Grunge is a darker aesthetic mostly associated with teenagers, punk/ rock bands, an inclination toward darker colors, and isolation or moody behavior. If you are into the grunge look, then these are some ideas to inspire your grunge room decor.
Go for dark walls
Since this aesthetic is all about darker colors, you can go for black or grey walls in your bedroom. If painting the whole room feels like too much or the size of the room is too small, consider going for a dark accent wall.
Add mood lighting
The grunge aesthetic is moody and that must be reflected in your room decor if you are going for this look. Consider adding mood lighting by using neon-colored lights or warm string lights.
Fill up walls with posters or graffiti
Let your room speak your personality and incorporate all your favorite artists and bands by putting up posters or doing a graffiti wall. You can also create a photo collage gallery wall for the perfect teenage grunge aesthetic.
Decorate with vintage vinyl records and old cassettes
Since this aesthetic became most popular in the mid-80s, decorating your room with old vinyl records and cassettes is a great way to create a grunge aesthetic room.
Put up a tapestry
Add a tapestry to the wall to get that bohemian, laid-back vibe. You can hang it over the wall above your bed.
Display your clothing/shoes for an added grunge look
If you are trying to create a grunge room, chances are you are into grunge or dark fashion styles too like goth or e-girl. Consider displaying your fashion style in your room like on clothing racks or shoe racks. This would instantly add all the dark and moody colors and also add an edgier look.
Go for a metal bed frame
You can go for a bed with a metal frame as it looks more minimal and industrial. Also, materials like metal or distressed wood are perfect for a grunge room.
