When it comes to choosing the right tile underlayment for your bathroom remodel, you have two major options: Kerdi board and cement board. Both of these materials serve as tile substrates and can be used for underlayment in various applications.
While they have similar purposes, there are some key differences between them. Kerdi board is made of extruded polystyrene foam and features special reinforcement material and fleece webbing for effective anchoring. It is lightweight, easy to work with, and waterproof, making it a popular choice for bathrooms and kitchens.
On the other hand, cement board is made of cement with a mesh lining and is known for its affordability. It is slightly more durable than Kerdi board and offers fire resistance. However, it is heavier and not as waterproof as Kerdi board.
Both materials come in different sizes and can be used for tile underlayment in floors, walls, bathrooms, and kitchens. The cost of Kerdi board is about twice as much as cement board. Overall, the choice between Kerdi board and cement board depends on factors such as the level of moisture exposure, durability requirements, and installation ease.
Key Takeaways:
- Kerdi board and cement board are two popular options for tile underlayment in bathroom remodels.
- Kerdi board is lightweight, easy to work with, and waterproof, making it ideal for wet areas like bathrooms and kitchens.
- Cement board is more affordable, slightly more durable, and offers fire resistance.
- Consider factors such as moisture exposure, durability requirements, and ease of installation when choosing between the two materials.
- Both materials come in different sizes and can be used for tile underlayment in floors, walls, bathrooms, and kitchens.
Key Factors to Consider when Choosing Between Kerdi Board and Cement Board
When deciding between Kerdi board and cement board for your tile underlayment needs, there are several key factors to consider that will help you make an informed decision.
Waterproofing
Both Kerdi board and cement board can be used in wet areas, but Kerdi board has a higher level of waterproofing due to its composition. Its extruded polystyrene foam construction makes it resistant to water penetration, making it an ideal choice for bathrooms and kitchens.
Weight
Kerdi board is lightweight, which makes it easier to handle, transport, and install. On the other hand, cement board is heavier and may require assistance during installation, particularly for larger tiles or vertical applications.
Ease of Cutting
Kerdi board is easier to cut than cement board. It comes with pre-drawn measurement lines, allowing for precise cutting without the need for additional tools. Cement board, however, can be more challenging to cut and may produce more dust during the process.
Ease of Installation
Thanks to its lightweight nature and ease of cutting, Kerdi board is generally easier to install compared to cement board. The pre-drawn measurement lines on Kerdi board also contribute to a smoother installation process.
Fire Resistance
Cement board offers better fire resistance compared to Kerdi board. It is a suitable choice for applications where fire resistance is a priority, such as fire-rated walls.
Durability
While both materials are durable, cement board tends to be slightly more robust and can better withstand heavy impacts. However, it’s important to note that both materials can potentially crack under extreme pressure.
Cost
Cement board is generally more affordable than Kerdi board, making it a cost-effective option for projects with budget constraints.
Composition
The composition of the two materials is different. Kerdi board is made of extruded polystyrene foam with special reinforcement material and fleece webbing, while cement board is made of cement with a mesh lining.
Considering these key factors, it is crucial to evaluate your specific project requirements, such as the level of waterproofing needed, weight limitations, ease of cutting and installation, fire resistance, durability expectations, budget constraints, and the specific composition that aligns with your project goals. By carefully considering these factors, you can confidently select the right material between Kerdi board and cement board for your tile underlayment needs.

Conclusion
In conclusion, the decision between Kerdi board and cement board for your bathroom remodel should be based on careful consideration of the pros and cons of each material. Kerdi board offers several advantages, including its lightweight nature, ease of installation, and superior waterproofing. This makes it an excellent choice for wet areas like bathrooms and kitchens where moisture resistance is crucial. However, it’s important to note that Kerdi board is slightly more expensive than cement board.
On the other hand, cement board is a more affordable option that provides better fire resistance. It is a durable material, albeit not as waterproof as Kerdi board. Both Kerdi board and cement board can be used for tile underlayment and are available in various sizes to accommodate different spatial requirements. When making your decision, it’s essential to consider factors such as the level of moisture exposure, durability needs, ease of installation, and budget constraints.
To make the best choice for your bathroom remodel, carefully assess your project requirements and prioritize the qualities that matter most to you. Whether you prioritize lightweight construction, easy installation, superior waterproofing, fire resistance, or affordability, evaluating these factors will help you make an informed decision that suits your needs. Choose the material that best aligns with your project goals and enjoy a successful and satisfying bathroom remodel.
