It’s not even a question when it comes to the bathroom window. Of course you want to cover up. But how to still get light into the room? One solution with a growing array of updated options: decorative film that you can use to “frost” your window. These films now come in pebble, rice paper, stained glass, geometric and mosaics (like the pattern shown here bySolyx). Sold by decorativefilms.com. Price varies starting at about $15 a linear foot for 3-foot-wide film. Comes with DIY directions.
