2025 Window Treatment Trends Designers Are Lovin
If you’ve been eyeing your bay or bow windows and thinking “something’s missing,” you’re not alone. In 2025, window treatments are getting the spotlight they deserve—elevating interiors with texture, warmth, and thoughtful design. And when it comes to tricky architectural gems like bay and bow windows, the right curtain can completely transform your space.
Designers this year are embracing light, breathable fabrics, layered textures, and hardware that curves with your architecture. Whether you’re aiming for a soft, coastal vibe or something more bold and sophisticated, we’ve pulled together the top curtain styles and tips that designers can’t stop recommending for bay and bow windows in 2025.
Let’s explore the trends turning these beautiful windows into the true stars of the room.
Know Your Window: Bay vs. Bow
Before choosing curtains, it helps to understand the shape you’re working with:
- Bay windows: Usually three panels with sharp angles—great for cozy seating areas or reading nooks.
- Bow windows: Four or more panels arranged in a graceful curve—perfect for letting in loads of natural light.
Each has its charm, and with the right fabric and hardware, both can become stunning focal points.
Key Considerations Before Choosing Curtains
Here are a few simple things to keep in mind before picking out curtains for bay or bow windows.
Purpose of the Curtains
Ask yourself why you’re adding curtains in the first place. Is it mainly for privacy, to block out sunlight, or just to bring some soft texture to the room?
If you’re hoping for a natural, breezy feel, Linen curtains can be a lovely option. They give you privacy without making the space feel closed off, and they let in enough soft light to keep the room bright and pleasant.
Match with the Room’s Look
Choose curtain colours and textures that go well with your furniture, wall colour, and flooring.
Neutral colours are safe, but adding a soft colour or texture can make the room feel more balanced and finished.
Safety and Fabric Certification
Some fabrics are OEKO-TEX® STANDARD 100, Global Recycled Standard (GRS), and ECO CERT certified.
That means they’re safe for kids, pets, and the environment. This adds peace of mind if you care about health and eco-friendly choices.
Top Curtain Fabrics Trending in 2025
Picking the right curtain fabric can change how your bay or bow window looks and feels. Each fabric has its purpose, mood, and benefit. We recently discovered an online custom curtain brand called IXA Curtains. Their fabrics are certified by OEKO-TEX® STANDARD 100, ensuring they’re safe for babies, pets, and the planet. All of their curtains are fully handcrafted, and the pricing is clear and affordable.
Let’s go through some popular options from IXA Curtains that work well with these kinds of windows.
Blackout Curtains

Blackout Curtains are a solid choice if your bay window is in a bedroom or a room where you need complete privacy. These are made with thicker fabric that blocks out most of the sunlight, so your room stays darker and cooler when you need it to.
They’re also good for reducing outside noise, which helps if you live near a street or have neighbours close by. Plus, they add a cozy, closed-in feel that many people like, especially for sleeping areas.
Linen Curtains

For a softer and more breathable feel, Linen curtains work beautifully. They’re light, natural-looking, and let in just the right amount of daylight to keep the room bright without being too harsh.
Linen has a relaxed flow, and it hangs well, which looks lovely on the curved or angled edges of bay and bow windows. It’s a good pick if you want something simple, neat, and easy on the eyes.
Sheer Curtains

If you like a bright and open look, Sheer curtains are a nice option. They don’t block the light completely but soften it, which adds a gentle, calm vibe to the room.
Sheers work well by themselves in areas where privacy isn’t a big concern, like a sunroom or kitchen corner. You can also layer them with thicker curtains to get the best of both light and privacy.
Velvet Curtains

For those who like something a bit more bold and classic, Velvet curtains add a rich, warm touch. Velvet is heavier and thicker, which gives the room a more formal and finished look.
These curtains also help block cold air in winter, so they’re a good fit for colder climates or rooms you want to keep warm. If your bay or bow window is in a sitting room or a dining space, velvet can add that extra touch of style and comfort.
Outdoor Curtains

If your windows open to a patio, porch, or sunroom, then Outdoor curtains might be what you need. These are made with weather-resistant fabrics that hold up against sunlight, moisture, and wind.
They’re great for creating a little shade or privacy in outdoor or semi-outdoor spaces. You can also use them to soften strong sunlight without blocking your view.
