The Mayns had a bathroom window that needed covering, and there was no room inside the bathroom to add shades or blinds.
We drilled through the wall to set up a drawstring inside of the bathroom window connected to the new external shades’ roller outside of it. We hung a dark gray blackout sheet from the roller to protect the customers’ privacy and keep out the sun. We lined the inside-facing part of the external shades with nylon so that they won’t be damaged by water when the window is open.
