So much to love here!!
From the outside of the house this room is part of a multisided turret. Inside, the large tub is set into the turret with windows that are almost two stories high. I believe at the very top of the windows are flat cornice boards with the long double cascades coming out from underneath. Note the beaded trim. So pretty for catching the light, just like the crystals on the chandelier. The pleated shades cover the bottom windows to provide the necessary privacy. The flat upholstered panels marry the top and bottom sets of windows and provide a lovely focal point. What a great idea to cover an otherwise unsightly and boring expanse of white wall, and to make the whole space cozier.
I also love the tile on the tub steps and the way the whole space was styled with plants and candles. If I got in that tub, I would never want to get out!
