What moves the total most?
Changing the layout usually costs more than replacing fittings in the same positions because drainage, water supplies, studwork and finishes may all need alteration. Tiling area, shower specification, sanitaryware quality and whether the room needs replastering or electrical upgrades also have a large effect.
