| Location | What usually matters | Common AU choices |
|---|---|---|
| Shower floor | Fall to waste, slip resistance when wet, grout joints that still drain | Smaller mosaics or tiles that can form a plane to the waste |
| Bathroom floor (outside shower) | Slip when wet from splash, easy mopping | Porcelain with a suitable wet-area rating |
| Shower walls | Movement joints, waterproofing behind, niche detailing | Mid-format porcelain or ceramic; large slabs need specialist setting |
| Kitchen splashback | Heat behind cooktop, cleanability, grout colour | Ceramic, porcelain, glass, or a slab continuation |
Slip ratings, water absorption, and installation systems must match the location. Confirm with the tiler and current NCC / state guidance.
