Start with the water
Phoenix-area water is very hard, and every shower surface here fights calcium. Acrylic is smooth with no grout, so spots wipe off with a squeegee. Porcelain tile hides spots well, but cement grout lines collect scale. Epoxy grout solves most of that. Natural stone such as marble or travertine etches from hard water and from many cleaners, so we steer people away from it in showers unless they have soft water and will keep it sealed.

| Repair | Replace a single tile | Small chips patch; big damage means a new panel |
| Best in | Primary baths, long-term homes | Guest baths, rentals, fast jobs |
Does Arizona heat matter?
Both hold up when installed right. Walls move with big daily temperature swings. Acrylic panels flex a little, so they need solid backing and good sealant at the joints. Tile does not flex, so corners and changes of plane need flexible sealant, not grout. Cracked corners in a tiled shower usually mean someone grouted where they should have caulked.
What to watch for in a quote
- Acrylic: ask for the brand and panel thickness. Thin fiberglass or plastic kits are not the same product as solid acrylic panels.
- Tile: ask for porcelain, not soft ceramic, and ask which grout is included.
- Both: ask what waterproofing goes behind the walls and whether the pan is tested.
