I would like to change my shower head, however all the new shower
heads have a larger fitting on the hose than the taps I have. I
believe the standard size fitting on the hose nowadays is 1/2". Does
anyone know where I can get a hose with the smaller fitting on the
side which attaches to the taps and the standard size which fits onto
all the new showerheads? b.t.w. I'm based in London.
