FLEXIPIXTILE™ can be used in almost all interior spaces of residential, commercial and hospitality applications, both on walls and ceilings. They are perfect for Kitchen backsplashes or as accent walls in offices, restaurants, fast food chains, bars and lobbies. However they are NOT recommended for applications where there might be direct continuous contact with water, or a possibility of high moisture in the air. (e.g. shower rooms, sauna rooms…) You can use them on other walls inside the bathroom though...

To answer your other concern, yes you can use them to cover the old tiles as long as the existing tiles are flat/level and non sanded.

Thank you!
