Schluter Kerdi-Board Thickness: Finding the Right Fit for Your Curbless Shower
Choosing the right shower pan system can be a daunting task, especially when dealing with curbless showers. Schluter Systems offers a variety of solutions, and one of the most popular is the Kerdi-Board, a waterproof backer board that's specifically designed for shower floors.
But a question that often arises is "how thick should my Kerdi-Board be?" The answer depends on several factors, including the size of your shower, the type of tile you're using, and the overall design.
Understanding Kerdi-Board Thicknesses
Schluter Kerdi-Board comes in three thicknesses:
- 3/8 inch (9.5mm): This is the thinnest option and ideal for smaller showers or when space is a concern. It's also a good choice for showers where a low profile is desired.
- 1/2 inch (12.7mm): This is the most common thickness and offers a good balance of strength and flexibility. It's suitable for most shower sizes and tile types.
- 5/8 inch (15.9mm): This thickness is recommended for larger showers or showers with heavier tile installations. It provides extra strength and support, particularly for larger format tiles.
Factors to Consider when Choosing Thickness
Here are some key points to consider when determining the right Kerdi-Board thickness:
- Shower Size: Smaller showers typically require thinner Kerdi-Board, while larger showers benefit from the extra support of thicker options.
- Tile Type: Heavier or larger format tiles require thicker Kerdi-Board for adequate support.
- Floor Joist Spacing: If your floor joists are spaced further apart, you may need a thicker Kerdi-Board to ensure stability.
- Slope: A proper slope is crucial for a curbless shower, and the chosen Kerdi-Board thickness will influence the slope achieved.
- Installation Method: Different installation methods may require varying thicknesses.
