Can You Install Wall Panels Over Existing Tiles?

There is a moment when your wall panels in your bathroom or kitchen need to be replaced. Maybe because it looks old or it doesn't match your current personality anymore. But you know one thing: they should be gone ASAP.

However, the second you imagine how the renovation could look: exhausting, dirty, unusable, and expensive if you bring professionals, you'll scratch the idea.

Then, you probably come here because you want a shortcut to replace the look simply by covering the existing tiles with wall panels. Can you really do that?

The short answer is yes.

In most cases, you can install wall panels directly over your existing tiles. This way, you can skip the complicated procedure such as demolition and retiling, entirely.

The longer answer, however, depends on the various factors such as the type of panels, the condition of the original wall, installation techniques, and general planning. Without proper planning and execution, you may want to redo the job every year.

This guide will help you determine whether this procedure is worth trying and prepare the tools and techniques you should have to do the job properly.

Installing wall panels are best for three main reasons:

First, you have physical limitations such as you're renting the space, so you don't have any right to demolish the ugly wall. Second, you have time and energy as an enthusiastic DIYer to cover the old tiles yourself. Third, you have a tight budget but you want a fresh-looking wall.

Covering existing tiles with wall panels really sounds like putting a Band-Aid, and it is. It doesn't solve the main issue you're having permanently. If you care about longevity, and you're going to live there for a long time, it is better to have your wall remodeled properly with new tiles instead. If the problem is the grout line, you can find wider tiles instead to minimize the effect.

Wall paneling can go over tile in bathrooms, kitchens, bars, wall accents, and anywhere else you've got an existing tiled surface. However, not all surfaces are the same.

Here are the basic requirements before you start:

• The base tiles are sticking to the wall properly with no loose or hollow-sounding sections when you knock them.
• The surface is clean, dry, and free of any residue. It is recommended to use acetone or lacquer thinner, and make sure to avoid any petroleum-based cleaners, especially if you use a water-based primer.
• The tiles are flat, and this is more important if you have longer or wider wall panelling. Remove any protruding items, such as soap holders and nails.
• If you want to extend the wall panels beyond the initial wall tiles, prepare the surface to match the height of the current tiles. You can use wood panels to do this.
• Make sure to seal the edges and joints to prevent moisture and water from seeping between the tiles and panels. They can reduce the durability of the wall panels.

Those bare minimum requirements are non-negotiable. Unfortunately, it is not worth continuing the project if your tiles aren't ready. You'll end up disappointed or spending time, money, and energy redoing the work.

Survey data from UK bathroom fitters show an approximate 78% success rate of installing wall panelling over existing tile. Meanwhile, the rest failed because of a lack of surface preparation.

WPC panels: Wood-plastic composite is highly recommended for anyone wanting a natural wood look without the real-wood level maintenance. However, it's chosen more for the looks than its performance. As it still contains organic material (the wood), it is not good to be used in wet areas such as the bathroom.

Test your wall and run this checklist:

• Tap test – Tap each tile lightly with your hands or any object and listen. Compare it with adjacent tiles to know the difference. A hollow sound means it's no longer glued to the wall properly, and it needs to be retiled before anything goes over it. The more you have hollow sounds, the less viable your wall panel project becomes.
• Crack check – Any cracked or chipped tiles should be repaired and you can do it by scraping out loose tiles with a screwdriver and replacing them with epoxy tile fillers. Make sure to sand it down to ensure a smooth surface.
• Flatness test – Hold a level against the wall in a few spots, both horizontally and vertically to ensure its flatness.
• Moisture check – Look for staining, soft spots, or discoloration, especially near the shower, plumbing fixtures, or underneath the shower. If you find the grout line sweating, it is better to fix the issue first which is usually through demolition.
• Grout condition – Wide panels will hide the grout line, and that's why you should ensure its condition is still good.

It is not recommended to move forward with the project if the surface is not ideal. Things like multiple hollow tiles, water infiltration, uneven surface, and peeling tiles require retiling instead of placing over new panels. Otherwise, you're compromising the end result.
