Kitchen bay windows can add charm and functionality to your cooking space. With their angled sides that extend outward, bay windows create room for extra seating, storage, and natural light. Considering adding one of these elegant architectural features to your kitchen? Read on for our favorite kitchen bay window ideas to inspire your remodel.

Benefits of a Kitchen Bay Window

Kitchen bay windows offer several advantages:

More Natural Light

The extended sides of a bay window allow more natural sunlight to fill your kitchen. Sunlight makes cooking tasks easier and gives the space a warm, inviting ambiance. For maximum sunlight, choose an unobstructed location that faces east, south, or west.

Extra Seating

The bay’s projecting form creates a cozy nook for a breakfast table or casual dining spot. Built-in bench seating lined with plush cushions provides a comfortable place to enjoy a meal or morning coffee.

Increased Storage

Beneath the bay’s seats or behind its sides, integrate drawer storage for pots, pans, and cooking utensils. Open shelving also works well for cookbooks, dishes, and decorative items.

Added Counter Space

Use the bay’s flat top surface as additional countertop area for food prep and serving. Opt for durable surfaces like granite, quartz, or butcher block.

Enhanced Views

Position your bay window above a sink or cooktop to provide views of your backyard or other attractive outdoor scenery. Frame the view with curtains or blinds.

Ventilation Options

Some bay windows can open to bring in fresh air. Casement windows on the angled sides are an ideal option. You can also add windows that crank outward above the bay.

Best Locations for a Kitchen Bay Window

When planning your kitchen layout, consider these prime spots for installing a bay window:

Above the Sink

Let ample sunlight pour over your cleanup zone by placing a bay window over the kitchen sink. Include a window directly in front of the sink for ventilation and views while washing dishes.

Seating Nook

Use a bay to create a distinct breakfast nook or dining area. Position it next to the kitchen table or build it into an empty corner. A round dining table fits nicely into a rounded bay shape.

Bump-Out Addition

For a major remodel, construct a bump-out bay that extends from your home’s exterior. This location frees up existing wall space in your layout for an uninterrupted workflow.

Near Appliances

Having natural light near appliances makes cooking more visible and enjoyable. Bays work well positioned near the stove, oven, fridge, or kitchen island.

Facing the Yard

Take advantage of beautiful backyard views by placing your bay window above the kitchen sink or range. Install blinds to control sunlight as needed.

Adjacent to Entryway

Greet guests with abundant daylight and a cozy banquette by adding a bay off the kitchen beside the entryway. Include plush cushions for relaxing as you put on shoes.

Kitchen Bay Window Styles

Kitchen bay windows come in several classic styles:

Standard Bay

This basic style has three sides – one large central window flanked by two angled windows on each side. The angles typically protrude outward between 1 and 3 feet.

Bow Bay

For a gently curved shape, choose a bow bay window. Its sides have a soft arc rather than distinct angles. Bow bays with four or more panels feel more spacious.

Circle Bay

This bay shape features a 180-degree or rounded semi-circle form. Circle bays don’t have sharply angled corners, giving them a smooth, enclosed feel.

Picture Bay

Picture bay windows have a wide, continuous top panel above angled bottom panels. This makes them feel more open and airy than standard bays.

Extended Bay

An extended bay has a central picture window flanked by two additional windows on each side. This style combine wide views with extra sunlight intake.

Slanted Bay

Slanted or polygon bay windows have angled panels that slant inward or outward. Choose slanted sides to fit the dimensions of your existing layout.

Double Bay

For a dramatic statement, install a double bay with a set of windows that jut outward in the center and sides of the wall. Opt for different shapes in each bay.

Kitchen Bay Window Design Tips

Follow these design strategies to make the most of your kitchen bay:

Match Architectural Style

Select a bay shape like rounded, slanted, or arched that complements your home’s existing architectural details. It will look seamless with the overall style.

Include Window Treatments

Dress up your bay windows with curtains, valances, or blinds that layer in softness. Opt for roll-up shades to control sunlight without sacrificing views.

Incorporate Built-Ins

Take advantage of the bay’s recessed space by adding built-in bench seating, storage drawers, or open shelving. Paint or finish built-ins to match your cabinets.

Extend Flooring

For a unified look, use the same flooring like tile, hardwood, or laminate throughout the kitchen and into the bay window area. This makes the space feel more open.

Add Architectural Interest

Frame out the bay window opening with molding or trim details that match or accent other trim finishes in your kitchen. Add paneling beneath the bay for character.

Include Electrical Outlets

Make your bay window area even more functional by installing electrical outlets. They will allow you to plug in lamps, charge devices, or use portable appliances.

Choose Views Wisely

Position the bay to frame an attractive backyard view or vibrant garden area. Limit views of unattractive objects like AC units, parking areas, or fences.

Provide Adequate Clearance

Leave enough space around the bay window seating area to allow easy access. At least 20-24 inches of clearance is ideal for entering and exiting the seats.

Finish Window Returns

Use drywall and trim to cleanly finish the interior sides of the bay window returns. Built-in storage also helps integrate awkward angled returns.

Best Materials for Kitchen Bay Windows

Durability and easy cleaning are essential for kitchen bays. Consider these ideal window materials:


Vinyl bay windows are affordable, low-maintenance, and energy-efficient. Vinyl resists moisture, rotting, and wear while insulating well. Look for heavy-duty panels.


Wood bay windows offer unbeatable aesthetics and architectural authenticity. Oak and pine suit traditional kitchens. Use engineered wood for moisture resistance and stability.

Wood-Clad Vinyl

This composite combines the elegance of real wood on the interior and low-maintenance vinyl on the exterior. Wood-clad windows emulate period design and simplify cleaning.


For incredible durability, choose fiberglass bay windows. Fiberglass resists rotting, warping, and temperature fluctuations while still looking like painted wood.


Aluminum bay windows are a budget-friendly option appropriate for many home styles. Look for insulated aluminum to prevent indoor temperature loss and condensation.

Glass Block

Use glass block windows within your bay for contemporary style and diffused light. Glass blocks also provide insulation and security while allowing in natural light.

Display Shelves

Work open shelves, cubbies, and ledges into the sides of the bay window for displaying ceramics, cookbooks, fresh herbs, and other kitchen items. Opt for glass shelving to maintain lightness.
