As nearly every basement floor, there's a slope towards the drain. I'm
in the middle of framing a bar with construction lumber and was wonder
what as proper:

The length of the bar is approx 8 feet. The difference in height
between the two ends is about 3/4". So the question is, do you build
the bar so it's level, or so that it's a consistent height from the
floor?

Is 3/4" to little to worry about either way?

TIA!
