There's a reason why blue tops most people's favorite color list. It evokes a calm, soothing vibe, reminiscent of clear skies, endless oceans and crystal-clear waters, which is probably why we often turn to blue for our bathroom designs. Whether we opt for azure, teal, aqua, cobalt, sapphire, indigo or cerulean, blues are the restful hue we need to turn our bathrooms into the ultimate retreats.

Double up on your blues in two opposing shades to create chic contrast. Sky blue walls pair with dark blue-glazed ceramic tiles in the HGTV Dream Home 2020 guest bathroom, which is finished off with a crisp white vanity and brushed nickel fixtures.

Stay with the classics — they get that moniker for a reason — but don't be afraid to look at them with new eyes. For this bathroom, designer Morgan Galbraith grounds the space in truly traditional penny-round tile but opts for a pretty blue rather than the typical shades of black and white.

Turn to wallpaper to bring color and pattern into your space. Whether you choose traditional pre-pasted or removable peel-and-stick, wallpaper instantly transforms blank walls. A Greek key pattern in shades of blue takes an otherwise simple white bathroom to a whole new level of style.
