When it comes to bathroom renovations, one of the biggest concerns is time and disruption. Many homeowners are looking for quick, hassle-free solutions to update their bathroom without a full rip-out. This raises an important question: Can you put shower panels over existing panels?
The short answer is yes—but it depends on the condition of your current panels and the materials used. In this blog, we’ll guide you through everything you need to know about fitting new shower panels over existing ones, the pros and cons, how to do it properly, and when it might be better to start fresh.
What Are Shower Panels?
Shower panels, also known as Wetwall panels or bathroom wall panels, are large waterproof boards designed to protect walls from moisture and enhance the look of your bathroom.
They are commonly made from:
- PVC (Polyvinyl Chloride): Lightweight, waterproof, and easy to install
- Acrylic: Sleek and glossy, often used for a modern aesthetic
- HPL (High-Pressure Laminate): Tough and highly durable, bonded to a waterproof core
- Solid core materials (like MDF or composite board): Sturdy and heavier-duty
At Annick Bathrooms, we offer a wide range of these panels, suited for every bathroom style and budget.
Can You Fit New Shower Panels Over Old Ones?
Yes, in most cases, you can fit new shower panels over existing ones—as long as the surface underneath is:
- Flat and smooth
- Dry and free of mould
- Securely attached to the wall (no loose or damaged sections)
This method is often used in quick bathroom refurbishments where removing the original panels would be too labour-intensive, messy, or costly.
However, not all panels are suitable for over-panelling. For example, textured tiles or warped PVC panels can cause problems with adhesion or alignment. We’ll explain more below.
Benefits of Installing Panels Over Existing Panels
This technique can be incredibly efficient if done right. Here’s why:
Saves Time and Effort
Removing existing panels can be time-consuming and may require additional repair work. Over-panelling skips that step.
Reduces Mess and Disruption
No need to strip the walls, dispose of debris, or deal with old adhesive.
Cost-Effective
Fewer labour hours and less waste mean a more affordable upgrade.
Extra Insulation and Soundproofing
Layering new panels over old ones can slightly improve insulation and sound resistance.
Keeps Your Bathroom Functional
Since the renovation is less invasive, your bathroom remains usable during the process.
When Is It Not Recommended?
Despite the convenience, over-panelling isn’t always the best solution. You should avoid it if:
- The original panels are cracked, swollen, or mouldy
- The surface is uneven, bowed, or loose
- The old adhesive is failing or panels have begun detaching
- There is significant water damage or structural concerns underneath
In these cases, installing new panels directly over the old ones may trap moisture and lead to hidden mould, rot, or poor adhesion. Removing the old panels is the safer choice.
Step-by-Step: How to Install New Shower Panels Over Existing Ones
If your current panels are in good condition, here’s how to properly fit new ones on top:
1. Assess the Surface
Check that your existing panels are:
- Securely bonded to the wall
- Clean and free from grease or soap build-up
- Free of bulges or damage
If you spot any damp or black mould behind or around joints, stop here and remove the panels instead.
2. Clean Thoroughly
Use a non-abrasive cleaner to remove dirt, soap, and grime from the existing panels. Rinse well and let the surface dry completely.
3. Mark and Measure
Measure the area precisely and plan your panel layout to avoid awkward joins or cuts.
Tip: Cut panels to size before applying adhesive, especially if using a mitre saw for thicker boards.
4. Use the Right Adhesive
Apply a high-grab waterproof adhesive, such as:
- Wetwall Hi-Tack Adhesive
- UniBond No More Nails Waterproof
- Multipanel Adhesive for Wall Panels
Apply in vertical lines or beads across the back of the panel.
5. Apply the New Panel
Carefully press the new panel onto the existing one. Use a spirit level to ensure it’s straight, and apply firm pressure across the surface to secure it.
Use temporary supports if needed until the adhesive sets.
6. Seal the Edges
Finish with a high-quality waterproof sealant (like silicone) at all joints and corners to prevent water ingress.
Panel Over Panel: What to Watch Out For
While fitting new panels over old ones is possible, here are a few extra things to keep in mind:
- Thickness Increase: Double layers can create awkward bulk, especially around fittings, trim, or windows.
- Trimming Fixtures: Wall-mounted accessories or shower fittings may need to be adjusted.
- Weight Consideration: Adding heavy panels on top of heavy core panels may require extra mechanical fixings (like screws or battens).
- Seal Integrity: Pay close attention to corners and joints—these are the first places where leaks start if sealant fails.
Frequently Asked Questions
Do I need to remove the original trim or corner profiles?
Yes, trims and corner profiles should be removed and replaced with new ones to suit the thickness of the new panels.
Can I do this in a shower enclosure?
Yes, as long as you thoroughly seal all joints and the base is watertight. Any imperfections underneath can lead to leaks later.
Will putting panels over panels cause damp?
Not if the existing panels are dry and in good condition. Always check for signs of damp or mould before proceeding.
Can I fit acrylic panels over PVC panels?
Yes, but make sure the surface is flat, and use the correct adhesive for both materials.
Alternative Solutions to Consider
If you’re not sure about over-panelling, here are some alternatives that may better suit your bathroom goals:
1. Full Panel Removal and Replacement
This is the most secure and long-lasting method. You’ll get a clean finish and peace of mind knowing there are no hidden issues behind the walls.
2. Tile Over Panels (Not Recommended)
Some people ask about tiling over panels. In most cases, this is not advised. Tiles need a solid, stable surface like cement board or plaster—not flexible PVC or acrylic.
3. Panel Resurfacing
For some panel materials, you might be able to resurface them with vinyl wraps or specialist coatings. This is less durable but a quick cosmetic fix.
Final Verdict: Is It a Good Idea?
If your current panels are solid, flat, and free of damage, then installing new shower panels over the top is a viable option. It’s ideal for quick upgrades, property rentals, or avoiding mess during a renovation.
However, this method relies on the quality of the existing installation. If there’s any doubt, especially regarding moisture or structural stability, it’s always safer to strip and start fresh.
