Most bay windows are treated as one continuous window when designing a valance/top treatment.
Sunshine Drapery® specializes in creating a bay window treatment–on a board or decorative pole–that fits properly. We send a professional drapery installer to your home and construct the angle measurements on site. These measurements are given to our seamstresses in our designer workroom in Maryland Heights. The same installer is responsible for installing the completed window treatment.
In terms of privacy, each window within the bay is typically treated separately. Blinds or shades for each window will operate individually. Almost any custom window treatment style can be made for your bay window.
