The rough-in was done by a plumber many years ago. The planned location of the bar sink is now a stair landing, so obviously needs a change now.
The vent is 1-1/2"; the floor drain is 2"; the horizonal is 2". My plan is to replace the existing T at the old bar location with an elbow and replace the existing drain elbow with a sanitary T with the lower leg to the drain (2"), the upper leg to the sloped horizonal vent (elevate & change to 1-1/2?) and extend (with slope) the middle leg about 4 ft to the new sink location. Unsure if the sink leg can be 1-1/2 (preferred) or needs to be 2". From what I've read, thinking the sink end should be 16" AFF; not sure how far above T before elbow to sloped horizontal to existing vertical vent. 4"? Does this sound right?
Alternative is T at drain with center down to drain and 1 leg to vent and 1 leg to sink, but suspect that's not a good choice.
