I’ve just done this job on my Santorin yesterday.
I took the sink off. Two screws on the front and four more on the bulkhead under the mirror.
It was then a very simple task. Only problem I had was the older fittings on the 12mm copper pipes. But you can put a conversion compression joint on each one to convert to the current flexible tap connectors.
I had to grind out the hole for the tap base for a slightly larger size.
