A $15 Mirror Trick Turns a Rental Bathroom Door Into a Designer Look

Nick Lowry found a way to bring a piece of high-end design into a rental bathroom without touching the door’s structure. His renter-friendly bathroom door DIY uses circular mirrors to suggest the porthole doors of French designer Jean Prouvé, and he says the whole project comes in under $15.

The appeal of the original is easy to understand. Lowry has said he loves Prouvé’s porthole doors because they let light through. But as a renter, he could not justify the cost of the real thing, so he built a version that could be undone later.

From inspiration to Amazon cart

Lowry’s solution was a set of 12-inch acrylic mirrors, not glass. He found them on Amazon, where he said a pack of 12 cost $25. A set of eight mirrors is priced at $15, which keeps the project within his stated budget.

Acrylic matters here for more than price. The mirrors are lightweight, and the set arrives with adhesive strips. Lowry, however, recommends 3M tape instead of the included strips, because it should be easier to remove when the time comes to take the mirrors down.

Planning the layout before sticking anything

Before mounting a single mirror, Lowry used a digital editor to test how the arrangement would look. He settled on a tight vertical column of three mirrors in the center of the door, a configuration he said looks best.

His measurements offer a starting point rather than a rule: 22 1/8 inches from the top and bottom, 11 inches in from each side, with a 4.5-inch gap between the mirrors. Door sizes and shapes vary, so those figures will need adjusting for a different door.

He mounted mirrors on both sides of the door, not just one. That doubles the light-bouncing effect, sending reflections through the room rather than stopping at a single surface.

What the mirrors do for a small bathroom

Mirrors are a familiar tool for brightening small, dark rooms. They reflect light back into a space and can act like faux windows, which makes a room feel larger than its footprint. In Lowry’s bathroom, the new door brought light into a corner that had previously been shadowed.

The finished result gives the door a modern look and opens up the space visually. Lowry said it now matches the jewelbox feel of the rental bathroom, a description that fits the layered, reflective quality of the mirror arrangement.

For renters who want a designer-inspired upgrade without permanent changes, the project requires no structural work. The mirrors go up with tape, the layout can be planned in advance, and the cost stays low. The unknowns are the usual ones for any adhesive project: long-term durability, whether the tape leaves marks, and whether the mirrors remain available at the stated price.
