I have 4 units of bathroom in my 10yr old unit, currently planning on a makeover. As I'm trying as much as possible to avoid hacking due to dust and dirt which will mess up my whole house, someone suggested to use PVC Marble panel for the bathroom walls. Cleaner and cheaper apparently, also provide equal level of esthetics compared with real marble and glossy tiles.

Anyone with any idea of its durability?

Go check out Muro wall

Expensive. Twice the cost.

Will PVC Marble easily scratchable?

If rough handling yes.

For cleaning they suggest just use soft cloth with gentle soap and water will do. So basically its low maintenance and handling. Works well for not so strong and lazy people.
