Bay windows are one such window type that grabs the attention of the majority. Their unique appearance is something one can’t overlook. Further, there are various types of bay window options, including those featuring tempered glass sheets for added durability and elegance.
This blog post is all about different types of bay windows, and their pros, and cons. So, let us get into it.
What Is A Bay Window?
Before we dive any further, let us first find out what bay windows are. Bay windows are basically three-dimensional windows that sit outside the house exterior. Homes with bay windows installed have a distinctive look compared to contemporary homes. Bay windows are ideal for homes with little to no room for installing a window. Further, you can customize these windows by choosing the design, glass type, and size of your choice, which may involve processes like cutting tempered glass to achieve the desired fit and finish.
Bay Windows vs. Bow Windows: What is the Difference?
Before diving into the styles, it is common to confuse bay windows with bow windows. While they look similar, they have distinct differences:
- Bay Windows: Typically consist of three glass panels set at sharp angles (usually 30, 45, or 90 degrees) that project outward from the home. They create a sharper, more geometric look.
- Bow Windows: Typically consist of four to six glass panels arranged in a gentle, sweeping curve. Because they use more panels, they are usually wider and offer a more panoramic view.

Types of bay windows
Once you know different aspects to look for while buying a bay window, it’s time to explore its different types. Here are a few different types of bay windows discussed, along with their pros and cons.
1. Oriel Bay Windows
Oriel windows are highly distinct because they do not touch the ground. Instead, they are installed on the upper floors of a home, projecting outward and supported beneath by decorative structural brackets, corbels, or masonry. Originating in medieval and Tudor architecture, they are perfect for homeowners looking to add historic, dramatic charm to their home’s upper levels.
PROS
- Adds instant historic charm and unique architectural interest.
- Saves ground-level footprint while expanding upper-room space.
- Perfect for creating cozy reading nooks in upstairs bedrooms.
CONS
- On the expensive side due to specialized structural support and installation needs.
2: Circle Bay Windows
Almost every homeowner will get the design concept of circle bay windows. As the name says, these are bay windows that are installed in a circular shape. Circular bay windows are more suited for modern homes than oriel bay windows. Additionally, for those considering the best glass for aquarium setups, circular bay windows can offer inspiration for creating a modern and unique aesthetic.
PROS
- Ideal For Modern Homes
- It Can Be Fitted With Double-hung Forms
CONS
- Installation can be a hassle
3: Bow Bay Windows
Next up, we have the bow bay windows. These windows are a mix-and-match of bay windows and bow windows. For those who are fans of both these window types, as well as interested in unique attic window types, these windows are a perfect option.
PROS
- Perfect For A Picture View Of Outside
- Unique Aesthetics
CONS
- Very Expensive
4. Canted Bay Windows
If you have ever pictured a classic bay window, you are likely thinking of a canted bay window. This is the most common and recognizable style in residential architecture. A canted window features a flat front pane with two side panes angled inward—typically at 30, 45, or 90 degrees. This timeless style is highly favored for Victorian, Edwardian, and Craftsman-style homes.
PROS
- Classic, timeless aesthetic that boosts curb appeal.
- Fits beautifully into almost any living space, especially living rooms and bedrooms.
- Provides excellent additional interior floor space for window seats.
CONS
- Requires precise structural support during installation.
5: Box Bay Windows
Out of all types of bay windows, the box bay windows are the most affordable ones. As their name highlights, these are bay windows with a boxier front. Apart from their boxy shape, other characteristics of these windows, including their compatibility with various interior wall materials and finishes, are pretty much the same.
PROS:
- Affordable option
- Enhances the house exterior looks
CONS:
- Tough To Maintain
6: Splay Bay Windows
Splay bay windows are very similar to canted windows, but with a much gentler slope. The side windows flare out at a much wider, more subtle angle (often 150 degrees). This creates a softer, more gradual transition from the exterior wall, making them a brilliant choice for transitional or mid-century modern home designs.
PROS:
- Softer aesthetic that doesn’t look overly geometric.
- Lets in a massive amount of natural light due to the wider angle.
CONS:
Does not project as far outward as a canted window, limiting space for a deep window seat.
7: Polygonal Bay Windows
As the name implies, polygonal bay windows feature more than three sides. They typically have five or more glass panels arranged in a semi-hexagonal or octagonal shape. This style bridges the gap between a sharp canted bay and a curved bow window, giving you a semi-rounded appearance without the extreme cost of curved glass.
PROS:
- Unique, high-end look that stands out in any neighborhood.
- A great, budget-friendlier alternative to circular/bow windows.
CONS:
- More window frames mean slightly interrupted outdoor views.
8: Cascading Bay Windows
A cascading bay window is a stunning, multi-story installation where bay windows are stacked directly on top of each other across two or more floors. This grand architectural feature is often seen in high-end luxury homes and historic brownstones, creating a seamless column of glass on the home’s exterior.
PROS:
- Breathtaking, luxurious visual impact.
- Floods multiple floors of your home with maximum daylight.
CONS:
- Extremely expensive; requires complex structural engineering.
What Aspects to Consider Before Buying Any Bay Window?
Now, let us find out what it takes to choose a quality bay window. Of course, there are different aspects to look for. Here are a few of these essential factors.
1: Window Style
First, you must decide which bay window style grabs your attention the most. Usually, homeowners opt for box bay windows. That’s because they are a bit more affordable. However, you can also opt for any other window style.
2: Glass Options
Because bay windows feature a massive surface area of glass, choosing the right glass type is crucial for your comfort, safety, and energy bills. Here are the primary options to discuss with your provider:
- Insulated Glass Units (IGUs): Since bay windows let in a lot of sunlight, single-pane glass will cause major temperature swings. Opting for dual-pane insulated glass (or Low-E glass) is highly recommended to keep your home warm in the winter, cool in the summer, and your energy bills low.
- Tempered Glass: Building codes often require safety glass for large, low-to-the-ground windows. Tempered glass is heat-treated to be up to four times stronger than standard glass, and if it breaks, it crumbles into dull, safe pebbles rather than sharp shards.
- Patterned or Frosted Glass: If your bay window faces a street or a close neighbor, you can still enjoy natural light without sacrificing privacy. Consider using decorative patterned glass or frosted glass on the side panels of the bay.
3: Window Frame Material
The window frame material also determines the strength and durability of your bay windows. Therefore, choosing a durable material is the best approach here. Usually, aluminum is used as a window frame material for bay windows.
4: The Operational Factor
Not all bay windows open and close in a similar manner. Also, each home’s interior has different corners and sections to install a bay window. Therefore, you should also consider this factor. In this regard, it is best to consult with an expert designer.
5: Energy Efficiency
Most of the bay windows are pretty energy efficient. However, to ensure maximum energy saving, opting for dual-pane glass panels for bay windows is best. That’s because dual-pane or insulated glass has excellent insulation characteristics. Additionally, understanding the difference between tempered and laminated glass can help you choose the right type of glass for durability and safety, depending on your specific needs.
6: The Cost Factor
The overall installation cost of each bay window varies. On average, a typical bay window may cost around $1200 to $3500 (for each window). Note that local labor charges will vary for every state. So, have a defined budget in your mind before choosing any bay window.
Final Thoughts!
So, now you know different types of bay windows along with their pros and cons. For every home, bay windows are a perfect option. Depending on your interior space and budget, you can choose any of the above bay windows. Never compromise on the quality of the glass panel. We recommend buying glass panels from a reputable glass distributor. Fab Glass and Mirror is your go-to place to order glass and mirror panels for all your needs.
