Floor tiles on walls: usually yes. Porcelain floor tiles are strong enough for walls, but they're heavier, so check your wall can take the weight. As a general guide, including tiles and adhesive:
- Bare plasterboard (not skimmed), common on stud walls: around 32kg per square metre.
- Plastered walls, including plasterboard that's been skimmed: around 20kg per square metre.
Large, heavy tiles may need a cement or tile backer board instead. If you're not sure what your wall is made of, ask your tiler before ordering.
Wall tiles on floors: most ceramic wall tiles aren't suitable for floors, as they aren't strong enough to take foot traffic and can crack or wear. Please check the product page to see whether a tile is suitable for floors before buying.
