I want to replace the shower in the main bathroom (over a bath). It looks like this (not same model) but I don't know if the fixings are a standard size? Tronico Single Function Thermostatic System | bathstore The current one is a bathstore one, and quite frankly is rubbish. I wouldn't replace from there, but with a quick google, I don't know if these type showers are all a standard size for the water inlet pipes (size of pipe and distance apart). Can anyone help?
