The Cost of Bay Windows By Type
The type of bay window may impact its installation cost, and here is why. Basic, three-window models are usually less expensive than elaborate designs featuring more windows or custom shapes as they require less time and effort to be mounted. Additionally, windows that open, whether through double-hung or casement styles, will generally be more expensive than fixed ones. Let's explore the average bay window installation costs for each type of bay window in 2024.
Oriel Bay Windows
These units represent a projecting structure supported by brackets that offers a decorative touch to the facade. Unlike standard bay windows, they do not extend all the way to the ground. Instead, they're structured to project from the upper levels of a building, supported by corbels, brackets, or similar projections. This unique design allows them to be installed on higher floors of your home, broadening the scope of rooms where you could potentially add a bay window. The cost of installing a new bay window of oriel type ranges between $1,600 - $3,750 per unit.
Full Bay Windows
Also called canted, this classic type of bay window completely extends from floor to ceiling. Full bays have a three-window design and come outward from the room, providing panoramic views and more interior space. A setup of these windows provides ample sunlight into the room while allowing for ventilation from operable side windows. The downside of full bay windows is that they can only be installed on the first floor. You should expect to spend from $1,500 to $2,750 for bay windows of this type.
Box Bay Windows
Square or rectangular bay windows are designed in a box-like shape and come with a flat front that creates a cozy nook and maximizes natural light. They typically consist of three window sections configured in a manner that forms a three-sided square or rectangular projection from the house's exterior wall. The central unit is usually a fixed, large pane of glass, while the side ones can be chosen to either be fixed or operable. The square bay window cost varies from $2,650 to $4,550 per unit.
Circle Bay Windows
Also known as the bow ones, these windows comprise four or more glass panes that are equal in size and create a rounded appearance on the home's exterior, forming a 'circle' shape. Architecturally, circle bay windows can be a striking feature, adding depth and dimension to the façade of a home and extending the interior space. These are some of the costlier windows in our days. If equipped with venting units with a wooden frame and low-E glass, they may cost up to $6,000 per unit.

The Cost Of Bay Windows By Frame Material
The material used to construct the bay window frame impacts its appearance and installation cost. Generally, pricier frame options like wood and fiberglass come with a more generous offer of advantages, including paramount ones like longevity and enhanced insulation. Read on to discover how frame material affects the average bay window replacement cost.
Vinyl Bay Windows
This relatively inexpensive material resists moisture and decay, requiring little maintenance. Vinyl frames come in different color schemes but cannot be painted or stained like wood. That means they are harder to match with the home's interior. If you want to skimp on installing new bay windows, a vinyl frame is where you can cut the cost. The cost of these windows lies in the range of $590 - $2,350.
Wood Bay Windows
Wood is easily customizable compared to wood and aluminum and boasts great aesthetic and insulation properties, matching different interior and exterior designs. This material, though, requires more thorough maintenance than its counterparts and cannot offer the same level of energy efficiency as, for instance, fiberglass. The new bay window cost made of wood falls in the range of $890 and $3,250.
Aluminum Bay Windows
Aluminum frames are selected for their lightweight and resistance to warping and bending. Plus, they are not afraid of rapid temperature drops and can keep their initial form and appearance for years to come with little to no maintenance. The drawback of aluminum bay windows is that they easily conduct heat, worsening the home's energy efficiency and raising electricity bills. If your choice falls upon this frame option, expect to spend from $400 to $1,950 per unit installed.
Fiberglass Bay Windows
While lacking the aesthetic value of wood, fiberglass offers unmatched weather resistance and durability. It's also a great insulator, helping to lower utility bills. The good news is that fiberglass can mimic the natural look of wood, complete with the grain texture. However, these advantages come at a premium. Installing a fiberglass bay window can cost between $630 and $3,100 per unit.

Add-Ons Affecting Bay Window Prices
Several add-ons can enhance the functionality and aesthetics of your bay windows. However, keep in mind that each additional feature comes with its own cost. Consider the following popular add-ons and their average prices:
Depending on the local climate pattern and your monthly spending on utility, you may want to enhance your home's energy efficiency by installing high-performance glass like low-emissive, insulated, or tinted. These pane options will help you to improve insulation and reduce energy consumption, reducing heat transfer and blocking harmful UV rays. Please note that installing energy-efficient glass increases the bay window cost by up to 25%.
This clear coating is applied to bay panes to block harmful UV rays. It does not impede the view or significantly reduce the amount of natural light that comes in. UV coating is often used with other energy-efficient window technologies, like Low-E coatings. Depending on the coating type and the window size, you can expect to spend from $800 to $3,700 per unit.
Window trims refer to the decorative and finishing parts that frame a window. They serve both functional and aesthetic purposes, protecting the window's edges and adding design accents to your home's style. Installing trims on a bay window can increase overall installation costs by $300 - $1,100 per unit.
Bay roof addition
The roof of a bay window is a critical component that can add architectural detail and protection from weather elements. Bay window roofs can be flat, gabled, hipped, or made to match the existing roof line. They can be constructed from various materials, including metal, asphalt shingles, and copper. Depending on the material, bay window roofs may cost $3 to $30 per square foot.
Here is how bay window replacement cost might be affected by different add-ons:
