There are multiple techniques you can employ to decorate a bathroom wall. Often, homeowners experiment with new painting techniques on their bathroom walls before applying the technique on other walls in the house. This is because a bathroom is small enough that they can easily correct any mistakes, such as bad color choices.
Sponge Painting

Stenciling
There are plenty of stencils available from craft and home improvement stores. Choices range from scroll designs to animals, flowers, letters and anything in between. Make your own stencil if you cannot find a ready-made design you like. With stenciling, you do not have to worry about not being "artistic" enough because all you have to do is apply paint using a stenciling brush or sponge on the stencils.
Attach the stencils to the wall with blue painter's tape to keep them in place while stenciling. Make sure to wipe off excess paint from your sponge or stencil brush so that the paint will not smear underneath the stencil, which can ruin the image. Use a combination of stippling and circular motion instead of up-and-down motion to avoid smearing. Apply different shades by layering colors to add dimensions to your design. Avoid mistakes by practicing the stenciling technique on a cardboard.
Murals
Create murals to decorate your bathroom walls. Draw your scenery freehand or use layers of stencils and combine with freehand styles to make it easier to complete a mural with different images. Use a projector to copy images onto the walls to minimize mistakes. To make murals more interesting, apply them on all four sides of your walls as well as the ceilings.
