Follow this guide on how to smooth bathroom walls after removing tile to have a smoother bathroom wall.

Step 1

Apply mastic remover to the wall using a roller at the manufacturer’s suggested thickness. To ensure you have enough material before you begin, measure the wall’s longest and highest points, then multiply these values to determine the square footage. Larger mastic remover containers can cover approximately 100 square feet but verify the manufacturer’s instructions before you begin to ensure you have enough to accomplish the task.

Step 2

Allow the mastic remover to set according to the manufacturer’s instructions before scraping the glue off the wall with a putty knife or metallic scraper. Wipe the entire wall with a moist towel after cleaning it. Reapply the remover to any excess mastic, wait the prescribed time, and remove the adhesive.

Step 3

Sand the walls carefully with a sanding block to eliminate any residues of mastic. Wipe the walls and inspect the surface for any fissures, gaps, or uneven surfaces.

Step 4

Mix a quantity of joint compound in a metal container and apply a thin coat of mixture for every crack or gap with a joint knife. Push the compound into the recessed area with the knife, leveling it along the adjacent wall. Allow this to dry before checking each area to ensure it is flat with the rest of the wall. If not, add a second layer of the compound similarly and allow it to dry. For deeper cracks or holes, use drywall tape over the first application of compound before applying the second coat. This action helps close the hole while reducing the amount of compound needed for the whole finish.

Step 5

If appropriate, rebuild the wall. In certain circumstances, the wall may so deteriorate that patching each location appears pointless. If this is the case, apply between one to three coats of the compound to the whole wall, applying a thin, equal coating with the joint knife while placing it at an angle of 45 degrees and cleaning the knife off any excess compound as you feather the compound out. Work in tiny sections, beginning at the top center and moving down and out till the entire wall is completed. Keep the applications thin; if the compound is applied too thickly, it will never fully set, leaving the wall inconsistent. Allow each coat to cure before putting the next one, then carefully buff every layer before applying the next coat, constantly cleaning the dust from the sanding process with a moist rag. After your last layer, sand it down again for the last time.

Step 6

After sanding each repair, clean the area with a clean towel, and then the process of painting a wall after removing the tile can begin. Apply primer to the entire wall, then finish it as planned.

Pros and cons of smooth bathroom surface wall

For starters, cleaning walls after removing tiles may have necessitated wanting a new bathroom design texture. Before choosing a smooth bathroom panel, let’s explore the pros and cons of smooth bathroom surfaces. Let’s start with the pros.


  • Smooth surface walls provide the bathroom with a smooth, flawless, and modern appearance. They do not show their agedness.
  • Bathroom panels with smooth walls are truly watertight. Water will never erode its surface since they fit flawlessly in a seamless way, preventing even the smallest water droplets from leaking through.
  • There are several smooth surface bathroom wall alternatives. Solid surface showers come in a variety of colors and designs. They can imitate the appearance of natural stone, such as granite. They might have the appearance of ordinary bathroom walls and can also be a solid color. This flexibility enables room for designing the bathroom to suit one’s needs. 
  • Because bespoke solid surface shower surrounds may be made to look like tile or stone, but with no grout, you can appreciate the excellent look without the grout cleaning and upkeep. Smooth surface bathroom walls may provide the style you want without the bother.
  • Smooth surface bathroom walls may be cut and personalized using common tools such as jigsaws, and they can be readily repaired, refinished, and revived if scratched or damaged.


With every aspect that has pros, the cons are usually there, too. Let’s look at the cons of a smooth bathroom surface wall.

  • Smooth bathroom surface panels are pliable, and mobility can occasionally cause cracking, resulting in leaks. Due to the product’s design, you’re leaving yourself exposed to an issue that you do not desire in your bathroom. The majority of the surface boards are of poor quality and should not be used and so one ought to be keen when choosing them. 
  • Bathroom surface panels are an expensive alternative. Although boards are less expensive per board when compared to ordinary tiles, they are not less expensive per inch. The price of acquiring and installing is greater.
  • Boards are quite restricted when it comes to selection choices.   It’s not uncommon to discover only a few selections in your local bathroom store.  You might go through tons of boards and still lack the right design and style that fits your bathroom.
  • Boards are restrictive when it comes to heights. The maximum length in most shower panels is 2.4m, which might cause difficulties with vaulted ceilings. Although a connector in the center is feasible, it can serve as a distraction from the elegant aesthetic that bathroom boards provide.
