Discussing How Much Bay Windows Cost

For an average size home (2,330 square feet.), the cost for a bay window ranges from $150 to $2,000 or more. The price varies greatly based on size, style (casement or double-hung), material, and manufacturer. Costs typically include the window, labor, and trim.


The size of a bay window varies depending on whether it is in the kitchen, master bedroom, living room, or office. For example, kitchen bay windows and master bedroom windows in an average size home are smaller than windows in the living room. A large bay window for a living room will start at $1,000 to $1,500. A small bay window may be as little as 2 x 4 feet, in which case, the cost will start at $200 to $300. If you live in a larger than average size home, the largest bay window models can cost up to $6,000 or more.


Because casement windows offer solid construction, maximum energy efficiency, and open wider than any other window, they’re more expensive than double-hung windows. Casement windows have mechanical pieces that are used to crank the window outward. This also adds to the price, making them more expensive than double-hung windows, which are typically equipped with just a simple handle.

Type of material

The type of material plays a major role in determining whether or not you will pay several hundred dollars for your windows or $2,000. Bay windows are available in aluminum, cellular PVC, fiberglass, steel, vinyl, and wood. Steel and wood are the most expensive materials, followed by fiberglass and aluminum. Cellular PVC and vinyl are the least expensive materials for bay windows.


Although there are hundreds of bay window manufacturers to choose from, several manufacturers are the most popular:

  • Andersen
  • Marvin
  • Pella

Each company offers pre-made bay windows and they create custom windows. Custom windows are more expensive.
