Ideally you want the tiles sitting over the bath not slipped behind so....
Depending on how far you are willing to go i'd dot and dab plasterboard on to one wall making the whole room smaller 30mm shorter (assuming there are no doors on that wall)
or screw 20mm battens and plasterboard an area just behind the bath (so the boxing goes to the ceiling as it were)
or cut and shut the bath (Herbie style):smilewinkgrin:
