A guest bathroom is a secondary full bath that you open to visitors and overnight guests. A guest bathroom should be a welcoming, relaxing space for your guests, but above all it should be user-friendly. If you want to remodel your guest bathroom, for a new inspiration take some guest bathroom ideas decor. Guest bathroom ideas decor can be as simple as adding a few accessories and color schemes. For example, if skydiving is your favorite pastime, paint the ceiling in your guest bath a sky blue and add your own cloud formations to enhance the look. Then, display personal skydiving photos on the walls and use a pseudo-parachute shower curtain. Accessorize the room with white and sky blue towels, area rugs and plane-related novelty cups and containers.
