Not a Mirror: Joanna Gaines' Smart Way to Make a Small Kitchen Feel Larger

Mirrors are often used to make compact spaces seem more open, but they are not always the best fit in a tight kitchen. They can reflect clutter and take up wall space that may already be occupied by windows and cabinets. Joanna Gaines suggests a more effective solution for enlarging the look of the room: under-cabinet lighting. In an HGTV clip, the designer explains that this type of lighting "gives your space the illusion that it's bigger than it really is."

The effect comes from reducing shadows and reflecting light across other surfaces, which makes the kitchen feel brighter and more layered. It also improves how the room functions, since the light falls directly on the work area. By directing attention to the counters, it can even make them appear broader.

Gaines recommends having an electrician install under-cabinet lighting for a cleaner, more lasting finish. Still, plug-in options are a simple alternative for renters or for anyone who wants to avoid electrical work. Light bars usually cost between $12 and $60, while battery-powered versions typically range from $8 to $20, depending on size and style. Both are widely available at home improvement stores such as Home Depot or Lowe's.

How to choose the best under-cabinet lighting for a kitchen

In many of Gaines' kitchen makeovers, bar lights appear beneath the cabinets. These slim strips spread light evenly across a larger area and are easy to hide. LED strips and puck lights are other popular choices. LED strips can run continuously along cabinets, including around corners, while puck lights can be placed wherever more focused illumination is needed.

Color temperature matters as well. Gaines adjusts her choices based on the room and the mood she wants to create. Cooler light can make a space feel sharper and more open, while warmer light gives a softer, cozier look that suits larger kitchens.

Placement also affects the result. Lights installed toward the front of the cabinets make work surfaces easier to see, while fixtures set farther back can draw attention to decorative tile or attractive canisters. To get the full benefit of under-cabinet lighting, Gaines advises, "Anything from the countertop up, keep light." Light, neutral finishes reflect the most brightness, helping even a kitchen without windows feel airy.
