I'm getting ready to tile my bathroom floor and tub surround. Our house is older (about 45 years old) and the walls/floors aren't exactly perpendicular. With that in mind, I'm wondering if I should align the tile to be exactly level with the floor/tub or align them so they're exactly level with the wall side (and slant slightly against the base).
Apologies if this doesn't make sense. I'll try to get some pictures up but the difference isn't major here so it might not be noticeable in a wide angle picture.

I think what you're saying is that the walls and the tub are not perpendicular and that you are going to tile the wall.
You want to know whether you should match a wall or the tub.
In situations like this my recommendation is usually to tile in a diamond pattern or to use smaller or subway or mosaic tiles such that long, contiguous grout lines are not obvious.
However, if you are going to have long contiguous grout lines I would start by leveling them to the tub and the ceiling, possibly splitting the difference. Consider that a grout line that get slightly wider or narrower as it progresses is less obvious than a tile line that slants upwards or downwards dramatically.
