Just bought a very nice recessed shower valve with fixed arm & head. Didn’t give it too much thought before buying but am now trying to work out how the hell you fix this lot into a cavity wall!
• Is it acceptable to run the pipe work up inside the wall cavity to the back of the mixer valve & shower head?
• What’s the usual method of mounting the valve - it’s 85mm deep?
• What do I support it on as it’s deeper than the blockwork? Is it acceptable to bracket off the inside face of the external brick skin?
• How do I support the fixed arm? The screwed portion behind the chrome face plate is not long enough to pass into the cavity & fix from behind, is it normal to have to extend this?
• How the hell do you get access to this lot to tighten all the pipe work, mixer valve & shower head supports?
Sorry so many questions but not having fitted a recessed unit before I expected it would be obvious on seeing it but it seems to be primarily designed to fit onto a thin panelled wall with rear access & the fitting instructions don’t give much of a clue!
