18 Space Themed Bedroom Ideas to Inspire Cosmic Dreams

Ever dreamt of sleeping among the stars or walking into a room that feels like a spaceship? A space themed bedroom can make that fantasy a reality. From glowing planets to galaxy-inspired walls, these bedrooms aren’t just about decoration—they’re about creating a playful, imaginative escape.

These space themed bedroom ideas will help you bring the cosmos indoors. Whether you’re designing for a child, a teen, or a stargazing adult, these ideas mix color, light, and textures to create a room that feels out of this world. 

1. Galaxy Wall Murals

Transform your bedroom walls into a galaxy with deep blues, purples, and sparkling stars. Murals or decals with nebulae, planets, or constellations create an immersive cosmic experience.

This works because a feature wall immediately sets the theme and gives the room depth, making it feel like you’ve stepped into space. It’s bold but fun, perfect for a statement bedroom.

Tip: Pair with neutral bedding and glow-in-the-dark stars on the ceiling for a magical effect at night. 

2. Glow-in-the-Dark Stars and Planets

Add glow-in-the-dark star stickers or hanging planets to the ceiling to mimic a night sky. They turn off lights and instantly create a dreamy, celestial ambiance.

This idea works because it adds whimsy and encourages imagination while being easy to install. It’s especially perfect for children who love astronomy.

Tip: Place planets at varying heights and distances for a realistic 3D effect. 

3. Planet-Themed Bedding

Choose bedding featuring planets, moons, or galaxies in bold colors like navy, black, or purple, paired with metallic accents.

This works because it ties the theme together without needing full wall transformations. The bed becomes the centerpiece, drawing attention and enhancing the cosmic vibe.

Tip: Mix printed sheets with solid-colored throws to prevent the room from feeling too busy. 

4. Space Shuttle or Rocket Decor

Incorporate models of rockets, spaceships, or sci-fi-inspired lamps on shelves or bedside tables. These items add personality and fun.

This works because small, themed elements reinforce the space concept without overwhelming the room. It keeps the decor playful and imaginative.

Tip: Use LED rocket lamps to double as ambient night lighting. 

5. Star Projector Lights

Install a star projector that casts stars, galaxies, or nebulae across the walls and ceiling. Some even allow color changes and motion effects.

This idea works because it creates a dynamic, immersive environment that transforms the room instantly at night. It’s perfect for bedtime or a relaxing stargazing vibe indoors.

Tip: Choose a projector with adjustable brightness to avoid overpowering the room. 

6. Metallic Accents

Use silver, gold, or chrome finishes in light fixtures, drawer handles, or wall decor. Metallic touches reflect light and mimic the shimmer of distant stars.

This works because metallics add depth, luxury, and a futuristic feel that pairs perfectly with a space theme. Even small accents can elevate the room’s cosmic aesthetic.

Tip: Mix metallics with dark blues or purples for a balanced celestial palette.

This works because mobiles create visual interest at different heights and encourage interaction, especially for children. They also add motion and a whimsical charm.

Tip: Place the mobile above the bed or study area for a striking focal point. 

8. Starry Night Curtains

Choose curtains with stars, moons, or galaxy prints to continue the theme across the room. Dark-colored curtains with metallic prints work best for a night-sky effect.

This works because window treatments extend the theme, add depth, and control light, making bedtime cozy and dreamy.

Tip: Pair with blackout lining to enhance both sleep and the immersive night-sky look. 

9. Space-Themed Rugs

Incorporate rugs with planets, rockets, or star patterns to define space while keeping the floor cozy. Large circular rugs can even mimic planets themselves.

This works because the rug adds texture, comfort, and another layer of thematic design, pulling the room together from floor to ceiling.

Tip: Layer a neutral rug underneath if you want to tone down the print while maintaining comfort.

10. Astronaut Figurines and Wall Art

Add astronaut figurines, framed prints, or posters to your bedroom walls or shelves. These pieces can be playful, realistic, or even stylized in metallic tones.

This works because astronaut decor reinforces the space theme while giving the room a human connection to the cosmos. It also adds personality without overwhelming the color palette.

Tip: Group figurines and framed prints in small clusters on a shelf or nightstand for a curated, museum-like display. 

11. Moon-Shaped Lighting

Incorporate moon-shaped lamps or pendant lights to create a gentle, celestial glow. Choose soft white or adjustable LED lights for ambiance.

This idea works because circular, moon-inspired lighting creates visual interest while enhancing the space theme. It doubles as functional and decorative lighting, perfect for nighttime reading.

Tip: Place the lamp near a bed or desk to serve both as a statement piece and practical light source. 

12. Wall Decals of Rockets and Planets

Use peel-and-stick decals to add planets, rockets, or satellites to your walls. They’re easy to remove or reposition, making them perfect for renters or evolving decor.

This works because decals add detail and dimension without committing to paint or wallpaper. They allow creativity and personalization, helping the bedroom feel dynamic.

Tip: Arrange decals in a spiral or scattered constellation pattern for a visually pleasing, natural cosmic look.

Tip: Charge the stars with daylight or a soft lamp before turning off the lights to make them glow brighter at night. 

14. Space-Themed Bedding Sets

Invest in bedding sets with cosmic prints, galaxies, or planets in deep blues, purples, or black with pops of white and metallics.

This works because bedding anchors the room’s theme while being functional and visually striking. The patterns help unify the color palette and make the bed the centerpiece of the room.

Tip: Pair with solid-colored throw blankets or cushions to balance busy prints and prevent visual overload. 

15. Starry Projector Night Lights

Use a star projector that spins, changes colors, or even projects nebulae patterns on walls and ceilings. Some models have built-in timers and adjustable brightness.

This works because projectors create a constantly changing, immersive environment that makes the bedroom feel alive and magical. It’s especially loved by kids, teens, and space enthusiasts.

Tip: Set the projector on a low table or shelf at the foot of the bed to spread light evenly across the ceiling.

Choose shelves shaped like rockets, planets, or stars, or simply paint regular shelves in cosmic colors. Store books, toys, or decor in coordinating tones.

This works because functional storage doubles as decoration, keeping the room tidy while reinforcing the space theme. It also adds vertical interest to walls.

Tip: Mix functional items with small decorative planets or astronaut figurines for a layered, playful look. 

17. Cosmic Wall Lighting

Add LED strips or wall-mounted lights in colors like blue, purple, or soft white to mimic distant stars, auroras, or cosmic glow. Adjustable color strips work well for mood changes.

This idea works because layered lighting enhances depth and highlights key decor elements. It also gives the room a futuristic, otherworldly vibe that reinforces the space theme.

Tip: Position LED strips behind the bed frame, desk, or floating shelves for a subtle, ambient glow. 

18. Personal Space Touches

Finally, personalize your space with items that reflect your love for space: telescope, framed star maps, science books, or DIY space crafts. These make the room unique and meaningful.

This works because a themed bedroom feels more immersive when it reflects personal interests. Personal touches create connection, nostalgia, and fun, making it a space you truly enjoy.

Tip: Create a small corner display for collectibles and star maps to make them a focal point without overcrowding the room.
