🧩 What Is a Mosaic Wall Inlay?
A mosaic wall inlay is when tiles are installed directly into a wall surface, becoming part of the structure rather than sitting on top of it.
Think of it as:
- a feature embedded into your wall
- a permanent artistic installation

Unlike surface-mounted mosaics, inlays feel seamless—like they’ve always belonged there.
