Shower Glass Panels: How to Template and Install

Make Small Bathrooms Look Bigger & Brighter

As Seen On
Shower Glass Panels for Tub Shower Combos

Shower glass panels make small showers look awesome.

Last week we shared quick tips for tiling a knee wall in a tub shower combo. Today you’ll see how we install glass shower panels on top of that knee wall.

The glass in this bathroom allows window light to fill the room. And the bathroom appears bigger than it is.

Learning to install glass shower panels will save a considerable amount of money during your DIY bathroom remodel.

Step 1: Make a Shower Glass Panel Template

How do you make the template for shower glass panels?

It requires a piece of wood, drywall, or in our case GoBoard – a foam waterproofing panel.

Typically a piece of 1/2 inch plywood would be our choice for a template because it’s fairly cheap.

We had extra GoBoard and decided to use it instead of plywood due to time restraints.

The house in today’s tutorial is a cape cod and the bathroom wall is slanted. This makes the template a bit more involved but not hard.

That said, the GoBoard is easier to cut than plywood and made the template easier to make.

Shower Glass Panels - GoBoard Template

We chose the height of the glass to be 60 inches above the tub. We weren’t concerned about water splashing over the glass.

And even if some did it’s not a big deal. Our tile floor is completely waterproof thanks to DITRA.

The height from the tub to knee wall marble was 19 inches.

Therefore the total height of the GoBoard template was 41 inches to make the top of the glass be 60 inches.

Shower Glass Panels - Total Glass Height

Our template width was 31 inches because the tub width was 29 inches.

We suggest having a hole for the shower rod about 2 inches from the glass edge. That would set the hole at 29 inches and right above the tub curb for a 29 inch tub.

In our video Steve shares how to plan and cut the GoBoard template to size so that it fits perfectly flush to the wall angle.

Check the template for any imperfections on the edges then send it to a glass fabricator. We used 3/8″ thick tempered glass for this shower.


Step 2: Cut the Metal Channels for the Glass

Shower glass panels need to sit in metal channels.

Angle grinders or miter saws can cut metal, but you’ll need the right blades for each respective tool. Schluter makes a metal cutting blade for their profiles. You can use it on the channels as well.

It’s best practice to bet miter saws up to full speed before lowering the blade.

Furthermore, don’t use a cordless miter saw for this.  They don’t have enough power and will bind in the metal.

We used an angle grinder for the odd wall angle.

The metal channel for the marble top was cut to 31 inches, the exact length of the glass.

Two pieces of metal made up the wall pieces, one for the vertical portion and one for the angled section. In the next step we’ll show how to mount them to the tile and marble.


Step 3: Mount the Metal Channels on the Tile Wall and Marble

Position the metal channels on the tile wall. They should be in the middle of the glass marble top.

Shower Glass Panels - Adding Metal Channels to Tile

Mark the position of the screws inside the channel using a marker.

Then cut the hole in the metal channel using a drill or an impact driver.

Shower Glass Panels - Drill Holes in Channel

Special drill bits are available for cutting metal.

Dry fit the metal channels on the wall and double check that they’re plumb. Then mark the hole positions on the tile using a marker.

Shower Glass Panels - Mark Holes on Tile

Drill through tile using diamond hole saws.

Milwaukee makes affordable hole saws for tile. In the video we give some extra tips on how to drill holes through porcelain.

We had to add plastic inserts in the tile since there wasn’t a stud where we needed it.

But you can also secure the metal channels to the wall using stainless steel screws.

Finally, adhere the horizontal piece of metal to the marble via the clear silicone.


Step 4: Add Shower Glass to the Metal Channels

Clean the edges of the shower glass with acetone so that the glass will adhere to the silicone.

Also clean the marble with just water and a rag.

Squeeze a bead of clear silicone into the channels.

Carefully slide the shower glass into the channels and embed it fully into the silicone.

Steve wedged a shim under the channel sitting on the marble and applied silicone to the channels/marble/tile transitions.

    Thanks for the info! The glass wall gives the tub a nice touch which I’ve never seen before.

    1. Jeff says:

      Hope it helps. These glass walls make a big difference in small bathrooms. I just hope our tenants take care of it

  2. Jake says:

    Excellent instruction gentlemen! I understand that you went with a 3/8″ tempered glass thickness. However, I have two pieces of 1/4″ tempered glass available from a sliding shower curtain that we decided not to install. We have already purchased a CRL anodized channel for the installation of this 1/4″ to our newly completed pony wall. In your opinion, is 1/4″ glass thick enough to support a shower curtain? Since our glass was not custom tempered, we won’t have the luxury of having a shower rod hole cut, so it will have to be the type that springs between the glass wall and tiled wall.

    1. That’s a good question Jake and frankly I’m not sure. Quarter inch is thin and I simply don’t know if it will hold that tension. Wish we had a better answer.

  3. Sam says:

    Awesome tutorial. One question, how do you install the shower rod?

    1. Thanks Sam for asking. There’s a hole in the glass for the one side of the shower rod and we had to drill holes in the tile for the other support.

  4. steve says:

    where do you get the glass cut to your template? did you cut it yourself?

    1. We took the template to a local glass company. They make the tempered glass panel and cut it to size.

  5. sam says:

    why not fasten channel to bottom marble ?


    1. Murlene Clark says:

      I am afraid of installing a shower rod that is anchored into a glass panel. One of the first things a person would do, if they slipped in the shower, is make a grab for the shower curtain. Would this break the glass?

  6. Maksim Hoxhaj says:

    is the waterproofing damaged when you drill the holes?

    1. Yes, but you can add silicone to the holes and to the panel where it meets the tile.

  7. Lynn says:

    I would love to do this in my shower. I only have a tiny high up window. So when I close the shower curtain it blocks all the light. You were very specific about the glass sizes but not the metal channel. Where can I found the channel, what size should the channel be to fit the glass, etc. I would have to order the channel online (small town problems) and Im worried about getting something to wide. I’d hate for water to get in or for the glass to wobble. Other than these questions your video was the most informative I found. Thank you for your great video.

  8. Melissa La Duca says:

    Would love to know how you set up a curtain rod with one tile wall and a glass knee wall on the other end of the tub. I have the same set up and cannot figure it out. We just used the tub up until now but our kids are bigger and need to install a shower curtain. The contractor did not cut a whole in the glass like many of the photos I see online

    1. Shana Franklin says:

      I would love to. Know the same.

  9. Kim says:

    We have a glass shower panel installed with metal channels. The glass appears to be short. It’s rests in the bottom channel about 1/4 in above the channel at the exposed end of the channel.
    The top of the glass is resting at the very edge of the channel on the end and I get a bit of rattling of the glass.
    Can silicone caulking we use to repair this or should we replace the glass with a better fit?

  10. Kim says:

    I love the look of the glass shower wall. It has made my tiny bathroom remodel appear larger and much brighter.
