GEOMIM is behind Caja by Maxx Royal in Bodrum, Muğla (2022). It is not a DIJA project — we had no hand in supplying it — but the record is specific enough about materials to be worth reading.
The architects credited these specific applications: spa walls: travertine.
For travertine, the nearest equivalent we stock is Travertine Silver Veincut.
We are not the right place to see this project's photography — that credit belongs at the source link below.
