Bay and bow windows project out from your home’s exterior wall, adding light, a sense of space, and a spot for a window seat.

Bay vs bow

A bay window usually has three windows: a large center unit with two angled side units. A bow window uses four or more same-size windows in a gentle curve.

What’s involved

Bays and bows need support cables or brackets, a head board and seat board, and a roof or cap over the top. Replacing an old, sagging bay is one of the biggest visual upgrades you can make to a home.
