Bow Window Vs. Bay Window: The Basic Design Difference

A bay window usually has three sections, most often a large center unit flanked by two smaller angled units. That creates a sharper projection and a more pronounced nook inside the home.

Performance, Cost, And Installation Trade-Offs

Signs One Style Is The Better Fit

The room usually tells you what it wants. A bay can anchor a front living room or breakfast nook. A bow can make a sitting room feel wider and less boxed in.

• Do you want deeper interior space or a softer exterior curve?
