Hmmm, that's a good idea, one I may copy when we get to that stage in a month or so. What has your tile guy said? I would wondering about water penetrating.

What are you doing around the entrance to your shower? Are you doing clips on the vertical edges or u-channel? Also, are you going to tile the vertical edges (the edges that come down and meet the curb) or the same material as your curb/threshold?

I have not met the tile guy yet, as we will not be ready for tile for at least 7 weeks. I am just trying to get input before I describe this idea to our GC.

I am not sure yet whether we are doing a slab or tile threshold. I plan on all vertical surfaces being tiled, although I guess I could frame the entire opening with slab remnants if there is a benefit to the added cost. We are going for a sleek, modern look, and I think a slab frame might look more traditional.

tempered glass may break, too.

Use any method you want, but make it easy to replace the glass.

Would the method I am suggesting make it difficult to replace the glass?

There was a discussion about this in earlier -- I finally found the thread. Scroll down to where Chays starts posting. There you'll find some discussion of the "embedding" options + pictures of what Chays did. A truly beautiful bathroom. While it's not a steam shower, I don't see why there would be any problems.

When our glass walls were being installed (with clips + silicone), I asked about the embedding option. The only issue the installer said he might have would be identifying leaks when they occurred. But he did not see that as a big issue.

Hope this helps.

No reason it cannot be done, it just requires prior planning and having your shower guy and glass guy on the same before the shower is even started.
