Sounds like you are essentially doing shower wallpaper -

Apparently done often in other parts of the world. A poster here did her shower in this company's product ad it was gorgeous (search wall and deco maybe on here?)

I think you could do this and it would be awesome based on what I see your skill set is in your pics.

Just noodle with a good shower person on the underlayment and think it through.

I considered it. - I have concrete walls, but wasn't sure I could find someone to execute correctly in my area - but your DIY skills look pretty epic.

Thanks - just_janni! I had no idea there was a product out there like that. Do you know how much it is, by chance?

In reading the directions, it sounds like it might be a thickened epoxy mixture that you use for the last step, which would be what I'd be doing, essentially - just all at once and then hanging it.

Thanks live_wire_oak - I definitely would make sure of that. Even though I think it'll work how I see it in my head - it's going to be fully prepped to replace the panels with tile or solid surface if need be.

I think I had a quote for a 7x5 shower (2 walls) and it was $1800 or so for material only

It is a beautiful bath!!

I just ordered this lighter colored amethyst wall mural to install on the back wall of the shower.

I figure if I do have any perfections in the epoxy coat, it’s better to do something with movement.

The Shower Wallpaper directions give me a great plan for what steps to take before adding the final panel. That really helps - thanks so much!

^^^^^ that is BEAUTIFUL!!!!!!

pngntx - are you continuing down this path and if so - turn on your DMs - would love to pick your brain on this concept.

Hi just_janni :)
Yes, I have the mural and just need to find the time to get the project going.

I think I’ve turned on DMs. Happy to answer whatever questions I can!

JJ - For the life of me I can’t figure out how to message you. Lol!

I’m attaching a photo that was my inspiration. I’m in a Facebook group for Stonecoat Countertops and this company posted the backsplash project.

Their website is https://m.facebook.com/CustomEpoxySurfacing/

I’m happy to chat about it with you. You can email me at ayerg73@gmail.com if I can’t figure out this message issue. :)

moving to email - THANKS!

@pngntx Did you complete this project? If so, how did you fare and please share pictures.

Hey there, Keen! I decided to go a different way on the project. I was concerned with the epoxy yellowing over time.

Instead I reached out to a commercial sign maker and had a panel custom printed that is weatherproof.

I got permission from a fav artist to use her work and had giant murals made. The IPE work is still in progress, but here’s the shower for now

WOW! That is gorgeous. Please share how you installed and sealed seams.

We waterproofed the walls then glued the the panels. I think we used liquid nails maybe? I’m not sure. Our contractor adhered them as if they were typical commercial FRP panels. We used clear silicone on the seams as well.
