Regular plaster drywall is the most ordinary choice for bathroom walls, but a variation, greenwall, is a better choice. It is inexpensive, easy to install, and has a water-resistant facing that makes it less resistant to mold and stains. The type of paint you choose to cover the greenwall will be the most important choice you make in using this type of material in a bathroom. Select a semi-gloss or high-gloss paint. These paints will allow the walls to be wiped clean with a damp cloth. Avoid matte paints, which cannot be easily cleaned.
Ceramic tile is one of the most costly materials to install, as it requires precision to keep the tiles orderly, but it is also impervious to water and mold, making it ideal for bathroom walls. It can be wiped clean with a cloth and is especially appropriate for bathroom decor. Although tile can be installed to the ceiling, consider covering just half of the wall and applying a semi-gloss paint over the remainder of the wall if installation time and cost are a concern.
Cement backer board
Cement backer board serves the same purpose as traditional drywall, but it can be expected to last for the lifetime of the house. They are not affected by any amounts of water, such as plumbing leaks, which make them ideal for usage in bathrooms. The boards should be covered with a water-resistant covering, such as polyethylene plastic or vinyl wall coverings.
