- 3What happens behind the panelling if there's a leak?
- 4How long should this panelling last in a bathroom?

💡Myth vs Reality
Common Myth
"Wall panelling is a budget alternative to tiles"
The Reality
Quality waterproof panelling with proper installation can cost as much as mid-range tiles. Cheap panelling often fails within a few years.
Common Myth
"You can use panelling anywhere in a bathroom"
The Reality
MDF and non-waterproof panels should never be used in wet zones. Even 'moisture-resistant' MDF will fail if regularly splashed.
Common Myth
"Panelling is easier to install than tiles"
The Reality
Proper installation requires careful preparation, accurate cutting, and professional sealing. DIY mistakes lead to moisture damage.
What to look for
- •100% waterproof PVC panels for shower areas
- •Tongue-and-groove joints that seal properly
- •Quality trims and corner pieces for neat finishing
- •Panels thick enough to resist flexing (at least 8mm)
Common mistakes
- •Using MDF panelling in shower areas where it will eventually fail
- •Not sealing panel joints properly, allowing moisture behind
- •Installing over damp or uneven walls
- •Forgetting to leave expansion gaps at edges
