Sorry, should have had a better look at the picture. The flexible pipes are connected to copper pipe which then mates with the tap(s). A bit of a pain or at least beyond my ken, unless you’re willing to bin the old tap(s) and get new ones with longer tails - not expensive for Grohe on Amazon which have served me very well and seem decent quality.
Finding a new basin for what looks like a built in enclosure (of some vintage?) that’ll match all the old holes might be a bit of a tall order.
