New wet room renovation,** duplicate 3 **

[MissBuilding1975]

In what order would you create a wet room? Renovation.

I have stripped the old wet room back to brick.

I just want your guys opinions on what order you would do things from materials used to completion. I will have concrete block benches, screed slope floor to the drain, and shower head mixer etc... but as for everything, what order and how would you create a new wet room. i.e batten walls, electrics, pipes etc, tanking etc......

Picture of my wet room is below.

thanks
