It can cost anywhere from $100 to $2000 per window, depending on the design and size of the window. Most stained glass artists require a deposit upfront and then the balance is due when the pieces are completed. You will also need to factor in the cost of installation, which may be an additional fee charged by the artist or done by a professional glass installer.

It largely depends on the size and intricacy of the design, but typically custom stained glass can range in price from around $100 to $1,000 or more. When pricing out a custom stained glass project, it's important to keep in mind that you're not just paying for the cost of materials. The artist who creates your piece will also need to factor in their time and labor costs. So if you have a very complex design or a large window to fill, be prepared to pay accordingly. That said, there are a lot of talented stained glass artists out there who will work with you to create something truly unique and special within your budget.
