Description
Dune Granadella Cielo Subway Tile in Gloss Finish is a 9mm porcelain subway tile backed by genuine European certification testing under the UNE-EN standard, rather than the generic dimensional listing common to commodity subway tiles. Its water absorption of ≤0.5% and breaking strength over 35 N/mm² put it in genuinely dense, low-porosity porcelain territory, with frost resistance and crazing resistance both independently confirmed.
Being rated for swimming-pool chemical resistance (Class A) and scoring a top 5/5 for stain resistance gives it real performance credentials for demanding wet-area or commercial applications, beyond what a typical decorative subway tile is tested against. Its Class 0 slip rating under UNE-EN 16165 should still be checked carefully against the specific application’s requirements, since slip classifications vary by intended use (dry floor, wet floor, barefoot area).

Where to Use
- Walls and splashbacks in kitchens and bathrooms
- Pool-adjacent wet areas, given its chemical resistance rating
- Commercial and residential applications requiring certified porcelain performance
How to Apply
- Plan the layout — choose a bond pattern before starting.
- Calculate quantity — order to the nearest square metre, allowing extra for cuts.
- Fix with a suitable tile adhesive — select an adhesive rated for the substrate and wet-area exposure.
- Grout — choose a contrasting or matching grout colour to suit the desired finished look.
Important Notes
- Confirm the Class 0 slip rating meets the specific application’s requirement before use on a floor.
- Order to the nearest whole square metre, allowing extra for cuts and pattern layout.
Most decorative subway tile listings carry little more than a size and finish description, which is why Granadella Cielo’s full UNE-EN test battery — water absorption, breaking strength, frost and crazing resistance, pool chemical resistance — stands out. Those figures give a specifier genuine confidence for demanding applications, rather than assuming a subway tile is purely decorative and untested for structural or environmental performance.
