So we have just had a new shower installed.. Traditional thermostatic type with a lever. Looks great, except the white disk in the middle which has the H/C arrows on it turns out to be flimsy plastic and looks cheap and nasty.
Can I replace it Piglet John? What is it called? Where would I get one? I'd rather chrome or ceramic, if possible.
Thank you anyone who can make sense of what I'm asking
