The best way to decorate a bay window is to match the space to its room and purpose. Add a window seat with cushions for a cozy reading nook, hang roman shades or sheer curtains for soft light control, or place a round table and comfy chairs to turn it into a dining space. The key is to keep the bay window area open enough to welcome natural light while giving it a clear function — seating, storage, plants, or a mix of all three.
Bay windows are one of the most versatile features in any house. They push out from the bay window wall, creating extra space that most flat windows simply cannot match. Whether you have a classic bay window with three windows at sharp angles or a bow window with a gentle curved shape, the decorating ideas below will help you turn that space into the room’s focal point.
Start with the purpose of the space
Before buying furniture or curtains, ask one question: what do you want this bay window area to do? A bedroom bay window has different needs than one in a living room or kitchen. Here is a quick breakdown by room:
| Room | Best use | Why it works |
| Living room | Seating area with a sofa or comfy chairs | Natural light makes it a perfect spot to relax and read |
| Bedroom | Cozy nook with a window seat and blinds | Quiet, private, and easy to control direct sunlight |
| Kitchen | Cozy breakfast nook with a round table | Morning light and a view turn meals into something fun |
| Dining room | Custom banquette or dining area with chairs | Three windows frame the table and fill the space with light |
| Home office | Desk facing the window | Daylight reduces eye strain and lifts your mood |
Once you know the purpose, every other choice — window treatments, furniture layout, colour palette — falls into place.
Window treatments that suit bay windows
Dressing bay windows is tricky because the angled or curved shape does not work with a single straight curtain rod. Here are the most popular window treatment options:
- Roman shades fitted to each panel for a clean, tailored look
- Sheer curtains that filter light without blocking views
- Floor length curtains hung from a ceiling-mounted curved track for drama
- Cafe curtains covering only the lower half, great for street-facing windows that need privacy while still allowing natural light in at the top
- Window shades in linen or bamboo for a casual, relaxed feel
- Blinds with adjustable slats for full control over direct sunlight”We often approach bay windows as an opportunity to design custom furnishings such as a built-in dining bench or window seat. Surrounding decor should be minimal and neutral so nothing competes with the window itself.” — Angela Hamwey, founder of Mackenzie & Co. interior design studio
For a bedroom bay window, consider layering. Use sheer curtains during the day and heavier floor to ceiling drapes at night. This gives you soft morning light and full privacy after dark. Match the fabric colour to your window trim for a polished look with clean lines.
If your casement windows open inward, roman shades or cafe curtains work better than long drapes because they will not get caught when you open the sash. For awning windows, any style of window treatment works well.

Build a window seat or reading nook
A window seat is one of the most popular bay window ideas for good reason. It turns dead space into a cozy reading nook, a spot to relax with a cup of tea, or even a guest bed in a pinch.
What you need for a basic window seat:
- A built in storage bench sized to the bay’s width and depth
- A 7–10 cm thick foam cushion topped with washable fabric
- Two or three throw pillows for back support
- A small side table or shelf for books and drinks
A built in storage bench is the perfect solution for small homes. Lift-up lids or drawers underneath give you hidden storage for blankets, board games, or shoes. This setup works in every room — from a living room seating area to a bedroom bay window.
If you do not want to build anything permanent, place a narrow sofa or a pair of comfy chairs facing each other in the bay. Add a small console table in the middle and you have an instant conversation area that makes the space feel intentional.

Use the bay as a dining space
A bay window in the kitchen or dining room is the perfect spot for a cozy breakfast nook. A round table fits the angles better than a square one, and it seats more people without sharp corners getting in the way.
| Setup | Best for | Space needed |
| Round table + 2 chairs | Small bay window | 100–120 cm depth |
| Custom banquette + table | Medium bay | 120–150 cm depth |
| Full dining table + 4 chairs | Large bay | 150+ cm depth |
A custom banquette along the bay window wall saves floor space and adds hidden seating storage underneath. Pair it with a couple of chairs on the opposite side. The natural light from three windows makes meals feel brighter and the room seem larger — no overhead fixture needed during the day.
Add plants and greenery
Bay windows get more direct sunlight than most spots in a house, which makes them ideal for indoor plants. Succulents, herbs, and small citrus trees do well here. Use decorative planters in different heights to add depth to the bay window area.
A few plant placement ideas:
- Line small pots along the window sill
- Hang trailing plants from ceiling hooks above each window panel
- Place a tall fiddle-leaf fig or rubber plant at one end of the bay
- Add plants on a narrow console table or floating shelf
Grouping plants at varying heights fills the negative space without blocking light. For east-facing bays, ferns and calatheas thrive. South and west-facing bays suit cacti, jade plants, and rosemary.
“Think of bay windows like the eyes of a room. You want to dress them up with beautiful treatments the same way you would eyeshadow or mascara.” — Judy Pickett, interior designer
Make a bold statement with art and shelving
The bay window wall on either side of the window is often ignored. Use it. Built in bookshelves flanking the bay turn the whole wall into a feature. Floor to ceiling shelves on both sides frame the window and draw attention to it from across the room.
Other ways to decorate the bay window wall:
- Lean framed prints on the sill for a casual gallery feel
- Hang a single large piece of art on the wall above the middle window
- Install floating shelves inside the bay for books, candles, or pottery
- Place a tall floor lamp at one corner to light the space at night
In a living room, this approach turns the bay into the room’s character — a creative focal point that changes with the seasons. Swap out items on the shelves a few times a year to keep things fresh.
Tips for small bay windows
Not every bay is wide enough for a table or a full seating area. A small bay window still has plenty of potential:
- Use it as a plant shelf or herb garden
- Place a single armchair and a floor lamp for a reading nook
- Add a narrow console table with a vase and a few books
- Install a fold-down desk for a compact home office
- Keep the space open and let the light do the decorating
Leaving some negative space is fine. Not every corner of a house needs furniture. Sometimes the light streaming in through a well-made picture window or fixed window is decor enough on its own.
Get the window itself right first
All the interior design ideas in the world will not help if the window itself is drafty, fogged, or hard to open. If your bay windows are older or losing their seal, cold air and condensation can ruin cushions, warp wood furniture, and fade fabrics faster.
Before spending money on bay window decor, check the condition of the glass and frames. Triple-glazed, ENERGY STAR™ certified vinyl windows with Low-E coatings and warm-edge spacers will keep your bay comfortable in every season. They block UV rays that fade upholstery, reduce outside noise, and keep heating costs down through harsh Canadian winters. If your bay needs an upgrade, a well-built bay window replacement is the best first step before any decorating project.
Modern casement window types and slider windows are also popular for bay configurations, depending on your ventilation needs and the style of your house.

Frequently asked questions
What is the best furniture for a bay window?
A window seat or built in storage bench is the most popular choice. For larger bays, a round table with chairs or a small sofa works well. Match the furniture scale to the depth of your bay window area.
How do you dress a bay window without curtains?
Roman shades, roller blinds, or plantation shutters all work without curtains. You can also leave the window bare and let decorative planters, artwork, or a polished window trim do the talking. This suits modern homes with clean lines.
Can you put a sofa in front of a bay window?
Yes, a low-profile sofa fits well in a large bay. Keep the back height below the window sill so it does not block natural light. This turns the bay into a cozy seating area that feels like part of the living room.
How do you make a small bay window look bigger?
Use sheer curtains or light-coloured roman shades to keep the space bright. Avoid heavy, dark fabrics. A mirror on the bay window wall opposite the glass reflects light and gives the illusion of more depth.
Are bay windows energy efficient?
Modern triple-glazed, ENERGY STAR™ certified bay windows with Low-E coatings and argon gas fills are very efficient. Older single-pane bays can lose heat fast, so upgrading the glass and frames is worth it before decorating.
