Every project starts with a free in-home measurement and a written quote on the spot.
What is a bay window?
A bay window is one of the best ways to open up a room without adding on to your house. It pushes out from the wall in three window units. The center unit is a picture window that sits parallel to the wall and gives you the clearest view of your yard. The two side units sit at an angle of 30 or 45 degrees and are usually double-hung windows or casement windows that open for airflow. Because a bay window juts out, it also creates a built-in ledge inside the house. A lot of Kentucky homeowners turn that ledge into a window seat or a reading nook.


What is a bow window?
A bow window is similar to a bay in that it also extends out from the wall. But instead of three units at angles, a bow is built from four, five, or six window units of the same size. They form a gentle curve instead of sharp angles. Most bow windows use casement side units that open for ventilation, with an optional picture window center for an unbroken view. The curve gives you a wider panoramic view than a bay and a softer look from outside. Bow windows are a popular choice for lake homes around Lake Barkley, Kentucky Lake, and Land Between the Lakes.
What is a good location for a bow or bay window?
If your home already has a picture window, that opening is usually a good candidate for a bow or bay. Every window we install is custom-made to fit your exact opening, so there are rarely structural changes needed. We will check your wall, soffit, and roofline during the free in-home visit. Most installs also give you the option of an overhanging roof or an integrated roof assembly so the unit looks finished from outside.
Common install spots in Kentucky homes: living rooms, dining rooms, primary bedrooms, lake-facing back walls, and kitchens above breakfast nooks.

Bay vs Bow Window – Which is Right For You?
Most homeowners want a quick way to decide between a bow and a bay before they call. Here is the short version:
- Shape: Bay = 3 panels at angles. Bow = 4 to 6 panels in a curve.
- Wider view: Bow gives you a fuller panoramic view.
- More interior space: Bay, because the angled sides create usable floor space for a seat or shelf.
- Cost: Bow usually costs more because it has more individual window units.
- Looks: Bay feels modern and clean. Bow feels classic and elegant. Both add curb appeal to any Kentucky home.
Best room: Bay works great in bedrooms and dining rooms. Bow is a showpiece for living rooms and lake-facing rooms.

FAQs
What is the difference between a bay and a bow window?
A bay window is built from three panels with angled sides (usually 30 or 45 degrees). A bow window is built from four to six equal-size panels that form a smooth curve. Bay windows give you more usable interior space like a window seat. Bow windows give you a wider panoramic view.
What is a window that juts out from the house called?
A window that projects out from the wall of your house is either a bay window (if it has three panels with angled sides) or a bow window (if it has four to six panels that form a curve). Both types add floor space inside and curb appeal outside.
How much does bow or bay window installation cost in Kentucky?
Cost depends on size, panel count, frame finish, and glass package. A 3-panel vinyl bay window in a standard size starts in the lower price tier. A 5 or 6-panel bow window costs more because of the extra units. Add-ons like stainable oak, insulated seat boards, a shingle roof, and triple-pane glass add to the base.
