Change interior doors in the apartment, is it better to stick with wood or try glass doors?

It really depends on what you need in each room, because an interior bedroom door isn't the same as a bathroom or living room door. Wood is still the most versatile option: it insulates sound well, gives you complete privacy, it's easy to repair if it gets damaged, and it works with pretty much any decorating style. Glass doors are more modern and make spaces look bigger and brighter, but they have some clear limitations.

Glass works great in hallways or separating open spaces (like living room-kitchen), but in bedrooms or bathrooms you'd lose privacy unless you use frosted or translucent glass. You also have to be realistic: glass is more fragile, it gets cloudy easily, and if you have pets or small kids banging into it, the damage costs way more to fix than a dent in wood. Plus, the sound insulation is worse, so if someone's watching a movie in the living room while another person's trying to sleep, you're definitely going to hear it a lot more.

My advice: keep wood in bedrooms and bathrooms, try glass in the hallway or between the living room and kitchen if that bright, airy feeling appeals to you. That way you get the best of both without sacrificing what really matters, which is comfort in your private spaces.

How much natural light do you have in those rooms? Because wood is the safe choice, but I'd say glass isn't an all-or-nothing decision - a lot of times the best approach is to mix them. Glass doors work well in hallways or between spaces you want to feel connected, but in bedrooms or bathrooms privacy is a real concern, so wood is still the practical option there. What I think the previous answer doesn't mention is that glass might look modern but then you realize it gets dirty constantly, scratches easily, and if you've got kids or pets at home it's a nightmare. My suggestion: keep wood where you need soundproofing and privacy, and if you want to refresh the look, you can change the type of wood or the finish instead of taking a chance on material that's just going to give you more headaches down the road.

What's your budget, and how much do you care about long-term maintenance? Because that's where the real decision between one option and the other actually plays out.

Look, wood is the classic choice and it works fine, but glass has a point in its favor that nobody mentions: it's brilliant if your flat is small or dark. A tempered glass door (way better than regular glass, which breaks and is a nightmare) opens up spaces visually without sacrificing structure. The trick that actually works is mixing them by zone: glass in the living room and kitchen so light flows through, wood in bedrooms and bathrooms for privacy and thermal comfort.

The practical thing I've seen work really well is putting gray or black aluminum frames with frosted or satin glass instead of pure transparent glass. You get the best of both worlds: it keeps visual privacy, lets light through, and looks way more contemporary than standard wood. They're easier to maintain than wood (just a quick wipe with a cloth and you're done), though I'll admit if your flat is old and you want to keep the original aesthetic, modern glass doesn't fit. In that case, wood is your option, but pick tones that match what you already have.
