I'm seeking advice for my "future" wet bar. The house was built in 2006. I am in the process of finishing my basement (2x4 walls are up) and not exactly sure how to vent the wet bar correctly. The bar sits roughly 25' from the roughed in bathroom. I plan on running the drain pipe along the exterior walls to connect with my shower drain which flows to the ejector pump. I was curious if it would be too long of a horizontal run from the basement ceiling to connect the vent pipe to the existing rough in. I am assuming you couldn't vent it up and out of the house like a dryer vent (that would be easiest, but I'm looking for the right way). I ask this in fear of doing it the "pain in the a" way of running a new vent line straight up to the attic. I attached 2 pictures, 1 is a quick sketch of the basement layout (NE in the corner is where the bar is going, the other is a picture I took of the rough in plumbing right before they poured the concrete floor.
Thanks in advance,
