What Size Trowel for 3x6 Subway Tile in Shower?
When installing 3x6 subway tile in a shower, the right trowel size is crucial for achieving a strong and even bond. Choosing the wrong trowel can lead to uneven tile installation, weak adhesion, and even cracked tiles. Here's a breakdown of trowel sizes and their suitability for 3x6 subway tile:
Understanding Trowel Notches
Trowels are designed with different notch sizes, each suited for a specific tile size and application. The notch size determines the amount of mortar that is spread and, consequently, the bond strength.
- Small Notches (1/8" or 1/4"): These are typically used for smaller tiles like mosaics or thin tiles. They offer a thinner mortar bed and are less suitable for 3x6 subway tiles.
- Medium Notches (3/16" or 1/4"): These are a good starting point for 3x6 subway tiles, providing a balance between adequate coverage and manageable mortar application.
- Large Notches (3/8" or 1/2"): These are typically used for large format tiles and require a thicker mortar bed. They are generally not recommended for 3x6 subway tiles unless the shower floor is uneven.
Choosing the Right Size for 3x6 Subway Tile
For 3x6 subway tile in a shower, a 3/16" or 1/4" notch trowel is the most common and recommended size.
- 3/16" notch: This offers a good balance between coverage and manageability. It provides sufficient mortar for a strong bond, while still being easy to spread evenly.
- 1/4" notch: This is a slightly larger notch and is ideal if your shower walls are slightly uneven or if you want extra bond strength.
Factors to Consider
Besides the tile size, here are some other factors to consider:
- Mortar Type: Different mortar types have varying consistency. If using a thin-set mortar, a smaller notch size might be appropriate. However, if using a standard mortar mix, a larger notch size may be required for adequate coverage.
- Shower Wall Condition: If your shower walls are uneven, you might need a slightly larger notch size to fill the gaps and ensure a consistent bond.
- Personal Preference: Some installers prefer a larger notch size for greater coverage, while others prefer a smaller notch for easier spreading.
Conclusion
Ultimately, the best trowel size for your 3x6 subway tile shower will depend on the specific factors mentioned above. Start with a 3/16" or 1/4" notch trowel and adjust based on your needs and the specific mortar you are using. If you are unsure, consult with a professional tile installer for guidance.
