I need a thin plate (like metal) to lend extra support to a shower unit
chased into brick wall. What material would be strong and also can be
plastered over ? I would have just used plywood, but it's too thick. I
would be concerned about steel and even if galvanised it would have to
be drilled, so could rust with the moisture from the plaster. And I
think a brass sheet would be expensive ! Also the material would need
texture to be plastered over.
