That’s a pita, they were recommended by the plumbers who came to look at ours. We have something similar but it is hanging on in at the moment but when it goes it will need a new shower unit in a particularly stupid size and shape thanks to arsehole builders
Yeah, sent pictures to no avail and browsed seemingly every item on their website.
There are no details of the shower anywhere in the house paperwork so I have no idea what brand it is anyway.
