Wetwall panels have gained popularity in modern bathrooms across the UK, thanks to their waterproof finish, easy installation, and stylish designs. They offer a practical alternative to tiles, especially in shower enclosures and splash zones. However, as trends evolve and preferences change, many homeowners start to wonder: can you paint over Wetwall panels to update their look without a full remodel?
The short answer is yes, but it comes with specific steps and important limitations. In this guide, we’ll explore when it makes sense to paint Wetwall, how to do it properly, the potential risks, and when it might be better to consider alternatives like replacement or vinyl wraps.
What Is Wetwall and Why Is It Used in Bathrooms?
Before we dive into painting, it’s important to understand what Wetwall is made of. Wetwall panels are often composed of either:
- High Pressure Laminate (HPL): A strong, non-porous surface bonded to a waterproof core.
PVC (Polyvinyl Chloride): Lightweight, waterproof, and highly resistant to mould and mildew.
Wetwall panels are designed to be:
- 100% waterproof
- Grout-free and easy to clean
- Quick to install over existing surfaces
- Stylish, with many finishes including marble, tile, and stone effects
These characteristics make them a favourite in shower cubicles, behind bathtubs, and around sinks.
However, the same features that make Wetwall so water-resistant and low-maintenance—particularly the smooth, sealed finish—also make it difficult for paint to stick.
Can You Paint Over Wetwall Panels?
Technically, yes—you can paint over Wetwall. But there are important considerations to be aware of:
- The surface is non-absorbent, which means paint won’t adhere well unless the panel is prepped properly.
- It’s not recommended in areas of direct water exposure, like the inside of a shower.
- Painted Wetwall will likely require more maintenance and may peel or chip over time.
- You may void the warranty on your Wetwall panels by altering them.
So, while painting is possible, it’s generally considered a temporary or budget-friendly solution, not a substitute for proper wall replacement in high-moisture areas.
When Is Painting Wetwall a Practical Option?
There are scenarios where painting over Wetwall can make sense. You might consider it if:
- You’re renovating a rental property or preparing a home for sale and need a quick visual refresh.
- You want to change the colour scheme without the time or cost of replacing panels.
- The existing Wetwall is in good condition but looks dated or mismatched with new décor.
- The panels are used in less splash-prone areas, such as above a sink or behind a toilet.
If your panels are cracked, peeling, or warped, painting won’t fix the underlying problem. In those cases, replacement is the better option.
Step-by-Step: How to Paint Over Wetwall Panels
If you decide painting is the right approach for your space, you’ll need to follow a careful process to get the best results. Here’s a detailed guide:
1. Clean the Surface Thoroughly
Begin by scrubbing the Wetwall panels using a mild detergent or a mixture of vinegar and warm water. Remove any soap scum, mould, grease, or mildew. Rinse with clean water and dry the surface completely.
Tip: Avoid using abrasive cleaners or scouring pads, as these can damage the surface.
2. Lightly Sand the Surface
To help paint adhere to the glossy surface, you’ll need to create a slightly rough texture. Use fine-grit sandpaper (around 180–220 grit) to gently scuff the surface in circular motions. Wipe away dust with a tack cloth.
Caution: Do not over-sand. You just want to break the sheen, not dig into the material.
3. Apply an Adhesion Primer
This is a critical step. Choose a bonding primer specifically formulated for use on plastic, laminate, or tile surfaces. Apply an even coat with a brush or roller and let it dry thoroughly according to the manufacturer’s instructions.
Some recommended UK products include:
- Zinsser Bulls Eye 1-2-3
- Dulux Difficult Surfaces Primer
- Ronseal One Coat Super Primer
4. Choose a Water-Resistant Paint
Pick a paint that can handle moisture and temperature changes. Options include:
- Acrylic latex paint for general bathroom use
- Epoxy-based paint for durability and water resistance
- Bathroom-specific emulsion with mould-resistant properties
Apply the first coat using a high-density foam roller or brush. Allow to dry fully before applying a second coat.
5. Add a Waterproof Sealant (Optional)
For extra protection, especially in humid environments, consider finishing the painted Wetwall with a clear polyurethane or bathroom-grade sealant. This helps prevent moisture damage and prolongs the paint’s life.
Common Mistakes to Avoid
Painting Wetwall isn’t foolproof. Avoid these mistakes for better results:
- Skipping surface prep: Paint won’t bond properly without sanding and priming.
- Using the wrong paint: Standard wall paint won’t hold up in damp conditions.
- Painting inside showers: Even the best paint won’t last in constant contact with water.
- Rushing drying times: Each layer needs to cure fully before the next is applied.
Pros and Cons of Painting Wetwall
Let’s weigh up the advantages and drawbacks:
Pros:
- Low-cost alternative to panel replacement
- Quick cosmetic refresh
- Can match new bathroom themes or colour schemes
Cons:
- Less durable than original Wetwall finish
- Not ideal for wet zones
- Paint may eventually peel or bubble
- Requires detailed prep and ongoing maintenance
Alternatives to Painting Over Wetwall

1. Full Panel Replacement

3. Decorative Enhancements
Add modern fixtures, floating shelves, mirrored cabinets, or decorative lighting to shift the focus away from the existing wall panels.
FAQs: Painting Over Wetwall
Can you paint Wetwall in a shower enclosure?
No. Even with primer and waterproof paint, moisture exposure in a shower will eventually cause peeling.
How long will painted Wetwall last?
With proper prep, it may last 1–3 years in low-moisture zones. In humid areas, the finish can degrade much faster.
Will painting Wetwall void my warranty?
Yes, most manufacturers will consider painted panels as altered and no longer eligible for warranty support.
What’s the best paint to use on Wetwall?
A high-quality acrylic latex or epoxy-based bathroom paint with mould resistance is best. Always pair it with a suitable primer.
Final Thoughts
If you’re looking for a short-term solution or a budget-friendly way to freshen up your bathroom, painting Wetwall can work—but only with the right prep and expectations. It’s not ideal for every situation, especially areas with heavy water exposure.
If your goal is long-term quality, replacing your Wetwall panels with a new design is the better investment.
