Tiling around bath - better to fit tiles then bath or bath then tiles?

[Justice League]

So I am having my bathroom redone. I was quoted for using moisture board - but given the option to upgrade to using hard backer cement board or fully waterproof backer board (STS?) - they said the costs of using either would be the same.

Anyone have experience of these boards?

Also should the bath go in first and then tiles around it or should you tile the bathroom and then fit the bath?

Yes hardie backer is very good, adds stiffness to walls as it’s almost impossible to bend it (12mm).

Bath should ALWAYS be fitted before tiling.

To qualify that, you can tile up from a batten that would be above the bath and tile 95 % of the room. Then fit the bath and tile the cuts/ final tile down onto the bath.
i.e. you should never tile the wall and then push the bath up to a tiled surface.
