What’s the bathroom missing? Dark green with some nerve. One small picture is all it takes to turn a functional room into somewhere a child actually wants to be, and the cream background keeps it light rather than loud. Hang it at child eye-level beside the bath, above a towel rail, or on the narrow bit of wall by the door. It sits happily in a nursery or kids’ bedroom too. Pair it with pale wood, white panelling, soft towels and woven baskets. Don’t crowd it with busy patterned tiles or bright plastic storage in clashing colours this one needs a little quiet space around it to land the joke. As a canvas, the frameless edge keeps it relaxed and easy in a family room.
