Hi Dani!

That bathroom sounds stunning! You might try searching with keywords like "marble slab shower," "shower with ledge," or "back wall marble shower" on Houzz or on Pinterest to find somehting similar.

If you're on a platform with hashtags, you could try #marbleshower, #bathroomrenovation, or #luxurybathroom, which might bring it up.

If the post was recent, it may still be on the main feeds under recent bathroom or renovation posts. Good luck finding it—hope you can track it down!

If you need professional help with your project, you can contact me through my Houzz profile.
