As a rule, no. Ceramic wall tiles are made for vertical surfaces that carry no load. On a floor they can crack, wear quickly and become slippery when wet.
Some tiles are sold for both walls and floors, but those are floor tiles that also work on walls, not wall tiles that work on floors. The tile's test report and the factory's written use statement decide it, not the design or the catalogue page.
Why wall tiles fail on floors
- Strength: porous BIII wall tiles have a lower breaking strength than floor tiles, and furniture legs or dropped items can crack them.
- Glaze wear: wall glazes are usually softer and glossier, and foot traffic with grit wears visible paths.
- Slip: glossy wall glazes are not designed for slip resistance and can be dangerous when wet.
- Moisture: a porous body on a wet floor takes up water, which raises the risk of crazing and staining.
- Thickness: thin wall tiles are not made to bridge small gaps or uneven spots in a floor bed.
What a floor tile needs instead
A floor tile needs adequate breaking strength, a glaze with a suitable abrasion class, and slip resistance suited to the area. For glazed floor tiles, the abrasion class comes from ISO 10545-7 and is often called the PEI class. Our guide on PEI rating for tiles explains which class suits which floor.
Slip resistance is rated in different ways in different markets, such as the R rating under DIN 51130 or the DCOF value under ANSI A326.3. These are covered in slip resistance ratings for floor tiles. Wall tiles are rarely tested for either.
Grey areas
Some uses sit between wall and floor. Here is how to treat the common ones:
- A shower wall up to ceiling height is a wall, and wall tiles are fine.
- A shower floor is a wet floor and needs a floor tile with good slip resistance.
- A low-traffic dressing area may tolerate a light-duty floor tile, but still not a wall tile.
- Worktops and window sills face knocks and abrasion and need a floor-grade or porcelain tile.
- Small decorative inserts in a floor may use decor tiles only if the factory confirms floor use.
Protecting yourself as an importer
If a customer lays wall tiles on a floor and they fail, the complaint will still come back to you. Make the intended use clear on boxes, price lists and your website. Many factories print wall-use symbols on the carton; ask for them, and add them to your private-label boxes.
If you want one design on both walls and floors, source a wall tile and a matching floor tile, or a porcelain tile suited to both. The options are covered in ceramic versus porcelain wall tiles.
