What is a Bay Window? Benefits, Costs & Styles for Washington Homes
What is a Bay Window?
If you have ever admired a home with a window that extends outward, creating a cozy nook inside and a striking look outside, you have likely asked yourself, what is a bay window? A bay window is a three-section window type that projects outward from the wall of a house, usually forming a square, polygon, or angled shape. This design not only allows more natural light into the room but also adds usable interior space and a touch of architectural elegance.
For homeowners in Washington, bay windows are especially popular because they maximize daylight during long winters, frame beautiful outdoor views, and create charming spaces indoors. At Builders Service Company, we have been installing bay windows and replacement options for decades, bringing homeowners across Seattle, Tacoma, Spokane, and beyond both beauty and functionality.
Understanding Bay Windows in Washington Homes
When people search for what is a bay window, they often want to know more than just a definition. Bay windows originated in English architecture during the Renaissance and became a hallmark of Victorian and Tudor homes. Today, they are just as popular in modern and contemporary houses.
In Washington, homeowners often choose bay windows because they:
-
Capture more sunlight, brightening homes during gray months.
-
Provide panoramic views of scenic neighborhoods, lakes, or evergreen landscapes.
-
Add architectural character to homes in Seattle’s historic districts or new builds in Bellevue and Kent.
Different window types are available, but most Washington homes feature angled bay windows, garden bays in kitchens, or oriel-style designs in older houses.
Bay Window vs. Bow Window – What’s the Difference?
What makes a bay window unique
A bay window typically includes three sections: a large picture window in the center flanked by two smaller panels at angles of 30, 45, or 90 degrees. This angular projection makes the room feel larger and draws in more light.
How bow windows differ
A bow window curves outward with four to six panels, creating a rounded, elegant look. Bow windows are often larger than a traditional bay and may cost more because of added structural needs.
Which is better for Washington homes?
For Washington homeowners wondering what is a bay window compared to a bow window, the answer depends on style and budget. Bay windows are often the more practical choice because:
-
They cost less to install than a bow window.
-
Their sharp angles fit better with traditional craftsman and modern Northwest architecture.
-
Their side casement window panels allow flexible ventilation.
Benefits of Bay Windows for Washington Homeowners
Bay windows are not just beautiful, they are functional investments.
More natural light and wider outdoor views
Bay windows angle outward, allowing light from multiple directions. This is ideal for homes in Everett, Olympia, or Tacoma where natural light can brighten otherwise dim rooms.
Extra interior space for seating or storage
The extended ledge can be transformed into a reading nook, bench seating, or decorative shelving, adding both comfort and functionality.
Boosting curb appeal in Washington neighborhoods
From Bellevue to Federal Way, a bay window instantly enhances the architectural appeal of a home, making it stand out.
Increasing resale value of your home
Updated window types like bay and bow windows are among the features that increase property value in Washington’s competitive housing market.
Common Styles of Bay Windows Available in Washington
Box bay windows
Compact and traditional, a box bay window forms a rectangular extension. Perfect for kitchens or dining rooms.
Oriel bay windows
Mounted above the ground floor and supported by brackets, this type is common in older, historic homes across Seattle and Spokane.
Circle bay windows
Rounded with a softer edge, circle bay windows bring an elegant architectural feature to living rooms or master bedrooms.
Garden bay windows
Typically found in kitchens, these small bays are designed with shelves for herbs and plants, ideal for Washington gardeners.
What Are the Signs You Should Replace Your Bay Window?
Even the most durable windows eventually need replacement. Look for these signs:
-
Drafts or poor insulation raising your energy bills.
-
Condensation or fog between glass panes.
-
Cracked frames or outdated designs.
-
Windows that no longer open or close properly.
