If you really want to mix things up in the DIY stakes, an ‘accent ceiling’ is a daring but cheap way to transform a room. Painting a feature wall can be a total game-changer, but the bathroom is often overlooked in this regard despite deserving more attention. Depending on your existing interior, a dark ceiling (like the one pictured) can look chic, clean and crisp, but it is an experimental choice. If you’re not quite willing to take a leap that big, opt for a warmer blue. Robert Dyas will be a good place to start to identify the perfect colour.
