Tile Backer Boards
Tile backer boards provide a strong, moisture-resistant base for tiling in bathrooms, wet rooms and floors. Designed to prevent movement, cracking and water damage, they are the ideal alternative to plasterboard for long-lasting tiled installations.
Waterproof Boards for Bathrooms, Wet Rooms & Floors
Tile backer boards provide a strong, moisture-resistant foundation for tiling in bathrooms, wet rooms, kitchens and floors. Designed to outperform plasterboard and plywood, they create a rigid surface that prevents tile movement, cracking and water damage.
Whether you’re a professional installer or carrying out a home renovation, tile backer boards offer a reliable base for long-lasting tiled finishes.
What Are Tile Backer Boards?
Tile backer boards are specialist construction boards used as a substrate before tiling. Made from cement or reinforced core materials, they are designed to withstand moisture and provide a rigid, stable surface for tiles.
Unlike plasterboard or plywood, tile backer boards do not deteriorate when exposed to water, making them essential for areas such as bathrooms, wet rooms and kitchens.
They are widely used by both professional installers and DIY customers to ensure a high-quality, long-lasting tiled finish.
Where Are Tile Backer Boards Used?
Tile backer boards are suitable for a wide range of applications:
Bathrooms
Used behind showers, baths and basins to create a waterproof base ready for tiling.
Wet Rooms
When combined with tanking systems and wet room kits, tile backer boards help form a fully waterproof environment.
Floors
Installed on floors to improve rigidity and provide a reliable base for tiles.
Underfloor Heating
Commonly used with electric underfloor heating systems to support heat distribution and structural stability.
Tile Backer Boards vs Plasterboard
Choosing the right substrate is essential for long-term performance.
Tile backer boards offer several advantages over plasterboard:
- Moisture resistant – designed for wet environments
- Stronger and more rigid – reduces tile movement
- Long-lasting – will not break down when exposed to water
- Suitable for floors and walls
Plasterboard, while suitable for dry areas, can absorb moisture and weaken over time, making it less suitable for bathrooms and wet rooms.
Choosing the Right Tile Backer Board Thickness
Selecting the correct thickness is important for achieving a stable tiled surface:
- 6mm tile backer boards
Ideal for wall applications and overlaying existing solid surfaces - 10–12mm boards
Recommended for floors and areas requiring additional strength - 20mm boards and above
Suitable where insulation or build-up is required
Choosing the right board helps prevent movement and ensures a professional finish.
Waterproof Tile Backer Boards
Waterproof tile backer boards are specifically designed for use in high-moisture environments such as bathrooms and wet rooms.
They provide a reliable barrier against water penetration when installed correctly and combined with tanking systems. This makes them ideal for shower enclosures, wet room floors and any tiled area exposed to regular moisture.
