Tiling Around Shower Window: Step-by-step Guide and Tips

If you have a shower window, there are a few things you need to do to make sure it is properly sealed and waterproof.

One way to do this is to tile around the shower window. Tiling will provide a water-resistant barrier that will help keep your shower area dry and prevent mold and mildew from forming. You will need to install a backer board, place the tiles using adhesive, and then apply caulk and grout.

However, tiling around a shower window can be tricky, even for the seasoned. Let’s take a look at the process in detail.

What You Will Need

Before you begin work, make sure you have all the tools and materials you will need.

You will need the following items:

  • Tiles (in the size, shape, and color of your choice)
  • Thin-set mortar/tile adhesive
  • Tile Spacers
  • Grout
  • Sponge
  • Bucket
  • Trowel
  • Caulk gun
  • Caulking
  • Putty knife
  • Drill
  • Glass drill bit
  • Tile cutter
  • Wet saw (optional)
  • Rubber gloves
  • Safety goggles

Tiling Around Shower Window: Step by Step

Here are the steps on how to tile around a shower window safely and efficiently:


Start by measuring the area around the shower window. This action will help you determine how many tiles you need to purchase.

Apart from the usual tile trim, you will also need to purchase caulk and grout.

Plan the Layout

Once you have all of your materials, you need to plan your tile layout. First, decide where you want the tile to start and end.

If you are working with a large shower window, you may want to consider starting in the middle and working your way out. This will help ensure that the tile is evenly spaced and looks symmetrical.

If you work with a smaller shower window, you may want to start at one end and work your way across.

Whatever method you choose, be sure to plan the layout before you start tiling.

Cut the Tile

Once you have planned the layout, it is time to cut the tile.

You must measure and mark each cut’s tile when working with a large shower window.

You can use a wet saw to make the cuts if you work with a smaller shower window.

Be sure to wear safety goggles and a dust mask when cutting tile.

Do a Dry Fit

Before you apply the thinset mortar or tile adhesive, it is a good idea to do a dry fit. This means you lay out the tile in the planned pattern without attaching it to the wall.

This will help you get an idea of how the tile will look and also let you make any necessary adjustments.

Once the tile is laid out, take a step back and look at it from a distance and if you see any areas that need to be adjusted.

Install the Backer Board

When working with a large shower window, you must install a backer board before tiling. This step will provide additional support for the tile and help prevent it from cracking.

To install the backer board, screw it into the studs around the shower window.

Wear gloves and a dust mask when working with the backer board.

Angle the Window Sill Appropriately

The next step is to angle the window sill so it slopes toward the shower. In this way, you will prevent water from pooling on the sill.

Use a putty knife to remove any old caulking from the sill. Then, use a caulk gun to apply a bead of caulking around the edge of the sill.

Next, use a putty knife to smooth the caulking and create a sloped edge.


Once the sill is angled correctly, you must apply a waterproofing sealant. This will help prevent water from seeping behind the tile and causing problems.

Use a caulk gun to apply a bead of waterproofing sealant around the perimeter of the shower window.

Use waterproofing membrane tape to seal any seams or cracks.

Be sure to follow the manufacturer’s instructions when applying the waterproofing sealant.

Apply the Tile Adhesive

After cutting the tiles, it is time to apply the tile adhesive.

Start by applying a thin layer of adhesive to the back of each tile. Be sure to spread the adhesive evenly.

Place the Tiles

Once the adhesive is applied, you can begin placing the tiles around the shower window.

Start at the bottom and work your way up, placing each tile into the adhesive.

Use a level to ensure that the tiles are even as you go.

If you work with a smaller shower window, you may need to cut some tiles to fit.

Be sure to use a wet saw to make any cuts.

Cure the Tile Adhesive

Before moving to the next step, you must allow the tile adhesive to cure. It usually takes 24 hours.

Once the adhesive is cured, you can move to the next step.

Remove Tile Spacers

After the adhesive has cured, you need to remove the tile spacers.

Use a putty knife or screwdriver to pry the spacers out of the adhesive.

Once all of the spacers are removed, you can move to the next step.

Remove Tile Spacers

Apply the Caulk

After the tile is in place, you must apply caulk around the edges.

Start by running a bead of caulk along the outside edge of the tile.

Then, use your finger to smooth out the caulk.

Repeat this process around all of the edges of the shower window.

Apply the Grout

Once the caulk is dry, it is time to apply the grout.

Start by mixing the grout according to the manufacturer’s instructions.

Then, apply the grout to the joints between the tiles.

Finally, use a wet sponge to wipe away any excess grout.

Allow the grout to dry for 24 hours before using the shower.

Pro Tip

During thin-set application, some can get in the shower drain. To avoid this, put a wet rag over the drain. This will keep the thin-set from getting in, and you can toss the rag when you’re done.


Tiling around the shower window is not as intricate as it may seem. However, with the proper tools and materials, you can quickly complete this project on the weekend.

Be sure to follow the manufacturer’s instructions and take your time to ensure that the job is done correctly.

Safety is paramount. Wear gloves, a dust mask, and eye protection when working with the backer board.

When cutting tile, use a wet saw to avoid breathing in dust particles.
