There are a few things to consider when choosing a trowel size for 3×6 Subway Tile. The first is the type of tile you are using.

Finally, consider your own personal preferences. Some people prefer to use a smaller trowel for greater accuracy, while others prefer a larger trowel for greater coverage. Ultimately, the best size trowel for 3×6 subway tile is the one that works best for you and your project.

The Different Sizes of Trowels

When it comes to trowels, there are a few different sizes that you will need to know about in order to properly install 3×6 subway tile. The first measurement that you need to be aware of is the width of the tile. The width of the tile will determine the size of the notches on the trowel. The second measurement is the length of the tile. The length of the tile will determine the size of the space between the tiles, known as the grout joint.

The most common trowel size for 3×6 subway tile is a 1/4″ x 3/8″ trowel. This size is typically used for tiles that are 12″ wide or less. For tiles that are wider than 12″, you will need to use a 1/2″ x 1/2″ trowel. The larger size is necessary in order to accommodate for the wider grout joints.

In addition to knowing about the different sizes of trowels, it is also important to know about the different types of materials that trowels are made from. Trowels can be made from either metal or plastic. Metal trowels are typically used for smaller installations, such as backsplashes, while plastic trowels are better suited for larger projects, such as floors and walls.

The Right Size Trowel for 3×6 Subway Tile

3×6 subway tile is a classic choice for backsplashes, shower walls, and other small tiling projects. The tiles are relatively small and easy to work with, but you’ll need to make sure you have the right size trowel for the job.

The size of your trowel will depend on the adhesive you’re using. If you’re using a water-based adhesive, you’ll need a 1/4″ x 3/16″ notch trowel. If you’re using a thinner, tile mastic adhesive, you’ll need a 1/8″ x 1/16″ notch trowel.

For both types of adhesives, you’ll also need to butter the back of each tile with adhesive before setting it in place. Use a small paintbrush or spreader to apply an even layer of adhesive over the entire back surface of the tile.

Once your tiles are in place, allow the adhesive to dry for at least 24 hours before grouting or continuing with your project.


Now that you know the answer to the question, “What size trowel do you need for 3×6 subway tile?”, you can go ahead and purchase the right size trowel for the job. Be sure to follow the manufacturer’s instructions for installation, and always wear safety glasses when working with tools.
