What Size Trowel for Subway Tile Shower?
When tiling a shower with subway tile, choosing the right trowel size is crucial for achieving a beautiful and durable finish. The trowel size directly impacts the amount of mortar used, which affects the tile's adhesion and the overall look of your shower.
Understanding Trowel Size and Mortar Coverage
Trowel sizes are typically measured by the width of the notched side, with common sizes ranging from 1/4" to 1/2". The notches on the trowel help create even mortar beds that provide proper support for the tiles.
- Smaller trowel sizes (1/4" - 3/16"): These are suitable for smaller tiles and thinset mortar. They create a thin mortar bed, which is ideal for creating a smooth, flush surface.
- Larger trowel sizes (1/2" - 3/8"): These are better suited for larger tiles and thicker, modified thinset mortar. They create a thicker mortar bed, providing more support and better adhesion for larger tiles.
Choosing the Right Trowel Size for Subway Tile
For a subway tile shower, a 1/4" or 3/16" trowel is typically the best choice. This size strikes a balance between providing adequate support for the tiles and maintaining a smooth, even surface.
Here's a breakdown of why a 1/4" trowel is often preferred:
- Improved Appearance: A thinner mortar bed helps minimize the chances of mortar showing through the grout lines. This results in a cleaner and more polished look.
- Easier Grouting: With a thinner mortar bed, grouting becomes easier and less messy.
- Cost-Effective: Using a smaller trowel requires less mortar, saving you money.
When to Consider a Larger Trowel
In some cases, a larger trowel might be necessary:
- Large Subway Tile: If you're using larger subway tiles, consider a 3/16" trowel for better support.
- Uneven Wall Surface: For walls with significant imperfections, a larger trowel can help compensate for the unevenness and ensure proper tile adhesion.
Always consult with the tile manufacturer's recommendations and the thinset mortar's instructions for specific trowel size suggestions.
Conclusion
Selecting the right trowel size is an essential step in achieving a successful subway tile shower. A 1/4" trowel is usually ideal for most subway tile installations, but consider the factors mentioned above to make the best decision for your project. Remember to always choose a trowel size that provides adequate support for your tiles while maintaining a smooth and aesthetically pleasing surface.
