You, your tile guy, your glass guy, and your GC are having lunch together and you're buying.

Thanks for your completely useless response, Joseph. Hope you’re not this rude and and unhelpful to the people you GC for.

For anyone else who’s building and has the same question, I received an answer outside of Houzz. It apparently requires having the tile person install a Schluter glass track system.

We have a similar glass panel in our guest bathroom. My husband installed it but he had 30+ years working as a glazier. A glass company or professional shower door company would measure for custom glass after the tile is installed. They can caulk it into place or use half moon metal brackets. Minimum of 3/8” glass. We love it but the negative is there will be water on the floor.

Channel recessed in the floor and tile is laid alongside the track.

Actually, Joseph's comment is good advice. All those people Joseph listed all have to be on the same page about your desire (I doubt it is detailed on the construction documents) and having a lunch together is a good way to encourage good communication; or your next Houzz post may be, "My Tile Guy, Glass Guy, and GC Screwed Up My Shower Glass, What Do I Do?"

Laurie, what causes the water on your floor? Do you have only have one panel and an open area instead of a door like in the photos? Or do you have a door, but the track system itself allows water under the glass?

Mark, he didn’t in any way answer my question. I’m meeting with our tile person tomorrow with my project manager, who is with us at all of our meetings when we meet the new trades coming in. I understand the importance of communicating details to every person involved. What I asked was how the glass is installed this way so I would know what to communicate to my tile person and PM.

None of those are doors. They are fixed panels. Doors have hinges.

HU-785456157, we don’t get a lot of water but some will splash out while showering or while reaching out of shower because it’s a small shower. We have a single 34” x 79”, 3/8” glass panel with a 24” wide opening (no door). It’s installed curb to the ceiling. Our guest shower is small - 30x58. Our master bath walk in shower with a glass panel on a knee wall is much larger so we don’t get any water splashing out. Another thing to consider is air temperature because the shower can feel colder during the winter with no door. We live in southwest FL so heat loss it not problem for us. The no door helps air circulate after the shower which keeps mold from growing.

I also suspect that some of these are still photoshopped. If you had a recessed U Channel in the floor, it would still look like it was inset into the floor and likely create a dark reveal line as you could see through the glass somewhat.

OP Have a look at this video for Schluter DECO-SG. Also I can see how you would be frustrated at some of the comments here. There are people who like to be "comedians". It's best just to ignore them.

Thank you so much, Laurie!

Thanks, just-janni! I’ve seen a lot of photos that look like this, but it is still very possible they photoshopped them.

Thank you so much, Jeff Meeks! I actually watched that video last night, and it was super helpful to understand how it works. I met with our tile guy this morning, and he said he has done many bathrooms with Schluter deco OS. He said he prefers using it because the shower glass people won’t penetrate the waterproofing like they often do with the regular shower door hardware. And thank you for your understanding. The first guy’s comment wasn’t the worst I’ve seen by any means. I just get frustrated posting on here because I get way more rude or unhelpful comments than answers. I really appreciate people like you who actually help! Thanks again and have a great weekend!
