Default Slope on bath drain pipe.

If you can guarantee that only water is going down it and not solids

just another U bend then :-)

Yes, but you can't! Bits of human hair inevitably get into bath and
basin water - and these will collect at low points, and ultimately cause
blockages. It's important to make sure that any long straight pipe has a
downwards slope along its whole length, and doesn't have any dips in the
middle.
