Many homeowners incorporate bay and bow windows into their home design to improve natural lighting and create a nook-like space for dining, reading, or enjoying a panoramic view of outdoor scenery. These spaces are often one of a kind and require different numbers of panels, so costs can rise quickly. Expect costs to vary based on factors like the scope of your project, window type, number of panels, size of the window, frame material, and glass type. Many window companies will even custom build bow windows to fit your space just right. However, their complex installation typically requires professional labor, adding to their high price. We recommend simpler, more affordable windows if bow windows are outside your budget.
The biggest factor affecting bow window installation cost is the window frame material. Cory Buescher, a virtual handyperson expert for Frontdoor in Memphis, Tennessee, said that the window material and brand you choose directly affect the price of your bow window. Vinyl windows are a budget-friendly option that provides the best value for your dollar. “Vinyl windows offer a cost-effective solution without compromising on quality or aesthetics,” said Rick Andronicos, a general contractor of UnitedBuilders based in Rancho Cucamonga, California.
In this article, we’ll dig into all of the factors that can affect the cost of bow windows. Using extensive cost data research and expert advice, we’ll offer tips on how you can save on bow windows and what you can expect to pay for them.
Average Cost of Bow Windows
Our research found that bow windows start at $1,300 but can cost as much as $6,000, depending on factors such as the frame material and glazing options. The prices below reflect average cost ranges for bow windows. These estimates will fluctuate significantly based on the specifics of your project.
| Cost Range | Average Cost Range |
| Low-End Cost Range | $1,300–$2,000 |
| National Average Cost Range | $2,000–$4,000 |
| High-End Cost Range | $4,000–$6,000 |
What Factors Affect the Cost of Bow Windows?
The cost of bow windows varies greatly and depends on factors such as the project scope, window types, number of panels, size, and frame material. Let’s explore each of these areas in more detail.
Cost of Bow Windows by Project Scope: Replacement or New
The cost of bow windows is usually the biggest concern homeowners have. Replacing an existing bay window or bow window gives you a price break. It’s far cheaper than installing a new one—often saving you thousands of dollars. This is especially true if you pick a replacement window of a similar size, material, and structure to your current bow window. Adding new bow windows sometimes requires structural modifications to your home’s siding or window opening. This accounts for a higher installation cost.
| Project Needs | Low-End Cost | High-End Cost |
|---|---|---|
| New construction bow windows | $2,500 | $5,000 |
| Replacement bow windows | $1,300 | $3,500 |

Cost of Bow Windows by Window Type
Bay and bow windows are structures consisting of several smaller windows. Those individual window panels can be of various styles: double-hung, casement, or picture windows. Many bay windows feature a fixed centerpiece with operable end panels for optimal functionality. Many bow windows feature single or double-hung windows that don’t protrude outward when open.
The type of windows you choose for your bow window affects the cost. Fixed windows, also called picture windows or fixed lites, are often inoperable—large windows that don’t open. Homeowners tend to use them as the center windows of bay and bow models because they provide an unobstructed view of outdoor scenery. Meanwhile, double-hung windows have two movable sashes that slide up or down to open. The sashes overlap when the window is open, making these windows excellent choices for bow windows with inner space constraints.
If you want excellent ventilation, it’s best to use casement windows as bow windows. They open outward, like a door, via an easy-to-use hand crank. The opening allows air to flow through the entire window. Consider these typical cost ranges when choosing the windows for your project:
| Type of Windows | Low-End Cost | High-End Cost |
|---|---|---|
| Fixed lites | $2,320 | $3,085 |
| Double-hung windows | $1,725 | $2,934 |
| Casement windows | $3,270 | $5,358 |

Cost of Bow Windows by Number of Panels
The number of window panels you want also plays a role in the final price of your bow windows. Simpler designs, such as box bay windows, will be less expensive than angled bay windows with four or more sections. Box bay windows have three panels that form a box-shaped nook. Their style lacks the curvature and panel count of angled bow windows, making it a more affordable option. Angled bow windows have up to six lites that form a gentle curve. This more intricate styling requires more material and means a complex installation, yielding higher prices.
According to our research, the number of panels in your bay or bow window affects price in the following ways:
| Number of Window Panels | Average Cost Range | High-End Cost |
|---|---|---|
| 3 | $1,600 | $2,300 |
| 4 | $2,015 | $4,200 |
| 5 | $3,500 | $3,900 |
| 6 | $3,745 | $5,270 |
Trying to decide between a bay or bow window? Listen to this Today’s Homeowner Podcast segment where Danny discusses the benefits and drawbacks of both options:
Cost of Bow Windows by Size
Some bow windows span the height of entire walls, while others integrate as smaller, shelf-like features. Larger bow windows cost more than smaller ones because of the additional materials and labor required for building and installation.
The figures below reflect how bow window costs fluctuate by size:
| Bow Window Size | Average Cost |
|---|---|
| 7’ X 4’ | $1,625 |
| 8’ X 4’ | $1,650–$2,125 |
| 8’ X 5’ | $2,770–$3,370 |
| 9’ X 5’ | $2,370–$4,125 |
| 10’ X 6’ | $3,370–$4,645 |
| 12’ X 6’ | $3,745–$5,270 |
| 14’ X 3’ | $4,220 |
| 14’ X 6’ | $6,950 |
Cost of Bow Windows by Frame Material
The material you pick for your bow window frames dramatically affects the overall cost. Vinyl and wood are the most common frame materials for bay and bow windows, with vinyl being more affordable. With vinyl, you’ll get excellent energy efficiency and low-maintenance durability. It’s the least expensive material and comes in a wider variety of colors. Vinyl is also resistant to warping, rotting, and rusting, giving it added appeal for homeowners in wet climates.
Aluminum is another option for bay and bow windows, popular for their weather resistance and low-maintenance strength. However, these frames aren’t the best option if you want energy-efficient windows due to their conductive nature, according to Andronicos. Aluminum-clad wood frames are more popular for added energy efficiency because solid aluminum has poor insulation.
Wood is durable, versatile, and highly insulative, making it a top choice for homes in cold climates. Although more expensive, wood is usually more durable, especially if you need to make structural changes to accommodate your bow window. However, wood frames require more long-term upkeep than aluminum or vinyl, a drawback for some buyers.
Here are the costs for four-panel casement bow windows with different frame materials:
| Window Frame Material | Low-End Cost | High-End Cost |
|---|---|---|
| Vinyl | $2,400 | $4,500 |
| Aluminum | $2,425 | $5,270 |
| Wood | $3,575 | $5,200 |
Cost of Bow Windows by Glass Type
Window companies offer bow windows with standard glass options alongside various upgrades. For example, you can equip your bow window with low-emissivity (Low-E) coating to reduce the amount of solar heat entering your home. Consider tempered glass if you want tough glass that won’t break into large, sharp shards.
Some glass customization options come standard, depending on the number of glass panes you pair your bow windows with. With double-pane and triple-pane windows, manufacturers fill the spaces between each glass pane with gas to increase the window’s energy efficiency.
Our team spoke with Gal Cohen, the field area manager of JDM Sliding Doors in Fort Lauderdale, Florida. According to Cohen, laminated glass is the priciest glass upgrade, from $1,800 to $3,200 per window, while tinted options are the most affordable at $1,000 to $2,000.
| Glass Upgrade | Cost per Window |
|---|---|
| Tinted glass | $1,000–$2,000 |
| Argon gas-filled | $1,200–$2,500 |
| Low-E coating | $1,200–$2,500 |
| Krypton gas-filled | $1,500–$3,000 |
| Tempered glass | $1,500–$3,000 |
| Laminated glass | $1,800–$3,200 |

Installation Costs for Bow Windows
Labor costs are another factor affecting bow window replacement costs. According to Heinemann, his company charges between $300 and $800 per bow window installation. Heinemann added that installing windows costs $50 to $100 an hour.
We interviewed Robert Schindler, the vice president of Window World, who is based in North Wilkesboro, North Carolina. He said window installer rates depend on a project’s complexity. “[Installation costs] can also vary based on the contractor’s experience,” he added.
Structural Work Costs for Bow Windows
The final factor influencing bow window prices is the structural work of installing bow windows. “[For] bow and casement windows, [the contractor] needs to consider the building’s structure and how they fit with the outside wall,” said Mark Waddell, the installation and application manager of Cary, North Carolina-based Cornerstone Building Brands.
Additional Costs of Bow Windows
As one of the more complex window options on the market, bow windows include several costs beyond size and material considerations. You should account for installation fees, structural work, and other customizations when you select your new window(s). We’ve outlined these prices to help you avoid surprises when you order your windows:
- Window glazing: The glass you pick for your bow window also affects the price. The prevailing option for residential windows is double-pane glass, which ranges from $10 to $20 per square foot. Premium options like triple-pane glass can cost $40 or more per square foot.
- Added features like window seats, mullions, awnings, and roofing will raise your bow window costs. Although these features are optional, they can improve the return on your investment—and how much you enjoy your new windows. Still, you should factor in the hundreds or thousands of dollars they’ll add to your bill.
How To Save Money on Bow Windows
Bow windows are a high-end custom window design that will cost more than smaller and simpler builds. However, you can save on a bow window project by following these tips.
Request Multiple Quotes
Every expert we spoke with recommended contacting several companies for quotes before deciding on a specific window brand. Schindler suggested pulling quotes from window suppliers and installation companies to see which provides the most value for your investment.
Search for Discounts and Incentives
Many window companies offer promotional discounts on their windows throughout the year, so waiting for a promo could benefit you. Federal and state-level rebates and incentives, such as Energy Star’s windows and skylight tax credit, can lower the cost of bow windows.
Waddell suggested considering financing your bow windows. “This is often an attractive option, especially because the cost of the project can be offset by the energy savings the windows can offer,” he said.
Use More Affordable Materials
Although it may be tempting to purchase the flagship wood bow window, you can probably purchase a similarly equipped vinyl bow window that costs less while maintaining the aesthetic you want.
Additionally, Jung recommended considering factory-assembled bow windows to save even further. “[These allow] for easier installation and are custom-manufactured for a precision fit for virtually any opening,” he said.
Professional Vs. DIY Costs
Based on our conversations with experts and our research, we don’t recommend installing bow windows yourself unless you are a skilled contractor. Bow windows are large and typically require structural modifications to your home, requiring expertise and special tools to perform the job correctly.
Bay and bow windows are often load-bearing, which means they must support your home’s roof, foundation, and exterior walls to prevent them from buckling. Installation can involve adding support beams, drywall, insulation, and additional siding materials to your home—a more complex process than for a standard window replacement.
Although DIY installation may save on labor costs and brand overheads, you risk damaging your home or installing windows incorrectly, potentially causing higher energy bills, water damage, or structural damage down the road. In many cases, the cost of an improperly installed bow window will far exceed what you saved by attempting the project yourself. “While it may seem tempting to handle installation yourselves, professional installation ensures windows are fitted correctly, preventing potential issues and additional costs in the future,” Schindler said.
Additionally, if you install your bow windows yourself, you risk paying for any repairs that could otherwise be under a contractor’s installation warranty. Reputable companies not only provide window material and labor warranties, but they’ll complete the job quickly.

What Are the Benefits and Drawbacks of Bow Windows?
Bow windows provide a pleasing view from inside and outside your home, which can preserve the look of historical residences, such as Victorian-style homes. However, their high price and extensive installation requirements may not suit everyone.
Pros of Bow Windows
- Add functionality to your interior space
- Increase your home’s curb appeal
- Let in more natural light than standard windows
Cons of Bow Windows
- Cost more than other window styles

The Cost of Bow Windows Vs. Other Window Types
Bay and bow windows cost more than other window types for two reasons. First, they require you to install multiple windows at once. Second, their out-bowing structure requires additional architectural work and installation time, which will cost more than a standard window project.
Account for these differences before committing to a bow window. If you aren’t determined to add space and a panoramic view to your home, a less expensive window style might better suit your budget.
| Window Type | Low-End Cost | High-End Cost |
| Storm | $100 | $400 |
| Single-hung | $200 | $400 |
| Double-hung | $430 | $915 |
| Casement | $440 | $950 |

FAQs About Bow Window Costs
Bay and bow windows add resale value for homes because they provide additional lighting, beautiful views, and extra square footage. Those with operable side windows and energy-efficient glass add more value by increasing the structure’s overall functionality and money-saving benefits.
Bow windows are almost always more expensive than bay windows because they include more materials. Bow windows have more panels (lites) than bay windows, so they require more windowpanes, installation work, and structural updates than their three-paneled counterparts.
Window seats can be as simple or ornate as you desire, so their costs vary greatly. DIY window benches can cost anywhere from $200 to $400, while custom upholstered models can exceed $2,000. Consider installing a seat at the same time as the window for potential cost savings and project efficiency. A seat for your bay or bow window is a charming and functional addition that will enhance your enjoyment of the space.
Many bow windows may come with warranties. Our team reviewed the best window companies using our rating methodology, which considers the length and quality of a company’s window and installation warranties.
Bow windows generally require more maintenance than other window designs, largely due to the supporting structure housing the windows. According to Waddell, the installation and application manager of Cary, North Carolina-based Cornerstone Building Brands, the structure built on your home’s exterior wall needs additional upkeep to protect it from weather deterioration.
Roy Neely, another virtual handyperson from Frontdoor that we spoke with, recommended checking the window’s structural supports and surrounding walls periodically to help prevent long-term issues.
The frame material you purchase influences the type of maintenance you need to perform. Neely said that wood bow windows require sealant or paint to guard against weather damage. Aluminum, vinyl and fiberglass frames generally require less maintenance than wood frames.
