What floor is this? - Tile Advice

[Redgoddess]

Hiya, so I've been asked to tile a wet room full floor and walls. I've been sent this photo of the floor, what material is this and is it going to be difficult to remove? It's my first bathroom/wetroom to tile as I'm new to the game.
TIA

Looks line an Altro vinyl floor. Needs removing.

Thanks Dave. Is this difficult to remove?

Use a heat gun to soften the adhesive, then it will pull up.
