1. Keep things light and bright

Even without windows, you can make your small bathroom look brighter by bringing in bright and breezy colors.

“If this is a bathroom that gets a lot of use, you may prefer to keep it feeling light, bright, and as large as possible,” says Amanda Wyatt, interior designer and founder of Design Insider.

“Sometimes white feels washed out and boring, so consider using a delft tile [tin-glazed white and blue tiles made in the Netherlands] or wallpaper for a pretty splash of blue,” she suggests.

We like the Apollo Tile from Wayfair which is made from a beautiful porcelain material and can be used on the walls and floor.

2. Hang up a mirror

A mirror is absolutely a bathroom essential and is a brilliant way to add dimension when decorating a small bathroom without windows.

“Mirrors are an age-old trick for making a space seem larger. For a powder room, I like a mirror with a built-in shelf for hand soap, lotion, a candle, or other decor,” Amanda says.

To increase the functionality of the mirror, you could always choose a mirrored cabinet, such as the Kohler Frameless Medicine Cabinet from Wayfair which has adjustable shelves and a reversible door.

3. Add artificial lighting

Since natural light isn't an option when decorating a small bathroom without windows, it’s a good idea to bring in savvy small bathroom lighting ideas.

“I always try to bring in a pair of sconces on each side of the bathroom mirror to bring in as much light as possible, which is so important in a bathroom,” says Shani Core, interior designer and founder of Shani Core Interiors.

Make sure they’re as chic as possible to maximize style potential in this tiny space. 

For example, the Urban Ambience Luxury Wall Sconce from Walmart is similar to the one Shani styled, made from opal glass, and is available in satin gold, brushed nickel, and midnight black.

4. Bring in glossy surfaces

When decorating a small bathroom without windows, incorporate surfaces like polished tiles to subtly bounce light around the room. 

“Choose glossy ceramic tiles (the MSI Marza Tiles from Wayfair are scratch-resistant, stain-resistant, and easy to maintain) for the shower or backsplash to add a touch of sparkle,” explains Nina Lichtenstein, principal designer and founder of Nina’s Home Design.

Reflective surfaces will not only enhance the brightness of any lighting, but will make the bathroom feel more luminous.

5. Create contrast

Incorporating contrast and interest with accent colors and textures throughout your small bathroom will distract from the fact it doesn’t have windows.

“Add pops of color and pattern through towels, rugs, or decorative accessories,” suggests Nina. 

She also suggests incorporating metallic accents like brass or chrome fixtures (the Southern Hills Polished Chrome Cabinet Pulls from Amazon have a polished finish and come with mounting screws) to add visual interest and reflect light.

6. Keep clutter to a minimum

Maintain a clean and open feel in your small bathroom by making sure all your toiletries are stashed away and that you’ve utilized small bathroom storage solutions.

“Choose streamlined fixtures and furnishings with sleek designs and wall-mounted storage solutions to free up floor space and create a sense of openness,” Nina says.

Less clutter means more room for light to come through and illuminate the space. You can go for one in a metallic color to further enhance this too, like the Aurora Trade Hexagonal Wall Shelf from Walmart which has strong reinforcement and won't require any drilling.

7. Decorate with indoor plants

Bring life into your windowless bathroom by adding in gorgeous indoor plants and luscious greenery. 

Nina says, “Choose low-light plants like peace lilies (the Costa Farms Peace Lily from Walmart loves high levels of humidity), snake plants, or ferns that thrive in bathroom conditions.”

You can place plants on shelves, countertops, or in hanging baskets to add a refreshing touch of nature to your space.

These pro tips will help you to maximize light, create a sense of openness, and make the most of your compact space. 

“With the right approach, your windowless bathroom can become a bright and inviting room that you'll enjoy spending time in,” Nina finishes by saying.
