framing in a concealed cistern for wall hung toilet, how to screw/attach?

[StretchArmstrong]

Hi,

this week I need to frame in a concealed cistern toilet, before the tiler arrives

(perhaps not the right forum).

I have one of thse rak ecofix
(although it is a back to wall toilet, not wall hung.

I have bought some 20mm jackoboard to board in,

the frame is metal, so I screw into the metal frame? or do I stud frame all around it, without screwing into it?

any guidance welcomed.
thanks.

do I stud frame all around it, without screwing into it?

Yep, the metal frame is free standing, so no screwing to that. Create a wooden frame around it and screw the board to the wood.

thanks @Madrab the metal frame was secured to wall, but didnt attach the frame to it, built one around, and used jackoboard,

seemed to come out okay.
