I'm getting conflicting information from the plumbers/builders in my local pub about construction of this. I need to create a half height duct against a bathroom wall to house the shower pipework running into a concealed tap unit. Nobody can seem to agree on the timber size and type for the frame, I could use studwork but timber is more easily obtainable. I'll be putting tiling backing board on the frame and 8mm tiles on top. So, would 1'' square be good enough or 1'' X 2"" perhaps? What type of timber? treated or not?
