Spend a bit more on taps. Oh and use copper ‘top hats’ rather than the plastic ones (the nuts that fix the tap to the bath/basin).

I refurbished ours few years ago – we kept the units (20 years old) as they were decent, but my wife wanted the bath turning 180 degrees. New electric shower unit, new quality taps, new soft flush mechanism (existing handle converted to ‘touch’, and I replaced the toilet bowl as that had a small crack.

Main issues with bathrooms are cheap connectors/top hats. As others have said, take time fitting the bath and get it all levelled and properly sealed in before tiling (fill bath, then silicone seal the sides to the walls). We found our bath hadn’t been fitted that well by the builders – 2 or 3 of the 5 adjustable legs weren’t tight to the floor.
