Great idea for hiding the TV could work in any decor Fireplace or not! A sliding wall above the fireplace (a ventless model from Hearth Cabinet) conceals the television. Hide the TV in a variation on this theme?
This could work in a tiny bathroom. Love the tiled floor/painted wall combo and the fact that the tiles in the shower match the wall colour but are different from the floor. The niche for storage works well for us too.
