I have moved into a house where the three showers are all concealed installation. The tiles and pipe work all look great. I do want to change the shower fittings as they are a bit worse for wear. My question is can I only buy Hansgrohe shower valves and shower attachments to fit to the rough in or can any shower eg Arezzo, Crosswater be plumbed to this ? Am slightly worried that 3x HG showers are going to cost quite a bit.
