tiling on side of a bathroom cupboard help appreciated!

[fillpot9]

Hi i'm having an old bathroom ripped out and the room skimmed. Boiler is in the bathroom and the cupboard for the boiler is being built in after it's skimmed. and then the side of the boiler will be where the bath and shower go. so the shower will be attached to side of the cupboard.

I've attached plan (not to scale) what would be the recommended process for making sure this side of the boiler cupboard is suitable for tiling and attaching the shower too?

I don't have option to redesign layout or move the boiler.

Thanks

I would clad that wall in 12 mm hardibacker.

I would go for 12mm ply and 6mm hardiebacker, If only for the conveniece of installing shower fixtures.
