Bow Window vs. Bay Window: What’s the Difference?

The Basic Shape Tells You A Lot

How Each Style Changes A Room

The visual effect is the main reason homeowners choose one over the other.

Because the center panel is often larger, bay windows can make the glass opening feel bold and intentional, especially in traditional or craftsman-style homes.

Structure, Installation, And Cost Differences

The way these windows are assembled affects installation time, support requirements, and how much the project costs.

Bay windows usually require more structural attention because of the way the angled sections project from the wall.
