Ply or backer board

[TheVictorian]

I need to tile this step into my utility room, I was going to build it out with timber at the front to cover the pipework then lay a sheet of ply over the step extending to the timber and bridging the pipes:

Is this the best way or should I be using backer board for this?

Many thanks

I think I would use backerboard as there is a possibility of some moisture working its way in from the outside.

Thank you. That's kind of what I was thinking, I just wanted to make sure it was strong enough really.

I was thinking of bedding it on some mortar as well as screwing it to the brickwork just to take out any unevenness of the surface, does this sound sensible?

Sounds like a plan.
