How to Tile Around a Window without Trim : Simple Steps

There are a few basic steps that you’ll need to follow to tile around a window without trim:

Step 01: Developing a Work Plan

To tile around a window without trim, you need to develop a work plan. This will help guide you through the entire process and ensure that everything is done correctly.

Step 02: Measuring Your Window

You’ll need to measure your window to determine the correct size for your tiles. Be sure to account for the grout lines when calculating.

Step 03: Cutting the Backer Board

This will be for the bottom row at the window sill, so you’ll have to measure and cut it to fit this area. Be sure that these pieces are precisely cut since they’ll determine how well everything else works together.

Step 04: Remove the Casing and Sill

This will give you access to the studs and install the backer board. You’ll also need to remove the molding and any other obstructions.

Step 05: Insulate the Gap

The wall will be open at this point, so you’ll need to insulate the area with rigid insulation. This will help keep the heat in during the winter and keep the room cooler in the summer.

Step 06: Choose an Edging Option

You can use a few different edging options to finish off the tile work. You’ll have to decide whether or not you want a quarter round, a metal edge, or another type of option that matches your style and design preferences. Some popular edging styles are:

  • Place Bullnose on The Wall: The Bullnose can be used to create smooth edges at the border. It also protects the tile and is resistant to chipping or cracking.
  • Use A Metal Edge: A metal edge is a great option if you’re looking for a sleek and modern look. It’s also very durable and can withstand wear and tear.
  • Using Corner Edging Tiles: It provides a great way to create sharp corners or angles. It’s a popular option for bathrooms or kitchens.
  • Use A Decorative Border: This can be an excellent accent option and help protect the tile’s edge. It’s also a good option if you have pets or small children in your home, as it will prevent them from being injured by sharp edges.

Step 07: Calculating the Size of Tiles

Now that you have all of the measurements, you’ll need to calculate the size of your tiles. This will help you determine how many tiles you’ll need and what size to order.

Step 08: Placing the Tiles in a Pattern

Now that all of your tiles are cut and measured, you can begin tiling. Start at the top by placing tiles around the perimeter of the window, and then fill in the center with whole tiles. Ensure that you leave enough room for grout lines throughout. 

Step 09: Grouting

After everything is placed, you’ll need to clean off the tiles and grout the seams. Allow this to dry for about 24 hours before removing any excess grout.

Step 10: Adding Support

If your window is large and heavy, you’ll need additional support. You can do this by installing a header or brackets that will hold the weight of the window.

Step 11: Coating Joint

Once the window is in place, you can coat the joint with silicone caulk to protect it from moisture and fading.

Once you have followed these steps, you’ll be able to tile around a window without trim in no time. Be sure to take your time and measure everything correctly to fit tightly. Don’t rush the process and try to avoid making mistakes, resulting in wasted materials or a window that doesn’t look right or is hard to open.

Tips for Tiling around the Window

Tips for Tiling around the Window

When tiling around a window without trim, you will need to take some extra steps to make sure your tile job looks professional. Here are a few tips for tiling around the window:

  1. Make sure you use the same type of tile for the entire area around the window. This will create a uniform look.

2. Leave a small gap between the edge of the tile and the edge of the window trim. This will give your tile job a polished look.

3. Use a tile cutter or a sharp knife to cut tiles to size. Be careful when cutting tiles, as they can be intense!

4. If you need to, use thin-set mortar to help hold the edge of the tile in place along the wall.

5. Scrape away excess thin-set during installation with a flat head screwdriver or a trowel. Be careful not to damage your tiles while scraping off excess mortar.

In addition, there are a few questions that can be essential to your understanding of this project. Let’s talk about those crucial questions that might help you.

What Type of Tile Is Appropriate for This Project?

The type of tile you use for this project will depend on the size of the window, the kind of grout you want to use, and the look you are going for. For example, if you’re going to create a traditional look with matching flooring, then white grout is best. Black grout may be a better choice if you want a more modern look. 

When you are looking to tile around a window without trim, it would be best to use ceramic tile. The edge is unnecessary for this project because you want the window frame to show through.

How to Cut the Tile to Fit Around the Window?

How to Cut the Tile to Fit Around the Window

Once you have chosen the correct type of tile, it is time to start cutting it to fit around the window. Measure the size of the window and make a template out of cardboard or paper. Cut the tile to fit the template, then use a sharp blade to score and snap the tiles to work around the window.

What Kind of Sealant Can You Use on Tiles?

There are a variety of sealants that can be used on tiles:

  • You can use an adhered sealant, which is sticky and comes in cartridges, sheets, rolls, or a self-adhered adhesive, which is flexible and comes in hard and soft varieties.
  • Then there’s silicone sealant which you can use to protect your tiles against water and fire. Whichever adhesive you choose, read the instructions carefully and follow them precisely. That way, you’ll get the best possible results.

What Kind of Grout Should be Used?

You could use three types of grout: silicone sealant, mortar, and epoxy.

Silicone Sealant

Silicone sealant is the least expensive option. It is also the quickest to apply. This is because it does not require mixing with water. However, silicone sealant requires at least 12 hours of drying time before you can grout around your window. Also, it will eventually turn yellow over time.


Mortar is the easiest to work with when tiling around a window, but it’s also the most expensive. It provides the smoothest finish compared to silicone sealant or epoxy. But mortar requires at least 30 minutes of drying time before you can grout around your window. And like silicone, it will also eventually turn yellow over time.


Epoxy is tough to work with when tiling around a window and is the most expensive. It provides the smoothest finish compared to silicone sealant or mortar. But epoxy requires at least 24 hours of drying time before you can grout around your window.

In general, silicone sealant is the best option for tiling around a window because it’s the quickest and most affordable. However, if you’re looking for a more polished finish, mortar or epoxy may be a better choice. Just be sure to factor in drying time.

How to Apply the Grout?

How to Apply the Grout

Applying the grout is a relatively simple process. Once the tile is in place, use a grout float to apply the grout. Work in small sections at a time and make sure to get into all of the cracks and crevices. Wipe off any excess grout with a damp cloth, and then allow the grout to dry for 24 hours.

How to Obtain a High-Quality Seal?

To ensure you get a high-quality seal, start with the right product. Ceramic tiles are the best choice for around windows. They are cleanable, scratch-resistant, and have an anti-static surface, which means they won’t be collecting electrical charges from the air.

Consider adding a molding edge to your tile installation to give it a more elegant finish. If you don’t have molding handy, purchase some inexpensive shoe molding at your local hardware store and cut it down to size. You can also ask your tile supplier if they offer any pre-cut pieces of sill trim that would work well in this situation.

What Can You Do to Prevent It from Getting Wet?

One way to prevent the tile from getting wet is to install a water sealant. This will help to keep the water from seeping through the grout and ruining the tile. You can also install trim around the window to help keep the water from hitting the tile directly.

If you already have a trim installed, you can add a water barrier between the edge and the tile. This will help to keep the water from coming in contact with the tile and causing damage.

What is The Purpose of an Edge Bead?

The purpose of an edge bead on window tile is to seal the grout on the top surface of the glass. The sealing properties of this thin strip can protect against water penetration through tile imperfections in most cases.

This only applies to small tiles, not large tiles that are often entirely bordered by a thin layer that perfectly seals off any moisture from entering inside. You’ll also see channels in most corners that fit over these thin pieces to ensure no gaps are missed out during installation.

Precautions While Tiling Around the Window

Precautions While Tiling Around the Window

When tiling around a window without trim, it is essential to take some precautions, such as:

  • Make sure the tiles are completely level and that there is no lippage. This can be done with a spirit level or using spacers to create gaps between the tiles.
  • Ensure that the grout lines are straight by using a straight edge or a guideline.
  • Ensure that the tiles are cut to the correct size and have a consistent grout joint between them. This can be done with a tile cutter or a wet saw.
  • Using adhesive and grout that is suitable for use with tiles. There are many different types of glue and grout on the market. It is recommended that you consult a tile specialist to ascertain which product will work best for your specific situation.
  • Using the correct spacers such as metal, plastic, or colored glass to create uniform grout lines.

The Verdict

It’s not always necessary to use trim when tiling around a window. Tiling around a window without trim can be tricky and require more than one row of tiles. The best way to do it is by using the same pattern for both rows so that you don’t have an obvious line where the wall meets the ceiling or floor.

This article comprehensively discusses how to tile around a window without trim. We hope that these pointers will help make the process easier for you and save time in the future when it comes time to replace another broken or cracked glass pane.
