Leave the kids’ bathroom wall blank if you like cautious rooms. This one wants a bit of softness above the towel rail. The watercolour puppy, soft mint tub and bobbing yellow ducks bring a gentle, playful note that little ones notice straight away. It works beautifully above a changing table, beside a cot, on a nursery gallery wall, or in a family bathroom near the bath. Pair it with pale wood, white painted shelves, woven baskets and cotton textiles in cream, mint or buttery yellow. Don’t crowd it with bold graphic prints or heavy dark frames keep neighbouring pieces light, watercolour-led and child-friendly so the whole wall feels calm and warm.
