I have a thermostatic shower (6 years old)
that is running hot and cold. My plumber wants to replace my whole shower, as there is no obvious manufacturer's mark to know what type of cartridge it has. He has told me it is cheaper to disconnect the plumbing to the old shower and add a new shower beside it and put panelling over the top. Is this normal? He said it would roughly cost £250. I live in a hard water area.
