bedroom soon and were considering painting the mirror frame a soft color to better blend with the window trim—white or gray were potential choices, but the final decision hadn’t been made yet.

From the outside, the mirror appears as a simple tan shape centered in the window, blending reasonably well with the surrounding trees and exterior features. Frosting the glass could improve privacy further, but with much of the window now obscured by the mirror and the neighbor’s house set back a bit, we felt comfortable that shapes wouldn’t be distinguishable anymore.

We’re thrilled to have a mirror above the sink again. It’s practical, stylish, and offers the privacy we needed while keeping the room feeling like part of the bedroom. The solution isn’t conventional, but it works beautifully for our layout and needs.
